Abstract
Description
Technical Field
[0001] This invention relates to the field of fire needle knife technology, specifically to a fire needle knife for treating neck, shoulder, back and leg pain. Background Technology
[0002] In the clinical treatment of neck, shoulder, lower back and leg pain, fire needle knife therapy has become one of the commonly used treatment methods because it can improve local blood circulation and relieve muscle spasms through heat stimulation. Traditional fire needle therapy relies heavily on open flame heating, with the temperature entirely dependent on the doctor's experience, making precise quantitative control impossible. Excessive temperature can burn tissue, leading to infection or increased postoperative pain; insufficient temperature fails to achieve the desired therapeutic effect, failing to effectively relieve neck, shoulder, back, and leg pain symptoms. Especially in retained needle therapy scenarios, maintaining the fire needle temperature continuously is crucial. Existing devices lack real-time monitoring and dynamic adjustment mechanisms, resulting in large temperature fluctuations that further affect treatment stability. Therefore, it is necessary to propose a fire needle therapy device specifically for treating neck, shoulder, back, and leg pain. Summary of the Invention
[0003] To address the problems in the prior art, the present invention provides a fire needle knife for treating neck, shoulder, back and leg pain.
[0004] The technical solution adopted by this invention to solve its technical problem is as follows: a fire needle knife for treating neck, shoulder, waist and leg pain, comprising a housing, on which a fire needle knife is fixedly mounted; a storage groove is formed on the lower surface of the housing, and a fixing rod is slidably connected within the storage groove; a fixing hole is formed through the fixing rod, and a fixing groove is formed on the wall of the fixing hole; three sets of heating coils are fixedly mounted on the wall of the fixing groove; the lower end of the fire needle knife passes through the fixing hole and extends downward; a connecting plate is rotatably connected to the outer wall of the housing via a rotating shaft, and a [missing information - likely a component or component] is fixedly connected to the connecting plate. The mounting base has an internal mounting cavity, and a mounting hole is formed through the lower end wall of the mounting cavity. A T-shaped temperature sensor is slidably connected to the mounting cavity and the mounting hole. A spring is fixedly connected between the temperature sensor and the cavity wall. A lifting assembly is provided on the housing, and the lifting assembly is fixedly connected to a fixing rod. A pressing plate is fixedly connected to the lifting assembly. A sliding hole is formed through the connecting plate at the position corresponding to the pressing plate. The pressing plate extends outward through the sliding hole. An arc-shaped sliding hole is formed at the lower end of the sliding hole.
[0005] Specifically, the lifting assembly includes a lifting groove, which is formed on the outer side wall of the housing and is connected to the storage groove. A tension spring is fixedly connected to the top of the lifting groove, and a lifting plate is fixedly connected to the lower end of the tension spring. The lifting plate is fixedly connected to the pressing plate, and a connecting rod is fixedly connected to the lifting plate. The lower end of the connecting rod is fixedly connected to the fixing rod.
[0006] Specifically, a limiting rod is fixedly connected between the walls of the lifting groove, a limiting hole is opened through the lifting plate, the lifting plate is slidably connected to the limiting rod through the limiting hole, and the tension spring is sleeved on the wall of the limiting rod.
[0007] Specifically, the upper end of the fire needle knife extends through the outer shell, and the upper end of the fire needle knife abuts against the temperature sensor.
[0008] Specifically, the pressing plate is slidably connected to the sliding hole and the arc-shaped sliding hole, and the arc-shaped sliding hole is arranged in a surrounding shape about the rotating shaft.
[0009] Specifically, one set of the heating coils is positioned in the middle of the fire needle knife.
[0010] Specifically, the axis of the rotating shaft is parallel to the middle position of the fire needle knife.
