Description

Technical Field

[0001] This application relates to the field of rehabilitation technology, and more specifically, to a rehabilitation aid for finger flexor tendons. Background Technology

[0002] In clinical practice, patients with finger flexor tendon injuries generally require 4 to 6 weeks of immobilization after surgical treatment. Because immobilization inevitably leads to tendon adhesions, they are unable to make a fist and their daily activities will be severely affected.

[0003] Currently, finger flexion training is the best rehabilitation therapy for improving flexor tendon adhesions. The finger flexor tendons are divided into the superficial flexor digitorum superficialis tendons and the deep flexor digitorum deepis tendons. The superficial flexor digitorum superficialis tendons control the flexion of the proximal interphalangeal joints, while the deep flexor digitorum deepis tendons control the flexion of the distal interphalangeal joints. The principle of finger flexion training is that the patient actively flexes the proximal or distal interphalangeal joint, sliding the corresponding tendon, thereby pulling apart the adhesions and achieving the goal of rehabilitation. However, in practice, due to weeks of immobilization, patients often cannot flex a single joint and instead compensate by flexing other joints. For example, if flexion of the proximal interphalangeal joint is needed to slide the superficial flexor digitorum superficialis tendon, patients often compensate by flexing the metacarpophalangeal joint, which prevents the adhered tendons from being effectively stretched.

[0004] In related techniques, therapists usually need to exert a lot of effort to fix the patient's fingers with their hands. This solves the above problems to some extent, but because the fingers are small, it is difficult to achieve precise fixation by "fixing the hand with the hand". After treating multiple patients in a row, it is easy to cause muscle fatigue in the therapist's hands, which affects the fixation effect, weakens the overall therapeutic effect, and may increase the risk of therapists developing hand-related occupational diseases in the long run. Utility Model Content

[0005] In order to at least overcome some of the defects in the related technologies, this application provides a rehabilitation aid for finger flexor tendons.

[0006] To achieve the above objectives, a finger flexor tendon rehabilitation aid includes a base and a finger sleeve assembly. The base has a sliding groove. The finger sleeve assembly includes a slider and a strap, the slider being slidably mounted within the sliding groove; two spaced-apart limiting members are provided on the side of the slider away from the sliding groove. The strap passes sequentially through the two limiting members, forming a cavity between the two limiting members, allowing the strap and the limiting members to be relatively fixed.

[0007] Furthermore, multiple sliding members are provided in the slide groove, and the length of the sliding member is the same as the width of the belt body along the sliding direction of the sliding member.

[0008] Furthermore, the limiting member is disposed at the edge of the sliding member, and the limiting member has a through hole, through which the belt passes.

[0009] Furthermore, the through hole is interference-fitted with the belt body.

[0010] Furthermore, the length of the belt extending in a direction perpendicular to the groove is L1, and the width of the groove is L2, satisfying: L1 > L2.

[0011] Furthermore, the seat body is provided with a first adhesive portion, which is located on both sides of the slide groove. The belt body has a second adhesive portion on the side facing the first adhesive portion, and the first adhesive portion can be fixed relative to the second adhesive portion.

[0012] Furthermore, the first adhesive part extends along the direction of the groove by a distance of L3, and the length of the slider is L4, satisfying: L3 > L4.

[0013] Furthermore, one end of the groove extends to the end of the seat body, and an opening is formed at the end of the seat body; the first adhesive part is disposed on the seat body at a position away from the opening.

[0014] Furthermore, multiple slides are provided on the base body, and the multiple slides are arranged in parallel.

[0015] Furthermore, the slide groove has an opening at one end of the base and extends away from the opening. The openings of adjacent slide grooves are respectively located at different ends of the base.

[0016] With the above technical solution, when using the finger flexor tendon rehabilitation aid of this application, the sliding member in the finger sleeve assembly is moved to a suitable position along the groove on the base. Then, the strap is adjusted to ensure the cavity formed between the two limiting members is of appropriate size, and the strap is fixed relative to the limiting members. After fixation, the patient inserts their finger into the cavity, and, restricted by the strap, performs finger flexor tendon rehabilitation movements. The size of the cavity and the finger insertion position can be adaptively adjusted according to different fingers and variations in the superficial and deep flexor tendons.

