Abstract
A retractor for endoscopic surgery, having a first shaft portion, in which an actuation device is movable, and a second shaft portion coupled pivotably thereon. A transmission arm is articulated on a distal end of the actuation device. A retraction structure is connected to a distal end of the second shaft portion, which retraction structure can be releasably coupled, with its other end, to the second shaft portion via a coupling device. The coupling device has a slide, which is guided in the second shaft portion. The transmission arm is articulated on the second shaft portion by way of a peg-and-slot connection and is operatively coupled to the slide in order to move the latter longitudinally, wherein the coupling device can be transferred to a release state by longitudinal movement of the slide. An operating method for the retractor is also disclosed.
