  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • [0121]
    Embodiments of the general uterine manipulator and associated system provide a multipurpose manipulator that may be used for a variety of procedures by interchanging particular fittings of the manipulator. With particular reference to FIGS. 1 a to 2, each embodiment of the general uterine manipulator 10 (hereinafter referred to in general as “manipulator 10”) is based on or incorporates an elongated hollow tube 12 defining an internal passage 14. Tube 12 has opposite first and second ends 16 and 18 and a smooth continuous outer surface 20 of constant outer diameter. A first internal screw thread T1 is formed at the first end 16 and a second internal screw thread T2 is formed at the second end 18.
  • [0122]
    The versatility of the manipulator 10 and associated system arises from the ability to connect with a number of different fittings depending on the specific application at hand. FIGS. 1 a and 1 b illustrate a first fitting in the form of tail screw 22 and a second fitting in the form of a cervical screw 24. An inner manipulator rod 26 is also illustrated in FIGS. 1 a and 1 b which extends through the first fitting 22, tube 12, and second fitting 24.
  • [0123]
    One form of the first fitting 22 is shown in greater detail in FIGS. 3 to 5. In this embodiment the first fitting 22 comprises a threaded portion 28; an integral body portion 30; and, an internal axial hole 32. Threaded portion 28 is configured to engage screw thread T1 and is provided with a transverse slot 34 terminating prior to the body portion 30. Slot 34 in effect divides the threaded portion 28 into opposed clamp shells 36 a and 36 b (hereinafter referred to in general as “clamp shells 36”). Body portion 30 is in the general form of a cylinder with two flats 38 a and 38 b on opposed sides that assist in gripping of the fitting 22. Axial hole 32 is of constant diameter for the length of the fitting 22 except for a counter sink 40 at a distal end of fitting 22.
  • [0124]
    Threaded portion 28 is slightly flared outwardly so as it is screwed into screw thread T1 at end 16, the clamp shells 36 move toward each other. When an inner manipulator rod 26 is used in the manipulator 10 this results in a clamping action on the rod providing resistance to movement of the rod 26 so as to hold it at a desired rotational and translational position. Unscrewing of the portion 28 releases or reduces this resistance to enable adjustment of the position and orientation of the rod 26. Thus the first fitting can be considered in this embodiment as incorporating or comprising a resistance mechanism which substantially maintains the position of the rod 26 until moved or adjusted by a surgeon or other user.
  • [0125]
    FIGS. 6 to 8 depict an alternate form of the first fitting denoted as 22′. Features of the fitting 22′ which are of the same or similar configuration or function as those of fitting 22 are denoted with the same reference numbers but with the addition of the prime (′) symbol. Fitting 22′ comprises a threaded portion 28′, body 30′, an inner axial hole 32′ with counter sink 40′ at a distal end, and opposed flats 38a and 38b formed on body portion 30′. Fitting 22′ differs from fitting 22 by the omission of slot 34, the inclusion of a hydrotubation port 42, and a re-configuring of the axial hole 32′. With particular reference to FIG. 7 it can be seen that the axial hole 32′ has a first length 44 and a contiguous second length 46. The first length 44 extends from the threaded portion 28′ for a majority of the axial length of fitting 22′. The second length 46 extends between and joins the counter sink 40′ to the first length 44. The inner diameter of the first length 44 is greater than the inner diameter of second length 46′. Further, the inner diameter of second length 46 is dimensioned to be slightly greater than an outer diameter of the inner manipulator rod 26 forming a close fit but enabling the rod 26 to pass through the axial hole 32′.
  • [0126]
    Hydrotubation port 42 is formed in the body 30′ at a location where it communicates with the first length 44. The thread on threaded portion 28′ is arranged to engage with the thread T1 at end 16. In the event that for example the manipulator 10 is being used in a gynaecological application and it is desired to inject a liquid such as a dye to assist in the visualisation of tissue the dye may be injected through the hydrotubation port 42. The dye then flows through the internal passage 14 and from an opposite end of second fitting 24 attached to end 18. In this regard in the event that manipulator rod 26 is in use, a clearance exists between second fitting 24 and an outer surface of rod 26 to allow the flow of dye or other fluid. Further, the close fitting between the rod 26 and second length 46 of axial hole 32′ substantially prevents any back leakage of the dye. Alternately and/or in addition if desired, a rubber grommet seal (not shown) may be provided in the second length 46 to further minimize back leakage of dye or other liquid injected through the hydrotubation port 42.
