Technical Field

[0001] The utility model relates to the technical field of medical rehabilitation devices, in particular to a four-limb joint support structure. Background Art

[0002] The flat plate types of traditional cryoplastic plates and polymer splints have improper structural designs for stretching and bending at joint parts. The shaping process contour will interfere with the operation, and the structural stability after shaping is also insufficient. Among them, the straight plate structure of the polymer splint has obvious difficulties when encountering joint parts that need to be stretched and bent, and the bent part will bulge outward. For example, in the patent 201020209533.8, a medical polymer splint includes a plate-shaped polymer splint body with air holes densely distributed on the surface of the plate-shaped polymer splint body. It is quite troublesome to process, and the stability and reliability after fixation are worrying. The cryoplastic plate itself has good stretching effect and has a certain adhesiveness after being soaked in hot water, but it cannot ensure sufficient stability and reliability during the wearing process of patients. There will also be a fold angle at its bent part. For example, in the patent 202123040950.1, a comfortable cryoplastic plate and a cryoplastic plate brace include a cryoplastic plate body and a foam layer attached to at least one surface of the cryoplastic plate body. Moreover, the shaping process of this structure is cumbersome and needs to be adjusted frequently during the stretching process. This process is very painful for patients who are already injured.

[0026] The following will specifically describe the preferred embodiments of the present utility model in conjunction with the drawings. The drawings constitute a part of this application and are used together with the embodiments of the present utility model to explain the principle of the present utility model, rather than to limit the scope of the present utility model.

[0027] As shown Figure 1-2 in the figure, the utility model provides a limb joint support structure, which includes an upper support part 1, a lower support part 2 and a connecting part 3. The upper support part 1 and the lower support part 2 can be bent into an arc shape from both sides for fitting to the upper limb and the lower limb at the joint of the patient. The two ends of the connecting part 3 are respectively connected to the upper support part 1 and the lower support part 2 and are used for fitting to the joint position. The width of the connecting part 3 is smaller than that of the upper support part 1 and the lower support part 2, so that two grooves 101 are formed between the connecting part 3, the upper support part 1 and the lower support part 2. The two grooves 101 are distributed on both sides of the connecting part 3, so as to form a narrow and long section at the bending part of the joint. The connecting part 3 is used for fitting to the joint position. When bent, it is not easy to generate a large fold angle, so as to avoid the large impact of the fold angle on the support structure. Whether it is an easily stretchable material or a material with poor ductility is acceptable, thus reducing the limitation of the support structure in terms of material special features.

[0028] It can be understood that when the connecting part 3 is bent, since the grooves 101 cut off the connection between the upper support part 1 and the lower support part 2 at the bending parts on both sides, when the main body is bent into an arc shape and the connecting part 3 is bent to fold the two support parts at an angle, the upper support part 1 and the lower support part 2 will not affect each other, nor will they drive the connecting part 3 to generate an outward convex fold angle. The bending is easier, and the stretching or adjustment of the joint part can also be extremely simplified. Whether the material has sufficient ductility or not can meet the requirements. It can be applied to joint parts such as shoulder joints, elbow joints, and ankle joints.

[0029] It should be noted that the planar version of the limb joint support structure can be directly manufactured using a 3D printer.

[0030] In a certain embodiment, for the convenience of connection and fixation after bending, refer to Figure 1 and Figure 2 , two connecting wings 201 extend from the lower support part 2 towards the upper support part 1. The connecting wings 201 are located at the two side corners on this side. The connecting wings 201 respectively correspond to the two sides of the upper support part 1, and fixing parts 4 are arranged on the connecting wings 201 for connecting and fixing the positions of the upper support part 1 and the lower support part 2 which are bent into an arc shape when the connecting part 3 is bent to form an included angle between the upper support part 1 and the lower support part 2.

[0031] It can be understood that after the bending joint 3, there is an included angle between the upper support part 1 and the lower support part 2. Since the connecting wing 201 extends towards the upper support part 1, after bending, it partially overlaps the outer surface of the upper support part 1. At this position, the shape and included angle of this position can be fixed by passing the fixing member 4 through the connecting wing 201 and the upper support part 1; the fixing member 4 can be fixed by using a fixing buckle or a screw made of metal or non-metal, etc.

[0032] In one embodiment, in order to facilitate the adjustment of the bending angle after bending, refer to Figure 1 and Figure 2 The four - limb joint support structure further includes a pair of positioning structures 5. The positioning structure 5 includes an adjustment groove 51 and a positioning hole 52 formed on the upper support part 1. The shape of the adjustment groove 51 is arc - shaped, and several positioning holes 52 are distributed in a circular pattern with the center of the adjustment groove 51, mainly distributed in the upper part of the adjustment groove 51. Different bending angles are positioned according to different positioning holes 52; two through - holes 202 are formed on the connecting wing 201. When at the bending joint, the positions of the two through - holes 202 are respectively aligned with the corresponding adjustment groove 51 and the positioning hole 52 on the corresponding side. Guided by the adjustment groove 51, it can slide along the adjustment groove 51 for angle adjustment. The positioning hole 52 mainly plays a locking role. When sliding along the adjustment groove 51 to the required angle, the positioning hole 52 at the corresponding position is locked; the fixing member 4 is inserted into the through - hole 202. The fixing member 4 penetrates the through - hole 202, and is in a sliding connection within the adjustment groove 51. When the fixing member 4 penetrates the through - hole 202 and is within the positioning hole 52, since the positioning hole 52 does not provide a sliding range, the locking position is directly achieved to fix the angle.

