[0019] Compared with the prior art, this application has the following beneficial effects:

[0020] The present application includes a pumping module and a water pipe, wherein the water pipe is divided into a plurality of independent liquid flow channels; an adjusting box is provided at one end of the water pipe along the axial direction of the water pipe, and the inlet end of the adjusting box is connected to the pumping module; the adjusting box is provided with a plurality of drainage holes, each of which is respectively connected to each of the liquid flow channels; a plurality of adjusting rods are slidably provided on the adjusting box, one end of each adjusting rod extending outside the adjusting box and the other end extending into each of the drainage holes to control the on / off state of the drainage holes; and a housing is also connected to the outlet end of the water pipe, and a plurality of water storage bags are provided on the housing, each of which is respectively connected to each of the liquid flow channels;

Since the drainage hole is blocked by the regulating rod, the regulating box is in a state of pressure buildup. When the water storage bag needs to be filled with water, the regulating rod corresponding to the water storage bag to be flushed is pulled outward. The regulating rod will gradually separate from the drainage hole while being pulled outward, thereby opening the drainage hole.

[0024] Secondly, the present application can place the hot water heating device and other auxiliary equipment externally. It is only necessary to send the water pipe and the water storage bag at the front end into the human stomach, thereby simplifying the structure of the equipment to the greatest extent and reducing the size of the equipment, making it easier to cooperate with endoscopic equipment and meet various surgical requirements.

[0025] Finally, when this application is used, the water supply module can realize the automatic input and extraction of hot water. Medical staff only need to control the working status of the system by controlling the adjustment lever, thereby simplifying the operation process of the gastric mucosal damage device as much as possible.

[0038] Example 1:

[0039] Reference Figures 1 to 6 This embodiment, as an optional embodiment of the present application, discloses a gastric mucosal damage device through an endoscopic channel, comprising a pumping module and a water delivery pipe 1, wherein the pumping module comprises a peristaltic pump 8, and the present application also comprises a hot water tank and a heating device provided on the hot water tank; the inlet end of the peristaltic pump 8 is connected to the hot water tank, thereby providing hot water for the entire device;

[0040] The water pipe 1 is a medical hose. Several partition plates 10 are disposed within the pipe 1 along its axis. Each partition plate 10 is connected to the inner wall of the pipe 1 at one end and converges at the axis of the pipe 1 at its other end in the radial direction of the pipe 1. In other words, the partition plates 10 are arranged radially on a radial cross-section of the pipe 1, thereby dividing the inner cavity of the pipe 1 into a plurality of independent liquid flow channels 2.

[0041] The above segmentation method is simple and can ensure the effectiveness of isolation. At the same time, the above method can also integrate several pipelines into one, which not only realizes the one-time transportation of several pipelines, but also avoids safety accidents caused by the separation of pipelines.

[0042] The gastric mucosal damage device further includes an adjustment box 3, which includes an upper box body 301 and a lower box body 302. The upper box body 301 is plugged and connected to the lower box body 302. In order to improve the tightness of the connection, flange plates can be further provided on the upper box body 301 and the lower box body 302, and bolts and sealing gaskets are connected between the flange plates.

[0043] A water inlet pipe 9 is provided at the top of the upper box body 301, and the water inlet pipe 9 is connected to the water outlet pipe of the peristaltic pump 8; a cavity for temporarily storing hot water is provided on both the upper box body 301 and the lower box body 302. The two cavities are spliced ​​together to form a closed cavity after the upper box body 301 and the lower box body 302 are spliced ​​together, and the water inlet pipe 9 is connected to the cavity;

[0044] A plug-in groove is provided on the bottom surface of the lower box body 302, and the plug-in groove is adapted to the cross-section of the water pipe 1, so that the connection between the lower box body 302 and the water pipe 1 is achieved by plugging. It should be pointed out that in order to ensure the stability of the connection, after the plug-in is completed, the stability and reliability of the connection can be further improved by adding a clamp.

[0045] Furthermore, adhesive may be provided in the above-mentioned plug-in slot, so as to realize the connection between the lower box body 302 and the water pipe 1 by bonding;

[0046] A plurality of drainage holes 4 are provided on the bottom surface of the lower box body 302. The number of the drainage holes 4 is the same as the number of the liquid flow channels, and each drainage hole 4 corresponds to each liquid flow channel one by one, that is, each liquid flow channel 2 is connected to the cavity on the regulating box 3 through each drainage hole 4.

