ABSTRACT OF THE DISCLOSURE
The present invention is directed towards a mechanical morcellator which includes a rotatable and relatively retractable cutting head. User manipulation varies the amount the cutting head extends out of a sheath, the amount of suction communicated to the cutting head, and the operation of a motor which rotatably drives the cutting head. Suction is communicated to the cutting head to aspirate the tissue fragmented by the cutting head. The morcellator is adapted to be inserted through a laparoscopic port site and directly fragment and aspirate tissue from within a patient's body.
Alternate embodiments of the present invention provide different cutting head extension and retraction devices. The morcellator of the present invention allows removal of tissue without the need for large entry incisions.

HECHANICAI IlORCELLaTOR
2BACl~GROlJND OF THB I~v~ rION
3FIE:LD OF TII~ IN~TIS~N -4The present invention is generally directed to tissue removal devices and, more particularly, to mechanical 6 morcellation devices.
7 D1~8CRIP~ON OF TBE RBI~ATED ART
8 During surgical procedures and, more particularly, tissue 9 removal procedures, it is desirable to limit the size of the entry incision to minimize the trauma experienced by the 11 patient. In the past, efforts to minimize entry incision size 12 have generally been limited due to the size of the tissue to 13 be removed and the need for access to the tissue.
14 However, in modern surgery access to the organ is provided by inserting one or more trocar and cannula to the 16 tissue cite. Thereafter, one or more laparoscopes are used 17 to view the tissue to be removed, and additional port sites 18 are used to gain access to the tissue to sever it from tissue 19 which is to remain. However, the entry incision must still be sized to allow removal of the severed tissue and, 21 therefore, the reduction in entry incision size is rather 22 limited even in more modern or recently developed surgical 23 procedures.
24 One system which has been developed to overcome this limitation i8 described in Lapaxoscopic Nephrectomy: A review 26 Or 16 Case~, Surgical ~aparoscopy & Endoscopy, Vol. 2, No. 1, 27 pp.29-34 tRaven Press, ~td., 1992), the disclosure o~ which 28 18 expressly incorporated herein in its entirety. This 29 publication describes a method ~or removing renal tissue using a mechanical morcellator. In this method o~ removal, the 31 kidney and associated renal ti8sue, after being severed from 32 the ureter, renal arteries, and veins, are placed in an . ' 1 impermeable containment bag. The neck of the bag is closed, 2 withdrawn from a laparoscopic port site, and reopened to gain 3 access to the tissue contained therein. Thereafter, with the 4 tissue remaining in the bag within the patient's body, a morcellator cutting head is introduced into the bag and 6 activated, fragmenting and aspirating the renal tissue. The 7 aspirated tissue is retained within a filtering chamber within 8 the morcellator handle, which must be cleaned following the 9 surgical procedure.
Although the morcellation device and method disclosed in 11 this reference represents an improvement over tissue removal 12 methods which require a large entry incision, several 13 undesirable structural and operational features remain.
14 The morcellation techniques known in the art do not provide a cover for the cutting head or allow relative 16 extension and retraction of the cutting head. Also, the known 17 morcellators do not provide means, whether electrical or 18 mechanical, to prevent the accidental or unintentional 19 actuation of the morcellator cutting head. Moreover, the known morcellators are not ergonomically designed, and are 21 rather bulky and cumbersome in use. These undesirable 22 features cooperate to create a mechanical morcellator which 23 is susceptible to accidental or unintentional actuation.
24 Therefore, there exists a need in the art for an effective mechanical morcellator which provides a relatively 26 movable cutting head and which includes means to prevent the 27 unintentional actuation of the morcellator cutting head.
28 There also exists a need Sor a mechanical morcellator which 29 aspirates Sragmented tissue to an exterior retention means and for a morcellator satisSying the deficiencies in the prior art 31 which is ergonomically designed to make handling and use 32 thereof more convenient Sor the surgeon.

18 DETAILED D138CRIPTION OF 1~15 PR~ RR13D ~BODIM~r 19 With reference to the drawing figures, the mechanical morcellator 10 of the present invention is shown to generally 21 include a handle 12, a sheath 14, a barrel 16, a drive tube 22 18, a rotary cutting head 20, and a trigger 22.
23 The handle 12, which i8 preferably formed in two mating 24 halves of polycarbonate or ABS plastic, provides a front aperture 24 through which the sheath 14, barrel 16, and drive 26 tube 18 extend. At the front aperture 24 the drive tube 18 27 i~ rotatably received within the barrel 16, which is slidably 28 received within the sheath 14. As illustrated, the sheath 14, 29 barrel 16, and drive tube 18 are coaxial and generally tubular in shape.
31 Preferably, the barrel 16 is stainless steel, having an 32 outside diameter of about 0.375 inches and a wall thickness 33 of about 0.016 inches, the drive tube 18 i8 plastic, having : . , 2121~61 1 an inside diameter of about 0.300 inches and an outside 2 diameter of about 0.330 inches, and the sheath 14 is TEFLON
3 or ethylene having an outside diameter of about 0.410 inches 4 and a wall thickness of about 0.010 inches.
The barrel 16 surrounds the drive tube 18 and extends 6 outwardly therewith from the handle 12 to the cutting head 20.
7 The barrel 16 is rigidly mounted to the handle to prevent the 8 barrel from rotating with the drive tube '8, and includes an 9 outwardly flared proximal end 26 into which is press fit a ~irst rear sleeve bearing 28. There is a gap of about 0.045 11 inches between the barrel 16 and the drive tube 18, allowing 12 the drive tube to rotate without frictional interference with 13 the barrel.
14 The barrel 16 is surrounded by the sheath 14 which extends outwardly therewith towards the cutting head 20. The 16 sheath 14 has a proximal end 30 (FIG. 2) and a tapered distal 17 end 32 (FIG. 3). The distal end 32 of the sheath 14 generally 18 surrounds the cutting head 20 while the sheath is in the 19 outward or "at restn position. The proximal end 30 of the sheat~ 14 is press fit into a cylindrical sheath receptacle 21 34 provided by the trigger 22, as illustrated.
22 Preferably, a sheath stop 36 is rearwardly spaced from 23 the sheath receptacle 34 to limit rearward longitudinal 24 movement of the sheath 14 to about 0.435 inches. The sheath stop 36, which is secured to the handle 12 and slip-fit over 26 the barrel 16, provides first and second latching surfaces A
27 and B which are releasably engaged by a trigger latch 38 28 associated with the trigger 22, as will be described 29 hereafter. Pre~erably, the latching surfaces A and B are about 0.400 inches apart.
31 As illustrated in FIG. 3, the cutting head 20 is 32 generally frustoconical in shape, having a proximal section 33 40 which i8 generally larger than a distal section 42.
