1. A surgical apparatus comprising:
- (a) a frame and at least one actuating handle movably mounted with respect to the frame;
(b) an elongated section having a proximal end connected to the frame;
(c) flexible opposing jaws positioned at the distal end of the elongated section;
(d) a cam member having a proximal end which extends into the frame and a distal end which at least partially surrounds the flexible opposing jaws, the cam member being movably positioned within the elongated section between a proximal position and a distal position wherein the flexible opposing jaws are cammed into closure;
(e) a pusher member having a proximal end which extends into the frame and a distal end, the pusher member being movably positioned within the elongated section between a proximal position and a distal position whereby a clip is moved within the flexible opposing jaws; and
(f) a spring positioned within the frame and abutting the cam member and the pusher member, the spring biasing the cam member proximally and the pusher member distally.

Abstract
An apparatus for applying surgical clips through an endoscopic tube includes an endoscopic portion housing a jaw blade, a pusher bar for feeding clips one at a time to the jaws, a channel bar for camming the jaw blades into closed position, and an array of surgical clips. The body of the apparatus comprises a frame housing an actuating mechanism and a transmission mechanism for transferring movement to the pusher bar and channel. The endoscopic portion is rotatable relative Go the frame. In one embodiment the apparatus is a single disposable unit. In an alternative embodiment the endoscopic portion is detachable and disposable whereas the non-endoscopic body portion is reusable.
