ABSTRACT:
An endoscope has a tubular shaft for receiving a viewing lens and a treatment instrument. The shaft has a distal end portion of channel-shape, providing a viewing window for the viewing lens. The circumference of the shaft is of oval cross-section around which the wall of the channel-shaped portion extends asymmetrically. An aperture recess forming an additional viewing window for the viewing lens is provided in the wall of the end portion. The endoscope is particularly suitable for use in endoscopic operations in the female breast, since the additional viewing window allows inspection of an implant before opening a capsule surrounding the implant.
