Abstract
A ratchet release mechanism for a medical device. The release mechanism permits both a smooth and a stepped actuation of a grasper on a distal end of the medial device. The medical device has a fixed handle and a movable handle. The release mechanism comprises an elongated toothed plate arrangement supported in a release housing and an elongated smooth plate arranged adjacent the toothed plate arrangement in the release housing. The release housing is pivotably supported between the handles to permit the handles to move in a stepped or a smooth manner to effect actuation of the grasper.
