Description

Technical Field

[0001] The invention relates to the technical field of bone and joint diseases, in particular to an auxiliary device for promoting the repair of articular cartilage. Background Art

[0002] Articular cartilage is a smooth, elastic tissue covering the surface of joints. Its main function is to reduce friction between joint surfaces and cushion the impact on joints, thereby protecting joints and enabling smooth movement. However, due to aging, sports injuries, diseases or genetic factors, articular cartilage may wear, degenerate or be damaged, leading to problems such as joint pain, stiffness, swelling and dysfunction.

[0003] Articular cartilage damage can seriously affect the patient's quality of life, such as causing mobility problems and restrictions on daily life. Articular cartilage repair and the use of assistive devices can help patients improve these symptoms and improve their quality of life.

[0004] Currently available articular cartilage repair auxiliary devices are often bound to the patient's legs, have the functions of cold compress and hot compress, and use motors to provide auxiliary force to the patient when the patient flexes, thereby reducing the pressure on the patient's articular cartilage. However, when the motor is used to provide auxiliary force to the patient, the auxiliary force provided by the motor to the patient cannot be dynamically adjusted, and the patient's knee joint is relatively stiff in the process of restoring to a horizontal position. Therefore, it is necessary to propose an articular cartilage repair promoting auxiliary device that can be dynamically adjusted. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide an auxiliary device for promoting articular cartilage repair, which can realize dynamic adjustment according to the patient's specific situation and needs through electromagnets, iron sheets and controllers, provide personalized treatment intensity, and reduce unnecessary pressure and discomfort.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: an auxiliary device for promoting articular cartilage repair, comprising a leg cuff, both ends of the surface of the leg cuff are provided with binding components for binding the leg cuff to the patient's legs, the inner sleeve of the leg cuff is provided with a binding component for restraining the patient's legs, a cavity is opened between the leg cuff and the binding component, a cold compress component for providing a cold compress effect to the patient, a hot compress component for providing a hot compress effect to the patient and a power supply component are provided in the cavity; a controller and a bending judgment component for judging the degree of bending of the leg cuff are also provided in the cavity.

[0007] An electromagnet and a gear are provided in the cavity, one side of the electromagnet is fixedly connected to a support rod, the end of the support rod away from the electromagnet passes through the gear and is slidably connected to the inner wall of the cavity, and the support rod is rotatably connected to the gear; a driving member is slidably connected to the inner wall of the cavity, the output shaft of the driving member is fixedly connected to the gear, a rack is meshed at the bottom of the gear, and the rack is fixedly connected to the bottom wall of the cavity.

[0008] An iron sheet for restoring the horizontal position of the leg cover is also arranged in the cavity, one end of the iron sheet is fixedly connected to the inner wall of the cavity, and the other end of the iron sheet is located on the same horizontal plane as the electromagnet.

[0009] The controller is used to control the driving gear to rotate and increase the magnetic force of the electromagnet when the bending judgment component determines that the leg cover is bent. When the bending judgment component determines that the leg cover is not bent, the controller controls the magnetic force of the electromagnet to weaken.

[0010] The principle of the basic scheme is: the bending judgment component will continuously detect the bending angle of the leg cuff. When the patient's leg bends, the bending component will detect this change and transmit the bending angle signal data of the leg cuff to the controller. After receiving the signal, the controller controls the driving part to start, and the driving part drives the gear to rotate. Since the gear is rotatably connected to the support rod, and the other end of the support rod is fixedly connected to the electromagnet, the rotation of the gear will drive the electromagnet to move in the cavity.

[0011] The controller increases the magnetic force of the electromagnet to attract the iron sheet, thereby generating a traction force on the iron sheet to the leg sleeve, helping the patient to support the leg, thereby reducing unnecessary pressure and discomfort on the patient's legs. When the bending judgment component detects that the leg sleeve has returned to the horizontal position, the controller controls the magnetic force of the electromagnet to weaken, and the attraction between the electromagnet and the iron sheet is reduced accordingly.