[0033] It can be understood that during use, first install the fixing member 4 into the adjustment groove 51 and the corresponding through - hole 202. By sliding the fixing member 4 along the adjustment groove 51, the included angle between the upper support part 1 and the lower support part 2 is adjusted. Finally, at the required angle, install the fixing member 4 between the positioning hole 52 at this position and the aligned through - hole 202 to lock and position.

[0034] In one embodiment, in order to facilitate adjustment after bending, especially for the ankle part, to improve the strength of adjustment and connection, refer to Figure 5, the four - limb joint support structure further includes a pair of positioning structures 5. The positioning structure 5 includes a through - hole 202 and a fixing hole 53 opened on the upper support part 1, and an adjustment slot 51 and an engagement hole 54 opened on the connecting wing 201. A plurality of the fixing holes 53 are distributed in a multi - row array, specifically three rows and three columns. A plurality of the engagement holes 54 are distributed in an array, specifically three, and the array pitch is the same as the array pitch of the fixing holes 53, specifically three. By connecting different fixing holes 53 within the array range through the fixing member 4, the purpose of angle adjustment is achieved. And due to the structure fixed by the formed plurality of fixing members 4, the stability of the connection structure is improved. At the ankle, it is easy to swing inadvertently, so the controllability is improved specifically for this. When bending the connecting part 3, the adjustment slot 51 and the engagement hole 54 are respectively aligned with the corresponding through - hole 202 and the fixing hole 53 on the corresponding side; the fixing member 4 is inserted into the through - hole 202 and the engagement hole 54. Among them, the fixing member 4 passes through the adjustment slot 51 and the through - hole 202 and can slide within the adjustment slot 51, so as to perform angle adjustment. The fixing member 4 passes through the fixing hole 53 and the corresponding engagement hole 54, so as to fix the angle.

[0035] It can be understood that the adjustment slot 51, the engagement hole 54, the through - hole 202 and the fixing hole 53 on the positioning structure 5 of the upper support part 1 and the lower support part 2 can be swapped up and down. As long as when bending, the adjustment slot 51 is aligned with the through - hole 202, and the engagement hole 54 is aligned with the fixing hole 53.

[0036] In a certain embodiment, in order to facilitate locking and positioning, the fixing member 4 can adopt a rivet snap 401. The snap of the rivet snap 401 has two ends. The snap is positioned within the hole slots to be inserted, thus forming a positioning. Specifically, no matter which end of the rivet snap 401 it is, the diameter of the penetration position is smaller than the inner diameter of the hole slot, and its head fits to both ends of the hole slot, and its head is larger than the inner diameter of the hole slot.

[0037] It can be understood that the rivet snap 401 is an existing fixing snap. Its structure consists of an A - end and a B - end. The A - end and the B - end respectively correspond to the snap seat and the snap head. When engaging, it can form a connection, so that after passing through two holes, it can be engaged again, thus connecting the upper support part 1 and the lower support part 2.

[0038] In a certain embodiment, in order to be bound to the patient's limb, refer to Figure 1 and Figure 3, a plurality of pairs of binding ends 6 are provided on both the upper supporting part 1 and the lower supporting part 2. The binding ends 6 include a U-shaped groove 61 and a through groove 62. The U-shaped groove 61 is provided on the upper supporting part 1 or the lower supporting part 2, and an outward convex wing 601 is formed in the U-shaped groove 61. The through groove 62 is provided on the outward convex wing 601.

[0039] It can be understood that due to the characteristics of the flat pattern, when bent, since the outward convex wing 601 is separated by the U-shaped groove 61 and does not produce linkage, it will come out of the U-shaped groove 61 and turn outwards, thus being exposed. Furthermore, when installing the binding strap, it is convenient for installation.

[0040] Furthermore, a binding strap 8 is provided between a pair of the binding ends 6. The binding strap 8 passes through and is sleeved between the through grooves 62 on a pair of the binding ends 6, thereby forming an annular binding relationship.

[0041] Furthermore, the binding strap 8 is a Velcro strap, which is convenient for binding and disassembling.

[0042] In one embodiment, in order to improve breathability and comfort, refer to Figure 4 , a plurality of ventilation holes 7 are provided on both the upper supporting part 1 and the lower supporting part 2. The ventilation holes 7 are distributed in a honeycomb shape on both the upper supporting part 1 and the lower supporting part 2, thereby improving the overall breathability and comfort.

[0043] Furthermore, refer to Figure 1 , a soft pad 301 is provided on the connecting part 3 for being padded at the joint, thereby improving the softness of the contact at the joint and reducing the discomfort at the joint.

[0044] The specific working process of the present utility model: When in use, bend both sides of the upper supporting part 1 and the lower supporting part 2, and push the upper supporting part 1 and the lower supporting part 2 to bend the connecting part 3, so that an included angle is formed between the upper supporting part 1 and the lower supporting part 2, and the connecting wing 201 is attached to the outer surface of the upper supporting part 1, align the adjusting groove 51 with the corresponding through hole 202, and penetrate the fixing member 4 between them. Then slide and adjust to align the through hole 202 above it with the corresponding positioning hole 52, and penetrate the fixing member 4 between them to lock it. The point-to-point flat structure simplifies the process of manual shaping, with few actions and high speed.

[0045] The entire working process ends, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0046] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
