An instrument for use in endoscopic biopsy procedures comprising biopsy forceps which utilize a simple and cost effective construction. The apparatus of the invention eliminates the use of an outer housing and utilizes a simplified hinge assembly in conjunction with simple activation of the biopsy jaws. By eliminating the outer housing, the rigid portion of the device is greatly reduced thereby reducing the potential for damage to the instrument or to the narrow channel of the endoscope through which the instrument is inserted and retrieved. The apparatus includes an outer flexible tubular sheath which carries a control wire extending through the sheath. The control wire is movable within the flexible sheath, and includes an operating mechanism coupled to a first end of the tubular sheath for controlling movement of the wire within the sheath. The device further includes a pair of jaw assemblies and a simplified activator for opening and closing the jaws. The control wire actuates the opening and closing of the jaw assemblies and, more specifically, controls an activator for opening and closing the jaw assembly which reduces the number of articulating surfaces or points associated with the jaw assemblies.
