Surgical retractor and use in a thoracoscopic operation

摘要

The retractor has a splayable spatula (3) provided at a distal end of a gripping part (2), and a working channel for retaining an optic. The spatula is mounted at a distal end of a push rod provided in a pipe, where the push rod is moved relative to the gripping part. The spatula is splayed by a splaying plate when distance between the pipe and the push rod is reduced. A high elastic bar is clamped by the spatula and has a closed surface in a splayed condition such that force is transmitted to inner organs by the closed surface.
