Abstract
An endoscopic tissue retractor capable of being inserted through an endoscopic tube and subsequently capable of forming a T-shaped bar at its distal end. The legs of the 'T' may be aligned with the axis of the tissue retractor for insertion within an endoscopic tube and situated transversely to the longitudinal axis for actual use. In use, the legs extend to diametrically opposed sides of the longitudinal axis of the tissue retractor and are rotatable in a plane passing through the axis of the endoscopic tube. A transversely slidable locking mechanism is provided to lock the components of the tissue retractor in a desired position.
