[0002] Acupuncture is a common method in Traditional Chinese Medicine (TCM) used to alleviate spinal-related problems. As a traditional TCM therapy, acupuncture involves inserting fine needles into specific acupoints to stimulate nerves and muscles, thereby improving bodily function. In the treatment of conditions such as spinal cord injuries, acupuncture is believed to unblock meridians, promote blood circulation, and relieve muscle tension and pain.

[0003] Acupuncture involves inserting specially designed needles into selected acupoints to harmonize Yin and Yang and promote the flow of Qi and blood. Traditional Chinese medicine acupuncture is performed by a professional TCM practitioner who develops a personalized treatment plan based on the patient's condition, selecting acupoints and then administering the acupuncture treatment.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figures 1 to 4 This invention discloses an acupuncture device suitable for the rehabilitation of urinary and fecal disorders caused by spinal cord injury, comprising: The housing 1 has a needle storage cavity inside for placing multiple metal needle modules 19. The needle storage cavity is provided with a push module and a transfer module, which are located on both sides of the needle storage cavity. And an injection chamber connected to the needle storage chamber, one end of the transfer module is connected to the needle storage chamber, and the other end of the transfer module is connected to the injection chamber. The transfer module is used to transfer one of the metal needle modules 19 into the injection chamber. The metal needle module 19 enters the injection chamber and connects to the air outlet of the air injection module. The metal needle module 19 includes a vertically sliding rubber block 1904 and a needle 1905 fixed coaxially with the rubber block 1904. After the metal needle module 19 connects to the air outlet of the air injection module, the air injection module inflates and pushes the rubber block 1904 to slide, thereby driving the needle 1905 to pierce the acupoint.

[0021] In use, the device involves placing multiple metal needle modules 19 within the needle storage chamber of the housing 1. During treatment, a push-up module and a transport module work together within the needle storage chamber; one end of the transport module connects to the needle storage chamber, and the other end connects to the injection chamber, its function being to transfer a single metal needle module 19 from the needle storage chamber to the injection chamber. Once the metal needle module 19 is in place in the injection chamber, it connects to the outlet end of the gas injection module. Subsequently, the gas injection module begins inflation, and the resulting gas pressure acts on a vertically sliding rubber block 1904 inside the metal needle module 19, pushing the rubber block 1904 to slide. Since the needle 1905 is coaxially fixed with the rubber block 1904, this sliding directly drives the needle 1905 to pierce the patient's target acupoint. The insertion depth can be adjusted by adjusting the gas output of the gas injection module. This device achieves multi-site, continuous, and force-controllable acupuncture operations through mechanical automation, aiming to improve the efficiency and standardization of rehabilitation treatment for complications such as urinary and fecal incontinence following spinal cord injury.

[0022] As an optional implementation, the push module includes a sliding block 2, which is slidably fitted in the needle storage cavity. One end of the sliding block 2 is fixed with one end of a spring 3, and the other end of the spring 3 is fixed to the inner wall of the needle storage cavity.

[0023] When the needle storage chamber is full of metal needle modules 19, the spring 3 is compressed. The restoring force of the spring 3 provides power to the sliding block 2, enabling it to stably push the designated metal needle module 19 into the transfer module, preparing it for subsequent needle-punching operations. This structure utilizes the spring 3 to achieve simple and reliable automatic feeding of the transfer module.

[0024] As an optional implementation, the top of the needle reservoir is open, and the top of the needle reservoir is used to insert the metal needle module 19. The top of the needle reservoir is detachably connected to a cover 9, and a needle tip positioning point 10 is fixed on the cover 9. The needle tip positioning point 10 is coaxially arranged with the needle 1905 located in the injection chamber.

[0025] Before use, the operator inserts multiple metal needle modules 19 through the opening at the top of the needle storage chamber and then seals it with the cover 9. The needle tip positioning point 10 fixed on the cover 9 is coaxial with the needle 1905 that will eventually enter the injection chamber. During use, simply aligning the needle tip positioning point 10 with the patient's acupoint ensures that the needle 1905, which is then inserted from the injection chamber, can accurately act on the target acupoint, achieving a combination of rapid needle loading and precise positioning.

