Ligating device
First Claim
1. A surgical ligator to locate and clamp a substantially inverted U-shaped clip about a tubular member to close off the tubular member, said ligator comprising a magazine housing containing a supply of said clips, said housing at its distal end terminating in a clip forming portion, said ligator having a clip forming handle and a clip feeding handle to be grasped by the hand of a surgeon in pliers-like fashion, said clip forming handle being pivotally secured to said magazine housing and having a clip forming end configured to cooperate with said clip forming portion of said magazine housing to clamp a clip about a tubular member, said clip forming handle being shiftable by the hand of a surgeon between an open unactuated position and an actuated closed clip-clamping position, said clip feeding handle being pivotally secured to said magazine housing, said clip feeding handle being shiftable by the same hand of a surgeon between an open unactuated position and a close actuated position, means operatively connected to said clip feeding handle to shift the forwardmost clip of said supply from said magazine housing to a position between said clip forming portion of said magazine housing and said clip forming end of said clip forming handle upon the shifting of said clip feeding handle from said actuated position to said unactuated position, and means to insure proper sequential movement of said handles.

Abstract
There is disclosed a ligating device which includes a magazine housing containing a supply of ligating clips. The device has two handles and when these handles are squeezed together they clamp a ligating clip about a vessel to be ligated. When the handles are released, a linkage between one of the handles are released, a linkage between one of the handles and the magazine, feeds a succeeding ligating clip into position for use. Thus, the feed of clips in the device is entirely independent of any effort on the part of the surgeon using the device.

9. A surgical ligator to locate and clamp a substantially inverted U-shaped clip about a tubular member to close off the tubular member, said ligator comprising a magazine housing containing a supply of clips, a clip clamping handle and a clip feeding handle, pivotally secured to said ligator, said housing at its distal end and said distal end of said clip forming handle each terminating in a forming portion, said clip forming handle being operative to clamp one of said clips between said forming portions upon actuation of said handles, and feed means for sequentially feeding said clips between said forming portions to be clamped, said feed means including a feed element operatively connected to said clip feeding handle and shiftable upon actuation of said clip feeding handle to a ready postion adjacent the next clip to be fed from said magazine, and sequentially upon release of said clip feeding handle to a feed position in which said next clip is positioned by said feed element between said forming portions to be clamped.
