ABSTRACT:
A retractor for use in laparoscopic surgery comprises a substantially rigid tubular outer member and a retractor member at least partially inserted in the tubular member for slidable motion in an axial direction relative thereto. The retractor member is provided with a distal end portion having limited flexibility which enables a bending of the distal end portion upon application of a bending force greater than a predetermined threshold. In addition, the distal end portion has a spring bias tending to return the distal end portion to a linear configuration upon relaxation of bending force below the threshold. A camming surface is provided on the tubular member at the distal end thereof for bending the distal end portion during a distally directed longitudinal stroke of the retractor member relative to the tubular member, whereby at least a terminal part of the distal end portion extends at an angle with respect to the tubular member.
