Abstract

A handle assembly includes two arms and a latching lever. An end effector includes two jaws. A firing assembly includes an actuating beam, a proximal body, and two levers. The actuating beam is slidable relative to the handle assembly and the end effector. The proximal body is coupled to the actuating beam and is housed within either the first arm or the second arm. The first lever is configured to move between a first laterally extending position and a first non-obtrusive position. The first lever is configured to drive the actuating beam and the proximal body relative to the handle assembly in the first laterally extending position. The second lever is configured to move between a second laterally extending position and a second non-obtrusive position. The second lever is configured to drive the actuating beam and the proximal body relative to the handle assembly in the second laterally extending position.
