  • Patent number: 5725536
    Abstract: This invention provides an articulated surgical instrument for use in laparoscopic surgical procedures including, in general; a handle, an elongated shaft, and an articulating tip. The instrument further includes a proximal rod, a desensitizing link, and a distal rod. The proximal rod is disposed in the shaft for reciprocating movement between a proximal position and a distal position. The distal end of the proximal rod is coupled to the desensitizing link at a first pivot point. The desensitizing link is disposed within the shaft for rotational movement about a second pivot point in response to the reciprocating movement of the proximai rod. The proximal end of the distal rod is coupled to the desensitizing link at a third pivot point.
