  • Patent number: 5562682
    Abstract: A surgical instrument for endoscopic surgery is provided which is capable of articulation in the endoscopic arm portion of the instrument to supply the surgeon with improved adjustability in the orientation of the arm. The instrument provides means through which the surgeon can change the angle at which the instrument actuates. This articulation functions without disruption of the rotatability of the arm or the mechanism for applying staples, clips, and the like. Because this articulation can be performed in conjunction with a rotation feature, a large degree of adjustment is generated.
