Description

Technical Field

[0001] The present invention relates to the technical field of digestive endoscopy, and in particular to a digestive endoscopy auxiliary device and an auxiliary method thereof. Background Art

[0002] Digestive endoscopy assistive devices are designed to improve the accuracy, safety and efficiency of endoscopic surgery and to meet the clinical demand for high-quality medical services. Due to irregular diet and gastric secretion disorders, food stays in the stomach for too long, or excessive consumption of foods containing large amounts of tannic acid and pectin, water-insoluble tannic acid proteins are easily formed under the action of gastric acid. Tannic acid proteins adhere to other foods and may eventually form gastric stones.

[0003] Laser lithotripsy is a highly efficient and minimally invasive technology. The strong shock waves generated by laser optical fiber can break stones into small pieces in a short time, so that the stones can be discharged with the digestive system, thereby achieving the purpose of removing stones. However, directly emitting lasers through optical fibers for lithotripsy cannot guarantee that the laser energy can act on the stones accurately and efficiently, nor can it guarantee to avoid damage to surrounding tissues. After laser lithotripsy, small pieces of stones may still adhere to the stomach wall, which may prevent patients from recovering quickly and may even cause subsequent problems such as inflammation and ulcers. Summary of the invention

[0004] The object of the present invention is to provide a digestive endoscopy auxiliary device and an auxiliary method thereof to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A digestive endoscope auxiliary device and an auxiliary method thereof, the auxiliary device comprising an operating end and an insertion end, the operating end and the insertion end being fixedly connected;

[0007] The insertion end includes a tube body, a laser lithotripsy mechanism, a protective mechanism, a residue removal mechanism, an ultrasonic sensor, a temperature sensor, a vibration sensor and a pressure sensor; the tube body is connected to the laser lithotripsy mechanism, the protective mechanism is fixedly connected to the tube body, the residue removal mechanism is fixedly connected to the tube body, the ultrasonic sensor is fixedly connected to the tube body, and the pressure sensor is fixedly connected to the tube body.

[0008] The insertion end enters from the biopsy hole of the digestive endoscope, and the gastric stones are crushed by the laser lithotripsy mechanism. During the lithotripsy process, the protective mechanism prevents the stones from splashing onto sensitive areas on the stomach wall or areas with dense blood vessels and nerve tissues, thereby providing protection for the patient during the laser lithotripsy process. The ultrasonic sensor can measure the distance between the stone and the laser lithotripsy mechanism, so that the focal length of the laser can be adjusted to ensure the efficiency of laser lithotripsy. The temperature sensor monitors the temperature in real time, and the high temperature state that may cause complications can be discovered and controlled in time to maintain a suitable operating temperature, ensuring the lithotripsy effect while protecting the surrounding tissues. The vibration sensor detects the vibration of the stone during the lithotripsy process, and the laser timing is controlled through data intelligence to avoid accidental injury to the surrounding tissues. By setting the pressure sensor at the front end of the endoscope or near the lithotripsy, the changes in the intragastric pressure during the lithotripsy operation can be monitored in real time and accurately, which is conducive to timely detection and control of the high pressure state in the stomach and prevention of serious complications such as gastric perforation. After the laser lithotripsy is completed, the small stones remaining in the stomach wall are cleaned up by the residual removal mechanism.

[0009] Furthermore, the laser lithotripsy mechanism includes an optical fiber, a focusing mirror, a magnetic block, a spring, a fixed block, a guide rail, a slider and a projection mirror. The tube body is provided with a No. 1 through hole, the optical fiber is located in the No. 1 through hole, the focusing mirror is slidably connected to the No. 1 through hole, the magnetic block is fixedly connected to the focusing mirror, two springs are provided, the spring is fixedly connected to the magnetic block, two fixed blocks are provided, the fixed block is fixedly connected to the spring, a mounting groove is provided in the No. 1 through hole, the guide rail is located in the mounting groove, the guide rail is slidably connected to the slider, the magnetic block is slidably connected to the guide rail, and the projection mirror is fixedly connected to the No. 1 through hole.

[0010] The distance between the end of the optical fiber and the stone is measured by an ultrasonic sensor, and the internal coil of the fixed block is energized to generate a magnetic field. The magnetic force generated by the magnetic field attracts the magnetic force of the magnetic block, and the magnetic block moves on the guide rail through the slider, thereby driving the focusing mirror to slide on the No. 1 through hole, so that the focusing point of the laser emitted from the end of the optical fiber on the stone surface can be adjusted to increase the energy density and improve the stone crushing efficiency. When the laser stone crushing is completed, the internal coil of the fixed block is powered off, so that the magnetic field generated by the fixed block disappears, thereby making the fixed block lose its magnetism. Under the action of the spring, the magnetic block returns to its initial position, waiting for the next focusing. The inside of the No. 1 through hole can be kept clean through the projection mirror.

