Claim:
1. A surgical apparatus comprising: a surgical instrument comprising an elongated shaft extending along a longitudinal axis from a proximal end to a distal end, a working element coupled to the distal end of the elongated shaft for manipulating tissue; an endoscope having a tubular body including an image fiber, an endoscopic lens coupled to a distal end of the tubular body and operably coupled to the image fiber, the endoscopic lens defining a viewing field about a central axis; the endoscope mounted to the elongated shaft of the surgical instrument, the endoscopic lens protruding from an outer longitudinal surface of the elongated shaft, the central axis of the viewing field being oblique to the longitudinal axis of the elongated shaft and intersecting the outer longitudinal surface, the working element located within the viewing field and separated from the central axis by a distance; wherein a portion of the central axis of the viewing field extending from the distal end of the tubular body of the endoscope in a direction towards the working element of the surgical instrument diverges from the elongated shaft and the working element of the surgical instrument without intersecting the elongated shaft or the working element of the surgical instrument; and wherein the central axis of the viewing field intersects the longitudinal axis of the elongated shaft of the surgical instrument at an intersection point that is located between the proximal and distal ends of the elongated shaft and is spaced a first distance from the distal end of the elongated shaft and wherein the endoscopic lens of the endoscope is located between the proximal and distal ends of the elongated shaft and is spaced a second distance from the distal end of the elongated shaft, the first distance being greater than the second distance.
