Description
WO 95105129 ' PCT/US94109346 MEDICAL DEVICE WITH IMPROVED ACTUATING HANDLE
This invention relates to polypectomy snares and other actuated medical devices.
Backctround of the Invention There is a need for improved actuation for medical devices. One important example is the surgical snare handle. Snares are used to surgically remove polyps (pre-cancerous tissue growth in the colon and rectum), to remove esophageal carcinoma, and to perform nephrostomy.
A snare device is inserted through a working channel of an endoscope fitted with a fiber optic camera, the output of which is attached to a video monitor.
In the case of a polyp, a doctor manipulates the endoscope in the tract of the patient until a polyp is located. The end of the snare in the form of a wire loop is extended and positioned around the polyp, and at the doctor s request, an assistant, typically a nurse, retracts the snare to cause the loop to retract and resect the polyp. An electrical current, such as r-f, is passed through the Ioop to cauterize the polyp and prevent bleeding.
The same technique is employed for other physical features to be excised or cut by a snare.
The snare is controlled by a snare handle. It is desirable that a snare handle have great fidelity so that whatever resistance is experienced by the snare is felt through the handle by the operator. If the operator cannot feel what is happening at the snare end, the polyp or other tissue might be severed before the cautery current has been applied, causing bleeding and other harmful consequences.
It is desirable that the snare be capable of extending fully and of retracting into the sheath a ~~~.~~9~8 certain distance as a safety margin, for instance .75 inches. It is also desirable that the handle be constructed so that nurses with small hands can operate it.
Handles having good tactile feeling have long been available. These handles typically have one-to-one activation ratio in which the actuating element of the handle moves the same amount as the snare. Because the distance the snare must move is fairly large, these handles have been difficult to operate with one hand, especially for people with small hands. Attempts have been made to provide a handle which moves only a fraction of the distance of the snare travel. The presence of intervening parts, which may be subject to deformation under load, between the snare loop and the actuating member, however, has rendered the tactile sensitivity of these handles sub-optimal. Furthermore, these handles have also been complex, expensive to manufacture and have had other disadvantages.

In a preferred embodiment, pulley surface 26 defines a rigid, semi-circular track integral with actuating member 24 and has a cross section only slightly larger than cable 12 to prevent cable 12 from buckling under compressive force.
Pulley surface 26 may be located as shown in FIGS.
2 and 3 or may be located at another position on actuating member 24, such as the embodiment shown in FIG.
6, where pulley surface 26 corresponds with finger hole 37.
Pulley surface 26 may also be rotatable as shown in FIGS. 7 and 7a. In this embodiment, pulley 27 is _ g rotatably mounted on axle 29. Pulley surface 26 may be flat or indented to accommodate cable 12.
A biocompatible silicon type lubricant may be used ' to reduce friction on pulley surface 26 in embodiments of the invention employing both fixed and rotatable pulley ' surfaces.
The pulley advantage of pulley surface 26, which is in direct contact with cable 12, allows the operator to achieve the desired two to one activation ratio, while the absence of intervening parts provides the tactile feeling previously only available in handles with a one to one activation ratio.
Referring now to FIG. 2A, cable 12 passes through nose 16 of handle body 18 around pulley surface 26 on actuating member 24, and back to nose 16 where the end of cable 12 is fixed to nose 16. Cable 12 is confined throughout its entire pathway within medical device 10 to prevent columnar buckling. Preferably, cannulae 38 and 40 are used to confine cable 12 between nose 16 and actuating member 24. Cable 12 is connected, by soldering or any other method, to one end of cannula 38. This end is attached to body 18 by set screw 42 disposed in can 44 on nose 16. The other end of cannula 38 is telescopically disposed within actuating member 24.
Similarly, cannula 40 has one end attached to actuating member 24 and the other end telescopically disposed within aperture 46 in nose 16.
Referring now to FIG. 3, actuation of the snare handle causes cable 12 to move about pulley surface 26, through cannula 40 and out nose 16. Due to the pulley advantage of pulley surface 26, movement of actuating .
member 24 a given distance 62 results in translation of cable 12 twice the given distance 64. Similarly, when actuating member 24 is retracted, cable 12 retracts twice as far as the movement of actuating member 24 due to the pulley advantage of pulley surface 26. This two-fold . WO 95105129 g increase in the cable stroke relative to movement of actuating member 24 permits a nurse with small hands to operate the snare handle with one hand.