34 Preferably, the proximal section 40 o~ the cutting head 20 has an outside diameter of about 0.300 inches to generally match 36 the inside diameter of the drive tube 18, and thereby allow ., - .

2~218~1 1 the proximal section 40 of the cutting head 20 to be press fit 2 into a distal end 44 of the drive tube 18 (FIG. 3). The -3 distal section 42 of the cutting head 20, which includes a 4 razor-sharp tip 46, preferably has a diameter of about 0.200 inches.
6 A distal end 48 of the barrel 16 extends past the distal ~-7 end 44 of the drive tube 18 and has press fit therein a front 8 sleeve bearing 50. The front sleeve bearing 50, which is 9 preferably made of TEFLON FEP, slidably fits over the cutting head 20 and is press fit into the barrel 16. The proximal 11 section 40 of the cutting head 20 is press fit into the distal 12 end 44 of the drive tube 18, and slidably and rotatably 13 received by the front sleeve bearing 50. ;~
14 The sheath 14 extends past the distal end 48 of the barrel 16, generally covering the distal section 42 of the 16 cutting head 20. The tapered distal end 32 of the sheath 14, 17 which provides an opening of about 0.280 inches through which 18 the cutting head extends, is generally coterminous with the 19 cutting head 20 when- the-trigger-22 is in the at-rest position. When the trigger is moved inwardly or rearwardly 21 (i.e. to the right in FIGS. 1 and 2) the cutting head 20 22 telescopingly extends out of the distal end 32 of the sheath 23 14, allowing the razor-sharp tip 46 of the cutting head 20 to 24 engage and fragment tissue.
The handle 12 also provides a downwardly directed opening 26 52 through which a rigid suction tube 54 extends. The suction 27 tube 54, which is rigidly attached to the handle 12, includes 28 inner and outer ends 56 and 58. The outer end 58 of the 29 suction tube 54 is received by an external flexible vacuum hose 60 ~FIG. 1) while the inner end 56, which is radially-31 outwardly flared, receives a proximal end 62 of the drive tube 32 18. The external flexible vacuum hose 60 connects to an 33 external suction source (not shown) and a tissue collection 34 means ~not shown). Preferably, the rigid suction tube 54 has an inside diameter of about 0.300 inches and a gentle 36 curvature, as illustrated, to provide unrestricted vacuum flow . ; . ~ . .
1 therethrough.
2 Midway along its length the suction tube 54 is separated 3 to allow mounting of a suction control valve 64 therein. A
4 cylindrical mounting plate 66 interconnects the separated portions of the suction tube 54 and includes a radially-6 outwardly projecting or annular surface 68 which defines a 7 slot 70 through which the suction control valve 64 extends, 8 as illustrated.
9 The suction control valve 64, which is integral with the trigger 22, defines an opening 72 which extends into the lumen 11 defined by the suction tube 54 when the trigger 22 is 12 inwardly-moved, as will be described more fully hereafter.
13 Preferably, the opening 72 is sized and positioned such that, 14 when the trigger 22 is in the fully-retracted position, the opening 72 coincides with the lumen provided by the suction 16 tube 54, thereby allowing maximum suction to be communicated 17 to the cutting head 20.
18 The flared inner end 56 of the rigid suction tube 54 has 19 press-fit therein a second rear sleeve bearing 74 which, in turn, is press fit onto the proximal end 62 of the drive tube 21 18. The cutting head 20, drive tube 18, rigid suction tube 22 54 and flexible vacuum hose ~0 comprise a suction flow path 23 which allows communication of fragmented tissue from the 24 rotary cutting head 20 to the external suction source and tissue collector.
26 A variable speed drive means is provided to rotatably 27 drive the drive tube 18 and, hence, the cutting head 20. The 28 drive means includes a motor 76, transmission 78, a switch 80, 29 and the trigger 22. The switch 80 comprises a first bronze io contact 82 pressed into the handle 12 ad~acent the cylindrical 31 mounting plate 66 and a second bronze contact 84 associated 32 with the trigger 22.
33 When the trigger 22 is in an at-rest or initial position 34 tFIG. 1), the switch 80 (i.e. the first and second contacts 82 and 84) represent an open circuit. ~hus, no current is 36 supplied to the motor 76, and the drive tube 18 and cutting . . , . , :

21218~1 1 head 20 are stationary. The motor 76 is electrically 2 connected to power via the switch 80 and a transformer or 3 control box 86 when the trigger 22 is in the inwardmost or 4 full-retracted position, as will be described more fully hereafter.
6 The control box 86 includes a rotary pot 88 to allow a 7 user to preset the maximum power available to the morcellator 8 10 and, hence, the maximum speed of the cutting head 20.
9 Electrical connectors 90 and appropriate lengths of electrical conductors 92 are between the control box 86 and the switch 11 80 and motor 76. Preferably, the conductors 90 are four-wire 12 cables and the connectors 92 are four-pin connectors.
13 The trigger 22 nests within a track provided by the 14 handle 12, and is manually movable by the surgeon, total ranqe of travel being generally equal to the sheath travel (i.e.
16 about 0.435 inches). The trigger 22, which is preferably 17 formed out of plastic, includes the metal trigger latch 38 18 which slidably extends out of a slot in the trigger 22. The 19 trigger 22 also includes an outwardly extending portion 94 which terminates in the cylindrical sheath receptacle 34.
21 The outwardly extending portion 94 defines an opening 22 throuqh which a hooked terminal end 96 of the trigqer latch 23 38 extends. The hooked terminal end 96 of the trigger latch 24 38 is operable to releasably engage the first and second latching surfaces A and B.
26 The trigger latch 38, which is resiliently biased to 27 extend through the trigger 22, pivots about pivot point C.
28 The second contact 84, which is slidably received by the 29 trigger 22, is press fit into the trigger latch 38 and moves therewith. When the trigger 22 and trigger latch 38 are in 31 the at-rest position shown in FIGS. 1 and 2, the hoo~ed 32 terminal end 96 is in engage~ent with the first latching 33 surface A, there i8 a gap of about 0.075 inches between the 34 trigger latch 38 and the trigger 22 at point D on FIG. 2, and the first and second contact8 82 and 84 are separated by 36 approximately 0.496 inches. When the trigger 22 and trigger . .. . ~
212186~
1 latch 38 are in the inwardmost or rearwardmost position, the 2 trigger and trigger latch are generally in contact at point 3 D, and the first and second contacts 82 and 84 are in 4 engagement.
A trigger return spring 98, which is mounted between the 6 trigger 22 and a portion of the handle, biases the trigger 22 7 and the trigger latch 38 to the at-rest or outward position.
