1. An end effector for a screw fastener instrument, the end effector comprising:
- a cam spiral driver;
an inner tube assembly that supports an outer tube; and
a cam spiral sub-assembly disposed in the inner tube assembly and operatively connected to the cam spiral driver, the cam spiral sub-assembly configured to rotate and translate in response to rotation of the cam spiral driver, wherein rotational and translational movement of the cam spiral sub-assembly causes at least one screw fastener to dispense from the outer tube.
