Abstract
A wound retractor device comprises a distal member for insertion into a wound opening, a proximal member for location externally of the wound opening, a connecting member extending at least between the distal member and the proximal member. At least part of the connecting member is movable relative to the proximal member to shorten the length of the connecting member located between the distal member and the proximal member and thereby retract laterally the sides of the wound opening. At least part of the connecting member is movable relative to the proximal member by a guide slot through which the connecting member changes its direction to substantially perpendicular to the longitudinal axis of the wound retractor device.