8 Preferably, the trigger return spring 98 has an inside 9 diameter of about 0.200 inches and about three pounds maximum spring force.
11 The transmission 78, which transfers rotational motion 12 from the motor 76 to the drive tube 18, includes a spur gear 13 100, a driven gear 102, and a drive gear ~04. The spur gear 14 100, which is press fit onto the drive tube 18 intermediate the first and second rear sleeve bearings 28 and 74, meshes 16 with the drive gear 104. The drive gear 104 is connected to 17 the driven gear 102 via a transmission shaft 106. The driven 18 gear 102 meshes with a pinion gear 108 which is press fit onto 19 a motor output shaft 110. As will be recognized by one skilled in the art, the rotational motion of the motor output 21 shaft 110 is transferred to the driven gear 102 via the pinion 22 gear 108, and thereafter communicated to the spur gear lOo and 23 drive tube 18 via the transmission shaft 106 and drive gear 24 104.
The mechanical morcellator 10 of the present invention 26 operates in the following manner. After the tissue to be 27 removed is severed from the tissue to remain, the morcellator 28 10 i8 inserted via an existing laparoscope port site to the 29 location of the tissue. Optionally, the severed tissue is conrined within an impermeable bag tnot shown), preferably Or 31 nylon or the like, to prevent the migration Or tissue during 32 morcellation thereof. In the preferred embodiment the sheath 33 14, barrel 16, and drive tube 18 extend approximately ten 34 inches ~rom the handle 12, allowing the cutting head 20 to reach the tissue within the patient's body.

14 The barrel 16 is surrounded by the sheath 14 which extends outwardly therewith towards the cutting head 20. The 16 sheath 14 has a proximal end 30 (FIG. 2) and a tapered distal 17 end 32 (FIG. 3). The distal end 32 of the sheath 14 generally 18 surrounds the cutting head 20 while the sheath is in the 19 outward or "at restn position. The proximal end 30 of the sheat~ 14 is press fit into a cylindrical sheath receptacle 21 34 provided by the trigger 22, as illustrated.
22 Preferably, a sheath stop 36 is rearwardly spaced from 23 the sheath receptacle 34 to limit rearward longitudinal 24 movement of the sheath 14 to about 0.435 inches. The sheath stop 36, which is secured to the handle 12 and slip-fit over 26 the barrel 16, provides first and second latching surfaces A
27 and B which are releasably engaged by a trigger latch 38 28 associated with the trigger 22, as will be described 29 hereafter. Pre~erably, the latching surfaces A and B are about 0.400 inches apart.
31 As illustrated in FIG. 3, the cutting head 20 is 32 generally frustoconical in shape, having a proximal section 33 40 which i8 generally larger than a distal section 42.
34 Preferably, the proximal section 40 o~ the cutting head 20 has an outside diameter of about 0.300 inches to generally match 36 the inside diameter of the drive tube 18, and thereby allow ., - .

6 A distal end 48 of the barrel 16 extends past the distal ~-7 end 44 of the drive tube 18 and has press fit therein a front 8 sleeve bearing 50. The front sleeve bearing 50, which is 9 preferably made of TEFLON FEP, slidably fits over the cutting head 20 and is press fit into the barrel 16. The proximal 11 section 40 of the cutting head 20 is press fit into the distal 12 end 44 of the drive tube 18, and slidably and rotatably 13 received by the front sleeve bearing 50. ;~
14 The sheath 14 extends past the distal end 48 of the barrel 16, generally covering the distal section 42 of the 16 cutting head 20. The tapered distal end 32 of the sheath 14, 17 which provides an opening of about 0.280 inches through which 18 the cutting head extends, is generally coterminous with the 19 cutting head 20 when- the-trigger-22 is in the at-rest position. When the trigger is moved inwardly or rearwardly 21 (i.e. to the right in FIGS. 1 and 2) the cutting head 20 22 telescopingly extends out of the distal end 32 of the sheath 23 14, allowing the razor-sharp tip 46 of the cutting head 20 to 24 engage and fragment tissue.
The handle 12 also provides a downwardly directed opening 26 52 through which a rigid suction tube 54 extends. The suction 27 tube 54, which is rigidly attached to the handle 12, includes 28 inner and outer ends 56 and 58. The outer end 58 of the 29 suction tube 54 is received by an external flexible vacuum hose 60 ~FIG. 1) while the inner end 56, which is radially-31 outwardly flared, receives a proximal end 62 of the drive tube 32 18. The external flexible vacuum hose 60 connects to an 33 external suction source (not shown) and a tissue collection 34 means ~not shown). Preferably, the rigid suction tube 54 has an inside diameter of about 0.300 inches and a gentle 36 curvature, as illustrated, to provide unrestricted vacuum flow . ; . ~ . .
1 therethrough.
2 Midway along its length the suction tube 54 is separated 3 to allow mounting of a suction control valve 64 therein. A
4 cylindrical mounting plate 66 interconnects the separated portions of the suction tube 54 and includes a radially-6 outwardly projecting or annular surface 68 which defines a 7 slot 70 through which the suction control valve 64 extends, 8 as illustrated.
9 The suction control valve 64, which is integral with the trigger 22, defines an opening 72 which extends into the lumen 11 defined by the suction tube 54 when the trigger 22 is 12 inwardly-moved, as will be described more fully hereafter.
13 Preferably, the opening 72 is sized and positioned such that, 14 when the trigger 22 is in the fully-retracted position, the opening 72 coincides with the lumen provided by the suction 16 tube 54, thereby allowing maximum suction to be communicated 17 to the cutting head 20.
18 The flared inner end 56 of the rigid suction tube 54 has 19 press-fit therein a second rear sleeve bearing 74 which, in turn, is press fit onto the proximal end 62 of the drive tube 21 18. The cutting head 20, drive tube 18, rigid suction tube 22 54 and flexible vacuum hose ~0 comprise a suction flow path 23 which allows communication of fragmented tissue from the 24 rotary cutting head 20 to the external suction source and tissue collector.
26 A variable speed drive means is provided to rotatably 27 drive the drive tube 18 and, hence, the cutting head 20. The 28 drive means includes a motor 76, transmission 78, a switch 80, 29 and the trigger 22. The switch 80 comprises a first bronze io contact 82 pressed into the handle 12 ad~acent the cylindrical 31 mounting plate 66 and a second bronze contact 84 associated 32 with the trigger 22.
33 When the trigger 22 is in an at-rest or initial position 34 tFIG. 1), the switch 80 (i.e. the first and second contacts 82 and 84) represent an open circuit. ~hus, no current is 36 supplied to the motor 76, and the drive tube 18 and cutting . . , . , :

21218~1 1 head 20 are stationary. The motor 76 is electrically 2 connected to power via the switch 80 and a transformer or 3 control box 86 when the trigger 22 is in the inwardmost or 4 full-retracted position, as will be described more fully hereafter.
