For reaching above-mentioned technical purpose, this utility model is achieved by the following technical programs:

A kind of rectoscope with aerating gasbag described in the utility model, comprise rectoscope main body and the rectoscope sheath pipe supporting with it, described rectoscope main body comprises hard work end, light source joint, eyepiece input or data-interface, described hard work is penetrated with instrument channel in end, the first end of front end of described hard work end is provided with light-conductive optic fibre, optical lens, instrument channel outlet, described rectoscope sheath pipe comprises sheath tube end, the sheath pipe clamp mouth coordinating with rectoscope main body, the front end of described sheath tube end is provided with at least one aerating gasbag, described rectoscope sheath pipe is provided with inflating catheter for air bag is inflated and for air bag being carried out to the topping up passage of topping up, inflating catheter is inflated aerating gasbag, make it to expand, topping up channel function is the filling liquid chamber of being put in prison.

In this utility model, the shape after described aerating gasbag expands according to it can be divided into following several:

The first, is spherical after described aerating gasbag inflation, diameter≤80mm after its inflation, and the quantity of described aerating gasbag is one or two or three.

The second, is cylindrical shape after described aerating gasbag inflation, after its inflation, sheath tube end is expanded.

In this utility model, the sheath tube end of described rectoscope sheath pipe is disposable plastics or reusable metal material.

In this utility model, the diameter≤15mm of described its hard work end, length >=100mm.The optical system of described rectoscope main body is prism optical system or fiber optic fiber optical system or electronic CCD optical system.

In addition, described instrument channel is linear type.

Compared with prior art, the beneficial effects of the utility model are:

Rectoscope with aerating gasbag described in the utility model, it can not only be by using air bag to be used for expanding in rectal cavity, and can fill liquid, with assurance, get a clear view, the instrument channel of rectoscope main body can pass into apparatus and coordinate operation, effectively improve the accuracy of inspection, diagnosis, operation, made up the deficiency of current diagnosis and treatment method.

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 PROCTO schematic diagram with aerating gasbag described in the utility model, it comprisesrectoscope sheath pipe 1 and supporting rectoscopemain body 2 with it.

As shown in Figure 2, described rectoscopemain body 2 compriseshard work end 21,light source joint 22, eyepiece input or data-interface 23, in describedhard work end 21, is penetrated withinstrument channel 24, and describedinstrument channel 24 is linear type.As shown in Figure 3,211 places, the first end of the front end of describedhard work end 21 are provided with light-conductive optic fibre 231, optical lens 221, instrument channel outlet 241.