[0011] Furthermore, the protection mechanism includes an airbag and an air pipe, the airbag is fixedly connected to the tube body, the air pipe is provided with a plurality of roots, the air pipe and the tube body are fixedly connected, the airbag is provided with an air inlet, and the air inlet is connected to the air pipe.

[0012] The balloon is deflated in its initial state, and its diameter is smaller than that of the outer tube, so that the insertion end can enter the biopsy hole of the digestive endoscope without affecting the insertion end. During the process of laser lithotripsy, the balloon is inflated through the air tube, so that the balloon becomes an annular loop arranged outside the tube body. During the laser lithotripsy process, the balloon prevents the broken stones from splashing out of the diameter of the balloon, thereby protecting the tissues around the stomach wall.

[0013] Furthermore, the residue removal mechanism includes a telescopic rod and a clamping portion, the tube body is provided with a second through hole, the telescopic rod is located in the second through hole, and the clamping portion and the telescopic rod are hingedly connected.

[0014] After laser lithotripsy is completed, for small pieces of gravel still remaining on the stomach wall, the clamping part is driven to the remaining gravel by the telescopic rod, and the cable is pulled to close the clamping part to clamp the small pieces of gravel. The telescopic rod contracts to clamp the small pieces of gravel out, thereby achieving the effect of removing the gravel.

[0015] Furthermore, the pipe body is provided with a water outlet No. 1, and the water outlet No. 1 is connected to the liquid delivery pipe.

[0016] During the laser lithotripsy process, a large amount of stone debris and blood will be produced after the stones are broken. These substances may block the surgical field of view and affect the doctor's observation and judgment. The liquid delivery tube can promptly deliver flushing fluid to the lithotripsy area to flush out the stone debris and blood, keeping the surgical field clear, which is helpful for doctors to more accurately identify the location, size and shape of the stones, thereby operating the laser lithotripsy more accurately and improving the success rate and safety of the operation.

[0017] Furthermore, the tube body is provided with a No. 3 through hole, the No. 3 through hole is provided with an objective lens, the No. 3 through hole is provided with a No. 2 water outlet, and the No. 2 water outlet is connected to the liquid delivery pipe.

[0018] The objective lens can be used to better monitor the laser lithotripsy process in real time and observe the reaction of surrounding tissues, so that the surgical strategy can be adjusted in time. At the same time, the position and size of the stones can be located more accurately, providing a more precise target for laser lithotripsy. The No. 2 water outlet can be used to clean the surface of the objective lens. The crushing of stones may produce debris or tiny particles, which may adhere to the surface of the objective lens. Therefore, the objective lens will not be affected by these substances and the field of vision will remain clear.

[0019] Furthermore, the operating end includes a handle, a gas delivery tube and a liquid delivery tube, wherein the gas delivery tube is fixedly connected to the upper end of the handle, and the liquid delivery tube is fixedly connected to the lower end of the handle.

[0020] By arranging the gas delivery tube and the liquid delivery tube at the upper and lower ends of the handle, the doctor can easily control the delivery of the flushing fluid without changing the holding posture, reducing hand fatigue. It can be operated with one hand or quickly adjusted with the assistance of the other hand, thereby improving the flexibility of operation.

[0021] A digestive endoscopy assisting method comprising the following steps:

[0022] S1: The distance between the end of the optical fiber and the stone is measured by an ultrasonic sensor, and the coil inside the fixed block is energized to generate a magnetic field. The magnetic force generated by the magnetic field drives the magnetic block to move on the guide rail through the slider, and then drives the focusing mirror to slide on the No. 1 through hole, so that the focusing point of the laser emitted by the end of the optical fiber on the stone surface can be adjusted;

[0023] S2: The end of the optical fiber emits laser to the surface of the stone, which converts the laser energy into heat energy, causing the surface temperature of the stone to rise rapidly. The thermal stress exceeds the tensile strength of the stone, causing the surface of the stone to break, thus completing the stone crushing.

[0024] S3: During the lithotripsy process, the airbag is rapidly inflated through the air tube, so that the airbag becomes an annular ring outside the tube to prevent debris from splashing around, thereby protecting the surrounding tissues.

