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 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. A surgical staple clip includes a clip face adapted to interface with the blood vessel or other organic structure. The clip face has planar facial segments and a longitudinal center channel. The longitudinal center channel has a triangular cross-section. The clip face includes terminal planar facial segments which further define X-shaped channels with vertices coextensive with the longitudinal center channel.

Claims

1. A surgical staple clip for closure of a blood vessel or other organic structure comprising a clip body having a clip face adapted to interface with said blood vessel or other organic structure, said clip face having planar facial segments and a longitudinal center channel with a triangle cross-section there through, a terminal planar facial segment defines an X-shaped channel with a vertex co-extensive with said longitudinal center channel, said X-shaped channel having a triangular cross-section.

2. A surgical staple clip as claimed in claim 1 including two X-shaped channels, with vertices co-extensive with said longitudinal center channel, on each terminal planar facial segment.

3. A surgical staple clip as claimed in claim 2 wherein said clip face has a chamfer along its outer, opposing edges.

4. A surgical staple clip as claimed in claim 3 wherein said terminal planar facial segments are disposed at opposing ends of said clip face and said clip face includes intermediate planar facial segments and a medial bend segment.
