Definitions
- An endoscope comprises an endoscopic tube, which consists of communication part and insertion part, interconnected by a handle.
- the length of an endoscopic tube could be 3,2 meters long and more.
- the above mentioned functions are ensured by: o channels (see Endoscope Reprocessing: Current Status of Disinfection
- Endoscopes are expensive and reused; the more frequent - the higher is its economical efficiency.
- the usage frequency depends on the speed of reprocessing of an endoscopic tube: washing, disinfection and, in case of necessity, sterilization.
- An endoscopic tube is a potential spreader of infectious hepatitis, AIDS and others infection diseases.
- the locating places of the blood, tissues, biology secret, contents of the investigated organ of previous patient, are channels and valves of an endoscopic tube.
- the key moment of reprocessing is washing.
- the outward surface of an endoscopic tube is washed easily.
- the valves are washed in disassembled state because of their complicated configuration, presence of angular, blind and buried cavities.
- An instrumental channel (its diameter is about 3 mm) is brushed and washed by liquid flow.
- the present invention excludes the recommended way.
- an endoscopic tube which comprises channels and valves that interconnect the pressure sources with an investigated cavity, and among them - the instrumental channel.
- the purpose of the present invention - to provide a safe, quick and cheap reuse of an endoscopic tube, moreover - a simplification of its design, the technical task - to create an endoscope with an endoscopic tube without cavities requiring a protracted and complicated reprocessing.
- the technical result of solving of this task will be an endoscope, comprising:
- pressure sources • an endoscopic tube, comprising an instrumental channel with a lateral output directed on the objective lens and with a diameter of a direct output close to the diameter of the distal part of instrument,
- valves which at switching off squeeze the lumens of branches of tubular element, but at switching on - release them
- An instrumental channel of the endoscopic tube is universal; it interconnects the investigated cavity with any of pressure sources. At the diameter of a channel and an instrument, for example, of 4 mm and 2,3 mm accordingly, the area of gap between them will correspond to the area of a tube with diameter 3 mm. It is enough for decompression of the investigated cavity, for feeding inside it of gas or liquid without extraction of instrument.
- the lateral output of channel is intended for cleaning of objective lens, at that the direct output should be closed by instrument or by bung.
- a tubular element is a disposable part of the system, that is - it is intended only for one patient. Taking into account its simple design, a cost of tubular element will be rather small. It could be made, for example, from silicon.
- Valves allow to connect selectively one or another source of pressure with an universal instrumental channel.
- the advantage of squeezing valves is, that they do not disturb an integrity and hermecity of tubular element.
- the valves will be key-shaped and placed as a block on the handle of an endoscopic tube.
- the pedal- shaped valves are also permissible.
- Bungs of an universal instrumental channel could be used for endoscopy of gastrointestinal tract when there is a prognosis, that biopsy and other instrumental operations will not be needed. If this supposition will not justify oneself, the bung of the entry into a channel is removed, and the bung of output is squeezed out by an instrument inside the tract.
- the clips could be used for fixing of branches of the tubular element to the communication part of the endoscopic tube. The simple design of the tubular element, of the block of valves and of the clips allows to unite them into a disposable set.
- washing of an endoscopic tube which has no valves and has a single channel with a large of cross-section area will occupy only few minutes.
- This invention will exclude the necessity to buy expensive washing machines and thus will substantially reduce the price of equipment of endoscopic cabinets.
- the invention will influence also on the cost of endoscopes: manufacturing and repair of valve- less single-channel endoscopic tube is perceptibly cheaper, than of existing ones.
- FIG. 1 a handle of an endoscopic tube, a tubular element with a block of valves, the places of connection of a tubular element with an universal instrumental channel and with tubes of pressure sources; on Fig. 2 - a cross-section of the insertion part of an endoscopic tube; on Fig. 3A - a cross-section of the communication part of an endoscopic tube; on Fig. 3B - a cross-section of branches of a tubular element and of clips, which support it; on Fig.
- 3C a cross-section of branches of a tubular element, of clips and a communication part of an endoscopic tube as assembled; on Fig. 4 - a longitudinal section of a block of valves; on Fig. 5A - an end-view of the distal head of the insertion part with an introduced instrument; on Fig. 5B - a butt end of the distal head of the insertion part with an introduced instrument.
- the basic parts of construction are an endoscopic tube, a tubular element, a block of valves.
- the endoscopic tube (note Fig. 1 , 2, 3A, 5A, 5C) comprises:
- the tubular element comprises: 15 - a central tube
- the block of valves 21 comprises:
- the tubular element with the block of valves 21 putted on its branches 17 (note Fig. 1 and 4) and with clips 25 (note Fig. 3B and 3C), which support branches 17 on the communication part 2 of the endoscopic tube, will compose a disposable sterile set.
- the bungs 26, 27 of the entrance 19 and the direct output 7 of the channel 5 could be additionally included in the sets for gastroenterological endoscopes.
- the process of preparation for endoscopy comprises:
- the bung 27 is intended for endoscopes for gastrointestinal tract, as only in this case it can safely go out in a natural way.
- the endoscopic tube After examination the endoscopic tube is to be released from the disposable set and is necessary to immediately proceed with its hand washing.
- the channel 5 is washed through the fitting 6 by the liquid flow and by brush. The quick and safe reprocessing and disinfection of the tube will allow already after 15 minutes to reuse it for a next patient.
