Make the stay tube break away from the scope as required, only need to put down the gas in the annular inner bag, the scope is not being extruded in the annular inner bag shrink to can easily take out the scope from the stay tube, then carry out other operations. When the device of the invention needs to be taken out of a human body, the device can be sleeved at the front end of an endoscope and taken out along with the endoscope, or the whole device can be taken out by pulling an inflation tube or an inner bag inflation tube.
The annular inner bag can be selectively arranged in the embodiment, the purpose of the embodiment is to ensure that the endoscope is uniformly pressed and does not incline, and meanwhile, the annular inner bag is adopted, so that the fixation is more stable after the inflation. This embodiment adopts the gasbag to lift up pathological change tissue, simple structure, convenient operation.
When the device is pulled through the inflation tube and taken out of a human body, in order to enhance the strength of the whole inflation tube and better pull the device, a guide wire 7 is further arranged in the inflation tube, the front end of the guide wire is connected with the side wall of the supporting tube, and the tail end of the guide wire is positioned at the tail end of the inflation tube or extends out of the tail end of the inflation tube. The design of the guide wire can improve the hardness of the inflation tube, and the support tube can be smoothly taken out of a human body when the inflation tube is pulled. When the guide wire extends out of the inflation tube, a sealing plug is required to be arranged at the end part of the inflation tube, a through hole for the guide wire to pass through is formed in the sealing plug, and the sealing plug can be made of rubber and has certain flexibility, so that the sealing effect is better, and gas leakage is avoided.
In order to stably draw, the front end of the guide wire is annular, and an annular groove 8 for accommodating the front end of the guide wire is formed in the outer side wall of the supporting tube. Adopt the annular setting can with the pot head of seal wire at the stay tube outer wall, fixed more firm, more conveniently pull out the human body through the seal wire with whole device.
In order to make the annular inner bag more stable after being inflated, the inner side wall of the supporting tube is provided with an annular groove 9 for accommodating the outer side wall of the annular inner bag. The annular groove is adopted, the annular inner bag can be clamped, and the phenomenon that the inner bag is displaced or deformed in the extrusion process to influence the stability of fixation between the endoscope and the supporting tube is avoided.
In order to facilitate the control of inflation and deflation, the front end of the inflation tube is communicated with the air bag, and the tail end of the inflation tube is provided with an inflation/deflation tube orifice 10. The front end of the inner bag inflation tube is communicated with the annular inner bag, the tail end of the inner bag inflation tube penetrates through the side wall of the supporting tube from inside to outside, and the side wall of the inner bag inflation tube positioned on the outer wall of the supporting tube is attached to the side wall of the inflation tube; the tail end of the inner bag inflation tube is provided with an inflation and deflation interface 11. And the air charging and discharging port and the air charging and discharging pipe port are respectively provided with a valve 12. By adopting the design, the inflation tube and the inner bag inflation tube are attached, so that the inflation tube and the inner bag inflation tube can be integrated into a whole, the human body can be conveniently entered and exited, and the operation of medical care personnel can be facilitated. The valve is arranged to easily realize opening and closing, so that air leakage or accidental inflation of the air bag or the annular inner bag is avoided.
It should be noted that the inner bag inflation tube and the inflation tube may not be attached together, but may be separated (a gap exists between the two), and the adjustment may be performed according to actual conditions. In addition, in order to enable the guide wire to extend out of the end part of the inflation tube, the opening of the inflation and deflation tube is arranged on the side wall of the inflation tube, so that the guide wire and the valve can be perfectly staggered, and the functions cannot be influenced mutually.
Furthermore, the leading-in pipe is of a hollow round table structure, and one end with a larger diameter is connected with the supporting pipe; the supporting tube is of a hollow cylindrical structure; the support tube is connected to the lead-in tube by a transition tube 14, which is a hollow round table structure with the larger diameter end connected to the support tube and the smaller diameter end connected to the lead-in tube. Adopt above-mentioned design, because the leading-in pipe front end mouth footpath is less can be more convenient insert pathological change tissue and normal tissue between the clearance in, then through the increase of the depth of insertion, the transition pipe with leading-in get into gradually and lift up partly with pathological change tissue between pathological change tissue and the normal tissue, inflate through the gasbag afterwards and lift up completely, step by step, convenient operation safety.
Specifically, the introducing pipe, the transition pipe and the supporting pipe are all made of transparent materials; the leading-in pipe, the transition pipe and the supporting pipe are of an integrated structure. Adopt integrative design can ensure auxiliary device's stability and fastness, adopt transparent design can make things convenient for the scope to observe the internal condition of human body, avoid auxiliary device to block scope sight.
Example 2
As shown in fig. 4, the present embodiment is different from embodiment 1 in that two annular inner bags are provided in the support tube, and the two annular inner bags are inflated by one inner bag inflation tube; the arrangement of the two annular inner bags can further ensure that the endoscope cannot incline or be unstable in the supporting tube, so that the device can be firmly fixed at the front end of the endoscope.
Example 3
As shown in fig. 5 to 8, the present embodiment is different from embodiment 1 in that a second guide wire 13 is further provided in the inner balloon inflation tube of the present embodiment; the front end of the second guide wire is connected with the side wall of the supporting tube, and the tail end of the second guide wire is positioned at the tail end of the inner balloon inflation tube or extends out of the tail end of the inner balloon inflation tube;
or the front end of the second guide wire is positioned in the annular inner bag, and the tail end of the second guide wire is positioned at the tail end of the inner bag inflation tube or extends out of the tail end of the inner bag inflation tube.
This embodiment adopts and sets up the second seal wire in interior bag gas tube, can strengthen the intensity of interior bag gas tube, sets up interior bag gas tube at the opposite side of stay tube simultaneously, can realize the stay tube both sides and stimulate simultaneously like this, can make the stay tube more stable from human in being pulled out.
It is worth to say that the tail end of the inner bag inflation tube is also provided with a rubber sealing plug for sealing the end part of the inner bag inflation tube, and meanwhile, the second guide wire can conveniently extend out of the rubber sealing plug, so that air leakage can be avoided.
