ABSTRACT:
A surgical retractor for endoscopes and cystoscopes formed substantially entirely from resilient synthetic resinous material which in relatively unstressed condition forms a hook-like appendage at a distal end thereof, and which may be distorted to rectilinear configuration to fit within a channel in an endoscope barrel. The appendage may be of either endless or bifurcated configuration defining an enclosed area which is covered by a web-like membrane preventing the entry therebetween of any loose tissue which would otherwise be entrapped within the retractor when the same is withdrawn after use.