[0012] The beneficial effects of the basic program are:

[0013] 1. The present invention adjusts the bending angle of the leg cuff by means of an electromagnet and an iron sheet, which is conducive to realizing dynamic adjustment of the bending angle of the leg cuff and providing a continuous and stable supporting force for the patient.

[0014] 2. The present invention realizes dynamic adjustment of the leg cuff by means of magnetic attraction between the electromagnet and the iron sheet, which is beneficial to reduce direct pressure on the patient's legs and improve the patient's comfort.

[0015] 3. The device helps accelerate the patient's recovery process by providing dynamically adjusted treatment intensity and continuous treatment effects. This accelerated recovery helps shorten the patient's recovery period, reduce the medical burden, and also helps the patient better restore his daily life and work ability.

[0016] Furthermore, the cavity also includes a buffer component for providing buffering for the iron sheet, and the buffer component includes a spring, one end of the spring is fixedly connected to the inner wall of the cavity away from one end of the iron sheet, and the other end of the spring is fixedly connected to the iron sheet.

[0017] The beneficial effect of the basic solution is that the spring provides a certain buffering force when the iron sheet is subjected to the magnetic force of the electromagnet. This buffering force helps to reduce the violent movement of the iron sheet due to sudden attraction by the strong magnetic force, thereby reducing the patient's discomfort and enhancing the stability of the equipment.

[0018] Furthermore, the binding assembly includes a plurality of binding straps, and the binding straps are all fixedly connected to the leg coverings.

[0019] The beneficial effect of the basic solution is that the leg cuffs are bound to the patient's legs by the binding belt, which is conducive to improving the stability of the leg cuffs on the patient's legs and reducing the falling off or displacement of the leg cuffs during use.

[0020] Furthermore, the binding assembly includes an elastic binding belt, a plurality of first small holes are opened on the surface of the elastic binding belt, and second small holes are opened at positions on the surface of the leg cover corresponding to the first small holes.

[0021] The beneficial effect of the basic solution is that the first small hole and the second small hole form multiple ventilation channels between the elastic binding belt and the leg cover, thereby enhancing the overall breathability. This helps to reduce the stuffiness and discomfort caused by long-term wearing and improve the comfort of the patient.

[0022] Furthermore, the power supply assembly includes a power supply, the power supply is fixedly connected to the top wall of the cavity, the controller is signal-connected to the power supply, and the power supply is electrically connected to the iron sheet.

[0023] The beneficial effects of the basic scheme are: as the energy source of the equipment, the stable connection and power supply of the power supply are the basis for ensuring the normal operation of the equipment. By fixing the power supply to the top wall in the cavity, it is beneficial to the stability and reliability of the power supply during the use of the equipment, and reduces equipment failures caused by power supply shedding or poor connection. By electrically connecting the power supply to the iron sheet, the current can be released to the patient through the iron sheet, and the current is conducive to stimulating the regeneration and proliferation of chondrocytes. This stimulation helps to accelerate the repair process of cartilage damage and promote the recovery of cartilage tissue.

[0024] Furthermore, the bending judgment component includes an inclination sensor, and the inclination sensor is fixedly connected to the top wall of the cavity.

[0025] The beneficial effects of the basic solution are: the inclination sensor can monitor the bending angle of the leg in real time, and convert tiny angle changes into electrical signals for transmission and processing, which helps the controller to quickly determine the bending state of the patient's legs, thereby controlling the position of the electromagnet and the change of magnetic force.

[0026] Furthermore, the hot compress assembly includes a heating wire and a temperature sensor. The heating wire is fixedly connected to the surface of the iron sheet, the temperature sensor is fixedly connected to the top wall of the cavity, the controller and the power supply are electrically connected to the heating wire, and the temperature sensor is signal-connected to the controller.

[0027] The beneficial effect of the basic solution is that the temperature sensor can monitor the temperature of the hot compress area in real time and transmit the temperature data to the controller, which is beneficial for the controller to adjust the temperature of the patient's hot compress in real time, improve the patient's comfort and the therapeutic effect on the patient's cartilage.

[0028] Furthermore, the cold compress assembly includes a water cooling pipe, both ends of which are connected to the outside.

