Abstract
An apparatus includes a handle assembly, an end effector, a firing assembly, and a release assembly. The handle assembly includes first and second arms and a latching lever. The end effector includes first and second jaws. The firing assembly is configured to sever tissue captured between the jaws. The release assemble is configured to urge the latching lever away from the first arm to pivot the second jaw from a fully closed position to a partially closed position.
Claims20
An apparatus, the apparatus comprising:
- (a) a handle assembly, wherein the handle assembly comprises:
- (i) a first arm,
- (ii) a second arm, wherein the second arm is configured to pivotably couple with the first arm at a proximal pivot location, and
- (iii) 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;
- (c) a firing assembly configured to sever tissue captured between the first jaw and the second jaw in the fully closed configuration;
- and
- (d) a release assembly configured to urge the latching lever away from the first arm to pivot the second jaw from the fully closed position toward the partially closed position.

An apparatus, the apparatus comprising:
- (a) a first portion comprising:
- (i) a first handle, and
- (ii) a first jaw portion extending distally from the first handle;
- (b) a second portion comprising:
- (i) a second handle,
- (ii) a second jaw extending distally from the second handle, and
- (iii) a latching projection, wherein the second portion is configured to pivotably couple with the first portion at a proximal location;
- (c) a latching lever pivotably coupled with the first portion, wherein the latching lever is configured to engage the latching projection to pivot the first jaw and the second jaw from a partially closed configuration toward a fully closed configuration;
- (d) a firing assembly configured to sever tissue between the first jaw and the second jaw in the fully closed position;
- and
- (e) a release assembly configured to urge the latching lever away from the first portion to pivot the second jaw and the first jaw from the fully closed configuration toward the partially closed configuration.
