[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 of the drainage holes 4 corresponds to each of the liquid flow channels one by one, that is, each of the liquid flow channels 2 is connected to the cavity on the regulating box 3 through each of the drainage holes 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 comprises a first blocking hole 3031, a connecting hole 3032 and a second blocking hole 3033 which 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 regulating hole 303 is an I-shaped structure as a whole;

[0050] Furthermore, a plurality of adjusting rods 5 are slidably arranged in the adjusting box 3, and 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 drain hole 4, that is, the blocking block 502 completely closes the drain hole 4.

[0060] Finally, the guide surface 13 is a conical structure, and 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;

[0064] When in 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] When in use, firstly, the human body is intubated with an endoscope, and then the gastric mucosal damager 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 transported into the regulating box through the pumping module, and since the drainage hole is blocked by the regulating rod, the regulating box is in a state of pressure holding at this time, and when it is necessary to fill the water storage bag with water, the regulating rod corresponding to the water storage bag to be flushed is pulled outward, and the regulating rod will gradually separate from the drainage hole while being pulled outward, thereby opening the drainage hole, and at this time, the hot water in the regulating box will enter the water storage bag through the water delivery pipe, and the water storage bag will expand in the water-filled state, 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 gastric juice can be prevented from being extracted through the isolation of the water storage bag;

[0067] Compared with the prior art, the present application uses hot water as a heat source, and drives the expansion of the expansion water storage bag by hot water, thereby realizing the control of the wound size. 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 of the gastric mucosa caused by drastic temperature fluctuations, but also the input hot water has reached a suitable scalding temperature, saving 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 according to needs, which is beneficial to improving the efficiency of gastric scalding 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 only needs 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 the present 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 state 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.
