[0020] Compared with the prior art, this application has the following beneficial effects:

[0021] The present application includes a flexible guide tube, a fixed plate is provided in the flexible guide tube, and a sliding frame is also slidably provided in the flexible guide tube, and along the extension direction of the sliding frame, the sliding frame is located at the front end of the fixed plate, and a water storage chamber is formed between the fixed plate and the sliding frame; the outlet end of the flexible guide tube is also provided with a limiting ring adapted to the sliding frame; the scalding device also includes a water delivery module, the inlet end of the water delivery module is connected to an external water source, and the outlet end thereof passes through the fixed plate and communicates with the water storage chamber; at the same time, a plurality of expansion water storage bags are also provided on the sliding frame, each of the expansion water storage bags is respectively communicated with the water storage chamber, and a plurality of adjustment components are further provided in the water storage chamber for adjusting the on-off state of each expansion water storage bag and the water storage chamber; each of the adjustment components is provided with a pulling cable extending beyond the flexible guide tube;

[0022] During use, the flexible guide tube enters the stomach through the mouth and esophagus, and then delivers hot water to the water outlet cavity through the water delivery module. Due to the use of water pressure, the sliding frame will gradually extend and eventually fit with the limit ring to reach the end position of the stroke;

[0023] Then, the expansion water storage bag that needs to be filled with water for expansion is selected from each expansion water storage bag, and the corresponding pulling cable is pulled to open the water transmission channel between the expansion water storage bag and the water storage cavity, so that the hot water temporarily stored in the water storage cavity enters the expansion water storage bag, thereby rapidly expanding the expansion water storage bag, and finally the gastric mucosa is scalded by the expanded expansion water storage bag;

Compared with the existing 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.

[0026] Secondly, compared with the method of temporary heating through a heating device, the present application can place the hot water heating device externally and set a water pipe in the flexible guide tube. It not only removes the heating device from the flexible guide tube, but also removes the temperature monitoring device, thereby maximally simplifying the internal structure of the flexible guide tube, which is conducive to improving the stability and reliability of the equipment.

[0027] Finally, when the present application is used, the water supply module can realize the automatic input and extraction of hot water, and the medical staff only needs to control the working status of the system by pulling the cable; at the same time, all the equipment are hidden in the flexible guide tube, and all the devices can be quickly and safely placed into the stomach through the intubation operation of the flexible guide tube, and the working status of the equipment can be controlled by pulling the cable, 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 beneficial to control the wound surface and improve the postoperative recovery effect.

When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0040] Example 1

[0041] Reference Figures 1 to 6This embodiment discloses an oral gastric mucosal damage device, including a flexible guide tube 1. The flexible guide tube 1 is preferably a commonly used medical PVC tube. It should be noted that the flexible guide tube 1 includes a catheter body and a protective shell that are connected in one piece. The catheter body is a flexible hose. The protective shell is provided at the front end of the catheter body (the end directly inserted into the stomach). The protective shell needs to be a medical hard tube, such as a hard PVC tube.

[0042] The flexible guide tube 1 of the above structure can ensure the flexibility of the entire device, thereby meeting the requirements of intubation; on the other hand, the front hard tube structure can ensure that it has a certain hardness, thereby reducing the difficulty of passing through the gastric cardia; and the hard shell can also ensure the airtightness of the connection between the various components, avoiding hot water leakage caused by pipe bending, and improving the reliability and stability of the entire device.

[0043] A fixed plate 2 is further provided within the protective shell of the flexible guide tube 1, and the fixed plate 2 is tightly connected to the protective shell. A sliding frame 3 is also slidably provided within the protective shell. Along the extension direction of the sliding frame 3, the sliding frame 3 is located at the front end of the fixed plate 2. Between the fixed plate 2 and the sliding frame 3 is a water storage chamber 4 for temporarily storing hot water.

[0044] A limiting ring 5 is further provided at the outlet end of the protective shell. Along the axial direction of the protective shell, the limiting ring 5 limits the position of the sliding frame 3 by abutting against the sliding frame 3, thereby preventing the sliding frame 3 from separating from the protective shell.

