Apparatus for clamping an organ during surgery
First Claim
1. A laparoscopic surgical apparatus comprising:
- a handle section;
a clamp formed by a top jaw and a bottom jaw to provide a pair of substantially parallel jaws, a laparoscopic section including an elongated cylindrical shaft having a proximal and a distal end, said proximal end being connected to said handle section and said distal end pivotally connected to said clamp, a clamp actuating assembly including a cable interconnecting said handle section and said clamp for actuating said clamp between an open position with said top jaw being displaced from said bottom jaw and a closed position state wherein said opposed parallel jaws in relatively closer positioned than when in said open position.

Abstract
This invention is a surgical clamp for the purpose of occluding the kidney or other organ and thereby obtaining a bloodless surgical field, while allowing the majority of the organ to remain normally perfused. Previous approaches are limited in ability to provide sufficient clamping force without damaging the oran. The invention comprises a first and second jaw, wherein the proximal ends of the two jaws, and the distal ends of the two jaws are connected by a strap, such that applying tension to the strap results in moving the relative positions of the jaws in a substantially parallel motion, which provide a clamping force to the organ. The jaws can be attached with a flexibly joint to a hollow shaft, such that a cable inside the shaft can be used to apply tension to the strap while maintaining the ability to pivot the jaws relative to the shaft.
