Description

Technical Field

[0001] This utility model relates to the field of orthotics technology, and in particular to a buffer and noise reduction component for orthotics. Background Technology

[0002] As a medical device used to correct or assist human motor function, the structural design of orthoses directly affects patient comfort and treatment effectiveness. Traditional lower limb orthoses typically employ a split design, consisting of a foot brace and a calf brace connected by a rigid or flexible joint. While this split structure provides freedom of joint movement and support, it also has some technical drawbacks. During walking or exercise, the connection between the foot brace and calf brace experiences relative displacement due to movement, leading to mechanical impact. This impact not only generates instantaneous force, causing discomfort, but also produces noticeable noise, potentially causing psychological stress and resistance in patients with prolonged use. To alleviate these problems, existing technologies commonly employ buffering and noise-absorbing components. For example, through-holes or grooves are created in the contact area between the foot brace and calf brace, with cylindrical cushioning pads inserted into these holes / grooves to absorb impact energy.

[0003] However, the cushioning structure of traditional lower limb orthoses is prone to contradictions between material hardness, assemblability, and cushioning performance. Soft materials are prone to deformation and failure and are difficult to assemble, while hard materials are easy to assemble but have insufficient impact absorption capacity. Utility Model Content

[0004] In view of this, the present invention provides a buffer and noise reduction component for orthotics, which solves the problem that the buffer structure of orthotics in the prior art is prone to contradiction between material hardness and assemblability and buffer performance. Soft materials are prone to deformation and failure and are difficult to assemble, while hard materials are easy to assemble but have insufficient impact absorption capacity.

[0005] To achieve one, some, or all of the above objectives, or other objectives, this utility model proposes a buffer and noise reduction assembly for an orthopedic device, comprising two support plates movably connected together, and each of the adjacent ends of the support plates having an installation groove that connects to its end wall. A buffer block is fixedly placed in each of the installation grooves, and at least one of the buffer blocks extends beyond the end wall of the corresponding support plate. When the adjacent ends of the two support plates move closer together, the two buffer blocks can abut against each other to buffer the impact.

[0006] Preferably, the distance between the inner walls on both sides of the mounting groove gradually decreases from the inner side of the support plate to the inner wall of the mounting groove, and the outline of the buffer block matches the mounting groove.

[0007] Preferably, the orthotics' buffer and noise reduction assembly further includes a connector, and the buffer block and the support plate are rigidly connected through the connector.

[0008] Preferably, the connector includes a nut and a screw, the outer side of the support plate has a first through hole for connecting the mounting groove, the buffer block has a second through hole corresponding to the first through hole, the nut is located on the exposed side of the buffer block, the head of the screw abuts against the outer wall of the support plate, and its tip passes through the first through hole and the second through hole and is screwed into the nut.

[0009] Preferably, the exposed side of the buffer block has a receiving groove that connects to the second through hole, and the nut is placed in the receiving groove.

[0010] Preferably, the nut is provided with teeth to limit its slippage and rotation.

[0011] Preferably, one of the buffer blocks has a spherical protrusion at one end, which can abut against the end of the other buffer block when the adjacent ends of the two trays move closer together.

[0012] Preferably, the orthotics' buffer and noise reduction assembly further includes two flexible pads, which are fixedly laid on the exposed side of the buffer block and flush with the inner sidewall of the corresponding support plate.

[0013] Preferably, the orthotics' buffer and noise reduction assembly further includes a molding block. When two of the buffer blocks abut against each other, the two mounting slots connect to form a cavity, and the contour of the cavity matches the molding block.

[0014] Preferably, both ends of the molded block are provided with positioning holes that penetrate its inner and outer side walls.