[0029] The beneficial effects of the basic program are: cold compress can reduce the temperature of local tissues and reduce blood flow to the injured area, thereby effectively reducing inflammation and swelling. Supplementing cold water through the water cooling pipe is conducive to promoting the repair process of joint cartilage. The water cooling temperature is relatively mild and will not fluctuate violently, which is conducive to improving the patient's comfort when receiving cold compress treatment.

[0030] Furthermore, a circulation pump is provided in the water cooling pipeline, and the circulation pump is connected to the controller signal.

[0031] The beneficial effect of the basic solution is that the circulation pump can accelerate the circulation of cold water in the water cooling pipe, so that the cold water can absorb and take away the heat of the joint cartilage more quickly, thereby improving the cooling efficiency of the cold compress. Through the circulation of the circulation pump, the cold water can form a stable flow state in the water cooling pipe, which is conducive to reducing local overheating or overcooling and improving the effect of cold compress treatment.

[0032] Furthermore, the edge portions of the leg coverings are covered with flexible material.

[0033] The basic solution has the following beneficial effects: the flexible material can reduce the friction between the edge of the leg sleeve and the skin, reducing discomfort or skin abrasion during long-term wearing. At the same time, it can also effectively reduce the pressure of the leg sleeve on the blood vessels in the leg and promote blood circulation. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following is further described in detail through specific implementation methods:

[0040] Embodiment 1:

[0041] Basically as attached Figure 1-Figure 4 As shown: An auxiliary device for promoting articular cartilage repair, including a leg sleeve 1, both ends of the surface of the leg sleeve 1 are provided with binding components for binding the leg sleeve 1 to the patient's leg, and the binding components include a plurality of binding belts 2, and the binding belts 2 are sutured and connected to the leg sleeve 1. The leg sleeve 1 is provided with a binding component for binding the patient's leg, and the binding component includes an elastic binding belt 4, and the surface of the elastic binding belt 4 is provided with a plurality of first small holes, and the surface of the leg sleeve 1 is provided with second small holes at positions corresponding to the first small holes. A cavity is provided between the leg sleeve 1 and the elastic binding belt 4, and a power supply component is provided in the cavity; a controller 7 and a bending judgment component for judging the bending degree of the leg sleeve 1 are also provided in the cavity; the bending judgment component includes an inclination sensor 12, and the inclination sensor 12 is fixedly connected to the top wall of the cavity by bolts.

[0042] An electromagnet 8 and a gear 9 are provided in the cavity. A support rod is fixedly connected to one side of the electromagnet 8 by bolts. The end of the support rod away from the electromagnet 8 passes through the gear 9 and is slidably connected to the inner wall of the cavity. The support rod is rotatably connected to the gear 9. A driving member is slidably connected to the inner wall of the cavity. The output shaft of the driving member is fixedly connected to the gear 9. The driving member is preferably a motor. A rack 6 is meshed at the bottom of the gear 9, and the rack 6 is fixedly connected to the bottom wall of the cavity by bolts.

[0043] An iron sheet 5 for restoring the horizontal position of the leg cover 1 is also provided in the cavity, one end of the iron sheet 5 is fixedly connected to the inner wall of the cavity by bolts, and the other end of the iron sheet 5 is located on the same horizontal plane as the electromagnet 8. The power supply assembly includes a power supply, which is fixedly connected to the top wall of the cavity by bolts, and the controller 7 is connected to the power supply signal, and the power supply is electrically connected to the iron sheet 5.

[0044] The controller 7 is used to control the motor drive gear 9 to rotate and increase the magnetic force of the electromagnet 8 when the bending judgment component determines that the leg cover 1 is bent. When the bending judgment component determines that the leg cover 1 is not bent, the controller 7 controls the magnetic force of the electromagnet 8 to weaken.

[0045] The cavity also includes a buffer component for providing buffering for the iron sheet 5, and the buffer component includes a spring 3, one end of the spring 3 is fixedly connected to the inner wall of the cavity away from one end of the iron sheet 5 by bolts, and the other end of the spring 3 is fixedly connected to the iron sheet 5 by bolts.

