ABSTRACT:
An endoscopic bioptome includes a jaw assembly, a tubular member, and a control wire extending through the tubular member, where the distal end of the control wire and tubular member are both coupled to the jaw assembly, and the jaw assembly includes a pair of opposed end effectors having resilient arms and a pair of opposed resilient anchors oriented orthogonal of the end effectors. Preferably the end effectors and the anchors are formed from a super-elastic metal. The anchors are blunt-tipped and also include angled portions which urge the anchors away from each other. The end effectors include resilient arms having proximal angled portions and distal portions which terminate with end effector jaw cups. The proximal angled portions urge the jaw cups away from each other. The jaw cups each have a sharp cutting rim. Another embodiment of the jaw assembly include jaw cups having radially arranged teeth. The proximal portion of each arm and anchor is coupled to a threaded base member which is thread into the coil. The distal end of the wire is coupled to a sleeve. The proximal ends of the coil and wire are coupled to a manual actuation means for axially displacing one of the coil and wire relative to the other. Axial movement of the wire relative to the coil moves the sleeve over the arms of the end effectors and also over the anchors, thereby forcing the jaw cups together in a biting action and moving the anchors radially inward.
