Patent Images
1. A suture cartridge for use in a surgical suture applicator which includes:
- a pair of lever members pivoted together and having jaw elements thereon;
a needle slidably carried on one of said jaw elements for movement between a retracted position within saiD one jaw element and an extended position protruding therefrom;
means on the end of said needle for grasping a length of suture extended across the path of said movement; and
means on one of said lever members for driving said needle from said retracted position to said extended position in response to closing movement of said lever member;
said suture supply cartridge comprising;
a casing;
a bobbin adapted to carry a length of suture wound thereon;
mounting means in said casing rotatably receiving said bobbin;
a forward extension on said casing forming a passageway for a length of suture unwound from said bobbin;
a forward extension on said casing forming a passageway for a length of suture unwound from said bobbin;
a transverse opening through said forward extension adapted for registry with said path of needle movement;
suture gripping means on said forward extension outboard of said transverse opening;
means on said casing for releasable securing said casing to said one jaw element of the suture applicator; and
a flesh-gripping surface on said forward extension around said transverse opening.

Abstract
A cartridge for a suturing clamp in which the flesh is clamped by a pair of jaws and further movement of the clamp actuator handle drives a needle, carrying a length of suture with it, through the flesh. A cartridge, which rotatably carries a bobbin with suture, is releasably gripped on one of the jaws, and a narrow slot at the forward end grips a length of suture to hold it across the path of the needle. When the cartridge is in place on the clamp, a roughened undersurface forms one of the flesh gripping surfaces, and a cover on the cartridge is held against a surface of the clamp jaw so that it cannot fall from the cartridge.