[0045] It should also be noted that a protective surface with an arc-shaped structure is provided at the front end of the protective shell to prevent the edge of the protective shell from being too sharp and causing scratches on the gastric mucosa;

[0046] Furthermore, the sliding frame 3 includes a slider 301 and a limiting frame 302. Along the axial direction of the protective shell, the bottom surface of the slider 301 is integrally connected to the top surface of the limiting frame 302. It should be noted that the outer peripheral surface of the slider 301 is in contact with the inner wall of the protective shell, and the outer diameter of the limiting frame 302 is smaller than the outer diameter of the slider 301, thereby ensuring that the limiting frame 302 can extend from the limiting ring 5 to the outside of the flexible limiting ring 5;

[0047] The limiting frame 302 is further provided with a plurality of temporary storage chambers 303, which are evenly arranged on the outer circumference of the limiting frame 302 around the axis of the limiting frame 302. Each temporary storage chamber 303 is provided with an expansion water storage bag 6. At the same time, the outer circumference of the limiting frame 302 is further provided with a plurality of expansion ports 304, each of which is connected to a respective temporary storage chamber 303.

[0048] The slider 301 is further provided with a plurality of connecting tubes 305 , one end of each connecting tube 305 passing through the slider 301 and communicating with the water storage chamber 4 , and the other end thereof being connected to the expansion water storage bag 6 , thereby connecting the expansion water storage bag 6 with the water storage chamber 4 through the connecting tube 305 ;

[0049] During operation, the expanded water storage bag 6 can only extend from the expansion opening 304, thereby limiting the expansion direction of the expandable water storage bag 6, which is beneficial to controlling the location of the burn wound. At the same time, the shape of the extended portion of the expandable water storage bag 6 can be controlled, which is beneficial to controlling the size of the burn wound.

[0050] It should be pointed out that in order to ensure the expandability and structural stability of the expandable water storage bag 6, the expandable water storage bag 6 is preferably made of natural rubber or silicone, and its structure is similar to that of a balloon. When not in operation, it is in a contracted state. When filled with water, its volume can quickly expand by 5-10 times, or even more times.

[0051] Furthermore, a plurality of adjustment components are provided in the water storage chamber 4. It should be noted that the number of the adjustment components is the same as the number of the expansion water storage bags 6, and each of the adjustment components corresponds to each of the connecting pipes 305.

[0052] The adjustment assembly includes a sealing plug 8, a pull cord 9, and a switching module. The sealing plug 8 is inserted into the inlet end of the connecting tube 305, thereby cutting off the connection channel between the expansion water storage bag 6 and the water storage chamber 4. The switching module includes a first sealing plate 11 and a second sealing plate 12. The first sealing plate 11 and the second sealing plate 12 are connected by a connecting rod 13. It should be noted that the outer diameter of the connecting rod 13 is 0.3-0.5 times the outer diameter of the first sealing plate 11 and the second sealing plate 12. That is, the switching module as a whole has an I-shaped structure.

[0053] The first sealing plate 11 is integrally connected to the connecting rod 13, and the second sealing plate 12 is threadedly connected to the connecting rod 13; the detachable structure of the connecting rod 13 and the second sealing plate 12 enables rapid installation and removal of the switching module;

[0054] The fixing plate 2 is further provided with a plurality of adjustment holes 10. Along the axial direction of the fixing plate 2, one end of each adjustment hole 10 is provided with a first stepped hole 14, and the other end thereof is provided with a second stepped hole 15, wherein the first stepped hole 14 is adapted to the first sealing plate 11, and the second stepped hole 15 is adapted to the second sealing ring, that is, the first stepped hole 14, the adjustment hole 10 and the second stepped hole 15 are coaxially connected in series in an I-shaped structure;

[0055] At the same time, the length of the connecting rod 13 is 1.5-2 times the length of the adjusting hole 10;

[0056] By controlling the length of the connecting rod 13, it is possible to ensure that only one of the first sealing plate 11 and the second sealing plate 12 can be plugged into and connected to the adjustment hole 10 at the same time. That is, because the length of the connecting rod 13 is greater than the length of the adjustment hole 10, after the first sealing plate 11 is fully inserted into the first stepped hole 14, the second sealing plate 12 and the second stepped hole 15 are inevitably separated, and vice versa. On the other hand, by controlling the length of the connecting rod 13 to 1.5-2 times the length of the adjustment hole 10, the maximum distance between the first sealing plate 11 and the second sealing plate 12 and the fixed plate 2 can be controlled, so that during the control process, the second sealing plate 12 can be quickly and accurately connected to the second stepped hole 15, thereby preventing hot water from leaking from the adjustment hole 10.

