Abstract

A surgical clip, particularly adapted to produce necrosis in Fallopian tube tissue, consists of jaws hinged adjacent one end and a U-shaped spring which holds the jaws open in one position and exerts a closing pressure on the jaws in another position. The clip is particularly adapted to be applied to tube tissue, through a laparoscope designed to have a pair of slidable actuators one of which closes the clip jaws and assists in retaining the clip in proper location at the distal end of the laparoscope and the other actuator is adapted to position the Ushaped spring in the jaw closing position.

Claims

1. A surgical clip and actuator for occluding tubes in a living animal said clip comprising first and second jaw members;

means adjacent one end of each jaw member pivotally mounting the other ends of said jaw members for movement toward and away from each other;

a generally U-shaped spring member engaging remote surfaces of each jaw member and slidable from a first position on one side of the said pivotal mounting, to urge said jaw members into the open arrangement, to a second position on the other side of the said pivotal mounting, to urge said jaw members into the closed position; and

said actuator including a cradle for said clip and first and second manually operable rods;

said first rod adapted to contact a top surface of said first jaw member and to urge said jaw member toward said second jaw member against the urging of said U-shaped spring when said spring is in sAid first position; and

said second rod positioned to urge said U-shaped spring into said second position.

2. A surgical clip for occluding tubes in a living animal comprising first and second jaw members;

means adjacent one end of each jaw member pivotally mounting the other ends of said jaw members for movement toward and away from each other;

a generally U-shaped spring member engaging remote surfaces of each jaw member and slidable from a first position on one side of the said pivotal mounting, to urge said jaw members into the open arrangement, to a second position on the other side of the said pivotal mounting to urge said jaw members into the closed position.

3. An actuator for a surgical clip comprising an elongate tubular body portion, a clip receiving cradle having a bottom wall and an end wall extending longitudinally from one end of the tubular body, first and second manually operable rods mounted in said tubular body and for reciprocation relative thereto, said first rod having an actuating head positioned in a plane immediately above the cradle and reciprocal in said plane over said cradle, a first actuating member mounted at the opposite end of the first rod at the end of the tubular body remote from the cradle, said second rod having an actuating head aligned with said cradle and movable immediately over the bottom wall of the cradle, and a second actuating member mounted at the opposite end of the second rod at the end of the tubular body remote from the cradle.

4. A surgical clip as defined in claim 2 wherein the opposed surfaces of each jaw member are provided with a plurality of opposed interfitting tube gripping elements.

5. The invention defined in claim 4 wherein said opposed alternate interfitting elements comprises cooperating cones and conical bores.

6. The invention defined in claim 4 wherein said generally U-shaped spring member is of ribbon configuration and the remote faces of the jaw members are provided with elongated slots within which the ribbon-like U-shaped spring is adapted to slidably traverse.

7. The invention defined in claim 6 including turned in tip elements on said U-shaped spring and cooperating transverse slots in said grooves of each jaw member to secure the U-shaped spring when said spring is in the position to urge the jaw members into their closed position.

8. The invention defined in claim 3 wherein said tubular body includes a surgical microscope and a source of light therefor.

9. The invention defined in claim 8 wherein said light source includes a bundle of light transmitting fibers.

10. The invention defined in claim 9 wherein said light transmitting bundle of fibers are arranged in an oval configuration.