[0025] S4: After the lithotripsy is completed, water is sprayed on the laser lithotripsy area through the No. 1 water outlet to flush away the debris and discharge it with the digestive system, thereby completing the cleaning of the lithotripsy area;

[0026] S5: Observe the lithotripsy area after cleaning through the objective lens, clamp the remaining small stones through the clamping part, and then retract the telescopic rod to clamp out the stones, so as to achieve the cleaning effect and improve the quality of lithotripsy;

[0027] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention measures the distance between the end of the optical fiber and the stone through an ultrasonic sensor, so that the coil inside the fixed block is energized to generate a magnetic field, and the magnetic force generated by the magnetic field attracts the magnetic force of the magnetic block, and the magnetic block moves on the guide rail through the slider, thereby driving the focusing mirror to slide on the No. 1 through hole, so that the focusing point of the laser emitted from the end of the optical fiber on the stone surface can be adjusted, the laser energy density can be increased, and it can be ensured that the laser energy can act on the stone accurately and efficiently, so that the lithotripsy efficiency is improved. The airbag is deflated in the initial state, and its diameter is smaller than the diameter of the outer tube, so that it does not affect the insertion end from entering the biopsy hole of the digestive endoscope. In the process of lithotripsy by the laser lithotripsy mechanism, The balloon is inflated through the air tube, so that the balloon becomes an annular loop arranged outside the tube body. During the laser lithotripsy process, the stones are broken, and the airbag is used to prevent the stones from splashing out of the diameter of the balloon, thereby protecting the tissues around the stomach wall. After the laser lithotripsy is completed, for small pieces of stones that may still remain on the stomach wall, the clamping part is driven to the remaining stones by the telescopic rod, and the cable is pulled to close the clamping part to clamp the small pieces of stones. The telescopic rod contracts to clamp the small pieces of stones out, thereby achieving the effect of clearing the stones and avoiding multiple operations, thereby significantly shortening the operation time, improving the operation efficiency, helping patients recover their health faster, and reducing the length of hospital stay and the risk of complications during the recovery period.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] The present invention provides a technical solution:

[0036] like Figure 1-2 As shown, a digestive endoscope auxiliary device and an auxiliary method thereof, the auxiliary device comprises an operating end 1 and an insertion end 2, the operating end 1 and the insertion end 2 are fixedly connected;

[0037] The insertion end 2 includes a tube body 21, a laser lithotripsy mechanism 22, a protection mechanism 23, a residue removal mechanism 24, an ultrasonic sensor 25, a temperature sensor 26, a vibration sensor 27 and a pressure sensor 28. The tube body 21 is connected to the laser lithotripsy mechanism 22, the protection mechanism 23 is fixedly connected to the tube body 21, the residue removal mechanism 24 is fixedly connected to the tube body 21, the ultrasonic sensor 25 is fixedly connected to the tube body 21, and the pressure sensor 28 is fixedly connected to the tube body 21.

[0038] The insertion end 2 is inserted into the biopsy hole of the digestive endoscope, and the gastric stones are crushed by the laser lithotripsy mechanism 22. During the lithotripsy process, the protection mechanism 23 prevents the stones from splashing onto sensitive areas on the stomach wall or areas where blood vessels and nerve tissues are densely distributed, thereby providing protection for the patient during the laser lithotripsy process. The ultrasonic sensor 25 can measure the distance between the stone and the laser lithotripsy mechanism 22, so that the focal length of the laser can be adjusted to ensure the efficiency of the laser lithotripsy. The temperature can be monitored in real time by the temperature sensor 26, so that the high temperature state that may cause complications can be discovered and controlled in time to maintain a suitable operating temperature, ensure the lithotripsy effect and protect the surrounding tissues. The vibration sensor 27 detects the vibration of the stone during the lithotripsy process, and the laser timing is controlled by data intelligence to avoid accidental injury to the surrounding tissues. By arranging the pressure sensor 28 at the front end of the endoscope or near the lithotripsy, the changes in the intragastric pressure during the lithotripsy operation can be monitored in real time and accurately, which is conducive to timely discovering and controlling the high pressure state in the stomach and preventing the occurrence of serious complications such as gastric perforation. After the laser lithotripsy is completed, the small stones remaining in the stomach wall are cleaned up by the residual cleaning mechanism 24.

