Abstract
An endoscopic stitching device is provided including a handle assembly supporting a manually operated suture needle loading assembly; a tool assembly operatively supported on and connected to the handle assembly; a suture needle operatively associated with the tool assembly, wherein the tool assembly includes a pair of juxtaposed jaws pivotally associated with one another; and an actuation cable extending between the handle assembly and the tool assembly, wherein axial displacement of the actuation shaft results in opening and closing of the jaws and rotation of the actuation cable results in selective retention of the suture needle in the jaws. A proximal end of the actuation cable is connected to the suture needle loading assembly such that actuation of the suture needle loading assembly imparts rotation to the actuation cable to selectively engage the suture needle in one of the jaws.