6 The control box 86 includes a rotary pot 88 to allow a 7 user to preset the maximum power available to the morcellator 8 10 and, hence, the maximum speed of the cutting head 20.
9 Electrical connectors 90 and appropriate lengths of electrical conductors 92 are between the control box 86 and the switch 11 80 and motor 76. Preferably, the conductors 90 are four-wire 12 cables and the connectors 92 are four-pin connectors.
13 The trigger 22 nests within a track provided by the 14 handle 12, and is manually movable by the surgeon, total ranqe of travel being generally equal to the sheath travel (i.e.
16 about 0.435 inches). The trigger 22, which is preferably 17 formed out of plastic, includes the metal trigger latch 38 18 which slidably extends out of a slot in the trigger 22. The 19 trigger 22 also includes an outwardly extending portion 94 which terminates in the cylindrical sheath receptacle 34.
21 The outwardly extending portion 94 defines an opening 22 throuqh which a hooked terminal end 96 of the trigqer latch 23 38 extends. The hooked terminal end 96 of the trigger latch 24 38 is operable to releasably engage the first and second latching surfaces A and B.
26 The trigger latch 38, which is resiliently biased to 27 extend through the trigger 22, pivots about pivot point C.
28 The second contact 84, which is slidably received by the 29 trigger 22, is press fit into the trigger latch 38 and moves therewith. When the trigger 22 and trigger latch 38 are in 31 the at-rest position shown in FIGS. 1 and 2, the hoo~ed 32 terminal end 96 is in engage~ent with the first latching 33 surface A, there i8 a gap of about 0.075 inches between the 34 trigger latch 38 and the trigger 22 at point D on FIG. 2, and the first and second contact8 82 and 84 are separated by 36 approximately 0.496 inches. When the trigger 22 and trigger . .. . ~
212186~
1 latch 38 are in the inwardmost or rearwardmost position, the 2 trigger and trigger latch are generally in contact at point 3 D, and the first and second contacts 82 and 84 are in 4 engagement.
A trigger return spring 98, which is mounted between the 6 trigger 22 and a portion of the handle, biases the trigger 22 7 and the trigger latch 38 to the at-rest or outward position.
8 Preferably, the trigger return spring 98 has an inside 9 diameter of about 0.200 inches and about three pounds maximum spring force.
11 The transmission 78, which transfers rotational motion 12 from the motor 76 to the drive tube 18, includes a spur gear 13 100, a driven gear 102, and a drive gear ~04. The spur gear 14 100, which is press fit onto the drive tube 18 intermediate the first and second rear sleeve bearings 28 and 74, meshes 16 with the drive gear 104. The drive gear 104 is connected to 17 the driven gear 102 via a transmission shaft 106. The driven 18 gear 102 meshes with a pinion gear 108 which is press fit onto 19 a motor output shaft 110. As will be recognized by one skilled in the art, the rotational motion of the motor output 21 shaft 110 is transferred to the driven gear 102 via the pinion 22 gear 108, and thereafter communicated to the spur gear lOo and 23 drive tube 18 via the transmission shaft 106 and drive gear 24 104.
The mechanical morcellator 10 of the present invention 26 operates in the following manner. After the tissue to be 27 removed is severed from the tissue to remain, the morcellator 28 10 i8 inserted via an existing laparoscope port site to the 29 location of the tissue. Optionally, the severed tissue is conrined within an impermeable bag tnot shown), preferably Or 31 nylon or the like, to prevent the migration Or tissue during 32 morcellation thereof. In the preferred embodiment the sheath 33 14, barrel 16, and drive tube 18 extend approximately ten 34 inches ~rom the handle 12, allowing the cutting head 20 to reach the tissue within the patient's body. The morcellator 36 i8 not in operation during insertion and the electrical and . ~. . .. . . .
1 mechanical means described previously prevent the 2 unintentional operation thereof.
3 If the tissue to be removed is to be fragmented and 4 aspirated without being preliminarily captured in an impermeable bag, the surgeon views the tissue to be removed 6 and the distal ends 32 and 44 of the sheath 14 and cutting 7 head 20 via a laparascope ~not shown). Otherwise, the tissue 8 is preliminarily captured within an impermeable bag, the mouth 9 of the bag is withdrawn from one of the laparoscopic ports, and the distal ends 32 and 44 of the sheath 14 and the cutting 11 head 20 are inserted into the bag via the open mouth.
3 If the tissue to be removed is to be fragmented and 4 aspirated without being preliminarily captured in an impermeable bag, the surgeon views the tissue to be removed 6 and the distal ends 32 and 44 of the sheath 14 and cutting 7 head 20 via a laparascope ~not shown). Otherwise, the tissue 8 is preliminarily captured within an impermeable bag, the mouth 9 of the bag is withdrawn from one of the laparoscopic ports, and the distal ends 32 and 44 of the sheath 14 and the cutting 11 head 20 are inserted into the bag via the open mouth.
12 In either case, the trigger 22 and trigger latch 38 are 13 rearwardly or inwardly moved aqainst the bias of the trigger 14 return spring 98. Rearward or inward force on the trigger latch 38 initially causes the trigger latch 38 to pivot about 16 pivot point C and d sengage the hooked terminal end 96 of the 17 trigger latch 38 from the first latching surface A.
18 Thereafter, the trigger 22 and trigger latch 38 are free to 19 move rearwardly-against the bias of the trigger return spring 98 until the cylindrical sheath receptacle 34 engages the 21 sheath stop 36. Rearward movement of the trigger 22 and 22 associated sheath receptacle 34 simultaneously moves the 23 sheath 14 rearwardly, exposing the distal section 42 of the 24 cutting head 20 and the razor sharp tip 46 provided thereby.
As the trigger 22 moves rearwardly, the suction control 26 valve 64 provided thereby and, more specifically, the opening 27 72 in the sUction control valve 64, extends into the lumen 28 defined by the suction tube 54. The further the trigger 22 29 is depressed, the more the opening 72 extends into the lumen of the suction tube 54, thus communicating suction to the 31 cutting head 20 in proportion to the amount the cutting head 32 extends out of the sheath 14.
33 During movement of the trigger 22 and exposure of the 34 cutting head 20, the first and second contacts 82 and 84 are spaced from each other and, hence, the motor 76 is not 36 connected to power and does not rotatably drive the cutting 212~ 861 1 head 20 via th~ drive tube 18. When the trigger approaches 2 its inwardmost position, the combination of trigger 22 and 3 trigger latch 38 movement allows the first and second contacts 4 82 and 84 to engage and connect the motor 76 to power, the level of which was preset by user manipulation of the control 6 box 86. Rotational motion of the motor output shaft 110 is 7 transferred througb the transmission 78 and drive tube 18 to 8 the cutting head 20.