[0026] A wedge-shaped ramp is provided on the top of the sliding block 2 to assist in the insertion of the metal needle module 19. When the metal needle module 19 is installed, the inserted metal needle module 19 pushes the sliding block 2 to one side through the action of the wedge-shaped ramp, compressing the spring 3, thereby completing the installation. As an optional implementation, the transfer module includes a slide 13 formed on the side wall of the needle storage cavity, a threaded rod 14 rotatably fitted inside the slide 13, one end of the threaded rod 14 being coaxially fixed to the output shaft of the motor 11, and the fixed end of the motor 11 being fixed inside the housing 1. The threaded rod 14 is threadedly fitted with a threaded sliding module 17; After the threaded sliding module 17 is engaged with one of the metal needle modules 19, the threaded rod 14 rotates to make the threaded sliding module 17 slide along the slide rail 13 to push the metal needle module 19 engaged with it into the injection cavity.

[0027] When the metal needle module 19 needs to be transferred, the motor 11 starts, driving the threaded rod 14, which is coaxially fixed to its output shaft, to rotate within the slide rail 13. The threaded sliding module 17, which is threadedly engaged with the threaded rod 14, then slides along the slide rail 13. This threaded sliding module 17 forms a limiting engagement with a specific metal needle module 19, and during its sliding process, it precisely pushes the metal needle module 19 into the injection chamber, preparing for subsequent needle puncture operations.

[0028] As an optional implementation, the threaded sliding module 17 includes a threaded block 1701, which is slidably disposed in the slide rail 13, and a threaded hole 1705 is formed in the middle of the threaded block 1701 for threaded engagement with the threaded rod 14. A limit block 1702 is fixed in threaded hole 1705, a limit protrusion 1704 is fixed at the bottom of limit block 1702, and an air passage 1703 is opened in limit block 1702. The top of the needle storage cavity is provided with a relief groove 12 to accommodate the limiting block 1702; After the limiting block 1702 enters the relief groove 12, the plane where the limiting protrusion 1704 is located serves as the first limiting plane. One of the metal needle modules 19 is pushed in and contacts one side of the limiting protrusion 1704 and the bottom of the limiting block 1702, and is limited and matched with the first limiting plane, and one end of the air passage 1703 is connected to the metal needle module 19. At this time, the metal needle module 19, which is in contact with one side of the limiting protrusion 1704 and the bottom of the limiting block 1702, together with the side wall of the limiting block 1702, forms the second limiting plane, and the second limiting plane cooperates with the next metal needle module 19 in a limiting manner. When the limit block 1702 moves down, it pushes the corresponding metal needle module 19 into the injection cavity and connects the other end of the air passage 1703 to the air injection module. The top of the limiting block 1702 is higher than the bottom wall of the needle storage cavity, so that the next metal needle module 19 is always in a limiting engagement with the second limiting plane; After the needle 1905 of the metal needle module 19 located in the injection chamber is inserted... After the limiting block 1702 moves to the clearance groove 12 opened at the top of the needle storage cavity, the next metal needle module 19 is pushed into the first limiting plane.

[0029] When the motor 11 drives the threaded rod 14 to rotate, the threaded block 1701, which is threadedly engaged with it, slides along the slide rail 13. The limiting block 1702, which is fixed to the threaded block 1701, moves accordingly. The first limiting plane formed by the limiting protrusion 1704 at its bottom is used to position a metal needle module 19. After the limiting block 1702 enters the clearance groove 12 at the top of the needle storage cavity, it can move downward. At this time, its side wall will push the positioned metal needle module 19 into the injection cavity. At the same time, one end of the air passage 1703 inside the limiting block 1702 is connected to the metal needle module 19, and the other end is connected to the air injection module, preparing for needle puncture. After the metal needle module 19 engages with the first limiting plane, it and the bottom of the limiting block 1702 together form a second limiting plane, which can effectively block subsequent metal needle modules 19 and ensure that the needle modules in the needle storage cavity are arranged in an orderly manner. Because the top of the limiting block 1702 is higher than the bottom wall of the needle storage cavity, the second limiting plane is always present when it performs the pushing action, preventing the next metal needle module 19 from accidentally slipping off. When the needle 1905 in the injection cavity completes insertion, the limiting block 1702 moves upward and retracts into the clearance groove 12, the second limiting plane disappears, and the subsequent metal needle module 19 is pushed to the position of the first limiting plane by the pushing module in the needle storage cavity, waiting for the next transfer. The entire process achieves automatic, precise, and cyclic delivery of the metal needle module 19 through ingenious mechanical limiting and air circuit docking.

