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.
