Surgical instrument handle, torque-limiting

A surgical instrument handle with torque-limiting function is a hand-held tool used by surgeons to attach to the proximal end of instruments like screwdrivers during orthopaedic procedures. It enables controlled manual rotation of bone screws or setscrews while preventing over-tightening through a built-in torque-limiting mechanism that provides tactile or audible feedback when the preset limit is reached.

This category of device is designed for reuse and is typically constructed from metal or synthetic materials such as polysulphone, often featuring a T-shaped grip for ergonomic handling. Regulation of these devices is based on their intended use and design, with classification determined by jurisdictional authorities according to risk, and they are supplied as reusable components intended for multiple clinical uses after appropriate reprocessing.