[0047] Furthermore, a plurality of adjustment holes 303 are provided on the upper box body 301, and each of the adjustment holes 303 is coaxial with each of the drainage holes 4;

[0048] The regulating hole 303 includes a first blocking hole 3031, a connecting hole 3032, and a second blocking hole 3033 that are coaxially connected in sequence; the inner diameter of the first blocking hole 3031 is 1.5-2 times the inner diameter of the connecting hole 3032, and the inner diameter of the second blocking hole 3033 is 1.5-2 times the inner diameter of the connecting hole 3032;

[0049] It should be noted that the inner diameter of the first blocking hole 3031 and the inner diameter of the second blocking hole 3033 can be the same or different, but both must be larger than the inner diameter of the connecting hole 3032, so as to ensure that the cross-section of the adjustment hole 303 is an I-shaped structure as a whole;

[0050] Furthermore, a plurality of adjusting rods 5 are slidably provided in the adjusting box 3. The adjusting rods 5 include a main rod body 501. Along the axis direction of the adjusting rods 5, one end of the adjusting rods 5 is provided with a blocking block 502 adapted to the drainage hole 4. That is, the blocking block 502 completely closes the drainage hole 4.

[0051] The other end of the regulating rod 5 passes through the regulating hole 303 and extends outside the regulating box 3 , and a regulating valve core 503 adapted to the regulating hole 303 is further provided at a section of the regulating rod 5 located in the regulating hole 303 ;

[0052] The regulating valve core 503 includes a first blocking plate 5031, a connecting rod 5032, and a second blocking plate 5033, which are connected in sequence. The first blocking plate 5031 is adapted to the first blocking hole 3031, and the second blocking plate 5033 is adapted to the second blocking plate 5033. The length of the connecting rod 5032 is 1.5-2 times the length of the connecting hole 3032.

[0053] It should be noted that the first blocking plate 5031 is integrally connected to the connecting rod 5032, and the second blocking plate 5033 is threadedly connected to the connecting rod 5032; alternatively, the first blocking plate 5031 is threadedly connected to the connecting rod 5032, and the connecting rod 5032 is integrally connected to the second blocking plate 5033;

[0054] After assembly is completed, the first blocking plate 5031 is inserted into the first blocking hole 3031 to completely seal it. At this time, since the length of the connecting rod 5032 is 1.5-2 times the length of the connecting hole 3032, the second blocking plate 5033 is separated from the second blocking hole 3033.

[0055] By controlling the length of the connecting rod 5032, it is ensured that at the same time, only one of the first blocking plate 5031 and the second blocking plate 5033 can be plugged and connected to the adjustment hole 303. That is, because the length of the connecting rod 5032 is greater than the length of the connecting hole 3032, after the first blocking plate 5031 is fully inserted into the first blocking hole 3031, the second blocking plate 5033 and the second blocking hole 3033 will inevitably be separated. Conversely, the first blocking plate 5031 and the first blocking hole 3031 will also inevitably be separated.

[0056] On the other hand, by controlling the length of the connecting rod 5032 to be 1.5-2 times the length of the connecting hole 3032, the maximum distance between the first blocking plate 5031, the second blocking plate 5033, and the upper box body 301 can be controlled, so that during the control process, the second blocking plate 5033 can be quickly and accurately docked with the second blocking hole 3033, thereby preventing hot water from leaking from the regulating hole 303.

[0057] Furthermore, a sealing groove 11 is provided on the outer circumference of each of the first sealing plate 5031 and the second sealing plate 5033, and a sealing ring 12 is provided in the sealing groove 11. The sealing ring 12 can effectively improve the tightness of the connection between the first sealing plate 5031 and the first sealing hole 3031, and between the second sealing plate 5033 and the second sealing hole 3033, thereby preventing hot water leakage.

