Abstract:
A retraction system and method are provided for retracting tissues surrounding a surgical site. In one aspect, a method including engaging slide connections between a guide dilator and a plurality of tissue engaging members and sequentially enlarging an incision using the guide dilator and the plurality of tissue engaging members. In another aspect, a method of inserting a plurality of tissue engaging members into an incision including fixing tip portions of the plurality of tissue engaging members in an insertion configuration, advancing the tip portions into an incision, and restricting movement of the tip portions away from the insertion configuration. A guide dilator system comprising an elongate body, a plurality of tissue engaging members, and slide connections between the elongate body and the tissue engaging members is also provided.

Claim (Index 9):
A retractor for enlarging an incision, the retractor comprising:\n a frame; a plurality of tissue engaging members for being inserted into an incision; a plurality of sliders configured to connect the tissue engaging members to the frame, each slider being shiftable between an extended position and a retracted position; a rotatable drive member associated with one of the sliders and rotatable in a retracting direction to cause the one slider to shift toward the retracted position and an extending direction to cause the one slider to shift toward the extended position; a worm gear operably coupled to the drive member; a worm screw engaged with the worm gear and rotatable in a first direction to cause rotation of the worm gear and the drive member coupled thereto in the retracting direction, the worm screw being rotatable in an opposite, second direction to cause rotation of the worm gear and the drive member coupled thereto in the extending direction; and a clutch having a release mode wherein the clutch decouples the worm gear from the drive member and permits the drive member to rotate relative to the worm gear as the one slider shifts toward the retracted or extended position.