[0039] like Figure 3-4 As shown, the laser lithotripsy mechanism 22 includes an optical fiber 221, a focusing mirror 222, a magnetic block 223, a spring 224, a fixed block 225, a guide rail 226, a slider 227 and a projection mirror 228. The tube body 21 is provided with a No. 1 through hole 211, the optical fiber 221 is located in the No. 1 through hole 211, the focusing mirror 222 is slidably connected to the No. 1 through hole 211, the magnetic block 223 is fixedly connected to the focusing mirror 222, two springs 224 are provided, the spring 224 is fixedly connected to the magnetic block 223, two fixed blocks 225 are provided, the fixed block 225 is fixedly connected to the spring 224, a mounting groove is provided in the No. 1 through hole 211, the guide rail 226 is located in the mounting groove, the guide rail 226 is slidably connected to the slider 227, the magnetic block 223 is slidably connected to the guide rail 226, and the projection mirror 228 is fixedly connected to the No. 1 through hole 211.

[0040] The distance between the end of the optical fiber 221 and the stone is measured by the ultrasonic sensor 25, so that the internal coil of the fixed block 225 is energized to generate a magnetic field. The magnetic force generated by the magnetic field is attracted by the magnetic force of the magnetic block 223. The magnetic block 223 moves on the guide rail 226 through the slider 227, thereby driving the focusing mirror 222 to slide on the first through hole 211, so that the focusing point of the laser emitted from the end of the optical fiber 221 on the stone surface can be adjusted to increase the energy density and improve the stone crushing efficiency. When the laser stone crushing is completed, the internal coil of the fixed block 225 is powered off, so that the magnetic field generated by the fixed block 225 disappears, thereby making the fixed block 225 lose its magnetism. Under the action of the spring 224, the magnetic block 223 returns to its initial position to wait for the next focusing. The inside of the first through hole 211 can be kept clean through the projection mirror 228.

[0041] like Figure 3 As shown, the protection mechanism 23 includes an airbag 231 and an air pipe 232. The airbag 231 is fixedly connected to the tube body 21. The air pipe 232 is provided with a plurality of air pipes. The air pipe 232 is fixedly connected to the tube body 21. The airbag 231 is provided with an air inlet, and the air inlet is connected to the air pipe 232.

[0042] The airbag 231 is deflated in its initial state, and its diameter is smaller than that of the outer tube, so that it does not affect the insertion end 2 from entering the biopsy hole of the digestive endoscope. During the process of lithotripsy by the laser lithotripsy mechanism 22, the airbag 231 is inflated through the air supply tube 232, so that the airbag 231 becomes an annular trap arranged outside the tube body 21. During the laser lithotripsy process, the stones are crushed, and the airbag 231 is used to prevent the stones from splashing out of the diameter of the airbag 231, thereby achieving a protective effect on the surrounding tissues of the stomach wall.

[0043] like Figure 2-3 As shown, the residue removal mechanism 24 includes a telescopic rod 241 and a clamping portion 242. The tube body 21 is provided with a second through hole, the telescopic rod 241 is located in the second through hole, and the clamping portion 242 and the telescopic rod 241 are hingedly connected.

[0044] After laser lithotripsy is completed, for small pieces of gravel still remaining on the stomach wall, the clamping part 242 is driven to the remaining gravel by the telescopic rod 241, and the cable is pulled to close the clamping part 242 to clamp the small pieces of gravel, and the telescopic rod 241 contracts to clamp the small pieces of gravel, thereby achieving the effect of removing the gravel.

[0045] like Figure 2 As shown, the pipe body 21 is provided with a first water outlet 212 , and the first water outlet 212 is connected to the liquid delivery pipe 13 .

[0046] During the laser lithotripsy process, a large amount of stone chips and blood will be produced after the stones are broken. These substances may block the surgical field of view and affect the doctor's observation and judgment. The liquid delivery tube 13 can promptly deliver flushing liquid to the lithotripsy area to flush out the stone chips and blood, keep the surgical field clear, and help the doctor more accurately identify the location, size and shape of the stones, thereby operating the laser lithotripsy more accurately and improving the success rate and safety of the operation.

[0047] like Figure 3 As shown, the tube body 21 is provided with a third through hole, the third through hole is provided with an objective lens 213 , the third through hole is provided with a second water outlet 214 , and the second water outlet 214 is connected to the liquid delivery pipe 13 .

[0048] The objective lens 213 can be used to better monitor the laser lithotripsy process in real time and observe the reaction of surrounding tissues, so that the surgical strategy can be adjusted in time. At the same time, the position and size of the stone can be located more accurately, providing a more precise target for laser lithotripsy. The second water outlet 214 can be used to clean the surface of the objective lens 213. The crushing of the stone may produce debris or tiny particles, which may adhere to the surface of the objective lens 213. Therefore, the surface of the objective lens 213 will not be affected by these substances, so as to maintain a clear field of vision.

