The first support part 221 and the second support part 231 are shaped to fit the outer wall of the larger diameter end of the inner tube 100 and are both arc-shaped.

In addition, support portions having the same shape as the first support portion 221 and the second support portion 231 may be further added to the inner wall of the side where the outer sleeve 200 is connected to the cover body 500, to further improve the structural stability.

As shown in fig. 5 and 10, the inner wall of the outer cannula 200 is further provided with a guide member 260, the guide member 260 is located between the first support member 220 and the second support member 230, i.e. located in the second channel 400, the guide member 260 is provided with a guide groove 261, after passing through the second inlet 410, the therapeutic device can enter the second channel 400 along the guide groove 261 and finally pass out from the second outlet 420, thereby improving the moving efficiency of the therapeutic device in the second channel 400.

Referring to fig. 5 and 10, one end of the guide 260 is flush with the end of the outer sleeve 200 connected to the cap body 500, and the other end extends into the second channel 400.

The guide 260 may be integrally formed with the outer sleeve 200.

The outer surface of the outer sleeve 200 is coated with a hydrophilic layer, namely the outer surface of the outer sleeve 200 has a lubricating type, so that the comfort of inserting the outer sleeve 200 into the tube cavity is improved, and the application stability of the device is ensured.

When the device is used for treatment, the treatment instrument extends into the second channel 400 from the second inlet 410 and extends out from the second outlet 420, the focus in the cavity of the tube is treated by matching with camera shooting and ventilation operation, the treatment instrument comprises operation forceps, a medicine needle and the like, the focus is subjected to operation or medicine treatment, the operation is simple and convenient, and the treatment is simpler.

The inner sleeve 100, the outer sleeve 200 and the cap body 500 may be made of biological materials, medical materials, nano materials or the combination thereof.

To sum up, the lumen is exploreed to the transparent blind end of interior sheathed tube of camera lens permeable, and through letting in gas to first passageway, it is unclear to prevent to appear the camera lens and make a video recording, and then can realize accurate discernment pathological tissue to accurately make treatment judgement, can treat the focus of lumen through the second passageway, has had visual exploration concurrently and has treated dual function, effectively improves the availability factor, is favorable to popularizing and applying. In addition, the surface of the outer sleeve is coated with a hydrophilic layer, so that bacteria are prevented from being adsorbed, and the phenomena of cross infection/infection and the like are effectively avoided. Also has the advantages of good sealing performance, simple and convenient treatment operation, low use cost and the like.
