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.

Dependent claims

An apparatus, the apparatus comprising:

(a) a handle assembly, wherein the handle assembly comprises:
(i) a first lateral side,
(ii) a second lateral side,
(iii) a first arm,
(iv) a second arm, wherein the second arm is configured to pivotably couple with the first arm at a proximal pivot location, and
(v) a latching lever pivotably coupled with the first arm at a distal pivot location;
(b) an end effector, wherein the end effector comprises:
(i) a first jaw extending distally from the first arm, and
(ii) a second jaw extending distally from the second arm, wherein the second jaw is configured to pivot relative to the first jaw between an open configuration, a partially closed configuration, and a fully closed configuration, wherein the latching lever is configured engage the second arm or the second jaw to pivot the second jaw from the partially closed configuration toward the fully closed configuration;
and
(c) a firing assembly configured to sever tissue captured between the first jaw and the second jaw in the fully closed configuration, wherein the firing assembly comprises:
(i) an actuating beam slidable relative to the handle assembly and the end effector,
(ii) a proximal body coupled to the actuating beam, wherein the proximal body is slidably housed within either the first arm or the second arm,
(iii) a first lever associated with the first lateral side configured to move between a first laterally extending position and a first non-obtrusive position, wherein 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, and
(iv) a second lever associated with the second lateral side configured to move between a second laterally extending position and a second non-obtrusive position, wherein 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.
