A biopsy forceps having a disposable cable formed by helically wound wire with distal and proximal ends. The helically wound wire forms a passage therethrough from the distal to the proximal end. The biopsy forceps includes a reusable forceps instrument assembly which has a control wire passing through the passage. A pair of sharpened jaws are located at the end of the control wire and are joined to a jaw mount by means of pivot. The jaw mount includes a socket for selective coupling and uncoupling to the distal end of the helically wound wire, by rotating the distal end of the helically wound wire into or out of the socket so that the helically wound wire of the support cable can be uncoupled from the jaw mount and discarded, while the forceps assembly, including the jaw mount together with the control wire and pivotally mounted jaws can be removed as an entire assembly and resterilized for use with another support cable. |