Cable 12 is preferably a stainless steel braided cable that is quite stiff and not prone to buckle under compression. Cable 12 could, however, be any other electrical conductive,~such as single strand wire, which is capable of withstanding both tensile and compressive forces, and may have rigid portions. The cable currently contemplated to be used by the invention has a diameter from 10 to 60 thousandths of an inch and more preferably from 30 to 40 thousandths, although other cable diameters may be acceptable.
Cannulae 38 and 40 are preferably stainless steel tubes which confine cable 12 and allow about five thousandths of an inch clearance between the inside wall of the tube and the cable. The cannula wall is preferably about two thousandths of an inch thick. The exterior of cannula 38 and 40 may be coated with an insulator such as nylon to prevent a person operating the medical device from being shocked. Alternatively, as shown in FIG. lA, guard 41 (a part of body 18 which extends outward from legs 30 to cover cannula 38) may be included for this same purpose.
Referring now to FIG. 2A, set screw 42 attaches cannula 38 to body 18 such that an electrical connection forms. If a connector is attached to the set screw, an electrical current, such as r-f, may be applied to cable 12, thereby allowing for electrical cauterization of a polyp by snare loop 20.
Sheath 14 has flared end 48 which is attached by compression cap 50 to side extension 52 of nose 16. Side extension 52 carries a plurality of threads 54 on an outer surface and has beveled front 60 which mates with flared end 48. Compression cap 50 is threaded onto side WO 95!05129 PCT/US94109346 extension 52 and traps flared end 48 against beveled front 60.
The inside of sheath 14 aligns with aperture 46 in ' nose 16 and is large enough that cannula 40 may be~
telescopically disposed in it, but must also be small enough to prevent cable 12 from buckling upon application of compressive force. Sheath 14 is preferably made of teflon or another lubricous flexible material which does not conduct electricity. Tip 22 of sheath 14 may be cut on any desired angle.
Referring now to FIG. 3, snare loop 20 is preferably attached to the distal end of cable 12 by crimp connector 58, however, another means of connection, such as soldering or brazing, may be used. It is desirable that this connection be capable of conducting electricity from cable 12 to snare loop 20.
Snare loop 20 is preferably stainless steel braided wire of a lesser diameter than cable 12, usually from 20 to 40 thousandths of an inch in diameter. Snare loop 20 should be flexible to withdraw into the end of sheath 14, and should be resilient and retain its shape when extended.
As shown in FIGS. 8-18, other types of working elements such as baskets 66-78, grasping forceps 80, right angle snare loop 82, or point type cauterization device 90 may be substituted for snare loop 20. Baskets 66-78 may have tips 84 of any desired length or shape, and the number of wires may vary, although usually four or six wires are used. As shown in FIG. 11, basket 68 may be designed to slide upon guide wire 86, or, as shown in FIG. 12, basket 68 may be designed to accommodate pulsed-dye laser fiber-optic probe 88. Grasping forceps 80 may have three prongs as shown in FIG. 17 or any other desired number of prongs. Point type cauterization device 90 may be any type of needle, wire or electrode.
The snare handle described above may also be useful in other areas of medicine, such as laparoscopic surgery, or as a syringe handle. It occasionally is necessary to pickup or deliver very small amounts of drugs such as Tpa. As shown in FIG. 19, when the medical device of the invention is used as a syringe, sheath 14 is reduced in size so that the inside diameter of sheath 14 is substantially identical to the diameter of cable 12. Preferably, the clearance between sheath 14 and cable 12 would be one to two thousandths of an inch. The working element in this embodiment of the invention is a device such as plug 92, which is disposed on the end of cable 12 such that a seal is formed between plug 92 and the inside of sheath 14. When the cable is withdrawn, this seal causes a suction which draws fluid into the end of sheath 12. Preferably, the length of cable 12 is adjusted so that plug 92 remains within sheath 14 regardless of the position of actuating member 24 .on body 18. The length of cable 12 must also be adjusted so that plug 92 will extend completely to tip 22 of sheath 14.
Plug 92 may be any type of material, such as rubber, which will cause a seal to form.
As shown in FIGs. 20 and 20a, the medical device of the invention could be used in conjunction with a single balloon or multi-balloon catheter 94 by inserting cable 12 and associated working element, preferably plug 92, through lumen 96. Balloons 98 are inflated by the introduction of fluid through lumens 100, 102 and 104 which may be of any desired shape. Lumens 100, 102, and 104 preferably run the length of balloon catheter 94, but do not intersect catheter end 22.
