Abstract
Abstract A surgical clamp for the clamping of small blood vessels is formed of a piece of spring material and has two jaw sections urged against each other by the spring action of the material. The jaw sections include opposing parts which progressively increase in resiliency in opposite directions so that the total clamping force is essentially constant along the length of the jaw.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
169 words
A surgical clamp for vessels, said clamp comprising a single strip of resilient spring material formed to have an arched section at a rear end thereof and first and second jaw-forming sections extending forwardly of said arched section, said first jaw-forming section comprising a first portion of said strip which extends forwardly to a forward end of said first jaw-forming section and terminates at such forward end, said second jaw-forming section comprising a second portion of said strip which extends forwardly to a forward end of said second jaw-forming section and then reverses direction to define a third portion of said strip extending rearwardly adjacent said first portion, said third portion terminating at a location rearwardly of said forward end of said first jaw-forming section, said second portion being longer than said first portion, the first and third portions being resiliently separable to receive therebetween a vessel to be clamped whereby a substantially uniform clamping force is obtained over the entire coincident lengths of the first and third portions.
Claim 2
Dependent Claim
169 words
A surgical clamp for vessels, said clamp comprising a single strip of resilient spring material formed to have an arched section at a rear end thereof and first and second jaw-forming sections extending forwardly of said arched section, said first jaw-forming section comprising a first portion of said strip which extends forwardly to a forward end of said first jaw-forming section and terminates at such forward end, said second jaw-forming section comprising a second portion of said strip which extends forwardly to a forward end of said second jaw-forming section and then reverses direction to define a third portion of said strip extending rearwardly adjacent said first portion, said third portion terminating at a location rearwardly of said forward end of said first jaw-forming section, said second portion being longer than said first portion, the first and third portions being resiliently separable to receive therebetween a vessel to be clamped whereby a substantially uniform clamping force is obtained over the entire coincident lengths of the first and third portions.
Claim 3
Dependent Claim
43 words
A surgical clamp according to claim 1, wherein said arched section defines a convexity which faces forwardly, said arched section having first and second ends which are joined to rear ends of said first and second portions respectively, to form manual gripping handles.
