Abstract
An instrument for removing a biopsy specimen from the cervix. The instrument is a forceps-like device having opposing jaws that open and close. A blade on one jaw has a cutting edge which includes a sharp point that initially undercuts the specimen. As the point emerges, the sides of the cutting edge slice the specimen away from the cervix. The other jaw has a pair of teeth which grip and stabilize the cervix and a recess which receives the blade when the jaws are closed. The blade is disposable and is attached to a block which has a dovetail joint with the jaw so that it can be slipped onto and off of the jaw for replacement of the blade.