[0011] The beneficial effects of this invention are as follows: The fire needle knife for treating neck, shoulder, back, and leg pain described in this invention, during use, lowers the heating coil to the head end of the fire needle knife and rotates the temperature sensor to the head end of the fire needle knife. The positions of the heating coil and temperature sensor are simultaneously fixed by the mutual limiting between the connecting plate and the pressing plate, achieving active heating and real-time monitoring of the fire needle knife head end. This eliminates the traditional open flame heating and experience-based temperature judgment mode, avoiding improper temperature control and improving the scientific nature of acupuncture and the stability of therapeutic efficacy. Furthermore, during needle retention, the middle section of the fire needle knife is heated by the middle coil. Utilizing the equidistant structure of the tail and head ends of the fire needle knife from the middle section, the temperature at the head end is indirectly and accurately controlled through tail end temperature monitoring. This perfectly adapts to the temperature requirements of different acupuncture stages in the treatment of neck, shoulder, back, and leg pain, avoiding the impact of temperature fluctuations on analgesia, anti-inflammation, and other therapeutic effects, significantly improving the treatment's specificity and safety, and thus enhancing the accuracy of temperature during fire needle knife acupuncture.

[0015] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0016] like Figures 1-6 As shown, the present invention provides the following technical solution: Example 1: A fire needle knife for treating neck, shoulder, waist and leg pain includes a housing 1, on which a fire needle knife 2 is fixedly mounted. A storage groove 3 is formed on the lower surface of the housing 1, and a fixing rod 4 is slidably connected within the storage groove 3. A fixing hole 5 is formed through the fixing rod 4, and a fixing groove 6 is formed on the wall of the fixing hole 5. Three sets of heating coils 7 are fixedly mounted on the wall of the fixing groove 6. The lower end of the fire needle knife 2 passes through the fixing hole 5 and extends downwards. A connecting plate 8 is rotatably connected to the outer wall of the housing 1 via a rotating shaft. A mounting base 9 is fixedly connected to the connecting plate 8, and the interior of the mounting base 9 has a... The mounting cavity 10 has a mounting hole 11 through the lower end cavity wall. The mounting cavity 10 and the mounting hole 11 are slidably connected to a T-shaped temperature sensor 12. The temperature sensor 12 and the cavity wall of the mounting cavity 10 are fixedly connected to a spring 13. The housing 1 is provided with a lifting assembly, which is fixedly connected to a fixing rod 4. A pressing plate 14 is fixedly connected to the lifting assembly. A sliding hole 15 is through the connecting plate 8 at the position corresponding to the pressing plate 14. The pressing plate 14 passes through the sliding hole 15 and extends outward. An arc-shaped sliding hole 16 is provided at the lower end of the sliding hole 15. When using it, the following steps are included: First step: Press the pressing plate 14 until it descends into the arc-shaped sliding hole 16. The pressing plate 14 will drive the lifting plate 19 to descend. The lifting plate 19 will drive the fixing rod 4 to descend through the connecting rod 20. The fixing rod 4 will slide on the fire needle knife 2 through the fixing hole 5 until it is sleeved on the lower end of the fire needle knife 2. The second step is to press the temperature sensor 12 upwards, causing it to move upwards and disengage from the upper end of the fire needle 2. Then, keep pressing the sensor and push the mounting base 9 to rotate. The mounting base 9 drives the connecting plate 8 to rotate synchronously about the shaft. At the same time, the pressing plate 14 moves within the arc-shaped sliding hole 16, which limits the pressing plate 14, preventing the lifting plate 19 from rising. This fixes the height of the fixing rod 4 and the heating coil 7. When the mounting base 9 rotates to the lower end of the fire needle 2, the temperature sensor 12 can be released. The spring 13 pushes the temperature sensor 12 upwards and abuts against the lower end of the fire needle 2. The third step is to activate the heating coil 7 and the temperature sensor 12. The heating coil 7 heats the puncture end of the fire needle knife 2, while the temperature sensor 12 monitors the temperature of the fire needle knife 2. When the required temperature is reached, the heating coil 7 can be stopped, thus eliminating the need for open flame heating and allowing doctors to judge the temperature of the fire needle knife 2 based on experience. Acupuncture