[0049] like Figure 1 As shown, the operating end 1 includes a handle 11, a gas delivery pipe 12 and a liquid delivery pipe 13, wherein the gas delivery pipe 12 is fixedly connected to the upper end of the handle 11, and the liquid delivery pipe 13 is fixedly connected to the lower end of the handle 11.

[0050] By arranging the gas delivery tube 12 and the liquid delivery tube 13 at the upper and lower ends of the handle 11, the doctor can easily control the delivery of the flushing liquid without changing the holding posture, reducing hand fatigue, and can operate with one hand or quickly adjust with the assistance of the other hand, thereby improving the flexibility of operation.

[0051] A digestive endoscopy assisting method comprising the following steps:

[0052] S1: The distance between the end of the optical fiber 221 and the stone is measured by the ultrasonic sensor 25, and the internal coil of the fixed block 225 is energized to generate a magnetic field. The magnetic force generated by the magnetic field drives the magnetic block 223 to move on the guide rail 226 through the slider 227, and then drives the focusing mirror 222 to slide on the first through hole 211, so as to adjust the focusing point of the laser emitted by the end of the optical fiber 221 on the stone surface;

[0053] S2: The end of the optical fiber 221 emits laser to the stone surface, and by converting the laser energy into heat energy, the temperature of the stone surface rises rapidly. The thermal stress exceeds the tensile strength of the stone, causing the stone surface to break, thereby completing the stone crushing;

[0054] S3: During the lithotripsy process, the airbag 231 is rapidly inflated through the air delivery tube 232, so that the airbag 231 becomes an annular ring disposed outside the tube body 21 to prevent debris from splashing around, thereby protecting the surrounding tissues;

[0055] S4: After the lithotripsy operation is completed, water is sprayed on the laser lithotripsy area through the first water outlet 212 to wash away the debris and discharge it with the digestive system, thereby completing the cleaning of the lithotripsy area;

[0056] S5: Observe the lithotripsy area after cleaning through the objective lens 213, clamp the remaining small stones through the clamping part 242, and then retract the telescopic rod 241 to clamp the stones out, so as to achieve the cleaning effect and improve the quality of lithotripsy surgery;

[0057] Working principle of the present invention:

[0058] The insertion end 2 enters through the biopsy hole of the digestive endoscope. After reaching the working position, the ultrasonic sensor 25 measures the distance between the end of the optical fiber 221 and the stone, so that the internal coil of the fixing block 225 is energized to generate a magnetic field. The magnetic force generated by the magnetic field is attracted by the magnetic force of the magnetic block 223. The magnetic block 223 moves on the guide rail 226 through the slider 227, thereby driving the focusing lens 222 to slide on the first through hole 211, so that the laser emitted from the end of the optical fiber 221 can be adjusted to focus on the stone surface. After the focus adjustment is completed, the laser is emitted through the optical fiber 221 to crush the gastric stone. During the lithotripsy process, the protective mechanism 23 inflates the airbag 231 through the air pipe 232, so that the airbag 231 becomes an annular trap arranged outside the tube body 21. During the laser lithotripsy process, the stone is crushed, and the airbag 231 prevents the crushed stone from splashing out of the diameter range of the airbag 231, thereby achieving the protection of the surrounding tissues of the stomach wall. The temperature is monitored in real time by the temperature sensor 26 to maintain the appropriate temperature. The appropriate operating temperature ensures the lithotripsy effect while protecting the surrounding tissues. The vibration sensor 27 detects the vibration of the stone during the lithotripsy process. By comparing the vibration intensity, the time when the stone is broken is obtained, and the laser timing is intelligently controlled to avoid accidental injury to the surrounding tissues. By arranging the pressure sensor 28 at the front end of the endoscope or near the lithotripter, the changes in the intragastric pressure during the lithotripsy operation can be monitored in real time and accurately to prevent the occurrence of serious complications such as gastric perforation. After the laser lithotripsy is completed, the internal coil of the fixed block 225 is powered off, so that the magnetic field generated by the fixed block 225 disappears, thereby making the fixed block 225 lose its magnetism. Under the action of the spring 224, the magnetic block 223 returns to its initial position to wait for the next focusing. After the laser lithotripsy is completed, for the remaining small stones, the clamping part 242 is driven to the remaining gravel by the telescopic rod 241, and the cable is pulled to close the clamping part 242 to clamp the small gravel, and the telescopic rod 241 contracts to clamp the small gravel.