9 The surgeon moves the razor sharp tip 46 of the cutting head 20 into engagement with the tissue to be removed, 11 ~ragmenting the tissue. The fragmented tissue, typically ir.
12 the form of a cylindrical or rod-like core of tissue, is 13 thereafter aspirated into the external tissue collection means 14 via the drive tube 18, suction tube 54, and vacuum hose 60.
The core of tissue may simplify and expedite examination and 16 study of the severed tissue as compared to the ground-up 17 tissue which results from prior art morcellators.
18 When the procedure is complete, the surgeon merely 19 releases the trigger 22 which opens the switch 80,--turns off the motor 76, precludes communication of suction to the 21 cutting head 20, and returns the sheath 14 to its at-rest 22 position covering the cutting head 20.
23 If, while the trigger 22 is being rearwardly moved 24 between the first and second latching surfaces A and B, the trigger latch 38 iæ released, the trigger return spring 98 26 will cause the trigger latch 38 to pivot about pivot point C
27 and thereby return the trigger latch 38 to its at-rest or 28 outward position. Further rearward movement of the trigger 29 22 will cause the hooked terminal end 96 to engage the second latch sur~ace B, preventing further rearward movement of the 31 trigger 22 and sheath 14 until the trigger latch 38 is 32 depressed by the user. Also, if the trigger 22 and trigger 33 latch 38 are released between the first and second latching 34 surfaces A and B, and the sheath 14 is rearwardly pushed, perhaps due to frictional contact with tissue ~urrounding the 36 sheath 14, the second latching surface B will be engaged by 1 the hooked terminal end 96 of the trigger latch 38 and prevent 2 the further rearward movement of the sheath 14 until the 3 trigger latch 38 is rearwardly-moved against the bias of the 4 trigger return spring 98.
As should be clear from the foregoing, the combination 6 of the relatively moveable sheath 14, the trigger latch 38, 7 and the switch 80 cooperate to provide a mechanical 8 morcellator which prevents the accidental or unintentional 9 actuation or operation thereof. Specifically, there is a range of motion to the trigger 22 and trigger latch 38 which 11 i8 necessary in order to actuate the motor 76. Moreover, 12 accidental actuation of the razor sharp tip 46 of the cutting 13 head 20 is not possible without first rearwardly moving the 14 trigger 22 and trigger latch 38. Therefore, the risk of accidental or unintentional actuation of the razor sharp tip 16 46 is significantly reduced as compared to known mechanical 17 morcellators.
18 Second and third embodiments of the present invention are 19 illustrated in FIGS. 4 and 5, respectively, wherein, when possible, the reference numerals used to describe the first 21 embodiment illustrated in FIGS. 1-2 have been employed. As 22 will be apparent with reference to the drawing figures, 23 several structural features of the first embodiment are 24 present in the second and third embodiments, and will not be further described herein. Also, the details of the cutting 26 head shown in FIG. 3 are unchanged in the second and third 27 embodiments, and, therefore, will not be further described 28 herein.
29 The morcellator shown in FIG. 4 includes the handle 12, sheath 14, barrel 16, drive tube 18, cutting head 20 IFIG. 3), 31 and trigger 22. The handle 12, which is preferably formed in 32 two mating halves of polycarbonate or A~S plastic, provides 33 a front aperture 24 through which the sheath 14, barrel 16, 34 and drive tube 18 extend. Surrounding the front aperture 24, the handle 12 provides an enlarged nose portion 25 which 36 provides a cylindrical cavity projecting rearwardly from the ' ~
.'` `, .~ ~ `' , . ' ~ ' '~""~'' ` ' 21218~1 1 front aperture 24.
2 The sheath 14 has a proximal end 30 and a tapered distal 3 end 32 (FIG. 3). The proximal end 30 of the sheath 14 is 4 press fit into an exteriorly threaded bushing 31 which, in turn, i8 threaded into an annular or ring-shaped rotary sheath 6 knob 33. The sheath 14, barrel 16, and drive tube 18 extend 7 through a central opening provided by the sheath knob 33. The 8 rotary sheath knob 33 includes a relatively thick cylindrical 9 portion 43, which is received by the cylindrical cavity de~ined by the enlarged nose portion 25, and a thinner 11 elongated cylindrical portion 45, which extends inwardly from 12 the thick cylindrical portion 43 towards a sheath stop 36, as 13 illustrated. The elongated cylindrical portion 45 includes 14 an annular rim 27 which engages a stop 29 to help retain the sheath knob 33 within the handle 12.
16 The sheath knob 33 and, more particularly, the thick 17 cylindrical portion 43, is accessible to the user for 18 manipulation via one or more openings (not shown) in the 19 handle 12. As mounted within the handle 12, the sheath knob 33, which is only capable of rotary movement, threadably 21 engages the bushing 31 and compels the bushing 31 and, hence, 22 the sheath 14, which is press-fit therein, to move longitudi-23 nally or lengthwise. Thus, rotary movement of the sheath knob 24 33 is translated into longitudinal movement of the sheath 14, thereby allowing the user to vary the amount the cutting head 26 20 extends out of the sheath 14.
27 Preferably, the sheath stop 36 is rearwardly or inwardly 28 spaced from a terminal end 37 of the sheath 14 and threaded 29 bushing 31 to limit rearward longitudinal movement of the sheath 14 to about 0.435 inche~. The sheath stop 36, which 31 is secured to the handle 12 and slip-fit over the barrel 16, 32 also provides first and second latching surfaces A and B which 33 are releasably engaged by a trigger latch 38 associated with 34 the trigger 22. Preferably, the latching surfaces A and B are about 0.400 inches apart.
36 A variable speed drive means is provided to rotatably .
2121861 ~
1 drive the drive tube 18 and, hence, the cutting head 20. The 2 drive means includes the motor 76, transmission 78, switch 81, 3 and the trigger 22. The switch 81 is mounted to the handle 4 12 adjacent the cylindrical mounting plate 84 and is actuated when the trigger 22 is moved to its inwardmost or rearwardmost 6 position, as will be described hereafter.
7 The trigger 22 nests within a track provided by the 8 handle 12, and is manually movable by the surgeon, total range g of travel being about 0.445 inches. The trigger 22 is preferably made out of plastic and includes a metal trigger 11 latch 38 which slidably extends out of a slot in the trigger 12 22. The trigger latch 38 pivots about pivot point C and in-13 cludes a hooked terminal end 96 which is operable to 14 releasably engage the first and second latching surfaces A and B. The trigger latch 38 also includes an inwardly directed 16 portion 39 which is operable to actuate the switch 81, as will 17 be described more fully hereafter.
