Physical description

Four-pronged metal surgical instrument. Consists of a handle and a short shaft with a metal cross shaped base section to which four long, curved prongs are attached. Each prong is capped by a detachable foot, consisting of a grooved metal sleeve with a base that forms the shape of a quarter circle. When the device is closed, the four feet line up with each other to form a complete circle at the base. There is large handle with four spokes at the top of the device for opening and closing the instrument, and a circular knob is affixed to the top of the handle to lock it in place when required. The shaft of the instrument is engraved with gauge markings to measure how open the instrument is when in use.
