Abstract
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 clamp drive assembly to clamp the aforementioned target tissue. The clamp drive assembly comprises of a clamp slide member to either advance the clamp drive assembly in a first direction or retreat the clamp drive assembly in a second direction. The clamp drive assembly is movably coupled to a clamp driver member. Movement of the clamp driver member operates clamping operations of a jaw assembly of the surgical stapling device.
