DETAILED DESCRIPTION
[0013] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.
[0014] The present embodiment provides a gastrointestinal surgical anal dilator, comprising an anal front end tube 1, a stable rear end tube 2, a middle frame 4 and an inner cavity air chamber 6, wherein the middle frame 4 is arranged between the anal front end tube 1 and the stable rear end tube 2, and the inner cavity air chamber 6 is arranged on one side of the stable rear end tube 2; The inner wall of the anus is slowly expanded and the inner wall of the anus is covered with a support unit. The inner wall of the anus is slowly expanded and the inner wall of the anus is covered with a support unit arranged on the surface of the front end tube 1 for entering the anus and the rear end tube 2 for stabilizing the anus. The support unit is used for synchronously supporting and expanding the inner wall of the anus when the anus is expanded, so as to reduce the squeezing of a single area of the anus.
[0015] The inner wall of the anus slowly expands. The inner wall covering support unit of the anus includes a front end expansion part, which includes a front end buffer gasket 11. The front end buffer gasket 11 is sleeved on the surface of the front end tube 1 for entering the anus. The two ends of the surface of the front end buffer gasket 11 are respectively sleeved with a front end limiting rubber ring 12 and a front end limiting rubber ring 2 13. A front end expansion airbag 14 is arranged between the front end limiting rubber ring 12 and the front end limiting rubber ring 2 13. The front end expansion airbag 14 is arranged in a ring shape and is sleeved and installed on the surface of the front end tube 1 for entering the anus.
[0016] The inner wall of the anus slowly expands and the inner wall covering support unit of the anus also includes a middle anti-slip portion, which includes a middle expansion airbag 5. The middle expansion airbag 5 is arranged in a ring shape and covers the surface of several groups of middle skeletons 4.
[0017] The inner wall of the anus slowly expands. The inner wall covering support unit of the anus also includes a rear end stabilizing part, which includes a rear end buffer gasket 21. The rear end buffer gasket 21 is sleeved on the surface of the stabilizing rear end tube 2. The two ends of the surface of the rear end buffer gasket 21 are respectively sleeved with a rear end limiting rubber ring 1 22 and a rear end limiting rubber ring 2 23. A rear end expansion airbag 24 is arranged between the rear end limiting rubber ring 1 22 and the rear end limiting rubber ring 2 23. The rear end expansion airbag 24 is arranged in a ring shape, and the rear end expansion airbag 24 is sleeved and installed on the surface of the stabilizing rear end tube 2.
[0018] A rear air intake valve 231 is provided on the surface of the rear end limiting rubber ring 23 , and the rear end air intake valve 231 is communicated with the rear end expansion air bag 24 .
[0019] A front end notch 15 is provided on the side of the anus-entering front end tube 1 close to the stable rear end tube 2 , and a rear end notch 25 is provided on the side of the stable rear end tube 2 close to the anus-entering front end tube 1 .
[0020] In this embodiment, when the gastroscope is inserted for examination, the front end of the gastroscope will be slowly inserted from the patient's anus area. In order to reduce the feeling of foreign body insertion in the patient's anus area during the insertion of the gastroscope, the operator can slowly infuse gas into the middle-end air inlet pipe 28 through the middle-end air inlet valve 27 in the installation hole 26 area. The gas enters the middle-end expansion balloon 5 through the middle-end air inlet pipe 28, and the middle-end expansion balloon 5 slowly inflates. After the middle-end expansion balloon 5 is inflated, the middle-end expansion balloon 5 will fit tightly against the inner wall of the patient's anus to ensure that the anal dilator does not fall off. The middle-end expansion balloon 5 will regionally expand the patient's inner anus, so that the middle-end area of the patient's anus is effectively expanded, effectively reducing the feeling of foreign body insertion in the patient's anus area. Example
[0021] Based on Example 1, when the gastrointestinal surgery department uses a colonoscopy to examine the patient's internal intestines, the colonoscope will be inserted into the patient's intestines through the patient's anal area to perform an intestinal examination. During the colonoscope insertion process, the end of the colonoscope will continue to go deeper. In order to prevent the end of the colonoscope from bringing the anal dilator completely into the patient's anus and to ensure the long-term expansion of the patient's anal area, a balloon expansion medium filling unit is provided in this embodiment to avoid the above-mentioned problem.
[0022] The middle frame 4 region is provided with a bladder expansion medium filling unit.
[0023] The bladder expansion medium filling unit includes a front end air inlet part, which includes a front end air inlet pipe 42. An installation cavity 41 is provided on the surface of the central skeleton 4. The front end air inlet pipe 42 is installed inside the installation cavity 41. The front end air inlet pipe 42 is connected to the inner cavity air chamber 6. A front end air inlet valve 61 is embedded in the surface of the inner cavity air chamber 6.
[0024] The two ends of the central frame 4 are respectively inserted into the front end notch 15 and the rear end notch 25 , and one end of the front end air inlet pipe 42 is communicated with the front end expansion airbag 14 .