[0030] As an optional implementation, the metal needle module 19 includes a magnetic rod 1901, a rubber block 1904 that slides vertically coaxially within the magnetic rod 1901, a limiting guide ring 1906 that is coaxially fixed at the bottom of the magnetic rod 1901, the limiting guide ring 1906 that is limited to the bottom of the rubber block 1904, and the limiting guide ring 1906 that slides vertically with the needle 1905. The top of the magnetic rod 1901 is coaxially threaded with a nut 1902, and the center of the nut 1902 has an air hole 1903 that communicates with the air passage 1703; The magnetic rod 1901 is magnetically engaged with one side wall of the injection cavity.

[0031] The metal needle module 19 is connected to the air passage 1703 via a nut 1902 and an air hole 1903 at its top to introduce gas. The gas pressure pushes the rubber block 1904 inside the magnetic rod 1901 to slide vertically along the limiting guide ring 1906, thereby precisely driving the needle 1905 to pierce out. At the same time, the magnetic rod 1901 utilizes its magnetism to form a stable magnetic engagement with one side wall of the injection chamber, ensuring accurate positioning of the module in the working position.

[0032] As an optional implementation, an electromagnetic adsorption plate 20 is fixed on one side of the injection cavity. The electromagnetic adsorption plate 20 is magnetically attracted to the magnetic rod 1901. The electromagnetic adsorption plate 20 is electrically connected to a controller and a battery 7. The controller and battery 7 are fixed inside the housing 1. The controller and battery 7 are electrically connected to a button 16, which is fixed to the top of the side wall of the housing 1. A needle outlet 18 is provided on the other side of the injection chamber; The gas injection module is electrically connected to the controller and battery 7.

[0033] When the metal needle module 19 is inserted into the injection chamber, its magnetic rod 1901 firmly adheres to the electromagnetic adsorption plate 20 fixed to one side of the injection chamber, achieving precise positioning. When the operator presses button 16, the controller and battery 7 activate the gas injection module, while simultaneously ensuring the electromagnetic adsorption plate 20 remains engaged. Gas pushes the internal structure of the needle module, causing the needle 1905 to be precisely inserted, completing the treatment. Once the gas injection module reaches the preset injection volume, it stops injecting gas, and the electromagnetic adsorption plate 20 is de-energized. At this point, the metal needle module 19 is fixed to the patient, and the metal needle module 19 is moved out of the needle outlet 18 by moving the housing 1.

[0034] Throughout the process, electromagnetic adsorption provides stable fixation, while the electronic control system enables integrated and automated operation.

[0035] As an optional implementation, the air injection module includes a peristaltic pump 5, which is fixed inside the housing 1, and the air inlet of the peristaltic pump 5 is connected to the atmosphere through the air inlet duct 4. The outlet end of the peristaltic pump 5 is connected to one end of the air passage 1703 through the air outlet passage 6; The outlet end of the air outlet 6 is connected to a solenoid valve and a gas flow meter.

[0036] When acupuncture is required, the peristaltic pump 5 starts, drawing in air from its inlet 4 and then outputting the gas through the outlet 6. The gas flows through the outlet 6, where a solenoid valve controls the opening and closing of the air path and a gas flow meter monitors the gas flow rate. Finally, the gas enters the metal needle module 19 through the air passage 1703, pushing the rubber block 1904 and the needle 1905 to complete a precise and controllable insertion action.

[0037] As an optional implementation, an infrared heat therapy module 8 is also included, which is fixed to the bottom of the housing 1 and electrically connected to the controller and the battery 7.

[0038] The infrared heat therapy module 8 is fixed to the bottom of the housing 1 and is electrically connected to the controller and battery 7. During acupuncture treatment, the controller can activate the infrared heat therapy module 8 to emit infrared light to perform heat therapy on the acupoints, realizing the synergistic effect of acupuncture and infrared heat therapy.

[0039] As an optional implementation, a handle 15 is fixed to one side of the housing 1, and a button 16 is disposed inside the handle 15.

[0040] The handle 15 fixed on one side of the housing 1 is easy to hold, and the button 16 inside it allows the operator to hold the device stably with one hand and easily start the treatment program.
