A hand-held manual surgical instrument designed to attach to the proximal end of a surgical instrument (e.g., a screwdriver shaft) to allow the surgeon to perform manipulations with the instrument, such as manual rotation of a bone screw or reamer; it does not include a torque-limiting function. The device is typically made of metal and/or synthetic material and may have a straight or T-shaped handle grip which may include additional features such as a ratchet mechanism to allow the surgeon to maintain a constant hold on the handle when providing rotation in one direction. This is a reusable device.