[0017] The finger flexor tendon rehabilitation aid described in this application allows for targeted training of different positions on different fingers during use. The device reliably and precisely fixes and restricts the fingers during training. It eliminates the need for therapists to assist patients, reducing the therapist's workload and lowering their risk of developing hand-related occupational diseases.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] This embodiment provides a finger flexor tendon rehabilitation aid to address the problems in related technologies, such as the difficulty for therapists to maintain precise fixation of the patient's hand for extended periods and the high workload of therapists.

[0029] Please see Figure 1 , Figure 2 A rehabilitation aid for finger flexor tendons includes a base 100 and a finger sleeve assembly 200. The base 100 has a groove 110. The finger sleeve assembly 200 includes a slider 210 and a strap 230. The slider 210 is slidably mounted within the groove 110. Two spaced-apart limiting members 220 are provided on the side of the slider 210 away from the groove 110. The strap 230 passes sequentially through the two limiting members 220, forming a cavity 240 between the two limiting members 220, allowing the strap 230 to be relatively fixed to the limiting members 220.

[0030] When using the finger flexor tendon rehabilitation aid of this embodiment, the therapist or patient first slides the slider 210 to a suitable position, making the area of ​​the patient's finger to be rehabilitated easier to exercise. Next, the band 230 is passed through the two limiting members 220, and the relative position of the band 230 and the limiting members 220 is adjusted so that the cavity 240 between the two limiting members 220 is of a suitable size, allowing the cavity 240 to fit snugly against the patient's finger after insertion, thus fixing the finger in place. After adjusting to a suitable position, the band 230 and the limiting members 220 are fixed together to prevent changes in the size of the cavity 240 during rehabilitation training. Once fixed, the patient can then perform finger flexor tendon rehabilitation training on the specific area of ​​that finger.

[0031] The finger flexor tendon rehabilitation aid in this embodiment requires only adjustment by the therapist; the therapist no longer needs to fix the fingers, reducing the therapist's workload and risk of developing hand-related occupational diseases. Furthermore, this embodiment allows one therapist to simultaneously assist multiple patients, improving work efficiency. Experienced patients can even adjust the device themselves, performing rehabilitation training in any position without therapist assistance. Moreover, the finger flexor tendon rehabilitation aid in this embodiment provides precise fixation of the patient's fingers, preventing situations where therapists become fatigued after prolonged work and are unable to accurately fix the fingers, thus improving the rehabilitation effect. Additionally, using this embodiment allows therapists to focus their attention on other aspects, such as the patient's hand movements, flexion angles, and strength, further enhancing the rehabilitation effect.

[0032] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, multiple sliders 210 are provided in the slide groove 110. Along the sliding direction of the slider 210, the length of the slider 210 is the same as the width of the belt body 230.

[0033] By setting multiple sliders 210, the length of the sliders 210 can be flexibly adjusted according to the size of different patients' fingers, or the size of different fingers of the same patient, as well as the specific area to be exercised. This is equivalent to adjusting the width of the band 230, allowing the band 230 to fit different fingers. This improves the versatility and applicability of the rehabilitation aid, enabling it to serve the needs of more diverse patients.

[0034] Multiple sliders 210 are provided within the slide groove 110, allowing each slider 210 to be adapted to different fingers of the same patient. This eliminates the need for repeated adjustments to the equipment when the patient is performing rehabilitation training on different fingers, making the process of using this embodiment simple and convenient. The multiple sliders 210 can also be adjusted arbitrarily, allowing two patients to share the same rehabilitation equipment during periods of limited use.

[0035] Since the length of the slider 210 is the same as the width of the band 230, when the band 230 passes through the limiting member 220 and is fixed, it can help distribute the force applied to the fingers more evenly, reduce the risk of excessive local pressure, and help improve the comfort and effectiveness of rehabilitation training.

