Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a modular ankle joint functional splint. Background Technology
[0002] Ankle ligament injuries are extremely common in orthopedic clinics. Patients often experience ankle pain and limited range of motion after an ankle sprain, which significantly impacts their quality of life. In traditional Chinese medicine, the treatment of limb fractures often involves the use of multiple functional splints for local fixation. This method, through the axial transmission mechanism of force, helps promote callus growth.
[0003] When using functional splint components to immobilize the ankle joint, the varying ages and growth patterns of patients lead to differences in leg length. Specifically, for patients with longer legs, the functional splint component, due to its fixed length, may not be able to achieve complete wrapping and fixation; while for patients with shorter legs, the functional splint component will extend beyond the edge of their leg, which not only affects aesthetics but, more importantly, hinders the patient's leg bending and other movements, thus reducing the general applicability of the functional splint component. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides the following technical solution: a modular ankle joint functional splint, comprising a first functional splint, a second functional splint, a third functional splint, and a fourth functional splint, wherein the first functional splint is internally slidably provided with an adjustment mechanism for adjusting the splint length; The adjusting mechanism includes a vertical slot, which is located on the front side of the first functional clamping plate. The vertical slot is movably engaged with the adjusting clamping plate. Connecting slots are located on both the left and right sides of the first functional clamping plate, communicating with the vertical slot. A limiting slot is located on the right side of the first functional clamping plate, communicating with the connecting slot. A connecting circular hole is located inside the adjusting clamping plate near the bottom, into which a movable circular rod is movably inserted. A cuboid limiting block is fixedly installed at the right end of the movable circular rod, movably engaging with the limiting slot. A fixing screw is fixedly installed at the left end of the movable round rod. The fixing screw is connected to a pressing nut by a thread. A malleable retaining strip is provided at the left end of the fixing screw. Before fixing the patient's ankle joint, the adjustment mechanisms in the first, second, third, and fourth functional splints adjust their respective lengths. When fixing the patient's ankle joint, they are initially fixed together to facilitate the wrapping of the bandage later. By adjusting the length of the first, second, third, and fourth functional splints, the functional splint assembly can be used for people with different leg lengths.
[0005] As an improvement to the above technical solution, there are multiple adjustment mechanisms. One side of the second functional clamp, the third functional clamp, and the fourth functional clamp are all provided with adjustment mechanisms. Through multiple adjustment mechanisms, the length of the second functional clamp, the third functional clamp, and the fourth functional clamp can be adjusted.
[0006] As an improvement to the above technical solution, the length of the first functional splint is greater than the length of the third functional splint, the length of the first functional splint is the same as that of the second functional splint, the length of the third functional splint is the same as that of the fourth functional splint, and the part of the first and second functional splints that is longer than the third functional splint is arc-shaped, which facilitates the first and second functional splints to fix the left and right sides of the patient's leg, and the third and fourth functional splints to fix the front and back sides of the patient's leg.
[0007] As an improvement to the above technical solution, the upper and lower sides of the limiting slot are designed to be inclined, which makes it easier for the cuboid limiting block to be locked in the limiting slot, and has a quantitative adjustment effect on the adjusting plate.
[0008] As an improvement to the above technical solution, there are two malleable clips. An assisting rod is fixedly installed on the right end of the cuboid limiting block, and another malleable clip is provided on the right end of the assisting rod. The malleable clips on both sides of the first functional clamp, the second functional clamp, the third functional clamp, and the fourth functional clamp are initially reinforced together by interlocking with each other.
[0009] The beneficial effects of this utility model are as follows: Before fixing the patient's ankle joint, the adjustment mechanisms in the first, second, third, and fourth functional splints adjust their respective lengths. When fixing the patient's ankle joint, they are initially fixed together, which facilitates the wrapping of the bandage later. By adjusting the length of the first, second, third, and fourth functional splints, the functional splint assembly can be used for people with different leg lengths, thereby enhancing the universal applicability of the functional splint assembly.

Detailed Implementation
[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.
[0013] Reference Appendix Figure 1 ,exist Figure 1 In the diagram, 'a' points to the front view and 'b' points to the right-side view. These views are only used to understand the scheme.
