Abstract

The surgical instrument for stapling and cutting a blood vessel or other organic structure utilizes surgical staple clips. The surgical instrument includes an elongated tube having a longitudinally movable rod disposed therein. A handle is mounted on the proximal end of the tube. The handle has a movable member which causes the movable rod to longitudinally shift positions in the tube. A pair of surgical staple clip-carrying jaw sets are pivotally mounted on a common lateral axis located at the distal end of the elongated tube. A scissor jaw set is disposed intermediate the pair of clip jaw sets and is also pivotally disposed on the same common lateral axis. The surgical instrument includes a laterally extending cam that is mounted on the distal end of the movable rod. The cam moves within cam follower channels defined in the clip jaw sets and the scissor jaw set. When the cam longitudinally moves based upon movement of the rod, the clip jaw sets first clip the blood vessel or other organic structure due to the clip-action cam follower channels. Thereafter, the scissor jaw set closes based upon the longitudinal movement of the cam in the cut-action cam follower channel.