[0036] In one embodiment, exemplarily, such as Figure 1 , Figure 2As shown, the limiting member 220 is located at the edge of the sliding member 210, and a through hole is provided on the limiting member 220, through which the strap 230 passes. By providing a through hole in the limiting member 220 to fix the strap 230, it is ensured that the strap 230 will not easily slide or shift. This allows the formed cavity 240 to fit the patient's finger more securely, providing more reliable support and fixation, which helps to improve the effectiveness of rehabilitation training. Furthermore, this simplifies the adjustment process of the strap 230. The therapist or patient simply passes the strap 230 through the through hole in the limiting member 220 and adjusts the tightness of the strap 230 as needed. The adjustment process is more intuitive, convenient, and easy to operate; experienced patients can complete the adjustment themselves without much assistance.

[0037] Because the limiting member 220 is located at the edge of the sliding member 210, and the band 230 can be freely adjusted according to the patient's needs and fixed through the through hole, this design can better adapt to fingers of different sizes and shapes, thereby improving the comfort of use. At the same time, it also ensures that the fingers can be exercised in the most suitable position during rehabilitation training. Of course, in specific use, this embodiment can also, according to actual conditions, provide a suitably shaped metal piece on the band 230 between the two limiting members 220 to further ensure the shape of the cavity 240 so that it fits the finger more closely.

[0038] In one embodiment, for example, the through-hole and the strap 230 are interference-fitted. This interference fit effectively prevents unnecessary slippage or loosening of the strap 230 during use. That is, after the strap 230 is adjusted to the appropriate tightness and passes through the through-hole of the retainer 220, it can be securely held in that position, ensuring stable support and fixation of the finger throughout the rehabilitation training process. The interference fit also allows for more precise adjustment of the strap 230's position, and once adjusted, it can be well maintained. Therapists or patients do not need to frequently adjust the tightness of the strap 230, thus allowing them to focus on the rehabilitation training itself.

[0039] Since the belt 230 does not move easily, this reduces the potential risks caused by the belt 230 sliding, such as a finger accidentally slipping out of the cavity 240 or secondary injury caused by insecure fixation, thus improving the safety of this embodiment.

[0040] In one embodiment, exemplarily, such as Figure 2As shown, the length of the belt body 230 extending perpendicularly to the slide groove 110 is L1, and the width of the slide groove 110 is L2, satisfying L1 > L2. The length of the belt body 230 extending perpendicularly to the slide groove 110 is greater than the width of the slide groove 110, meaning that the arrangement of the belt body 230 on the slider 210 has a certain margin, allowing the belt body 230 to be adjusted within a wider range on the slider 210 when needed, thereby adapting to different finger sizes or rehabilitation training needs.

[0041] The groove 110 has a smaller width, while the belt body 230 extends a larger length. This reduces the constraint of the sliding member 210 on the belt body 230, allowing the belt body 230 to adjust its angle and tension more freely after passing through the limiting member 220.

[0042] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, the seat 100 is provided with a first adhesive part 120, which is located on both sides of the slide groove 110. The belt 230 has a second adhesive part on the side facing the first adhesive part 120, and the first adhesive part 120 can be fixed relative to the second adhesive part. The adhesive parts ensure that the belt 230 will not easily move or slide after being adjusted to a suitable position, providing a more stable and reliable fixed environment for rehabilitation training and helping to improve the effectiveness of rehabilitation training.

[0043] Using adhesive parts for fixation simplifies the adjustment process. Once the belt 230 passes through the limiting member 220 and is adjusted to the appropriate tightness, simply align the second adhesive part with the first adhesive part 120 to complete the fixation. No additional tools or complicated procedures are required, improving ease of use. If the adhesive position is not suitable or needs adjustment, simply separate the second adhesive part from the first adhesive part 120 and then re-adhere it.

[0044] It is understood that in this embodiment, the first adhesive part 120 and the second adhesive part can be selected from any adhesive material according to actual needs. For example, both the first adhesive part 120 and the second adhesive part can be set as Velcro, which can achieve the fixing requirements of this embodiment. Selecting appropriate adhesive materials can ensure that the device is not easily damaged during long-term use and is easy to clean and maintain. This not only extends the service life of the device but also reduces the cost of long-term use.

