发明名称 Jaw assembly having progressively larger teeth and endoscopic biopsy forceps instrument incorporating same
摘要 An endoscopic forceps jaw assembly for an endoscopic instrument includes a pair of articulating opposed jaws each having a jaw cup. The jaw cups are provided with teeth which increase in height from the proximal end of the jaw cup to the distal end. The jaws are rotatable relative to each other about a common axis and define an open position and a closed position. When the jaws are rotated toward the closed position, the teeth interleave substantially simultaneously. An endoscopic instrument utilizing the jaws of the invention is also provided and further includes an actuation handle, a tubular member, and a control member. The jaw assembly is coupled to the distal end of the control member and rotatably coupled to the distal end of the tubular member, such that the pair of articulable opposed jaws open and close by rotating in response to movement of the control member relative to the tubular member. The jaws may also be electrically conductive and coupled to an electrocautery voltage supply.
