Abstract
A torque limiting ratcheting handle for a medical instrument is provided that includes a ratchet shifter, a tool connector, a torque coupler, and a rear power housing. The handle provides clockwise and counterclockwise ratcheting and limits the amount of torque in one direction while allowing for maximal torque in the opposite direction. In one aspect, the ratcheting handle may include a drive shaft removeably connected to a power tool or, alternatively, to a handle grip for manual manipulation.