[0057] The bottom surface of the second sealing plate 12 is connected to the sealing plug 8 via a pull rope 9. A pulling cable 7 is also provided on the first sealing plate 11. The free end of the pulling cable 7 extends outside the flexible guide tube 1 to facilitate medical staff to pull the pulling cable 7.

[0058] Furthermore, a marking icon is provided at one end of each pulling cable 7 located outside the gastric mucosal damage device, thereby helping medical personnel to quickly and accurately locate the pulling cable 7 to be used, thereby improving the convenience of using the device;

[0059] At the same time, a color ribbon can be filled on the flexible guide tube 1, and the position of the color ribbon is opposite to the expansion port 304, so as to mark the expansion buckle, helping medical staff to quickly and accurately rotate and adjust the position of each expansion port 304, thereby improving the positioning accuracy of the burn wound.

[0060] Furthermore, a number of guide wheels or guide heads can be set in the flexible guide tube 1, and each pulling cable 7 passes through the corresponding guide wheel or guide head and leads out of the flexible guide tube 1; it can realize the separation of each pulling cable 7, and avoid the pulling cables 7 from being entangled with each other and interfering with each other.

[0061] It should be noted that the length of the drawstring 9 is limited. That is, when the sliding frame 3 and the limiting ring 5 are pressed against each other, the drawstring 9 is in a stretched state. However, the stretched state of the drawstring 9 cannot affect the sealing state of the sealing plug 8.

[0062] During use, the sealing plug blocks the inlet end of the expansion water storage bag 6, and the first sealing plate 11 also blocks the first step hole 14. When the sliding frame 3 moves to the bottom, the medical staff pulls one or more pulling cables 7 as needed. In the process of pulling the pulling cables 7, the first sealing ring gradually disengages from the first step hole 14, and the second sealing plate 12 gradually enters the second step hole 15, thereby replacing the first sealing plate 11 to achieve the blockage of the adjustment hole 10. At the same time, in the process of pulling the pulling cables 7, the second sealing plate 12 will pull the sealing plug 8 through the pull rope 9, thereby conducting the connection between the expansion water storage bag 6 and the water storage chamber 4;

[0063] Compared with the prior art, the present application realizes a closed connection between the sealing plug 8 and the external traction cable through the ingenious setting of the switching module, that is, on the premise of ensuring that the sealing plug 8 is opened smoothly, the sealing of each through hole on the fixed plate 2 is guaranteed to avoid water seepage during operation; and the operation of the entire device is simple and easy to use.

[0064] Furthermore, a sealing groove 16 is provided on the outer circumferential surface of each of the first sealing plate 11 and the second sealing plate 12. A sealing ring 17 is provided in the sealing groove 16. The sealing ring 17 can effectively improve the sealing performance between the first sealing plate 11 and the second sealing plate 12 and the fixed plate 2, thereby preventing the hot water in the water storage chamber 4 from leaking. At the same time, it can also ensure the pressure in the water storage chamber 4, thereby ensuring that the sliding frame 3 is pushed to slide.

[0065] Furthermore, a guide surface 18 with a conical structure is provided at the inlet end of the second stepped hole 15, and a thrust surface 19 adapted to the guide surface 18 is provided on the second sealing plate 12; when the second sealing plate 12 is fully inserted into the second stepped hole 15, the guide surface 18 and the thrust surface 19 are tightly fitted;

[0066] On the one hand, the setting of the guide surface 18 can enable the second sealing plate 12 to be quickly and accurately docked with the second step hole 15, thereby ensuring the rapid switching of the blocking state of the adjustment hole 10; on the other hand, it can be seen from the accompanying drawings that the second sealing plate 12 is located on the lower side of the fixed plate 2, that is, along the axial direction of the fixed plate 2, the second sealing plate 12 is inserted into the second step hole 15 from the bottom upward, and the guide surface 18 of the conical structure can fit more closely with the thrust surface 19 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 12 on the adjustment hole 10.

