ABSTRACT:
A surgical clip for clamping of small blood vessels having arms integrally joined and terminating in a pair of flat jaws. The arms are formed of springy material and outwardly sprung. The first arm has a cam track on its outer edge which is divergently angled. A cam follower including a resilient rod is mounted cantilever-fashion on the second arm having at its end a cam follower member riding upon the cam track to bring the jaws into a desired degree of clamping force with a blood vessel. In the preferred embodiment the resilient rod is mounted in position to have a condition of maximum curvature when the cam follower is in its jaw-releasing position so that when the cam follower arm is flexed and then manually released the cam follower tends to move automatically to a clamping position. The cam track is preferably convexly curved and made up of a closely spaced series of transversely extending detent recesses.