18 When the trigger 22 and trigger latch 38 are in the at-19 rest position shown in FIG. 4, the hooked terminal end 96 is in engagement with the first latching surface A, and there is 21 a gap of about 0.075 inches between the trigger latch 38 and 22 the trigger 22 at point D on FIG. 4. A trigger return spring 23 98, which is mounted between the trigger 22 and a portion of 24 the handle 12, biases the trigger 22 and the trigger latch 38 to the at-rest or outward position. When the trigger 22 and 26 trigger latch 38 are in the inwardmost or rearwardmost 27 position, the inwardly directed portion 39 is in engagement 28 with tha switch 81, and the trigger and trigger latch are 29 generally in contact at point D.
The mechanical morcellator 10 of the second embodiment 31 operates in the following manner. Following severance of the 32 tissue to be removed from the tissue to remain, the 33 morcellator 10 i8 inserted via an existing laparoscope port.
34 Optionally, and as discussed with reference to the operation o~ the first embodiment of the present invention, the severed 36 tissue is confined or placed within an impermeable bag/

21218~1 1 preferably of nylon or the like, to prevent the migration of 2 tissue during morcellation thereof. In the preferred 3 embodiment the sheath 14, barrel 16, and drive tube 18 extend 4 approximately 9.70 inches from the handle 12, allowing the cutting head 20 to reach the tissue within the patient's body.
6 The morcellator 10 is not in operation during insertion and 7 the electrical and mechanical means described previously 8 prevent the unintentional operation thereof.
9 While the surgeon views the tissue to be removed and the distal ends 32 and 44 of the sheath 14 and cutting head 20, 11 the rotary sheath knob 33 i8 manipulated or rotated by the 12 surgeon, causing the bushing 31 and sheath 14 to move 13 rearwardly (i.e., to the right as viewed in FIG. 4) and expose 14 the cutting head 20. The surgeon discontinues his adjustment or manipulation of the rotary sheath knob 33 when the cutting 16 head 20 extends out of the sheath 14 the desired amount.
18 Thereafter, the trigger 22 and trigger latch 38 are free to 19 move rearwardly-against the bias of the trigger return spring 98 until the cylindrical sheath receptacle 34 engages the 21 sheath stop 36. Rearward movement of the trigger 22 and 22 associated sheath receptacle 34 simultaneously moves the 23 sheath 14 rearwardly, exposing the distal section 42 of the 24 cutting head 20 and the razor sharp tip 46 provided thereby.
As the trigger 22 moves rearwardly, the suction control 26 valve 64 provided thereby and, more specifically, the opening 27 72 in the sUction control valve 64, extends into the lumen 28 defined by the suction tube 54. The further the trigger 22 29 is depressed, the more the opening 72 extends into the lumen of the suction tube 54, thus communicating suction to the 31 cutting head 20 in proportion to the amount the cutting head 32 extends out of the sheath 14.
33 During movement of the trigger 22 and exposure of the 34 cutting head 20, the first and second contacts 82 and 84 are spaced from each other and, hence, the motor 76 is not 36 connected to power and does not rotatably drive the cutting 212~ 861 1 head 20 via th~ drive tube 18. When the trigger approaches 2 its inwardmost position, the combination of trigger 22 and 3 trigger latch 38 movement allows the first and second contacts 4 82 and 84 to engage and connect the motor 76 to power, the level of which was preset by user manipulation of the control 6 box 86. Rotational motion of the motor output shaft 110 is 7 transferred througb the transmission 78 and drive tube 18 to 8 the cutting head 20.
9 The surgeon moves the razor sharp tip 46 of the cutting head 20 into engagement with the tissue to be removed, 11 ~ragmenting the tissue. The fragmented tissue, typically ir.
12 the form of a cylindrical or rod-like core of tissue, is 13 thereafter aspirated into the external tissue collection means 14 via the drive tube 18, suction tube 54, and vacuum hose 60.
The core of tissue may simplify and expedite examination and 16 study of the severed tissue as compared to the ground-up 17 tissue which results from prior art morcellators.
18 When the procedure is complete, the surgeon merely 19 releases the trigger 22 which opens the switch 80,--turns off the motor 76, precludes communication of suction to the 21 cutting head 20, and returns the sheath 14 to its at-rest 22 position covering the cutting head 20.
23 If, while the trigger 22 is being rearwardly moved 24 between the first and second latching surfaces A and B, the trigger latch 38 iæ released, the trigger return spring 98 26 will cause the trigger latch 38 to pivot about pivot point C
27 and thereby return the trigger latch 38 to its at-rest or 28 outward position. Further rearward movement of the trigger 29 22 will cause the hooked terminal end 96 to engage the second latch sur~ace B, preventing further rearward movement of the 31 trigger 22 and sheath 14 until the trigger latch 38 is 32 depressed by the user. Also, if the trigger 22 and trigger 33 latch 38 are released between the first and second latching 34 surfaces A and B, and the sheath 14 is rearwardly pushed, perhaps due to frictional contact with tissue ~urrounding the 36 sheath 14, the second latching surface B will be engaged by 1 the hooked terminal end 96 of the trigger latch 38 and prevent 2 the further rearward movement of the sheath 14 until the 3 trigger latch 38 is rearwardly-moved against the bias of the 4 trigger return spring 98.
As should be clear from the foregoing, the combination 6 of the relatively moveable sheath 14, the trigger latch 38, 7 and the switch 80 cooperate to provide a mechanical 8 morcellator which prevents the accidental or unintentional 9 actuation or operation thereof. Specifically, there is a range of motion to the trigger 22 and trigger latch 38 which 11 i8 necessary in order to actuate the motor 76. Moreover, 12 accidental actuation of the razor sharp tip 46 of the cutting 13 head 20 is not possible without first rearwardly moving the 14 trigger 22 and trigger latch 38. Therefore, the risk of accidental or unintentional actuation of the razor sharp tip 16 46 is significantly reduced as compared to known mechanical 17 morcellators.
18 Second and third embodiments of the present invention are 19 illustrated in FIGS. 4 and 5, respectively, wherein, when possible, the reference numerals used to describe the first 21 embodiment illustrated in FIGS. 1-2 have been employed. As 22 will be apparent with reference to the drawing figures, 23 several structural features of the first embodiment are 24 present in the second and third embodiments, and will not be further described herein. Also, the details of the cutting 26 head shown in FIG. 3 are unchanged in the second and third 27 embodiments, and, therefore, will not be further described 28 herein.
