Abstract

An intestinal occluding clamp including first and second clamping members with jaws, a biasing spring, a clamp housing, a clamp base and a clamp cap. The clamp housing has a housing cavity formed at one end thereof and a first clamping member is connected to and projects away from the housing cavity. The biasing spring is disposed within the cavity and circumferentially about the base post. The clamp cap and biasing spring are retractably mounted within the housing cavity and provide a spring-loaded, push-button housing for simple and reliable operation. Take-up clearances within the housing are provided such that when the cap is fully depressed downwardly with one's thumb, the distal ends of the jaws first move apart until the clamp is in locked-open position with no spring resistance against the surgeon's thumb, and when the clamp is released, the clamping members move towards each other during spring-biased forced closing movement, and finally the jaws become substantially parallel with the tubular structure, interposed therebetween. Another aspect of the present invention is an intestinal occluding clamp with first and second corrugated surfaces having anti-slip grooves which facilitate sliding of an intestine between the open clamping members with minimal degree of resistance or reacting force and, provides essentially high resistance to movement of clamped vessel's out from between the substantially parallel, closed clamping members.
