Surgical instrument for clipping and cutting blood vessels and organic structures
First Claim
1. A surgical instrument for stapling with surgical clips and cutting a blood vessel or other organic structure comprising:
- an elongated tube having a proximal end and a distal end, said tube having a longitudinally movable rod disposed therein;
a handle mounted on said proximal end of said tube, said handle having a movable member coupled to said movable rod which longitudinally moves said rod with respect to said tube upon actuation of said movable member;
a pair of surgical staple clip carrying jaw sets, each clip jaw set having two jaw members which pivot about a common lateral axis located at said distal end of said elongated tube, each jaw member defining a clip channel at its jaw mouth, each one of said clip jaw sets of said pair of clip jaw sets being pivotally disposed at opposite ends of said common lateral axis;
a scissor jaw set pivotally disposed on said common lateral axis, said scissor jaw set having upper and lower, opposing scissor jaw members which pivot about said common lateral axis;
a laterally extending cam mounted on said distal end of said moveable rod;
each clip jaw set defining a clip-action cam follower channel and said scissor jaw set defining a cut-action cam follower channel, said laterally extending cam disposed in said cam follower channels and said follower channels shaped to initially close said clip jaw sets and then subsequently close said scissor jaw set and cut said blood vessel or other organic structure upon longitudinal movement of said laterally extending cam.

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.

16. A surgical instrument for stapling with surgical clips and cutting a blood vessel or other organic structure comprising:
-
an elongated tube having a proximal end and a distal end, said tube having a longitudinally movable rod disposed therein;
a handle mounted on said proximal end of said tube, said handle having a stationary grip piece and a compressible grip piece, said compressible grip piece coupled to said movable rod which longitudinally moves said rod and retracts said movable rod from said distal end of said tube upon compression of said compressible grip piece;

20. A method for surgically stapling and cutting a segment of a blood vessel or other organic structure in a body with an elongated surgical instrument having an elongated movable rod extending from an outboard, proximal position to a distal, surgical site in said body, said surgical instrument carrying two surgical staple clips at the distal end thereof, the method comprising the steps of:
-
axially retracting said rod in a single, operative stroke;
simultaneously clipping both sides of said segment of blood vessel or other organic structure with said two surgical staple clips during an initial portion of said singular operative stroke; and
subsequently cutting said segment of blood vessel or other organic structure during a subsequent portion of said singular operative stroke. - View Dependent Claims (21, 22, 23, 24, 28, 29, 30, 31)
