DEVICE: Counter Torque Wrench (M73922017006)

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.

A hand-held, manual, tube-like surgical instrument with a right-angled handle designed to apply a rotational force that opposes the directional force of torque when tightening (locking) a screw or screw head setscrew with a screwdriver, inserted down the instrument's hollow centre, during orthopaedic surgery. In addition, it may be used to push (seat) an orthopaedic rod into the slotted screw heads of screws that have been inserted into bone (e.g., vertebrae). It is typically made of high-grade stainless steel or titanium alloy, and synthetic materials. This is a reusable device.
