Abstract
Abstract A surgical retractor stay (9) has a tissue holding hook (15) affixed to the elastic hollow tubing member (12) of the stay by a retaining member (11) having a body (14) in which the hook shank is embedded with the sharp end of the hook extending from one end of the body. A stud (16) with a tapered knob (17) on its outer end extends outwardly from the other end of the retaining member body, the size and configuration of the knob and stud being such as to be tightly retained within an end portion of the hollow tubing (12) stretchingly installed thereover. A surgical tube connector (24) for joining a pair of hollow elastic surgical tube members (12) having an elongated stud (25) with tapered knobs (27) at each end in which the stud and knobs are dimensioned for tight fitting containment within the end portions of the hollow tube members stretchingly installed thereover.
