ABSTRACT:
A biopsy forceps device includes a handle assembly having a handle portion and a hub portion. An elongated flexible hollow body portion preferably in the form of a coiled spring guide wire extends from the hub portion to a forceps assembly. A control wire extends through a lumen in the guide wire as well as a lumen in the hub portion and is coupled at one end to the handle portion and at the other end to the forceps assembly. A flexible coupling interconnects the hub portion with the handle portion so that the hub portion may be angularly displaced with respect to the distal end of the handle portion. The flexible coupling takes the form of a ball and socket arrangement with the ball being carried by the hub portion and the socket being carried by the handle portion.
