Socket screwdriver , (S 2.55mm; bore 12.5mm)

A non-driven tool inserted into the head of a screw (e.g. slotted screw, Phillips/hex screwdriver head) to apply rotation to insert/remove a screw (e.g. craniofacial screw, dental screw) in a patient simultaneously with a surgical procedure (e.g. orthopaedic, dental, computerised surgery, image registration). It may also be used to connect/disconnect other articles fixed to the patient (e.g., implant components, coordinate tags). The proximal end of the product may have a handle for manual use or a profiled shank that is inserted into an independent chuck or drive tip; typically made of metallic and/or polymeric materials. It is a reusable product.
