Orthopaedic counter-torque/rod-pushing instrument

Intended purpose

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 set screw 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.