[0015] Implementing the embodiments of this utility model will have the following beneficial effects:

[0016] After adopting the aforementioned orthotic cushioning and noise-absorbing components, during use, one of the support plates has a contour that adapts to the heel and Achilles tendon area. Its lower end can be bent forward to form a structure similar to a shoe sole to support the user's foot and can be fixed to the foot with straps, so that the corresponding support plate is attached to the user's heel. The contour of the other support plate adapts to the lower half of the calf muscle. During use, this support plate is attached to the calf muscle. Similarly, its two ends in the circumferential direction can be connected by straps, so that it can be fitted onto the adjacent calf (not shown in the attached figure). When the foot and calf are in contact... When the two plates swing to a certain angle, such as 90 degrees, the adjacent ends of the two plates tend to collide. At this time, the two buffer blocks can replace the two plates to abut against each other, absorb the impact energy, reduce the noise generated by the collision, and play a soundproofing role. Compared with the traditional plug-in method, the buffer blocks of this application can be directly inserted into the mounting groove on the inner side of the plate. The mounting groove is compatible with the installation of buffer blocks of any hardness. This solves the problem that the buffer structure of traditional lower limb orthotics is prone to contradiction between material hardness and assembly and buffer performance, reduces the assembly difficulty, and makes the selection of buffer block materials more flexible.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] like Figure 1-5 As shown, a cushioning and noise reduction assembly for an orthosis includes two support plates 1, which are movably connected. Each adjacent end of a support plate 1 has an inner mounting groove 11 that connects to its end wall. A buffer block 2 is fixedly placed within each mounting groove 11. At least one buffer block 2 extends beyond the end wall of the corresponding support plate 1. When the adjacent ends of the two support plates 1 move closer together, the two buffer blocks 2 can abut against each other to cushion the impact. It is understood that this invention can be applied to any limb connected by a joint. (Refer to...) Figure 4 Taking the feet and calves as examples, when using it, it is located in... Figure 4 The lower support plate 1 is contoured to fit the heel and Achilles tendon area. Its lower end can be bent forward to form a structure similar to a shoe sole to support the user's foot. Its lower end can be secured to the foot with straps, so that the corresponding support plate 1 is attached to the user's heel. Figure 4The outline of the other support plate 1 above is adapted to the lower half of the calf. When in use, the support plate 1 is attached to the calf. Similarly, its two ends in the circumferential direction can be connected by straps so that it can be fitted onto the adjacent calf (not shown in the figure). When the foot and calf swing relative to each other to a certain angle, such as 90 degrees, the adjacent ends of the two support plates 1 tend to collide. At this time, the two buffer blocks 2 can replace the two to abut against each other, absorb the impact energy, reduce the noise generated by the collision, and play a soundproofing role. Moreover, compared with the traditional plug-in method, the buffer block 2 of this application can be directly inserted into the mounting groove 11 on the inner side of the support plate 1. The mounting groove 11 is compatible with the installation of buffer blocks 2 of any hardness, which solves the problem that the buffer structure of traditional lower limb orthotics is prone to contradiction between material hardness and assembly and buffer performance, reduces the assembly difficulty, and makes the selection of materials for buffer blocks 2 more flexible.

[0029] In one embodiment, the orthotic cushioning and noise reduction assembly can be used on the arm, with one support plate 1 fixedly attached to the outside of the forearm by straps and the other support plate 1 fixedly attached to the outside of the upper arm by straps.

[0030] Specifically, the two support plates 1 can be connected by a linkage mechanism and move relative to each other within a fixed range to accommodate the user's limb movements; the buffer block 2 can be fixed in the mounting groove 11 by one or more methods such as plugging, gluing, or screw 4; the buffer block 2 can be made of any material with a hardness of Shore A 55° or higher, preferably Shore A 65-85°.

[0031] Furthermore, the distance between the inner walls on both sides of the mounting groove 11 gradually decreases from the inner side of the support plate 1 to the inner wall of the mounting groove 11, making the cross-section of the mounting groove 11 trapezoidal. The outline of the buffer block 2 matches the mounting groove 11, so that the buffer block 2 can be easily inserted into the mounting groove 11 during installation. This not only further reduces the installation difficulty of the buffer block 2, but also improves the connection strength between the inner wall of the mounting groove 11 and the buffer block 2, thereby enhancing the installation stability of the buffer block 2.

[0032] Furthermore, the orthotics' buffer and noise reduction assembly also includes a connector. The buffer block 2 and the support plate 1 are rigidly connected by the connector. The connector can be a bolt. A screw hole can be pre-set on the buffer block 2. The bolt passes through the support plate 1 and screws into the screw hole to tighten the buffer block 2 onto the inner wall of the mounting groove 11 (not shown in the attached figure).

