An aim of the invention is to provide a safe, fast and cheap reuse of an endoscopic tube, simplification of its construction; a technical task is creation of endoscope with an endoscopic tube without cavities requiring complicated washing. The endoscope comprises: an endoscopic tube, comprising an instrumental channel (5) with a lateral output on an objective lens and a direct output with a diameter close to the diameter of the distal part of instrument; an element in a shape of a tube, where one end of the tube is bifurcated and adjusted for connection with an instrumental channel and for introduction of instrument, and the other end is branched and adjusted for connection with pressure sources; valves which squeeze the lumens of a branch, but at switching on - release it. On the drawing are presented: a handle (1) of a valveless single-channel endoscopic tube; a tubular element having components (15 - 21); block of valves (21)having components (22 - 24); places of connection of the element with a channel (5) and with the pressure sources. The tubular element, valves, clips (25) compose a disposable sterile set. The valveless single-channel endoscopic tube and the set provide all endoscopic functions. Its washing will become reliable, fast and cheap, and its production and repair will be reduced in price as well. |
