A surgical instrument for stapling and cutting a blood vessel or other organic structure utilizes surgical staple clips. The surgical instrument includes an elongated tube or rod 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. In one version, 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 may also be included in the system. When the rod longitudinally moves with respect to the elongated tube or rod, the clip jaw sets clip the surgical staple clips onto the blood vessel or other organic structure. The handle for the surgical instrument includes a movable member coupled to a movable rod and a stationary grip member mounted to the elongated tube, within which moves the longitudinally movable rod. The movable handle member pivots towards and away from the stationary handle member. The movable member includes a tactile response surface which abuts a response wall on the stationary member. The surgical staple clip includes a clip face adapted to interface with the blood vessel or other organic structure.

Surgical instrument for stapling and cutting blood vessels and organic structures

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.
