SURGICAL STAPLING AND CUTTING APPARATUS - DEPLOYMENT MECHANISMS, SYSTEMS AND METHODS

摘要

A surgical stapling device is configured for use in open and/or laparoscopic surgical procedures. The device includes a handle assembly, a shaft assembly coupled to the handle assembly, and an end-effector coupled to the shaft assembly. The end-effector comprises of a jaw assembly configured to clamp, staple, and/or cut a target tissue. The handle assembly comprises of a trigger element that can activate a drive assembly to advance a deployment assembly to staple and/or cut the aforementioned target tissue. The deployment assembly comprises of a deployment slide member to either advance the deployment assembly in a first direction or retreat the deployment assembly in a second direction.
