Abstract

A ligator device has handles which are linked to a center slide to make the same move rearwardly when the handles are squeezed together. A pair of jaws surround the front of the slide top and bottom and are connected to it so as to open when the handles are released and close when the handles are squeezed. The forward ends of the jaws carry anvils which, when closed, squeeze ligating clips shut which are supplied from a magazine.

Claims

1. A ligator device, comprising:

a pair of handles;

a longitudinally movable center slide having a lengthwise slot, which center slide is linked to said handles so as to move rearward when the handles are squeezed together;

a first jaw member having a slot which is angled crosswise of such first jaw member and having an anvil on a front end of the first jaw member, which first jaw member is slidably connected through such slot to a front portion of the center slide;

a second jaw member having a slot which is angled crosswise of the second jaw member in an opposite direction to the slot in the first jaw member and having an anvil on a front end of the second jaw member, which second jaw member is slidably connected through the slot of a front portion of the center slide;

connecting means for pivotally interconnecting the first and second jaw members to the center slide through the lengthwise slot on the center slide, which interconnecting means can slide along the length of the lengthwise slot; and

actuation means connecting the center slide in sliding cooperative engagement to the slot on the first jaw member and in sliding cooperative engagement to the slot on the second jaw member for moving the anvils of the first and second jaw members together when the handles are squeezed and for moving the anvils of the first and second jaw members apart when the handles are released.

2. A ligator device as defined in claim 1, wherein at least said anvils are of metal and at least some other mentioned parts are of synthetic plastic material.

3. A ligator device as defined in claim 1 wherein the connecting means comprises a pivot pin pivotally connected to the first jaw member and second jaw member and slidingly received in the lengthwise slot on the center slide.

4. A ligator device as defined in claim 1 wherein the actuation means comprises a pivot pin attached to the front portion of the center slide, which pivot pin slidingly engages the slot on the first jaw member and slidingly engages the slot on the second jaw member.
