In the present invention, the shape after described aerating gasbag expands according to it can be divided into following several:

The first, be spherical after described aerating gasbag inflation, diameter≤50mm after its inflation, and the quantity of described aerating gasbag is one or two or three.

The second, be cylindrical shape after described aerating gasbag inflation, makes the sheath tube end expand after its inflation.

In the present invention, the sheath tube end diameter≤25mm of described romanoscope sheath pipe, its length range≤250mm.

In the present invention, the sheath tube end of described romanoscope sheath pipe is disposable plastics or reusable metal material.

In the present invention, described hard work end total length 250～300mm, its front end≤50mm is bendable end, minimum 30 degree of the controlled bending of this bendable end.

In the present invention, the optical system of described romanoscope main body is prism optical system or fiber optic fiber optical system or electronic CCD optical system.

In the present invention, described instrument channel is linear type, its internal diameter 〉=3.0mm, described intake tunnel and exhalant canal and instrument channel highway.

Compared with prior art, the invention has the beneficial effects as follows:

Romanoscope with aerating gasbag of the present invention, it can not only be used for the sigmoid colon chamber by using aerating gasbag, can, by inflation to obtain valuable working place, conveniently pass into the apparatus assisted surgery.

The specific embodiment

The present invention is described in further detail below in conjunction with accompanying drawing:

Embodiment one:

As shown in Figure 1, the SIG schematic diagram with aerating gasbag of the present invention, it comprisesromanoscope sheath pipe 1 and supporting romanoscope main body 2 with it.

As Fig. 1～shown in Figure 5, described romanoscope main body 2 comprises hard work end 21, light source joint 22, eyepiece input or data-interface 23, be penetrated with instrument channel 24, intake tunnel 25, exhalant canal 26 in described hard work end 21, described instrument channel 24 is linear type, described intake tunnel 25, exhalant canal 26 and the public passage of instrument channel, first 211 ports, end of the front end of described hard work end 21 are provided with light-conductiveoptic fibre 221,optical lens 231, instrument channel outlet 241.The first end 211 of the front end of described hard work end 21 is bendable end, and describedromanoscope 1 is provided with the gauge tap 27 of first end 211 bendings of controlling hard work end 21.Fig. 2～Fig. 4 is by corresponding three case of bending A2, B2 of first end 211 and the structural representation of C2 controlled of gauge tap 27 present three state A1, B1 and C1, by different angle of bend, adapt to observation and the treatment of sigmoid colon pathological changes under different situations, applied widely.