  • [0127]
    As the fitting 22′ does not have the clamping shells 36 of fitting 22 it is unable to clamp inner manipulation rod 26. However in embodiments of the manipulator 10, the inner manipulator rod 26 can be bent to varying degrees intermediate of its length so that the rod 26 bears against an inside surface of tube 12 to provide resistance to both axial and rotational motion when fitting 22′ is used. This still allows the rod 26 to substantially maintain its position until moved or adjusted manipulated by a surgeon or other user. Thus the intermediate bend in the rod 26 can be equated with or considered to be another or alternate form of resistance mechanism which substantially maintains the position of the rod 26 until moved or adjusted by a surgeon or other user.
  • [0128]
    The second fitting 24 of FIGS. 1 a and 1 b is shown in greater detail in FIGS. 9 a, 9 b and 9 c. The fitting 24 comprises a threaded portion 48 configured to engage thread T2, and an integral body portion 50. Body portion 50 is of a frusto-conical shape with a decreasing outer diameter in a taper direction D being away from threaded portion 48. A coarse screw thread 52 is formed about the conically shaped body portion 50. The crest of thread 52 has a flattened surface orientated so that a line 53 on the surface of the crest is inclined parallel with a central axis 55 of second portion 24. An axial through hole 57 is also formed through second portion 24. This allows for the passage of the inner manipulator rod 26 and/or other instruments as well as fluids including saline, dye, and air. In this embodiment of the manipulator 10, second fitting 24 is a cervical screw which is configured to screw into the cervix forming an attachment point as well as a seal.
  • [0129]
    However, alternate forms of second fittings may be incorporated in the manipulator 10. FIGS. 10 a-10 d illustrate an alternate second fitting 24 a. Fitting 24 a is in the form of a hollow probe having a threaded portion 48 a and a body portion 50 a. Threaded portion 48 a has a thread configured to engage with thread T2. Body portion 50 a is in the form of a tubular member which is open at its distal end 56 and is closed at an end 58 near threaded portion 48 a to define or otherwise form a cavity 60. Distal end 56 is formed with a chamfer or bevel 62 to assist in insertion of the fitting 24 a into a body cavity such as a vagina or rectum. Fitting 24 a may be used for example during a hysterectomy to maintain pneumoperitoneum after removal of the uterus. The cavity 60 also allows for collection of pelvic tissue and specimens from the abdominal and pelvic cavities. A lumen (i.e. through hole) 64 may be formed axially through a circumferential wall 66 of the body 50 a. In one embodiment the lumen 64 may have an internal diameter of approximately 6 mm to enable the receipt of a 4 mm telescope to enable illumination and visualization of tissue in cavities. For example this may be used in pelvic floor operations where the vagina and rectum septum need to be dissected out. This reduces the possibility of a recto-vaginal fistula occurring.
  • [0130]
    It is envisaged that the fitting 24 a may be made in a variety of different sizes and in particular different diameters. For example 40 mm outer diameter, 30 mm outer diameter, and 20 mm outer diameter.
  • [0131]
    FIG. 11 illustrates one form of a forceps holder 70 that may be incorporated in an embodiment of manipulator 10. The forceps holder 70 is configured to seat on the elongated hollow tube 12 and releasably lock at a desired location along the tube 12. Forceps holder 70 comprises a first component 72 that is able to slide over and along tube 12 and is provided with detents 74 for gripping a handle of the forceps. Two detents 74 are shown on opposite sides of a central boss 76. However in other configurations alternate numbers of detent 74 may be provided. The boss 76 is provided with a screw thread 78 extending from a cross piece 80 which contains the detent 74. Extending axially from the thread portion 78 is a split collar 82. The forceps holder 70 also includes a locking nut 84 that is able to screw onto the threaded portion 78 over the split collar 82 and act to clamp the collar 82 onto an outer surface of the tube 12 thereby releasably locking the holder 70 at an outside location along the tube 12. In one example, the forceps holder 70 may be used to hold valsellum forceps which in turn holds the manipulator 10 to the cervix making the manipulator self retaining.
