Abstract

A biopsy forceps as disclosed that has a flexible hollow support cable with an insulating layer surrounding the support cable on its outer surface. An electrically conductive control wire extends through a central passage of the hollow support cable and has an insulating layer surrounding the portion of the control wire that is inside the support cable. The control wire is connected to an electrically conductive mount at a distal end of the control wire. The electrically conductive mount supports the pair of electrically conductive metal jaws which are pivotal and which have curved walls with sharp cutting edges which together form an enclosure for purposes of excising tissue. The control wire is electrically connected to a source of electrical current to permit selective energizing of the control wire as well as mechanical closing of the jaws when excising tissue, so as to provide simultaneous energizing of the mount, the pivotal jaws and also conductive spear for stabilizing and holding tissue that is positioned between the jaws.
