Screwdriver, surgical

Intended purpose

A tool that fits into a screw head in order to apply rotation to tighten/loosen/remove a screw during a surgical procedure. It typically has a high-grade stainless steel shaft with a distal end dedicated to fit into a screw head that may be slotted, Phillips (cross head), Pozidriv (Supadriv), Torx, Hex (Allen), Robertson (square), spanner head (twin pins), Polydrive, or one-way (clutch). The proximal end of the shaft may have a handle for manual use, or it may have a profiled tang that fits into an interchangeable screwdriver handle, a manually-operated chuck, or a power driver. Some types may include a torque-measuring gauge. This is a reusable device.