  • [0132]
    With reference to FIGS. 12-14 b, the manipulator 10 may also support a cervical funnel 90 and a plug 92. The cervical funnel 90 is formed as a unitary device comprising a tube 94 of constant inner and outer diameter and an integral conical portion 96 which increases in outer diameter in a direction away from first end 16 of tube 12. The conical portion is provided with a lip 98 that extends about a part of the circumference of conical portion 96 and is flared in a radial outward direction.
  • [0133]
    Plug 92 sits on the outside of funnel 90 and when used in gynaecological procedures forms a plug in the vagina. With reference to FIG. 12, it can be seen that the forceps holder 70 may also act as a positioning device for the funnel 90.
  • [0134]
    FIGS. 13 a and 13 b depict in greater detail the cervical funnel 90 incorporated in the manipulator 10 shown in FIG. 12. The lip 98 is flared outwardly by an angle θ of approximately 130°. In this embodiment the outermost edge of the lip 98 extends for an arc a of approximately 115° about the conical portion 96. An inside diameter of the tube 94 is arranged to be slightly greater than the outer diameter of the tube 12 to enable the cervical funnel 90 to be rotatably and linearly moveable with respect to the tube 12.
  • [0135]
    FIGS. 14 a and 14 b depict in greater detail the vaginal plug 92 shown previously in FIG. 12. The plug 92 has a main body 100 formed of a constant outer diameter and a contiguous distal end portion 102 of progressively reducing outer diameter tapering to the distal end 104 of the plug 92. When the plug 92 is used with the manipulator 10, it is orientated so that the distal end portion 102 is directed toward the second fitting 24. An interior surface 106 of the plug 92 has a first portion 108 of constant inner diameter, and a contiguous second portion 110 of progressively increasing outer diameter. More particularly, the surface of the portion 110 is arranged to seat an exterior surface of the conical portion 96 of cervical funnel 90. Thus the increase in inner diameter of the surface of portion 110 is substantially the same as the angle of increasing diameter of the outer surface of conical portion 96.
  • [0136]
    FIG. 15 depicts an optional handle 120 incorporated in embodiments of the manipulator 10. The handle 120 comprises a grip 122 and a contiguous extension 124. The extension 124 is provided with a through hole 126 and a screw thread 128. The screw thread 128 extends from approximately the location of the hole 126 to an end 130 of the handle 120. The through hole 126 is dimensioned to enable the tube 12 to pass there through either with a slight interference fit or a small clearance. Thus the handle 120 extends perpendicular to the tube 12. The screw thread 130 is configured to enable coupling with a nut such as a second locking nut 84. The locking nut when tightened on screw thread 128 can then act to clamp the handle 120 to the tube 12. The handle 120 can be applied to any portion of the tube 12 between the end fittings 22 and 24 which is not otherwise covered by other components such as the cervical funnel 90.
  • [0137]
    From the above description it will be recognised that dependant on the application at hand the manipulator may take many different forms owing the interchangability of first and second fittings and the ability to use additional components such as the rod 26, the forceps holder 70, cervical funnel 90 and the plug 92. It is envisaged that a general uterine manipulator system or kit may be provided to surgeons and doctors composed of all or at least a selection of the first and second fitting; together with other components such as the rod 26, forceps holder 70, cervical funnel 90 and the plug 92. In this way the surgeon or doctor will always have at hand various components to enable the performance of many different procedures.
  • [0138]
    FIGS. 16 a-16 d illustrate a further form of a second fitting 24 b which primarily differs from the second fitting 24 a by the inclusion of an illumination device 140. Features of the fitting 24 b that have the same structure or function as the fitting 24 a are designated with the same reference numbers. In this embodiment the illumination device 140 is in the form of a ring 142 fitted to or otherwise supported at the distal end 56 of fitting 24 b. The illumination device 140 enables light to be emitted from the distal end 56. In one form the ring 140 is a ring of material embedded with one or more light emitting diodes (LEDs) 124. In this embodiment ring 142 may be made from a transparent acrylic resin. Power to the LEDs 144 is provided via a cable 146 that extends through the lumen 64. In the embodiment the lumen 64 may nevertheless be configured to also receive a telescope to enable visualization of the body cavity into which the fitting 24 b is inserted. In a variation of the illumination device 140, the ring 142 itself comprises a light guide that receives light from an optical fiber that passes through the lumen 64. Light transmitted through the optical fiber enters and travels about the ring 142 thus enabling the emission of light from the distal end 56.
