Abstract
A surgical trephine is adapted for boring an opening in tamped bone chips and includes a hollow elongate body portion having an internal bore and the distal end of which has an annular cutting rim. A piston is located in the bore with a piston surface facing towards the cutting rim and a tool for moving the piston in the bore. With this device an elongate cavity can be cut in the bone chips. The debris from the cutting the bore enters the distal end of the internal bore and slowly pushes the piston up the bore away from the distal end. When the hollow elongate body portion is withdrawn from the cavity, the chips can then be easily dislodged from the bore by displacing the piston.
