Description

Technical Field

[0001] The utility model relates to the technical field of medical protective gear, in particular to a postoperative cruciate ligament protector. Background Art

[0002] Cruciate ligament protectors are typically wearable devices that use materials such as elastic fabric, nylon, and hook-and-loop straps to provide structural support and stability. They are typically secured around the joint and compress the ligaments, reducing range of motion and thus preventing overextension or injury.

[0003] After searching, the existing Chinese patent (publication number: CN215994432U) discloses a rehabilitation brace after posterior cruciate ligament reconstruction, including a thigh strap and a calf strap, the back of the thigh strap is fixedly connected to a first support shaft, the back of the calf strap is fixedly connected to a second support shaft, the bottom of the first support shaft and the top of the second support shaft are penetrated by the connecting shaft. The utility model is provided with a first support shaft, a second support shaft, a fixed shell and a connecting shaft, so that the patient wearing the brace can bend the knee more easily and conveniently. The first support shaft and the second support shaft are rotatably connected by the connecting shaft, and it is more convenient for the patient to bend the knee. The fixed shell is moved between the two, and then the first threaded hole and the second threaded hole are threadedly connected by a fixing nut to fix it. The first support shaft and the second support shaft cannot rotate, and the patient's legs are fixed more firmly.

[0004] The above-mentioned ligament protector adopts a solution in which the first support shaft and the second support shaft are rotatably connected by a connecting shaft to solve the technical solution that is very inconvenient for patients to use the toilet and do rehabilitation training when bending their knees. However, when this solution is fixed by threads, patients with limited mobility need to rely on the help of others and use tools for disassembly and installation, which involves finding suitable tools, explaining the correct operating steps and relying on the assistance of others. It is extremely inconvenient and reduces independence. Therefore, we propose a postoperative cruciate ligament protector to solve the above problem. Utility Model Content

[0005] The utility model provides a cruciate ligament protector after surgery, which solves the technical problem that the current ligament protector is inconvenient to disassemble.

[0006] To solve the above technical problems, the present invention provides a postoperative cruciate ligament protector, comprising a support assembly, wherein both ends of the support assembly are fixedly connected to the outer sides thereof with elastic assemblies, the top end of the elastic assemblies is fixedly connected to a connecting assembly, one side of the connecting assembly is fixedly connected to a protecting assembly, and the side of the protecting assembly close to the support assembly is fixedly connected to a thermostatic assembly;

[0007] The tensioning assembly includes a chassis, which is provided with four chassis. One end of the inner wall of the chassis is rotatably connected to a ratchet, and the end of the chassis away from the ratchet is rotatably connected to a handle. The bottom end of the inner wall of the chassis is rotatably connected to a rotating column, and the outside of the rotating column is fixedly connected to a pawl, and the pawl is engaged with the ratchet. The rotating column passes through the chassis and extends outward.

[0008] The above technical solution adopts the following: the support assembly primarily provides the basic structure of the ligament protector, providing stability and support. Elastic components are fixedly connected to the outer sides of both ends of the support assembly. This design enhances the flexibility and adaptability of the protector. The connecting component primarily facilitates the assembly and connection of the entire ligament protector. The protective component primarily wraps and protects the affected area, preventing postoperative ligament damage or contamination from the external environment, thereby ensuring smooth postoperative recovery. It also helps provide a certain degree of compression to help reduce swelling and alleviate pain. The thermostat component primarily maintains a stable temperature in the affected area to avoid sudden pain, irritation, or decreased comfort caused by temperature differences. Furthermore, proper temperature control helps promote blood circulation, thereby accelerating recovery. The chassis is the foundation of the entire elastic component. The structure is equipped with a total of four chassis, which provide better stability and support for the entire protector. One end of its inner wall is rotatably connected to a ratchet, which can adjust and redirect the force transmission, allowing for greater flexibility of the elastic component. A handle is rotatably connected to the end of the chassis away from the ratchet. The handle primarily provides a manual operation interface, allowing the user to manually adjust the tightness of the elastic component so that the protector can be adjusted according to the specific rehabilitation needs of the postoperative patient. The bottom end of the inner wall of the chassis is rotatably connected to a rotating column. This design further realizes the transmission of power. The external fixed connection of the rotating column is connected to a pawl, which engages with the ratchet. This mechanical design achieves force amplification and stable output, making the adjustment of the entire protector smoother and more precise. The rotating column not only rotates inside the chassis, but also penetrates the chassis and extends outward. With this setting, the rotating column can more flexibly control the ratchet.

[0009] Preferably, the connecting assembly includes a disc, one end of the disc is fixedly connected to the ratchet, the inner wall of the disc is fixedly connected to an elastic rope, the end of the elastic rope away from the chassis is fixedly connected to a fixed column, and the end of the disc away from the ratchet is fixedly connected to the handle.

[0010] Using the above technical solution, one end of the disc is fixedly connected to the ratchet. This design allows the disc to further transmit power through the rotation of the ratchet. The elastic cord is used to adjust the pressure and tension of the protector as needed. In addition, the end of the elastic cord away from the chassis is fixedly connected to a fixed column. The fixed column transmits force more evenly to various parts of the protector through the elastic cord. The end of the disc away from the ratchet is fixedly connected to the handle, which can be manually controlled by the user. Therefore, this design allows users to manually adjust the pressure and tension of the protector according to their needs.

