A wound protector retractor 1 comprises an inner O-ring 10 for insertion through a wound opening and a connecting sleeve 11 extending between the O-ring and outer mounting means 20, 21. The outer means 20, 21 are provided by rings 20, 21 between which the sleeve is led. The rings 20, 21 are rotated relative to each other and the inner ring 10 to form a centralised lumen 12 of reduced cross section and to shorten the axial extent of the sleeve. A wound is both retracted and protected. <IMAGE> |
