Abstract: A medical device and related methods are disclosed. The device has a plurality of telescoping sections and an outer sheath at least partially encapsulating the plurality of telescoping sections. The outer sheath is configured to prevent buckling of the plurality of telescoping sections. A first one of the plurality of telescoping sections has a first notch. A second one of the plurality of telescoping sections has a head portion. The first notch of the first one of the plurality of telescoping sections is configured to slidably receive at least a portion of the head portion of the second one of the plurality of telescoping sections. The first one and the second one of the plurality of telescoping sections are slidable relative to each other between and extended setting and a retracted setting.

Abstract: An electrosurgical instrument has a movable tissue cutting mechanism, a first elongated shaft housing at least a proximal portion of the movable tissue cutting mechanism, and a pair of jaws for clamping tissue. Each jaw of the pair of opposing jaws is rotatable relative to the first elongated shaft, and the movable tissue cutting mechanism is slidable relative to the first elongated shaft. A first link has a distal end rotatably coupled to a proximal one of a pair of non-conductive bushings in the first jaw and a proximal end rotatably coupled to a second elongated shaft, the second elongated shaft interior of and translatable relative the first elongated shaft.
