Abstract

The invention discloses a surgical instrument for dissecting tissue. The surgical instrument includes an end effector supported on a distal end of an elongated shaft, a clamping rod, and a measurement mechanism. The clamping rod extends through the elongated shaft and is operatively associated with the end effector to transition the first and second jaw members between open and clamped positions. The measurement mechanism includes a cylinder, a biasing member, and a locking member. The biasing member is disposed within the cylinder and is disposed over a proximal end of the clamping member distal to a piston disposed at a proximal end of the clamping rod. The cylinder is operatively associated with a moveable handle such that as the moveable handle is moved towards an actuated position, the cylinder is moved proximally such that the biasing member urges the clamping rod proximally to move the first and second jaw members towards the clamped position.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of and priority to U.S. Provisional Patent Application No. 62 / 128,086, filed March 4, 2015, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to surgical instruments, and more particularly, to surgical instruments for dissecting tissue. Background technique [0004] Abdominal surgery is well known as a contributor in the development of abdominal adhesions. Abdominal adhesions are bands of scar tissue that develop between tissues and organs in the abdomen that cause them to stick together. These adhesions can range from being fragile as "spider webs" to dense as "concrete," which leads to complications for patients years after surgery. [0005] Traditional methods of dissecting abdominal adhesions include surgery. However, subsequent abdominal surgery increases the risk that additional adhesions will develop. Additio...
