Claim 0:
1. A surgical tool, comprising:
a first piston;
a second piston that is independent from the first piston and is located rearward of the first piston;
a first strike surface;
a second strike surface;
a sealed chamber configured to contain compressed gas therein, the chamber defining a longitudinal axis extending between forward and rearward ends of the chamber, the first and second pistons each being positioned along the longitudinal axis of the chamber; and
a motor configured to drive movement of the first piston in a first direction and to drive movement of the first piston in a second direction that is opposite to the first direction, the movement of the first piston in the first direction being configured to cause compression of the gas in the chamber and the first piston to strike the first strike surface and thereby communicate a rearward force to an end effector operatively coupled to the first piston, and the movement of the first piston in the second direction being configured to cause compression of the gas in the chamber and the second piston to strike the second strike surface and thereby communicate a forward force to the end effector operatively coupled to the second piston.
