A spike-like, orthopaedic, surgical instrument that is used to bore holes in bone. It is typically designed as a straight or slightly curve rod-like instrument with a sharp, trocar-like point at the distal end and a T-shaped handle at the proximal end. It is manually-operated by the surgeon who rotates the point back and forth on the bone whilst exerting pressure onto the handle. This operation will penetrate the hard outer bone and create a passage into, e.g., a medullary canal. It is typically made of high-grade stainless steel, titanium (Ti) and a synthetic material for the handle (e.g., Tufnol). This is a reusable device intended to be sterilized prior to use.