[0067] Finally, the guide surface 18 has a conical structure. The setting of the guide surface 18 effectively increases the contact area between the second sealing plate 12 and the second stepped hole 15, which is conducive to improving the sealing performance.

[0068] Furthermore, the gastric mucosal damage device also includes a water supply module, which includes a peristaltic pump 20 and a water supply pipe 21. The inlet end of the water supply pipe 21 is connected to the peristaltic pump 20, and the inlet end of the peristaltic pump 20 is connected to an external hot water tank; a plug-in pipe 22 is provided on the fixing plate 2, and the water supply pipe 21 is plugged and connected to the plug-in pipe 22;

[0069] At the same time, a filter is also provided at the output end of the plug pipe 22; the filter can prevent the sealing plug 8 from entering the water pipe 21 during the reverse pumping process, thereby ensuring the normal operation of the equipment;

[0070] When the gastric mucosal damage device described in the present application is used, it is inserted into the stomach through the patient's mouth, esophagus and cardia by means of a cannula. Then, hot water (with a temperature of 50°C-95°C) that meets the requirements is delivered to the water storage chamber via a peristaltic pump and a water pipe. As the hot water is continuously delivered, the hot water in the water storage chamber pushes the sliding frame to slide outward from the flexible guide tube under the action of its own water pressure until the limiting ring and the slider abut against each other.

[0071] Then, the medical staff adjusts the position of the flexible guide tube and selects the pulling cable to be pulled. When the pulling cable is pulled, the first sealing ring gradually disengages from the first step hole, and the second sealing plate gradually enters the second step hole, thereby replacing the first sealing plate to seal the adjustment hole. At the same time, when the pulling cable is pulled, the second sealing plate pulls the sealing plug through the pulling cable, thereby connecting the expansion water storage bag and the water storage chamber. The hot water in the water storage chamber enters the expansion water storage bag through the connecting pipe, causing it to expand rapidly.

[0072] After expansion, the expansion water wave will extend from the radial direction of the flexible guide tube through the expansion port and contact the gastric mucosa, thereby scalding the gastric mucosa;

[0073] When the scalding is over, the hot water in each expanded water storage bag and the water storage cavity can be quickly extracted by controlling the peristaltic pump to reverse. The expanded water storage bag will quickly shrink back into the sliding frame without the support of the hot water, and will also quickly retract under the action of the stomach pressure.

[0074] 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 through hot water, thereby achieving control of the size of the wound. Compared with the prior art 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 drastic temperature fluctuations and excessive burns to the gastric mucosa, but also the input hot water has reached a suitable burn 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 several expansion water storage bags according to their needs, which is beneficial to improving the efficiency of gastric burn surgery, avoiding the expansion of gastric mucosal wounds, and facilitating postoperative recovery; at the same time, compared with devices such as electric heating wires, the heating process of hot water is gentler, which can effectively control the degree of damage to the gastric mucosa, improve the fault tolerance of medical staff during surgery, and avoid excessive burns.

[0075] Secondly, compared with the method of temporary heating through a heating device, the present application can place the hot water heating device externally and set a water pipe in the flexible guide tube. It not only removes the heating device from the flexible guide tube, but also removes the temperature monitoring device, thereby maximally simplifying the internal structure of the flexible guide tube, which is conducive to improving the stability and reliability of the equipment.

[0076] Finally, when the present application is used, the water supply module can realize the automatic input and extraction of hot water, and the medical staff only needs to control the working status of the system by pulling the cable; at the same time, all the equipment are hidden in the flexible guide tube, and all the devices can be quickly and safely placed into the stomach through the intubation operation of the flexible guide tube, and the working status of the equipment can be controlled by pulling the cable, 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 beneficial to control the wound surface and improve the postoperative recovery effect.

[0077] 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.
