The specific embodiment
Below in conjunction with accompanying drawing, this utility model is described in further detail:
Embodiment mono-:
As shown in Figure 1, the SIG schematic diagram with aerating gasbag described in the utility model, it comprises romanoscope sheath pipe 1 and supporting romanoscope main body 2 with it.
As shown in Fig. 1~Fig. 5, described romanoscope main body 2 comprises hard work end 21, light source joint 22, eyepiece input or data-interface 23, in described hard work end 21, be penetrated with instrument channel 24, intake tunnel 25, exhalant canal 26, described instrument channel 24 is linear type, described intake tunnel 25, exhalant canal 26 and the public passage of instrument channel, 211 ports, the first end of front end of described hard work end 21 are provided with light-conductive optic fibre 221, optical lens 231, instrument channel outlet 241.The first end 211 of front end of described hard work end 21 is bendable end, and described romanoscope 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.
