Description

Technical Field

[0001] The present invention relates to the technical field of knee joint cartilage, and particularly to a knee joint cartilage repair and fixation bracket. Background Art

[0002] The knee joint cartilage covers the surface of the knee joint bone end and is a layer of transparent cartilage, like a "protective pad of the joint". Its surface is smooth, and it is rich in water and collagen inside. Common lesions of the knee joint cartilage include wear and degeneration, traumatic injury and inflammatory lesions. The repair methods for cartilage lesions include drug treatment, physical therapy, rehabilitation training and surgical treatment.

[0003] During the use of the existing knee joint cartilage repair and fixation bracket, it is impossible to adjust the required length of the bracket according to the height of the patient, resulting in poor fixation effect and affecting the repair progress of the knee joint cartilage. Therefore, we propose a knee joint cartilage repair and fixation bracket. Summary of the Invention

[0004] In view of the above problems, the present invention provides a knee joint cartilage repair and fixation bracket, which can conveniently and quickly adjust the required length of the bracket.

[0005] The technical solution of the present invention is as follows: A knee joint cartilage repair and fixation bracket includes a first fixing plate. A second fixing plate is installed at the bottom end of the first fixing plate. One ends of the first fixing plate and the second fixing plate are both fixedly connected with connecting arc plates. One end of the connecting arc plate is installed with an elastic band. The connecting arc plate and the elastic band form an annular structure that can be sleeved on the leg. A slot is opened at one end of the first fixing plate close to the second fixing plate. A telescopic plate is fixedly installed at one end of the second fixing plate close to the first fixing plate. The telescopic plate is inserted into the slot and fixed by a positioning component.

[0006] In a further technical solution, the positioning component includes two positioning pins threadedly connected to the outside of the first fixing plate. Positioning grooves are opened on the outside of the telescopic plate. A positioning soft pad is installed inside the positioning grooves. The positioning pins penetrate through the inside of the first fixing plate and contact the positioning soft pad. Movable convex blocks are fixedly installed on both sides of the top end of the telescopic plate.

[0007] In a further technical solution, a limiting band is sewn and connected to the outside of the elastic band. The other end of the limiting band is sewn and connected with a button hole. A plurality of button surfaces are installed at one end of the outside of the connecting arc plate. The button hole can be respectively buckled with the plurality of button surfaces.

[0008] In a further technical solution, storage grooves for placing items are opened on the inner sides of the first fixing plate and the second fixing plate.

[0009] In a further technical solution, both the first fixing plate and the second fixing plate are designed in an arc shape, and chamfers are provided on the end faces of the first fixing plate and the second fixing plate.

[0010] The beneficial effects of the present invention are as follows: Compared with the prior art, by designing the telescopic plate to move in the slot, the distance between the first fixing plate and the second fixing plate can be increased or decreased, so as to be suitable for the use of different people. At the same time, the positioning component is used for fixation, with high stability, simple operation of the fixation method, and can better reduce the activity force of the patient; By sleeving the ring structure on the leg and then pulling the limiting belt, the button hole on the limiting belt is buckled on the corresponding button surface, so that the size of the ring structure can be changed to adapt to the legs of different people, improving the applicability of the device and enabling the device to be worn quickly; Through the provided storage groove, some medicated patches and other items can be put in to treat the patient's leg; By providing chamfers on both side end faces of the first fixing plate and the second fixing plate, the device can be prevented from scratching the leg and the comfort of the device can be improved.

[0013] The following further describes the embodiments of the present invention with reference to the drawings. Embodiment

[0014] As Figures 1-4As shown in the figure, a knee joint cartilage repair and fixation bracket includes a first fixing plate 1. A second fixing plate 2 is installed at the bottom end of the first fixing plate 1. One ends of the first fixing plate 1 and the second fixing plate 2 are both fixedly connected with connecting arc plates 3. An elastic band 4 is installed at one end of the connecting arc plate 3. The connecting arc plate 3 and the elastic band 4 form an annular structure that can be sleeved on the leg. A slot is opened at one end of the first fixing plate 1 close to the second fixing plate 2. A telescopic plate 7 is fixedly installed at one end of the second fixing plate 2 close to the first fixing plate 1. The telescopic plate 7 is inserted into the inside of the slot and fixed by a positioning component. Two positioning pins 6 are threadedly connected to the outside of the first fixing plate 1. A positioning groove 13 is opened on the outside of the telescopic plate 7. A positioning soft pad 14 is installed inside the positioning groove 13. The positioning pin 6 penetrates through the inside of the first fixing plate 1 and contacts the positioning soft pad 14. Movable convex blocks 12 are fixedly installed on both sides of the top end of the telescopic plate 7.

[0015] In another embodiment, as Figure 1 and Figure 3 shown, a limiting band 5 is sewn and connected to the outside of the elastic band 4. The other end of the limiting band 5 is sewn and connected with a buttonhole 10. A plurality of button surfaces 11 are installed at one end of the outside of the connecting arc plate 3. The buttonhole 10 can be respectively buckled with the plurality of button surfaces 11. By sleeving the annular structure on the leg and then pulling the limiting band 5, the buttonhole 10 on the limiting band 5 is buckled on the corresponding button surface 11, so that the size of the annular structure can be changed to adapt to the legs of different people, improving the applicability of the device and enabling the device to be worn quickly.

[0016] In another embodiment, as Figure 2 shown, storage grooves 8 for placing items are opened on the inner sides of the first fixing plate 1 and the second fixing plate 2. Through the provided storage grooves 8, some medical patches and other items can be put in to treat the patient's leg.

[0017] In another embodiment, as Figure 2 shown, the first fixing plate 1 and the second fixing plate 2 are both designed in an arc shape. Chamfers 9 are provided on the end faces of the first fixing plate 1 and the second fixing plate 2. By providing chamfers 9 on both side end faces of the first fixing plate 1 and the second fixing plate 2, it can prevent the device from scratching the leg and improve the comfort of the device.

[0018] The working principle of this application is as follows: By putting two ring structures on the leg, first pull the limit band 5 on one end of the ring structure, so that the elastic band 4 is tightened. Then buckle the button hole 10 on the limit band 5 onto the corresponding button surface 11. Then pull the second fixing plate 2, so that the second fixing plate 2 drives the telescopic plate 7 to move in the slot. Then by turning the two positioning pins 6, the positioning pins 6 move towards the inside of the first fixing plate 1, so that one end of the positioning pin 6 contacts the positioning soft pad 14 and squeezes the positioning soft pad 14. At this time, the telescopic plate 7 is fixed by the two positioning pins 6, and the ring structure at one end of the second fixing plate 2 can be fixed and tightened, thus completing the wearing of the device.

[0019] The above embodiments only represent the specific implementation manners of the present invention, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