  • [0139]
    FIGS. 17 a-17 c depict a cervical funnel 90 a which differs from the cervical funnel 90 by the provision of a light emitting device 140 a enabling the emission of light form distal end 99 and more particularly from the 98 of the funnel 90 a. The funnel 90 a has essentially the same physical structure as a funnel 90 and accordingly includes a first conical portion 96 and integrally formed tube 94. The lip 98 extends partly about an opening 101 formed at the distal end 99. The illumination device 140 a comprises an arcuate transparent body 142 a which may for example be made from of a transparent acrylic resin. Coupled to the body 142 a is an optical fiber 146 which is arranged to transmit light from a source to the body 142 a. The body 142 a has a configuration enabling it to be attached to the lip 98 in a manner so as to form a substantially continuous surface of the lip 98. The optical fiber 146 extends can through a channel or hole 148 formed in the funnel 90 a. In one embodiment, a channel or groove can be cut in the exterior surface of the body 90 a in which the optical fibre 146 is laid. Thereafter the groove can be filled with a resinous material and smoothed, effectively encapsulating the fiber 146 in the funnel 90 a. A coupling 148 at the end of the optical fiber 146 enables coupling with a light source or another optical fiber which carries light from the light source. In a variation to the illumination device 140 a, the body 142 a may have embedded therein one or more LEDs which when provided with electric current either: emit light directly from the body 142 a; or alternatively transmit light into the body 122 a from which it is emitted. In the event that the body 122 a carries one or more LEDs, then the optical fiber 126 is replaced with a wire or cable to provide electrical power to the LEDs.
  • [0140]
    FIG. 18 illustrates a manipulator 10 similar to that shown in FIG. 12 but with a modified cervical funnel 90 b and a motor 150 arranged to rotate the cervical funnel 90 b on, and relative to, the tube 12. The motor 150 is held within a housing 152 which is supported on a bracket 154. The bracket 154 is a squared U shaped configuration with opposed arms. The motor 150 is attached to one of the arms and a clamp 155 attached to the other arm. The clamp 155 can be operated to selectively grip and release the tube 12. When the clamp 155 is tightened it grips the tube 12 preventing axial or rotational motion of the tube 12.
  • [0141]
    The cervical funnel 90 b is provided with a wave like outer surface profile on its tube 94 as depicted most clearly in FIG. 19. Successive troughs 156 and peaks 158 of the wave like profile act as rounded gear teeth about the periphery of tube 94 b. These engage with a complementary shaped annular gear 160 driven by the motor 150. When the motor 150 is energized it rotates the gear wheel 160 and, due to its engagement with the outer surface of the tube 94 b, causes the funnel 90 b to rotate about and on the tube 12. Due to the manner of engagement of the motor 150 with the outer surface of the tube 94, the funnel 90 b can be slid linearly along the tube 12 while maintaining engagement with the motor 150. The bracket 154 is attached to an arm 162 that in turn can be clamped on to a stable support such as an operating table. A foot controlled switch 164 communicates with the motor 150 via a cord 166. A surgeon is able to operate the motor 150 by the foot operated switch 164. The motor may be in the forms of a bi-directional stepper motor and the switch arranged to control the direction of rotation. The illuminating device 120 a depicted in FIGS. 17 a-17 c may also be incorporated with the funnel 90 b.
  • [0142]
    FIGS. 20 a-20 c illustrate variations of a medical instrument that may be used with the manipulator 10. In FIG. 20 the medical instrument 170 comprises in effect the second fitting 24 a or 24 b formed back to back and integrally with the cervical funnel 90 or 90 a. The second fittings 24 a, 24 b differs slightly from those previously described in that they does not comprise a thread portion 48 but rather have a through hole at their proximal end 172 that communicates with the tube 94. Instrument 170 may be considered as comprising a body 174 provided with opposite first and second end portions 176 and 178. First end portion 176 has a first opening 180 and the second end portion 178 has a second opening 182. A throughway 184, constitute by the tube 94 extends between the first and second openings 180 and 182 and is arranged to enable the body 174 to be supported on a shaft such as the tube 12. With reference to FIG. 1 a, if the end of the manipulator 10 provided with the cervical screw 24 is taken is the leading end, then the instrument 170 can be supported on the tube 12 with either of the first and second end portions 176, 178 at the leading end of the manipulator 10. Whichever of the end portions 176 or 178 is at the leading end will be inserted into the body cavity during a medical procedure.