[0011] Preferably, the support assembly includes a lower support frame, one end of the lower support frame is fixedly connected to a connecting belt 1, and the end of the connecting belt 1 away from the lower support frame is fixedly connected to an upper support frame, wherein the adjacent sides of the two chassis are fixedly connected to the lower support frame, and the adjacent sides of the other two chassis are fixedly connected to the upper support frame.

[0012] The above technical solution is adopted: one end of the lower support frame is fixedly connected with a connecting belt 1. This design allows the lower support frame to be linked with the upper support frame with the help of the connecting belt 1 to form a stable overall structure. The support frame is pulled by the connecting belt 1 and forms a stable structure with the lower support frame. In this way, the structure of the entire equipment is more stable and can provide a stable base during operation. The adjacent sides of the two chassis are respectively fixed on the lower support frame and the upper support frame. This design allows the chassis to drive the lower support frame and the upper support frame as needed to achieve functional adjustment of the equipment.

[0013] Preferably, the protection component includes a protective pad 1, two of which are provided, and the adjacent sides of the two protective pads 1 are fixedly connected to a connecting belt 2, the adjacent sides of the two connecting belts 2 are fixedly connected to the protective pad 2, and the adjacent sides of the fixing columns are fixedly connected to the protective pad 1.

[0014] Using the above technical solution, pad 1 provides basic protection, providing initial shock absorption and wear resistance. Connecting strap 2 is fixedly attached to the adjacent sides of the two pads. This indicates that pads 1 are connected by connecting strap 2. Pad 2 provides protection on the outer side of pad 1, providing a double layer of protection. Pad 1 is also fixedly attached to a fixing post, which provides additional stability to the equipment.

[0015] Preferably, the constant temperature assembly includes an insulation block, a graphene heating plate, a spacer, and a silicone gasket. The end of the insulation block away from the spacer is fixedly connected to the second pad, and the end of the silicone gasket away from the lower support frame is on the first pad. The insulation block is made of polyethylene foam material, the graphene heating plate is fixedly connected between the insulation block and the spacer, and the spacer is made of velvet material.

[0016] The above technical solution is adopted: the insulation block is made of polyethylene foam material, which is a commonly used insulation material with low thermal conductivity. It can effectively block the intrusion of external hot and cold air and reduce internal temperature fluctuations. The graphene material has excellent electrothermal properties and can quickly increase the temperature by powering on. The spacer is made of velvet material, which plays an isolation role, isolating the part of the equipment in contact with the insulation block and the graphene heating plate from the skin of the leg to avoid direct contact. The design of the silicone gasket plays an anti-slip and shock-absorbing role.

[0017] Preferably, the elastic component and the connecting component are symmetrically arranged, the groove opened on the disc is adapted to be connected to the outside of the elastic rope, the inner wall shape of the upper support frame and one of the pads fits the contour of the human thigh, and the inner wall shape of the lower support frame and the other pad fits the contour of the human calf.

[0018] The above technical solution uses a groove on the disc that fits the outside of the elastic cord. This design allows the elastic cord to easily engage with the disc when the device needs to be resized. When tightening or loosening it, it can slide freely in the groove, making the device easier to use and adjust. The upper and lower support frames are designed to conform to the contours of the human thigh and calf, increasing user comfort while reducing discomfort. The ergonomic design also improves device performance, enabling it to achieve better results during use.

[0019] Compared with the related art, the present invention has the following beneficial effects:

[0020] 1. Compared with traditional ligament protectors, the present invention sets a support component, an elastic component, a connection component, and a protection component. The user turns the handle by hand to drive the disc to tighten the elastic rope, so that the lower support frame, the upper support frame, and the first and second pads fit the legs, so that the injured part will gradually recover during the rehabilitation process. By being able to adjust the tightness of the protector, the support for the joints or ligaments can be gradually reduced, helping patients adapt to the gradually enhanced muscle and joint stability, and greatly reducing the time and process of adjustment.

[0021] 2. In the present invention, by setting a constant temperature component, when the patient wears the protector, the constant temperature device will fit the knee, and the graphene material of the graphene heating sheet provides a certain amount of heat to achieve a constant temperature effect. In addition, the silicone gasket has good elasticity, which can buffer the vibration of bones and muscles, reduce pain, improve comfort, help relieve symptoms, and facilitate postoperative recovery.

Synchronously, the ratchet 202 drives the rotating column 205 to rotate, so that the pawl 204 fixed on the rotating column 205 moves synchronously and regularly. This movement is transmitted to the disc 301 connected to the ratchet 202 through the ratchet 202. At this time, the handle 203 is still in operation, thereby also causing the disc 301 to rotate, and the rotation of the disc 301 drives the movement of the elastic cord 302 through the adaptive connection between the groove and the elastic cord 302. Next, the movement of the elastic cord 302 The fixing column 303 fixed thereon is driven to move, and this movement changes the pressure and tightness of the ligament protector. Since the fixing column 303 is fastened to the pad 401, the changed pressure and tightness will be transmitted to the pad 401, further acting on the user's ligament area. At the same time, the upper support frame 103 and the lower support frame 101 are designed to fit the contours of the human thigh and calf, which increases the comfort of the device user and can adjust the pressure and tightness of the protector according to the user's physical condition and rehabilitation needs. While providing protection, the constant temperature component 5 composed of the insulation block 501, the graphene heating plate 502, the spacer 503, and the silicone gasket 504 maintains the stability of the internal environment of the ligament protector, avoids sudden pain caused by external temperature difference, and provides a good rehabilitation environment.
