Abstract
An end effector that can have an upper jaw and a lower jaw. A wrist can connect the end effector to an elongated shaft. A beam member can be arranged to translate within the upper and lower jaw. An actuation assembly can have a pushing assembly configured to transfer compressive force to the beam member and a pulling assembly configured to transfer tensile force to the beam member.

-42. (canceled)
An apparatus comprising:
- an end effector comprising an upper jaw and a lower jaw, wherein a wrist connects the end effector to an elongated shaft;
- a beam member arranged to translate within the upper jaw and the lower jaw, the beam member having a first portion for moveably coupling to the upper jaw and a second portion for moveably coupling to the lower jaw;
- a pulling assembly that is connected to the beam member, is flexibly housed within the wrist, and applies tensile force to the beam member;
- and
- a pushing assembly that is connected to the beam member, is flexibly housed within the wrist, and applies compressive force to the beam member.
