Description

A kind of cystoscope with aerating gasbag

Technical field

This utility model belongs to field of medical appliances, is specifically related to a kind of core medical instrument that modern medicine is carried out urological surgery, is a kind of cystoscope with aerating gasbag.

Prior art

At present, cystoscope is the common tool of carrying out urology department inspection or operation.During use, be cystoscope to be entered to the intravesical of human body by urethra, then open light source and obtain the image in cavity, thereby diagnose the state of an illness according to image situation.

But traditional cystoscope is not generally provided with aerating gasbag, its observation space must could obtain by bladder cavity is carried out to topping up, if liquid is revealed, can cause surgical environments to become complicated, is unfavorable for performing the operation and effectively or successfully carries out.

Utility model content

The purpose of this utility model is to propose a kind of cystoscope with aerating gasbag, it can expand the scope of the observation space of observed bladder cavity effectively by aerating gasbag this cystoscope with aerating gasbag, and prevent full overflow, to meet the needs of observing and performing the operation.

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

A kind of cystoscope with aerating gasbag described in the utility model, comprise cystoscope main body and the cystoscope sheath pipe supporting with it, described cystoscope 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 cystoscope sheath pipe comprises sheath tube end, the sheath pipe clamp mouth coordinating with cystoscope main body, the front end of described sheath tube end is provided with at least one aerating gasbag, corresponding inflating catheter for aerating gasbag is inflated and the topping up passage of topping up of being provided with also on described cystoscope sheath pipe, inflating catheter is inflated aerating gasbag, make it to expand, topping up channel function is that filling liquid enters bladder.

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≤20mm 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 cystoscope sheath pipe is disposable plastics or reusable metal material.

In this utility model, the optical system of described cystoscope 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, is convenient to pass into apparatus and coordinates operation.

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

Cystoscope with aerating gasbag described in the utility model, it can not only be by using aerating gasbag to be used for expanding in urethra and bladder cavity, and can fill liquid, with assurance, get a clear view, the instrument channel of cystoscope 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 cystoscopic schematic diagram with aerating gasbag described in the utility model, it comprises cystoscope sheath pipe 1 and supporting cystoscope main body 2 with it.

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

In this utility model, the optical system that described cystoscope main body 2 adopts is prism optical system or fiber optic fiber optical system or electronic CCD optical system.

1. as shown in Figure 4, described cystoscope sheath pipe 1 comprises sheath tube end 11, the sheath pipe clamp mouth 12 coordinating with cystoscope main body 2, the front end of described sheath tube end 11 is provided with an aerating gasbag 13, corresponding inflating catheter 14 for aerating gasbag 13 is inflated and the topping up passage 15 of topping up of being provided with also on described cystoscope sheath pipe 11,14 pairs of aerating gasbags of inflating catheter are inflated, and make it to expand, and topping up passage 15 functions are that filling liquid enters bladder.