29 The morcellator shown in FIG. 4 includes the handle 12, sheath 14, barrel 16, drive tube 18, cutting head 20 IFIG. 3), 31 and trigger 22. The handle 12, which is preferably formed in 32 two mating halves of polycarbonate or A~S plastic, provides 33 a front aperture 24 through which the sheath 14, barrel 16, 34 and drive tube 18 extend. Surrounding the front aperture 24, the handle 12 provides an enlarged nose portion 25 which 36 provides a cylindrical cavity projecting rearwardly from the ' ~

2 The sheath 14 has a proximal end 30 and a tapered distal 3 end 32 (FIG. 3). The proximal end 30 of the sheath 14 is 4 press fit into an exteriorly threaded bushing 31 which, in turn, i8 threaded into an annular or ring-shaped rotary sheath 6 knob 33. The sheath 14, barrel 16, and drive tube 18 extend 7 through a central opening provided by the sheath knob 33. The 8 rotary sheath knob 33 includes a relatively thick cylindrical 9 portion 43, which is received by the cylindrical cavity de~ined by the enlarged nose portion 25, and a thinner 11 elongated cylindrical portion 45, which extends inwardly from 12 the thick cylindrical portion 43 towards a sheath stop 36, as 13 illustrated. The elongated cylindrical portion 45 includes 14 an annular rim 27 which engages a stop 29 to help retain the sheath knob 33 within the handle 12.
16 The sheath knob 33 and, more particularly, the thick 17 cylindrical portion 43, is accessible to the user for 18 manipulation via one or more openings (not shown) in the 19 handle 12. As mounted within the handle 12, the sheath knob 33, which is only capable of rotary movement, threadably 21 engages the bushing 31 and compels the bushing 31 and, hence, 22 the sheath 14, which is press-fit therein, to move longitudi-23 nally or lengthwise. Thus, rotary movement of the sheath knob 24 33 is translated into longitudinal movement of the sheath 14, thereby allowing the user to vary the amount the cutting head 26 20 extends out of the sheath 14.
27 Preferably, the sheath stop 36 is rearwardly or inwardly 28 spaced from a terminal end 37 of the sheath 14 and threaded 29 bushing 31 to limit rearward longitudinal movement of the sheath 14 to about 0.435 inche~. The sheath stop 36, which 31 is secured to the handle 12 and slip-fit over the barrel 16, 32 also provides first and second latching surfaces A and B which 33 are releasably engaged by a trigger latch 38 associated with 34 the trigger 22. Preferably, the latching surfaces A and B are about 0.400 inches apart.
36 A variable speed drive means is provided to rotatably .
2121861 ~
1 drive the drive tube 18 and, hence, the cutting head 20. The 2 drive means includes the motor 76, transmission 78, switch 81, 3 and the trigger 22. The switch 81 is mounted to the handle 4 12 adjacent the cylindrical mounting plate 84 and is actuated when the trigger 22 is moved to its inwardmost or rearwardmost 6 position, as will be described hereafter.
7 The trigger 22 nests within a track provided by the 8 handle 12, and is manually movable by the surgeon, total range g of travel being about 0.445 inches. The trigger 22 is preferably made out of plastic and includes a metal trigger 11 latch 38 which slidably extends out of a slot in the trigger 12 22. The trigger latch 38 pivots about pivot point C and in-13 cludes a hooked terminal end 96 which is operable to 14 releasably engage the first and second latching surfaces A and B. The trigger latch 38 also includes an inwardly directed 16 portion 39 which is operable to actuate the switch 81, as will 17 be described more fully hereafter.
18 When the trigger 22 and trigger latch 38 are in the at-19 rest position shown in FIG. 4, the hooked terminal end 96 is in engagement with the first latching surface A, and there is 21 a gap of about 0.075 inches between the trigger latch 38 and 22 the trigger 22 at point D on FIG. 4. A trigger return spring 23 98, which is mounted between the trigger 22 and a portion of 24 the handle 12, biases the trigger 22 and the trigger latch 38 to the at-rest or outward position. When the trigger 22 and 26 trigger latch 38 are in the inwardmost or rearwardmost 27 position, the inwardly directed portion 39 is in engagement 28 with tha switch 81, and the trigger and trigger latch are 29 generally in contact at point D.
The mechanical morcellator 10 of the second embodiment 31 operates in the following manner. Following severance of the 32 tissue to be removed from the tissue to remain, the 33 morcellator 10 i8 inserted via an existing laparoscope port.
34 Optionally, and as discussed with reference to the operation o~ the first embodiment of the present invention, the severed 36 tissue is confined or placed within an impermeable bag/
.. `...~.: , ~ ` -, . . . ~ . - , .

21218~1 1 preferably of nylon or the like, to prevent the migration of 2 tissue during morcellation thereof. In the preferred 3 embodiment the sheath 14, barrel 16, and drive tube 18 extend 4 approximately 9.70 inches from the handle 12, allowing the cutting head 20 to reach the tissue within the patient's body.
6 The morcellator 10 is not in operation during insertion and 7 the electrical and mechanical means described previously 8 prevent the unintentional operation thereof.
9 While the surgeon views the tissue to be removed and the distal ends 32 and 44 of the sheath 14 and cutting head 20, 11 the rotary sheath knob 33 i8 manipulated or rotated by the 12 surgeon, causing the bushing 31 and sheath 14 to move 13 rearwardly (i.e., to the right as viewed in FIG. 4) and expose 14 the cutting head 20. The surgeon discontinues his adjustment or manipulation of the rotary sheath knob 33 when the cutting 16 head 20 extends out of the sheath 14 the desired amount.
17 Thereafter, the trigger 22 and trigger latch 38 are rear-18 wardly or inwardly moved against the bias of the trigger 19 return spring 98. Rearward force on the trigger 22 and trigger latch 38 initially causes the trigger latch 38 to 21 pivot about pivot point C and disengage the hooked terminal 22 end 96 from the first latching surface A. Thereafter, the 23 trigger 22 and trigger latch 38 are free to move rearwardly 24 against the bias of the trigger return spring 98. Naturally, if the trigger latch 38 is released while the trigger 22 is 26 being rearwardly moved between the first and second latching 27 surfaces A and B, the trigger return spring 98 will cause the 28 trigger latch to pivot about the pivot point C and, thus, 29 return the trigger latch 38 to its at-rest or outward position. This, in turn, will cause the hooked terminal end 31 96 of the trigger latch 38 to engage the second latch surface 32 B, and thereby prevent further rearward movement of the 33 trigger 22 until the trigger latch 38 i8 depressed by the 34 user.
As the trigger 22 moves rearwardly, the suction control 36 valve 64 provided thereby and, more specifically, the opening .:. . . .