can be performed more accurately based on the precise temperature of the fire needle knife 2. Fourth step: Then directly rotate the mounting base 9 and the connecting plate 8 to reset them. After the connecting plate 8 is reset, the sliding hole 15 will coincide with the pressing plate 14. At this time, the tension spring 18 will pull the lifting plate 19, and the lifting plate 19 will drive the pressing plate 14 to rise into the sliding hole 15. The pressing plate 14 supports the connecting plate 8 through the sliding hole 15 to prevent the connecting plate 8 from shifting outward during use. At the same time, the lifting plate 19 will pull the fixing rod 4 up through the connecting rod 20, so that the fixing rod 4 rises into the storage groove 3 and exposes the lower end of the fire needle knife 2. At this time, the fire needle knife 2 can be precisely heated to apply needles. Step 5: Partial Acupuncture Procedure After the fire needle 2 is inserted, it needs to remain in the body and be heated. At this time, a set of heating coils 7 and temperature sensors 12 located in the middle can be activated. After the heating coils 7 heat the middle section of the fire needle 2, the heat will be transferred through the fire needle 2. The distance between the tail end and the head end of the fire needle 2 and the middle section is the same. At this time, the temperature of the tail end of the fire needle 2 is monitored by the temperature sensor 12, so that the temperature of the head end of the fire needle 2 inserted into the body can be known. By controlling the heating power of the heating coils 7, the temperature of the head end of the fire needle 2 can be controlled, so that the temperature of the fire needle 2 can be accurately controlled for acupuncture.
[0017] Example 2: The technical solutions in this example that differ from Example 1 include: The lifting assembly includes a lifting groove 17, which is formed on the outer wall of the housing 1 and communicates with the storage groove 3. A tension spring 18 is fixedly connected to the top of the lifting groove 17, and a lifting plate 19 is fixedly connected to the lower end of the tension spring 18. The lifting plate 19 is fixedly connected to the pressing plate 14, and a connecting rod 20 is fixedly connected to the lifting plate 19. The lower end of the connecting rod 20 is fixedly connected to the fixing rod 4. A limiting rod 21 is fixedly connected between the groove walls of the lifting groove 17, and a limiting hole 22 is formed through the lifting plate 19. The lifting plate 19 is slidably connected to the limiting rod 21 through the limiting hole 22, and the tension spring 18 is sleeved on the rod wall of the limiting rod 21. Pressing the pressing plate 1... 4. The pressing plate 14 descends into the arc-shaped sliding hole 16, and the pressing plate 14 drives the lifting plate 19 to descend. The lifting plate 19 drives the fixing rod 4 to descend through the connecting rod 20. The fixing rod 4 slides on the fire needle knife 2 through the fixing hole 5 until it is fitted onto the lower end of the fire needle knife 2 to heat it. When the pressing plate 14 is released, the tension spring 18 pulls the lifting plate 19, and the lifting plate 19 drives the pressing plate 14 to rise into the sliding hole 15. The pressing plate 14 supports the connecting plate 8 through the sliding hole 15 to prevent the connecting plate 8 from shifting outward during use. At the same time, the lifting plate 19 pulls the fixing rod 4 upward through the connecting rod 20, so that the fixing rod 4 rises into the storage groove 3 and exposes the lower end of the fire needle knife 2.
[0018] The upper end of the fire needle knife 2 extends through the outer shell 1 and abuts against the temperature sensor 12. A set of heating coils 7 is located in the middle of the fire needle knife 2. After the heating coils 7 heat the middle section of the fire needle knife 2, the heat will be transferred through the fire needle knife 2. The distance between the tail end and the head end of the fire needle knife 2 and the middle section is the same. At this time, the temperature of the tail end of the fire needle knife 2 is monitored by the temperature sensor 12 to confirm the temperature of the head end of the fire needle knife 2, so as to facilitate the temperature control of the fire needle knife 2. The pressing plate 14 is slidably connected in the sliding hole 15 and the arc-shaped sliding hole 16. The arc-shaped sliding hole 16 is arranged in a circle about the rotating axis. The axis of the rotating axis is parallel to the middle position of the fire needle knife 2. The arc-shaped sliding hole 16 on the connecting plate 8 also rotates about the rotating axis, so that the pressing plate 14 will rotate in the arc-shaped sliding hole 16 when the connecting plate 8 rotates.