[0025] The balloon expansion medium filling unit includes a middle-end air inlet part, which includes a middle-end air inlet pipe 28. A mounting hole 26 is provided on the surface of the stable rear end tube 2. The middle-end air inlet pipe 28 is installed inside the mounting hole 26. A middle-end air inlet valve 27 is installed at one end of the middle-end air inlet pipe 28, and the other end of the middle-end air inlet pipe 28 is connected to the middle-end expansion airbag 5.
[0026] In this embodiment, when the rear end expansion balloon 24 is fully inflated, the rear end expansion balloon 24 will form an annular cover. When the anal dilator shakes, the air-filled rear end expansion balloon 24 will press against the outside of the anal anus. Since the surface of the rear end expansion balloon 24 is relatively soft, the contact stimulation of the patient's anal area can be reduced. At the same time, the rear end expansion balloon 24 will be blocked on the outside of the patient's anus after being filled with gas. The rear end expansion balloon 24 will prevent the stable rear end tube 2 from sliding into the patient's anus, thereby further ensuring the stable insertion effect of the gastroscope.
[0027] Working principle: During the use of the present application, the medical staff applies a lubricating medium to the surface of the front end tube 1 of the anal dilator, and then the medical staff massages the patient's anal area for relief, and slowly inserts the front end tube 1 into the inner wall of the patient's anus. When the front end tube 1 is completely immersed in the patient's anus, as the anal dilation step continues, the middle frame 4 and the middle end expansion balloon 5 will also be immersed in the patient's anus, and the stable rear end tube 2 will stay at the outer end of the patient's anus. The operator can slowly insert the colonoscope into the patient's anus through the stable rear end tube 2 and the front end tube 1 to ensure that the patient undergoes a gastrointestinal endoscopic examination; When the gastroscope is inserted for examination, the front end of the gastroscope will be slowly inserted from the anus area of the patient. During the insertion of the gastroscope, in order to reduce the feeling of foreign body insertion in the anus area of the patient, the operator can slowly infuse gas into the middle-end air inlet pipe 28 through the middle-end air inlet valve 27 in the installation hole 26 area. The gas enters the middle-end expansion balloon 5 through the middle-end air inlet pipe 28, and the middle-end expansion balloon 5 is slowly inflated. After the middle-end expansion balloon 5 is inflated, the middle-end expansion balloon 5 will fit tightly against the inner wall of the patient's anus to ensure that the anal dilator does not fall off. The middle-end expansion balloon 5 will regionally expand the patient's inner anus, so that the middle-end area of the patient's anus is effectively expanded, effectively reducing the feeling of foreign body insertion in the patient's anus area. As the gastroscope is continuously inserted, in order to reduce the insertion stimulation of the front end of the gastroscope to the intestinal area of the patient, the operator can infuse gas into the inner cavity gas chamber 6 area through the front end air inlet valve 61 on the surface of the inner cavity gas chamber 6, and the gas inside the inner cavity gas chamber 6 is slowly infused into the front end expansion balloon 14 through the front end air inlet pipe 42. The front end expansion balloon 14 is restricted by the front end limiting rubber ring 12 and the front end limiting rubber ring 2 13 during the expansion process, so that the front end expansion balloon 14 can only expand outward in the area between the front end limiting rubber ring 12 and the front end limiting rubber ring 2 13, thereby reducing the contact area between the front end expansion balloon 14 and the inner side of the patient's anus, reducing the sense of support for the area connecting the inner side of the patient's anus and the intestine, while ensuring the support and expansion of this area, ensuring the insertion effect of the gastroscope, and further reducing the sense of foreign body insertion in the patient's anus area; During the insertion process, the gastroscope continuously penetrates into the patient's anus and enters the patient's intestines through the anus. During the insertion process of the gastroscope, in order to ensure that the anal dilator continues to remain in the patient's anal area and reduce the stimulation to the outside of the patient's anus caused by the activity of the anal dilator area, the medical staff can fill the rear end expansion balloon 24 with gas through the rear end air inlet valve 231. After the rear end expansion balloon 24 area is inflated, it expands outward along the restricted area of the rear end restriction rubber ring 1 22 and the rear end restriction rubber ring 2 23. When the rear end expansion balloon 24 is fully inflated, the rear end expansion balloon 24 will form an annular covering. When the anal dilator shakes, the inflated rear end expansion balloon 24 will press against the outside of the anal anus. Since the surface of the rear end expansion balloon 24 is relatively soft, the contact stimulation of the patient's anal area can be reduced. At the same time, the rear end expansion balloon 24 will be blocked on the outside of the patient's anus after being filled with gas. The rear end expansion balloon 24 will prevent the stable rear end tube 2 from sliding into the patient's anus, further ensuring the stable insertion effect of the gastroscope.
[0028] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