1 72 in the suction control valve 64, extends into the lumen 2 defined by the suction tube 54. The further the trigger 22 3 is rearwardly moved, the more the opening 72 extends into the 4 lumen, thus communicating relatively more suction to the 5 cutting head 20. -6 During movement of the trigger 22 and exposure of the 7 cutting head 20, the switch 81 is open and, hence, the motor 8 76 is not connected to power and does not rotatably drive the 9 cutting head 20. When the trigger 22 approaches its inwardmost or rearwardmost position, the combination of 11 trigger 22 and trigger latch 38 movement allows the inwardly 12 directed portion 39 of the trigger latch 38 to contact and 13 actuate the switch 81 and thereby connect the motor 76 to 14 power. Rotational motion of the motor output shaft 110 is lS transferred through the transmission 78 and drive tube 18 to -16 the cutting head 20, as discussed previously. "
17 The surgeon moves the razor sharp tip 46 of the cutting 18 head 20 into engagement with the tissue to be removed, 19 fragmenting the tissue. The fragmented tissue, typically a rod-like or cylindrical core, is thereafter aspirated into the 21 external tissue collection means via the drive tube 18, 22 suction tube 54, and YaCuUm hose 60. At any time during the 23 procedure, the surgeon can adjust the amount the cutting head 24 20 extends out of the sheath 14 by manipulating the rotary sheath Xnob 33. This can be done either while the cutting 26 head i8 rotating or, by releasing the trigger 22 to disconnect 27 the motor 76 from power, when the cutting head 20 i8 28 stationary.
29 When the procedure is complete, the surgeon merely releases the trigger which opens the switch 81, turns off the 31 motor 76, and precludes communication of suction to the 32 cutting head 20. Thereafter, the rotary sheath knob 33 is 33 returned to its initial or outwardmost position, allowing the 34 sheath 14 to extend over and cover the cutting head 20, and the morcellator 10 i8 withdrawn from the port.
36 With reference to FIG. 5, the third embodiment of the , ~: . - ;
2 1 2 ~
1 mechanical morcellator of the present invention is shown. The 2 third embodiment includes the handle 12, sheath 14, barrel 16, 3 drive tube 18, cutting head 20 (FIG. 3), and trigger 22. The 4 handle 12, which is preferably formed in two mating halves of polycarbonate or ABS plastic, provides a front aperture 24 6 through which the sheath 14, barrel 16, and drive tube 18 7 extend.
8 The sheath 14 has a proximal end 30 and a tapered distal 9 end 32 (FIG. 3). The proximal end 30 of the sheath 14 is press fit into a slide switch 35 which extends upwardly 11 through an opening in the handle 12 and is accessible for user 12 manipulation tbereof. The sheath 14, barrel 16, and drive tube 13 18 extend through a central opening provided by the slide 14 switch 35. The slide switch 35 is pivotally mounted to a spring hoop 41 which, in turn, is pivotally mounted to the 16 handle 12.
17 As mounted within the handle 12 to the spring hoop 41, 18 the slide switch 35 is only capable of longitudinal movement.
19 More specifically, the slide switch 35 is-only capable of being "at rest" in either a forward position, which is 21 illustrated in FIG. 5, or a rearward position adjacent the 22 sheath stop 36. Preferably, ~ovement between the forward and 23 rearward positions is limited to about 0.435 inches. Thus, 24 rearwardly moving the slide switch 35 longitudinally slides the sheath 14 from a first position covering the cutting head 26 to a second position wherein the cutting head 20 extends out 27 of the sheath. Forwardly moving the slide switch 35 returns 28 the sheath 14 to the position covering the cutting head 20.
29 The remaining structural features of the third embodiment are generally identical to those described previously, and will 31 not be further described herein.
32 The mechanical morcellator 10 of the third embodiment 33 operates in the following manner. Following severance of the 34 tissue to be removed from the tissue to remain, the morcellator 10 is inserted via an existing laparoscope port.

In the preferred 4 embodiment the sheath 14, barrel 16, and drive tube 18 extend approximately 10.0 inches from the handle 12, allowing the 6 cutting head 20 to reach the tissue within the patient's body.
7 The morcellator 10 i8 not intended to be in operation during 8 insertion and the electrical and mechanical means described 9 previously prevent the unintentional operation thereof.
While the surgeon views the tissue to be removed and the 11 distal ends 32 and 44 of the sheath 14 and cutting head 20 via 12 a lapara~cope (not shown), the slide switch 35 is rearwardly 13 moved by the surgeon from the forward position in which the 14 sheath 14 covers the cutting head (FIG. 5) to the rearward position wherein the cutting head 20 extends out of the 16 sheath. Thereafter, the trigger 22 and trigger latch 38 are 17 manipulated as previously described with reference to the 18 operation of the second embodiment to actuate the motor 76 and 19 communicate suction to the cutting head 20. At any time during the procedure, the surgeon can cover the cutting head 21 20 with the sheath 14 by simply moving the slide switch 35 22 forwardly (i.e. toward the cutting head). This can be done 23 either while the cutting head 20 is rotating or, by releasing 24 the trigger 22 to disconnect the motor 76 from power, when the cutting head 20 is stationary.
26 When the procedure is complete, the surgeon merely 27 releases the trigger which opens the switch 81, turns off the 28 motor 76, and precludes communication of suction to the 29 cutting head 20. Thereafter, the slide switch 35 is returned to its initial or forwardmost position ~FIG. 5), allowing the 31 sheath 14 to extend over and cover the cutting head 20, and 32 the morcellator 10 i8 withdrawn from the port.
33 As should be clear from the foregoing embodiments of the 34 present invention, the comb~nation of the relatively moveable sheath 14, the trigqer latch 38, and the switch 81 cooperate 36 to provide a mechanical morcellator which prevents the . ~

7 While the preferred embodiments of the present invention 8 are shown and described herein, it is to be understood that 9 the present invention is not so limited but shall cover and include any and all modifications thereof which fall within 11 the purview of the invention as defined by the claims appended 12 hereto.

1 mechanical morcellator of the present invention is shown. The 2 third embodiment includes the handle 12, sheath 14, barrel 16, 3 drive tube 18, cutting head 20 (FIG. 3), and trigger 22. The 4 handle 12, which is preferably formed in two mating halves of polycarbonate or ABS plastic, provides a front aperture 24 6 through which the sheath 14, barrel 16, and drive tube 18 7 extend.
8 The sheath 14 has a proximal end 30 and a tapered distal 9 end 32 (FIG. 3). The proximal end 30 of the sheath 14 is press fit into a slide switch 35 which extends upwardly 11 through an opening in the handle 12 and is accessible for user 12 manipulation tbereof. The sheath 14, barrel 16, and drive tube 13 18 extend through a central opening provided by the slide 14 switch 35.
