ABSTRACT:
A fan retractor for laparoscopic surgery has a pair of angle-shaped elements with first legs disposed in parallel relationship to one another and second legs extending laterally from the first legs for movement between a juxtaposed collapsed condition and a fanned-out expanded condition responsive to rotation of the first legs about their longitudinal axes. Actuators are provided on the first legs to move the second legs between the collapsed and extended conditions. A first lock engages the actuators to lock the second legs in the extended condition and against movement toward or away from one another. A second lock in the form of a block slidably received on the first legs is selectively engageable between the second legs when in the extended condition. When engaged, the second lock serves both to block the second legs from movement toward one another and to restrain the first legs against movement away from one another.