[0014] Please see Figure 1-5 This utility model provides a technical solution: a modular ankle joint functional splint, including a first functional splint 1, a second functional splint 11, a third functional splint 12 and a fourth functional splint 13, wherein the first functional splint 1 is internally slidably provided with an adjustment mechanism for adjusting the splint length. The adjustment mechanism includes a vertical slot 2, which is located on the front side of the first functional clamping plate 1. The vertical slot 2 is movably engaged with the adjustment clamping plate 21. The left and right sides of the first functional clamping plate 1 are provided with connecting slots 22, which are connected to the vertical slot 2. The right side of the first functional clamping plate 1 is provided with a limiting slot 23, which is connected to the connecting slot 22. The interior of the adjustment clamping plate 21 near the bottom is provided with a connecting round hole 24, which is movably inserted into the connecting round hole 24. A cuboid limiting block 26 is fixedly installed at the right end of the movable round rod 25, which is movably engaged with the limiting slot 23. A fixing screw 27 is fixedly installed at the left end of the movable round rod 25, which is connected to a pressing nut 28 by a thread. A plastic retaining strip 29 is provided at the left end of the fixing screw 27.
[0015] In this implementation scheme, before the patient's ankle joint is fixed, the adjustment mechanisms in the first functional splint 1, the second functional splint 11, the third functional splint 12 and the fourth functional splint 13 adjust their respective lengths. When fixing the patient's ankle joint, they are initially fixed together to facilitate the wrapping of the bandage later. By adjusting the lengths of the first functional splint 1, the second functional splint 11, the third functional splint 12 and the fourth functional splint 13, the functional splint assembly can be used for people with different leg lengths.
[0016] Specifically, there are multiple adjustment mechanisms, with adjustment mechanisms provided on one side of the second functional clamping plate 11, the third functional clamping plate 12, and the fourth functional clamping plate 13.
[0017] In this embodiment, the lengths of the second functional clamp 11, the third functional clamp 12, and the fourth functional clamp 13 can all be adjusted through multiple adjustment mechanisms.
[0018] Specifically, the length of the first functional clamp 1 is greater than the length of the third functional clamp 12. The lengths of the first functional clamp 1 and the second functional clamp 11 are the same. The lengths of the third functional clamp 12 and the fourth functional clamp 13 are the same. The portions of the first functional clamp 1 and the second functional clamp 11 that are longer than the third functional clamp 12 are arc-shaped.
[0019] In this embodiment, the first functional splint 1 and the second functional splint 11 are used to fix the left and right sides of the patient's legs, and the third functional splint 12 and the fourth functional splint 13 are used to fix the front and back sides of the patient's legs.
[0020] Specifically, the upper and lower sides of the card slot 23 are designed with an inclined shape.
[0021] In this embodiment, the cube-shaped limiting block 26 is easily locked in the limiting slot 23, which has a quantitative adjustment effect on the adjusting clamp 21.
[0022] Specifically, there are two malleable clips 29. An assist rod is fixedly installed on the right end of the cube-shaped limiting clip 26, and another malleable clip 29 is provided on the right end of the assist rod.
[0023] In this embodiment, the first functional clamp 1, the second functional clamp 11, the third functional clamp 12 and the fourth functional clamp 13 are initially reinforced together by interlocking the malleable clips 29 on both sides of the first functional clamp 1, the second functional clamp 11, the third functional clamp 12 and the fourth functional clamp 13.
[0024] In use, the first functional splint 1, the second functional splint 11, the third functional splint 12, and the fourth functional splint 13 are adjusted according to the patient's leg length. Pulling the adjusting splint 21 inside the first functional splint 1 moves it upward. The adjusting splint 21 drives the movable rod 25 upward through the connecting round hole 24. The movable rod 25 drives the cuboid limiting block 26 upward. The movable rod 25 drives the fixing screw 27 upward. The fixing screw 27 drives the pressing nut 28 and the malleable retaining strip 29 upward. When the adjusting splint... After 21 is moved to the appropriate length, rotate the pressing nut 28. Through the threaded connection with the fixing screw 27, the fixing screw 27 is moved to the left. The fixing screw 27 pulls the movable round rod 25 to the left. The movable round rod 25 pulls the cuboid limiting block 26 to the left and locks it into the nearest limiting slot 23. The limiting slot 23 quantitatively limits the length of adjustment of the adjusting clamp 21. The combination of the cuboid limiting block 26 and the pressing nut 28 and other structures completes the fixation of the adjusted adjusting clamp 21. Similarly, the second... The adjustment mechanisms within functional splints 11, 12, and 13 operate on the same principle as described above. Once the lengths of the first, second, third, and fourth functional splints 13 are determined, they are fixed to the patient's ankle joint and interlocked by the malleable locking strips 29 on both sides of each splint. The first functional splint 1, the second functional splint 11, the third functional splint 12, and the fourth functional splint 13 are initially reinforced together. At this point, the bandage can be easily wrapped around the first functional splint 1, the second functional splint 11, the third functional splint 12, and the fourth functional splint 13 to fix it. By adjusting the length of the first functional splint 1, the second functional splint 11, the third functional splint 12, and the fourth functional splint 13, the functional splint assembly can be used by people with different leg lengths, thereby enhancing the universal applicability of the functional splint assembly.
[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