  • [0143]
    In the embodiment in FIG. 20, it can be readily seen that the end portions 176 and 178 differ in one or more of their shape, size and configuration. In particular in FIG. 20, the end portions 176 and 178 differ in at least their shape and configuration. End portion 176 has an outer diameter D1 measured in a plane of the opening 180 while the end portion 178 has an outer diameter D2 measured in a plane containing opening 162. In this embodiment D1 may equal D2 or alternatively D1 and D2 may be different.
  • [0144]
    FIG. 21 illustrates an alternate form of medical instrument denoted as 170 a comprising an opposite first and second end portions 176 a and 178 a respectively joined by an integral tube 94. Each of the portions 176 a and 178 a is of the general configuration of the portion 178 described in FIG. 20 but with different outer diameters D1 and D2. In particular in this embodiment D1 is less than D2. Instrument 170 a would be used in substantially the same manner as the second fitting 24 a or 24 b. However having the two end portions of different diameters D1 and D2 allows a medical specialist to simply use the end of instrument 170 a which is dimensioned for the best suit the body cavity into which it is to be inserted.
  • [0145]
    FIG. 22 illustrates a form of the medical instrument 170 b in which the first and second end portions 176 b and 178 b are both of the same general frusto conical configuration as the first end portion 176 in FIG. 20. The difference between the end portion 176 b and 178 b being their respective outer diameters D1 and D2. In this specific embodiment D1 is greater than D2. When the instrument 170 b is used with the manipulator 10 a medical specialist orientates the instrument 170 b with the end portion 176 b or 178 b at the leading end determined on the basis of the best match of outer diameter D1 or D2 to the vagina in to which it is to be inserted.
  • [0146]
    FIGS. 23 a-23 d illustrate a further variations to the cervical funnel 90 c. The funnel 90 c is of the same general shape and configuration and works in the same way as funnel 90, but differs by the provision of a through hole 190 in the lip 98. The through hole 190 is provided mid way along the arc of the lip 98. Optionally the funnel 98 may also comprise an illumination device 192. In this embodiment the illumination device 192 is in the form of an annular light guide coupled to an optical fiber. The annular light guide 192 surrounds the through hole 190. When the optical fiber is coupled to a light source the light is guided by the fiber 194 to the annular light guide and illuminates the annular light guide 192 providing a ring of light about the hole 190. The annular light guide 192 can be in the form a transparent acrylic resin ring. The optical fiber 194 can be embedded/encapsulated in a groove formed along the cervical funnel 90 d.
  • [0147]
    The hole 190 is dimensioned to receive the tip of an electrical cautery probe. During say a hysterectomy the probe is inserted into the hole 190. It is believed that the hole 190 will ordinarily be easily visible or locatable by a surgeon. However the provision of the illumination device 192 will assist in visually locating the hole 190. The electrical cautery probe is inserted through the vagina wall (which is being lifted by the lip 98) and into the hole 190. By applying electric current and rotating the funnel 90 d a very clean and precise circumcision can be made of the vaginal wall to separate it from the cervix.
  • [0148]
    The through hole 190 may also of course be incorporated in every other form of cervical funnel described hereinbefore. As can the annular light guide 192.
  • [0149]
    Now that an embodiment of the invention has been described in detail it will be apparent to those skilled in the relevant arts that numerous modifications and variations may be made without departing from the basic inventive concepts. For example, in one embodiment, the hydrotubation port 42 is illustrated and described as being formed on the first fitting 22. However in an alternate embodiment, a hydrotubation port may be formed on the tube 12 at a location near first end 16 but beyond the screw thread T1. In one embodiment, the first and second fittings 22, 24 may be formed from a plastics material so as to be disposable after a single use while the elongated hollow tube 12 may be made from surgical grade stainless steel so as to be reusable. All such modifications and variations together with others that would be obvious to persons of ordinary skill in the art are deemed to be within the scope of the present invention the nature of which is to be determined from the above description and the appended claims.
