Taking "robot coordinate system and / or m" as an example, it includes the robot coordinate system scheme, or the m scheme, or the scheme that the robot coordinate system and m satisfy at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is 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, wherein 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 connected in one piece, wherein the catheter body as a whole is a bendable hose, and the protective shell is arranged at the front end of the catheter body (one end directly inserted into the stomach), and the protective shell needs to be a medical hard tube, such as a hard PVC tube, etc.;

[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, avoid hot water leakage caused by pipe bending, and improve the reliability and stability of the entire device;

[0043] A fixing plate 2 is also provided in the protective shell of the flexible guide tube 1, and the fixing plate 2 is tightly connected to the protective shell; a sliding frame 3 is also slidably provided in the protective shell, and along the extension direction of the sliding frame 3, the sliding frame 3 is located at the front end of the fixing plate 2, and a water storage chamber 4 for temporarily storing hot water is provided between the fixing plate 2 and the sliding frame 3;

[0044] A limiting ring 5 is also provided at the outlet end of the protective shell. Along the axial direction of the protective shell, the limiting ring 5 limits 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 also provided at the front end of the protective shell, so as to prevent the edge of the protective shell from being too sharp, thereby 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 with 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 outside the flexible limiting ring 5;

[0047] A plurality of temporary storage chambers 303 are also provided on the limiting frame 302. The temporary storage chambers 303 are evenly arranged on the outer peripheral surface of the limiting frame 302 around the axis of the limiting frame 302. An expansion water storage bag 6 is provided in each temporary storage chamber 303. At the same time, a plurality of expansion ports 304 are also provided on the outer peripheral surface of the limiting frame 302. Each expansion port 304 is communicated with each temporary storage chamber 303 respectively.

[0048] A plurality of connecting tubes 305 are also provided on the slider 301. One end of each connecting tube 305 passes through the slider 301 and is connected to the water storage chamber 4. The other end of each connecting tube 305 is connected to the expansion water storage bag 6. Thus, the expansion water storage bag 6 is connected to the water storage chamber 4 through the connecting tube 305.

[0049] When working, the expansion water storage bag 6 in the expanded state can only extend from the expansion opening 304, thereby limiting the expansion direction of the expansion water storage bag 6, which is beneficial to controlling the location of the scald wound surface, and at the same time, it can also control the shape of the extended part of the expansion water storage bag 6, which is beneficial to controlling the size of the scald wound surface;

[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, and its volume can quickly expand by 5-10 times, or even more times, when filled with water.

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

[0052] The regulating assembly includes a sealing plug 8, a pull rope 9 and a switching module, wherein the sealing plug 8 is inserted into the inlet end of the connecting pipe 305, so as to cut off the connection channel between the expansion water storage bag 6 and the water storage chamber 4 through the sealing plug 8; the switching module includes a first sealing plate 11 and a second sealing plate 12, and 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 is an I-shaped structure as a whole;

[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 can realize the rapid installation and disassembly of the switching module;

[0054] A plurality of adjustment holes 10 are also provided on the fixing plate 2. Along the axial direction of the fixing plate 2, one end of each adjustment hole 10 is provided with a first step hole 14, and the other end thereof is provided with a second step hole 15, wherein the first step hole 14 is adapted to the first sealing plate 11, and the second step hole 15 is adapted to the second sealing ring, that is, the first step hole 14, the adjustment hole 10 and the second step hole 15 are coaxially connected in series according to 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 can be ensured that at the same time, only one of the first sealing plate 11 and the second sealing plate 12 can be plugged and connected to the adjusting hole 10, that is, since the length of the connecting rod 13 is greater than the length of the adjusting hole 10, after the first sealing plate 11 is fully inserted into the first step hole 14, the second sealing plate 12 and the second step hole 15 must be separated, and vice versa, the first sealing plate 11 and the first step hole 14 must be separated; on the other hand, by controlling the length of the connecting rod 13 to 1.5-2 times the length of the adjusting hole 10, the maximum distance between the first sealing plate 11 and the second sealing plate 12 and the fixing plate 2 can be controlled, so that during the control process, the second sealing plate 12 can be quickly and accurately docked with the second step hole 15 to avoid hot water leakage from the adjusting 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 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 directly opposite to the expansion port 304, so as to mark the expansion buckle and help 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 plurality of guide wheels or guide heads may be provided in the flexible guide tube 1, and each of the pulling cables 7 passes through the corresponding guide wheel or guide head and is led out of the flexible guide tube 1; this can separate the pulling cables 7 and prevent 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 to a certain extent, 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, but the stretched state of the drawstring 9 cannot affect the closed state of the sealing plug 8;

[0062] When in use, the sealing plug blocks the inlet end of the inflatable 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 breaks away 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 blocking 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 connecting the inflatable 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 smoothly opened, 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 the first sealing plate 11 and the second sealing plate 12, and 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 to prevent the hot water in the water storage chamber 4 from leaking, and at the same time can ensure the pressure in the water storage chamber 4 to ensure 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 step 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 step 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 adjusting 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 lower side upward, and the guiding 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 adjusting hole 10.

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

[0068] Furthermore, the gastric mucosal damage device further includes a water delivery module, which includes a peristaltic pump 20 and a water delivery pipe 21, the inlet end of the water delivery 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 delivery pipe 21 is plugged and connected to the plug-in pipe 22;

[0069] At the same time, a filter screen is also provided at the output end of the plug pipe 22; the filter screen 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 oral cavity, esophagus and cardia by means of a cannula, and then hot water (with a temperature of 50°C-95°C) that meets the requirements is delivered to the water storage chamber through a peristaltic pump and a water delivery pipe. As the hot water is continuously input, the hot water in the water storage chamber will push the sliding frame to slide out of the flexible guide tube under the action of its own water pressure until the limit 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 that needs to be pulled. When the pulling cable is pulled, the first sealing ring gradually breaks away 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, in the process of pulling the pulling cable, the second sealing plate will pull the sealing plug through the pulling rope, thereby connecting the expansion water storage bag and the water storage cavity. The hot water in the water storage cavity enters the expansion water storage bag through the connecting pipe, causing it to expand rapidly.

[0072] After expansion, the expansion water storage wave will extend out from the radial direction of the flexible guide tube through the expansion opening 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, and 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 surface. 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 and avoids excessive scalding of the gastric mucosa caused by drastic temperature fluctuations, but also the input hot water has reached a suitable scalding temperature, eliminating the heating waiting time and improving the efficiency of gastric mucosal scalding; 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 as needed, which is beneficial to improving the efficiency of gastric scalding 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 in performing surgery, and avoid excessive scalding.

[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 pipe. It not only removes the heating device from the flexible guide pipe, but also removes the temperature monitoring device, thereby simplifies the internal structure of the flexible guide pipe to the greatest extent, which is conducive to improving the stability and reliability of the equipment.

[0076] Finally, when the present application is used, the water delivery 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 is hidden in the flexible guide tube, and all the devices can be quickly and safely inserted 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 are not intended to 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.
