Abstract

A miniature surgical clip made of a single continuous length of spring wire for clamping blood vessels in brain surgery and the like. The clip includes a pair of operating members arranged at an acute angle and connected together at a common apex. The operating members are symmetrically formed and have inwardly bent legs which extend mutually inward in overlapping relation to form spaced parallel portions defining between them a lateral guideway. Each of the inwardly bent legs terminates in a 270.degree. exit loop having straight exiting portions which are captive in, and which extend through, the guideway parallel to one another to form cooperating jaws which are straight and parallel. The operating members are outwardly sprung with respect to one another for biasing the jaws resiliently into clamping engagement. In the preferred form of the invention the operating members have respective operating loops which are arranged perpendicularly to the plane of the clip and in axial alignment with one another for engagement by opposed points on a tweezer-type applicator which applies mutually inwardly directed force for temporary spreading the jaws for engagement of a blood vessel between them.
