DEVICE: TiLock (M719GL304850)

A small device designed to attach to a surgical power tool (e.g., the proximal end of a surgical drill handpiece) or a manual surgical instrument (e.g., a screwdriver) to define the torque effect of that tool allowing the surgeon to apply the correct torque, e.g., when tightening an orthopaedic fixation screw during a surgical intervention. It is typically made of high-grade stainless steel or synthetic materials and includes a built-in clutch mechanism. It is available in various shapes, sizes and torque ranges. It will normally provide an indication to the surgeon when the pre-set torque level is reached with an audible click and release of rotational traction. This is a reusable device.