[0058] Furthermore, a guide surface 13 with a conical structure is provided at the inlet end of the second blocking hole 3033 , and a thrust surface 14 adapted to the guide surface 13 is provided on the second blocking plate 5033 ;

[0059] On the one hand, the setting of the guide surface 13 can enable the second sealing plate 5033 to be quickly and accurately docked with the second sealing hole 3033, thereby ensuring the rapid switching of the sealing state of the adjustment hole 303; on the other hand, along the pulling-out direction of the adjustment rod 5, the second sealing plate 5033 is inserted into the second sealing hole 3033 from the bottom upward, and the guide surface 13 of the conical structure can fit more closely with the thrust surface 14 under the action of hot water pressure, and the greater the pressure, the tighter the fit, thereby improving the sealing effect of the second sealing plate 5033 on the adjustment hole 303.

[0060] Finally, the guide surface 13 has a conical structure. The setting of the guide surface 13 effectively increases the contact area between the second blocking plate 5033 and the second blocking hole 3033, which is conducive to improving the sealing performance.

[0061] The gastric mucosal damage device also includes a housing 6, which is made entirely of hard plastic. A plug-in slot is provided on the top surface of the housing 6, which is adapted to the water outlet end of the water pipe 1 and connects the housing 6 to the water pipe 1 by plugging. The plug-in slot is also filled with adhesive.

[0062] The housing 6 is provided with a plurality of independent filling chambers 15 separated from each other. A plug-in tube 16 is provided in each filling chamber 15. Each water storage bag 7 is connected to the outlet end of each plug-in tube 16. The inlet end of each plug-in tube 16 is connected to each liquid flow channel 2.

[0063] The outer surface of the housing 6 is further provided with an inlet and outlet 17 , each of the inlet and outlet 17 is connected to each of the filling chambers 15 ;

[0064] During use, when hot water is added to the water storage bag, it will expand rapidly and fill the entire isolation chamber. Subsequently, part of the water storage bag will extend from the inlet and outlet and contact the gastric mucosa, thereby scalding the gastric mucosa.

[0065] During use, the human body is first intubated with an endoscope, and then the gastric mucosal damaging device described in the present application is introduced into the stomach through the inner diameter channel, wherein the regulating box is outside the human body; then, hot water is delivered into the regulating box through the pumping module. Since the drainage hole is blocked by the regulating rod, the regulating box is in a state of pressure buildup. When the water storage bag needs to be filled with water, the regulating rod corresponding to the water storage bag to be flushed is pulled outward. The regulating rod will gradually separate from the drainage hole while being pulled outward, thereby opening the drainage hole. At this time, the hot water in the regulating box will enter the water storage bag through the water delivery pipe. The water storage bag will expand when filled with water, thereby contacting the gastric mucosa, thereby achieving a scalding operation on the gastric mucosa;

[0066] When the scalding is completed, the hot water in the water storage bag can be quickly extracted by reverse pumping of water by the pumping module, thereby avoiding excessive scalding. At the same time, the isolation of the water storage bag can also prevent the gastric juice from being extracted;

[0067] Compared with the existing technology, the present application uses hot water as a heat source, and drives the expansion of the expansion water storage bag by hot water, thereby achieving control of the size of the wound surface. Compared with devices such as temporary heating by electric heating wires, on the one hand, the present application uses hot water as a heat source, which not only has better temperature stability, avoiding excessive burns to the gastric mucosa caused by drastic temperature fluctuations, but also the input hot water has reached the appropriate scalding temperature, eliminating the heating waiting time and improving the efficiency of gastric mucosal burns; on the other hand, the present application can simultaneously deliver multiple expansion water storage bags to the stomach, and medical staff can choose to use one or more expansion water storage bags as needed, which is beneficial to improving the efficiency of gastric burn surgery, avoiding the expansion of gastric mucosal wounds, and facilitating postoperative recovery;

[0068] Secondly, the present application can place the hot water heating device and other auxiliary equipment externally. It is only necessary to send the water pipe and the water storage bag at the front end into the human stomach, thereby simplifying the structure of the equipment to the greatest extent and reducing the size of the equipment, making it easier to cooperate with endoscopic equipment and meet various surgical requirements.

[0069] Finally, when this application is used, the water supply module can realize the automatic input and extraction of hot water. Medical staff only need to control the working status of the system by controlling the adjustment lever, thereby simplifying the operation process of the gastric mucosal damage device as much as possible. While improving the accuracy of the operation, it can also improve the efficiency of the gastric mucosal burn operation, which is conducive to controlling the wound surface and improving the postoperative recovery effect.

[0070] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