[0046] The edge parts of the leg cover 1 are all covered with flexible material, and the flexible material is preferably made of cotton.

[0047] The specific implementation process is as follows: first, the patient needs to put the leg cover 1 and the elastic binding belt 4 on the leg, and then the patient binds the leg cover 1 on the leg through the binding belt 2, and ensures that the leg cover 1 fits tightly to the leg by adjusting the tightness of the binding belt 2.

[0048] At this time, the inclination sensor 12 starts to work. The inclination sensor 12 will continuously monitor whether the leg sleeve 1 is bent. When the patient's leg is bent, the leg sleeve 1 will bend accordingly. At this time, the inclination sensor 12 will transmit the angle data of the leg sleeve 1 to the controller 7. The controller 7 can control the motor to start according to the angle of the leg sleeve 1. The motor will drive the gear 9 to move forward or backward on the rack 6. Because one side of the electromagnet 8 is fixedly connected with a support rod by bolts, the other end of the support rod passes through the gear 9 and is slidably connected to the inner wall of the cavity, and the support rod is rotatably connected to the gear 9, so the gear 9 will drive the position of the electromagnet 8 to change forward or backward after moving forward or backward. The controller 7 will also control the power supply to increase the magnetic force of the electromagnet 8. The electromagnet 8 will continuously attract the iron sheet 5, and pull the iron sheet 5 to move during the adsorption process of the electromagnet 8, thereby straightening the leg sleeve 1.

[0049] When the electromagnet 8 attracts the iron sheet 5, the iron sheet 5 will continuously compress the spring 3. The buffering effect of the spring 3 enables the iron sheet 5 to generate a gentle supporting force when the leg cover 1 is stretched, thereby reducing the discomfort that may be caused by the strong attraction of the electromagnet 8 to the iron sheet 5.

[0050] When the inclination sensor 12 detects that the leg cuff 1 has returned to a horizontal position, the controller 7 controls the magnetic force of the electromagnet 8 to weaken through the power supply, and the iron sheet 5 remains stable under the buffering effect of the spring 3. At this time, the patient's leg joints always remain in a horizontal position, which helps the patient reduce the wear on the patient's leg joints and promotes the rehabilitation process of the patient's leg joints.

[0051] Because the power supply is electrically connected to the iron sheet 5, under the control of the controller 7, the power supply can release a weak current to the patient through the iron sheet 5, thereby performing electrotherapy on the patient's bone joints. Electrotherapy has an anti-inflammatory effect and can reduce the inflammatory response after articular cartilage damage. By reducing the infiltration of inflammatory cells and the release of inflammatory mediators, electrotherapy helps reduce joint swelling and pain, providing a better recovery environment for patients.

[0052] Embodiment 2:

[0053] The difference from the above embodiment is that: a cold compress component for providing a cold compress effect to the patient and a hot compress component for providing a hot compress effect to the patient are also provided in the cavity.

[0054] The hot compress assembly includes a heating wire 10 and a temperature sensor. The heating wire 10 is bonded to the surface of the iron sheet 5 by an adhesive. The temperature sensor is fixedly connected to the top wall of the cavity by bolts. The controller 7 and the power supply are electrically connected to the heating wire 10. The temperature sensor is signal-connected to the controller 7.

[0055] The cold compress assembly includes a water cooling pipe 11, both ends of which are connected to the outside. A circulating pump is arranged in the water cooling pipe 11, and the circulating pump is connected to the controller 7 by signal.

[0056] The specific implementation process is as follows: when the patient needs to apply heat to the leg joints, the patient can control the heating wire 10 to be powered on and heated through the controller 7. During the heating process of the heating wire 10, the heating temperature in the cavity is continuously monitored by the temperature sensor, and the controller 7 controls the power of the heating wire 10 through the power supply to maintain an appropriate temperature.

[0057] When the patient needs to apply cold compress to the leg joints, the patient can inject cold water into the water cooling pipe 11 through one end of the water cooling pipe 11, start the circulation pump through the controller 7, circulate the cold water in the water cooling pipe 11, accelerate the flow rate of the cooling water in the water cooling pipe 11, and thus improve the effect of the patient's cold compress.
