WIPO Patent Application WO/2013/003613
Kind Code:
A3
Abstract:
An intracorporeal surgical tissue retractor is provided having an anchor selectively deployable in a first tissue not to be retracted and a grasper selectively deployable on a second tissue to be retracted. A longitudinally selectively movable support is threadable through the anchor and attached at a substantially distal end of the movable support to the grasper. A deployment user interface is couplable to the movable support and has a proximal end manipulable by a user extracorporeally and a distal end releasably attachable to both the anchor and the grasper, adapted to intracorporeally deploy the anchor into the first tissue and the grasper onto the second tissue. The user interface includes a first actuator having an anchor positioning tool enabling selective deployment of the anchor in the first tissue, and a second actuator enabling selective opening and closing of the jaws of the grasper.
