1. An artery clamp comprising a base, an elongated upright tubular member joined to said base, said member including an axially extending slot along a portion of its length, said slot opening into the interior of said member, an elongated rigid arm structure including an elongated mounting portion slidably received within said tubular member, and, joined to said mounting portion, an arm portion extending out through said slot and overlying said base, said mounting portion having an exterior transverse profile similar to but smaller in area than the interior transverse profile of said tubular member, an angular change in position of said arm portion with respect to the base being thereby effective to lock the arm structure against movement along said member through axial misalignment and consequent frictional engagement between said mounting portion and member, said arm structure further including means for releasing the same from a locked condition, said means including a release arm overlying said arm portion, joined to cam means pivotally mounted on said mounting portion within said member whereby, with the arm structure in a locked condition, movement of said release arm away from the base produces substantial axial alignment of said mounting portion and said member through engagement of the cam means with the tubular member, releasing them from frictional engagement, and a pressure pad joined to said arm structure adjacent the other end thereof.
