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.

means connecting said jaws to said center slide for said anvils to move together when said handles are squeezed and for said anvils to move apart when the handles are released;

a cartridge with a supply of ligating clips; and

means for retracting all except the respectively leading clip located between said anvils, in direction rearwardly away from said anvils prior to movement of said anvils together,