[0033] Furthermore, the connector includes a nut 3 and a screw 4. The outer side of the support plate 1 has a first through hole 12 that connects to the mounting groove 11. The buffer block 2 has a second through hole 21 corresponding to the first through hole 12. The nut 3 is located on the exposed side of the buffer block 2. The head of the screw 4 abuts against the outer wall of the support plate 1, and its tip passes through the first through hole 12 and the second through hole 21 and is screwed into the nut 3. Thus, by tightening the screw 4, the head of the nut 3 and the screw 4 clamps the buffer block 2 onto the inner wall of the mounting groove 11. When the two buffer blocks 2 collide, the screw 4 and the side wall of the mounting groove 11 will provide support for the buffer block 2, ensuring the installation stability of the buffer block 2.

[0034] Furthermore, the exposed side of the buffer block 2 is provided with a receiving groove 22 that connects to the second through hole 21. The nut 3 is placed in the receiving groove 22 to keep the exposed surface of the buffer block 2 flat, avoid the feeling of foreign objects caused by the nut 3 protruding and contacting the limbs, and improve the user experience.

[0035] Furthermore, the nut 3 is provided with teeth (not shown in the attached figure) to limit its slippage and rotation, so as to increase the frictional resistance between the nut 3 and the exposed side of the buffer block 2, prevent the nut 3 from easily rotating and loosening after the screw 4 is tightened, and improve the installation stability of the nut 3.

[0036] Furthermore, one end of a buffer block 2 is provided with a spherical protrusion 23. In this embodiment, there are two spherical protrusions 23. When the adjacent ends of the two support plates 1 move closer together, the spherical protrusion 23 can abut against the end of another buffer block 2. This reduces the contact area when the two buffer blocks 2 collide. When the material hardness is appropriate, it increases the local pressure during the impact, allowing the impact end of the buffer block 2 to enter plastic deformation more quickly, consuming more energy and reducing the proportion of vibration energy converted into sound energy, thereby reducing noise. At the same time, a small contact area easily induces high-frequency vibration, and high-frequency sound waves attenuate faster in the air, which can reduce the propagation distance and perceived noise within a certain range, further improving the noise reduction effect.

[0037] Furthermore, the orthodontic cushioning and noise reduction assembly also includes two flexible pads 5. The flexible pads 5 can be made of foam or silicone. The flexible pads 5 are fixedly laid on the exposed side of the buffer block 2 and flush with the inner wall of the corresponding support plate 1 to cover the nut 3 and the buffer block 2. The flexible pads 5 serve as an extension of the inner wall of the support plate 1, keeping the inner wall of the support plate 1 flat and improving the wearing comfort of the support plate 1.

[0038] like Figure 5 As shown, the orthotics' buffer and noise reduction assembly further includes a molding block 6. When the two buffer blocks 2 abut against each other, the two mounting grooves 11 are connected to form a cavity. The contour of the cavity matches the molding block 6. Both ends of the molding block 6 are provided with nail holes 61 that penetrate its inner and outer side walls.

[0039] Furthermore, positioning holes 62 are provided at both ends of the molding block 6, penetrating its inner and outer side walls.

[0040] The forming block 6 is used to help the support plate 1 form. Taking a foot and lower leg orthosis as an example, the operation steps are as follows:

[0041] 1) First, fix the molding block 6 onto the lower leg model (either by gluing or by inserting long nails 7 into the nail holes 61 to fix the molding block 6 onto the lower leg model);

[0042] 2) Cover the heated sheet material onto the leg model with the molding block 6 installed, and vacuum-form it;

[0043] 3) Trim and shape the formed blank;

[0044] 4) Remove the forming block 6 from the lower leg model and place it into the trimmed blank. Drill the first through hole 12 on the blank according to the positioning hole 62 on the forming block 6.

[0045] 5) Cut the blank at the ankle position to form two support plates 1, which will be used as foot supports and calf supports respectively.

[0046] Thus, the forming block 6 is used to make the pallet 1, help the mounting groove 11 to be formed, assist the operator in drilling the first through hole 12, reduce the positioning difficulty of the first through hole 12, and improve the processing efficiency of the pallet 1.
