The specific embodimentBelow with reference to the accompanying drawings, embodiments of the invention are described.

Fig. 1 is the structural representation of existing endoscopic apparatus, comprises probe 1, main frame 3 and is connected popping one's head in 1 and the insertion tube 2 of main frame 3.Insertion tube 2 can be hard tube or soft pipe, and the inside has optical fiber tube or holding wire (omitting among Fig. 1), and insertion tube 2 is terminal for popping one's head in 1, and probe 1 generally is columned.1 the inside of popping one's head in is provided with optical lens or electronics camera lens, to pop one's head in by insertion tube 2 during use and 1 insert the chamber shape pipeline organ of human body such as trachea, esophagus, anus etc., main frame 3 has optical observation mirror or the electronic display with probe 1 cooperating, and 1 pair of human internal organs is observed by popping one's head in.

Probe 1 of the present invention needs to cooperate insertion tube 2 and main frame 3 work in use too.And main frame 3 is provided with medium injection device 4, is provided with the media lines 5 of hollow in insertion tube 2 the insides, and media lines 5 is connected to medium injection device 4.The other end of injection device 4 also can be connected with the media Containers 6 that is used for the store fluid medium.(when medium adopts air, also can not need media Containers 6).As Fig. 2.

Structure such as Fig. 3 of the probe 1 of endoscope of the present invention.1 rear end of popping one's head in is connected with

insertion tube

2, and 1 the inside of popping one's head in includes camera lens (prior art, accompanying drawing do not indicate) equally.Side surface at the front end of columned probe 1 is provided with a ring annular groove 11; But be fixed with the annular leather bag 12 of injected media on the annular groove 11, annular leather bag 12 has cross over pipe 13.Annular leather bag 12 adopts thin flexible material with toughness and elastic, nonhazardous such as silica gel or medical grade rubber to make, can directly rely on elasticity to be locked on annular groove 11, perhaps will be fixed on the annular groove with the sticking card of annular groove 11 contacted parts.Annular leather bag 12 other places except following the UNICOM of cross over pipe 13 are airtight, when injecting fluid media (medium) such as gas or liquid, annular leather bag 12 expands and heaves, (being similar to the lifebuoy of inflation), and be enclosed within on the annular groove 11, the height of heaving is decided on probe diameter, generally can be between 0.5 to 1 times of diameter; When taking out medium, annular leather bag 12 shrinks and is adjacent on annular groove 11.Cross over pipe 13 enters probe 1 inside (cross over pipe enters the aperture place can do encapsulation process) by the aperture that is arranged on above the annular groove 11, is connected with the media lines 5 of insertion tube 2 the insides, and media lines 5 is connected to the medium injection device 4 of main frame 3 the insides.Described annular groove 11 is preferably annular V-type groove, and promptly the cross section of groove is a V-type, makes annular leather bag 12 take out medium, can be better and more the lowland shrink and be adjacent in groove the inside, insertion that is more convenient for popping one's head in and extraction.

Described fluid media (medium) can be a gas, as nitrogen or air; Or liquid, as pure water or normal saline; Decide use location according to endoscope.Such as: be used in trachea, then medium can adopt air, is used in anus, then can adopt water.When purpose is that escape of liquid appears in contingency, can not damage human body.
