An operative electronic video endoscope (10) includes an elongated tubular barrel (12) having a distal end and a proximal end to which a pistol grip handle (14, 38) is attached. A bundle of light transmitting fibers (50) extend through the barrel (12) and have distal ends adjacent the distal end of the barrel. A straight operative channel (16) extends between the fibers within the barrel, the channel having a distal end coterminous with the distal end of the barrel and a proximal end extending through the handle for receiving an operative instrument (20). Electronic image producing means (22) extends between the fibers (50) within the barrel along side of the operative channel (16) and includes an image receptor (22) at the distal end of the barrel. The proximal ends of the light fibers exit the pistol grip portion (38) of the handle (14) for connection to a light source (56). The electronic image producing means (22) includes an electronic cable (36) which exits the pistol grip portion (38) of the handle (14) for connection to an electronic image processor (44). |