[0045] Please continue reading. Figure 1 , Figure 2For example, the first adhesive portion 120 extends along the direction of the slide groove 110 by a distance L3, and the length of the slider 210 is L4, satisfying L3 > L4. The distance the first adhesive portion 120 extends along the direction of the slide groove 110 is greater than the length of the slider 210. The first adhesive portion 120 covers the entire range of motion of the slider 210, with additional space. This allows the band 230 to be fixed at any position of the slider 210 without failure due to insufficient adhesive portion. In other words, the patient can slide the slider 210 to any comfortable position for rehabilitation training, improving the practicality of this embodiment.

[0046] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, one end of the slide 110 extends to the end of the base 100, and an opening is formed at the end of the base 100; the first adhesive part 120 is disposed on the base 100 away from the opening. The opening design allows the slider 210 to be more easily inserted into or removed from one end of the base 100. When it is necessary to replace or adjust the slider 210, the operation is more convenient, without disassembling the entire device, saving time and simplifying the maintenance process. The slide 110 extends to the end of the base 100 and has an opening there, so that the slider 210 can move freely along the entire length of the slide 110, including reaching the very end. This increases the possibility of adjusting the position of the slider 210, thereby better adapting to the finger size and rehabilitation needs of different patients.

[0047] The first adhesive part 120 is located on the seat 100 away from the opening, ensuring that even if the slider 210 is located at the very end of the slide groove 110, it can still find a suitable place for fixation. Since patients usually place their palms on the end of the seat 100 away from the opening when using this embodiment, this layout avoids the problem of inconvenience in fixation caused by structural limitations near the opening, and also makes this embodiment more suitable for patients' usage habits, improving the convenience of use.

[0048] Furthermore, this design also reduces the risk of accidental detachment of the slider 210. The opening facilitates the installation and removal of the slider 210, but by placing it at one end and properly arranging the first adhesive part 120, it can be ensured that the slider 210 is stable and does not shift during normal use. Even if slight displacement occurs, it will not directly detach from the opening and fall outside the groove 110, thus improving the overall safety of this embodiment.

[0049] In one embodiment, for example, multiple slides 110 are provided on the base 100, and the multiple slides 110 are arranged in parallel. The design of multiple slides 110 allows for the simultaneous installation of multiple sliders 210 and their corresponding finger sleeve assemblies 200. Different finger sleeve assemblies 200 can match multiple fingers on one hand or different parts of the same finger. Thus, during rehabilitation training, there is no need to adjust the finger sleeve assembly 200, improving the convenience of using the device.

[0050] Different patients may have different finger lengths, thicknesses, and specific areas requiring rehabilitation. Multiple slides 110 provide a more flexible platform, allowing the position of each slide 210 to be adjusted according to each patient's specific needs, thereby better meeting personalized rehabilitation requirements.

[0051] For therapists, using rehabilitation aids with multiple grooves 110 allows them to serve multiple patients at the same time or treat multiple finger problems of a patient at once, greatly improving work efficiency.

[0052] In one embodiment, for example, the slide 110 has an opening formed at one end of the seat 100 and extends toward the end away from the opening. The openings of adjacent slides 110 are respectively located at different ends of the seat 100. This design, where the openings of adjacent slides 110 are located at different ends, increases the flexibility of the system. The therapist or patient can choose from which end to install or remove the slider 210 depending on the specific situation, which is particularly useful when dealing with multiple fingers or fingers in different positions, improving the ease and flexibility of operation.

[0053] The staggered openings allow the positions of the sliders 210 to be staggered as well, leaving more space for the patient's palm and making the structure of this embodiment more reasonable.

[0054] In one embodiment, exemplarily, such as Figure 3 As shown, the strap 230 can also be directly fixed to the base 100. Multiple straps 230 of different lengths and widths can be provided on the base 100 by adjusting the length and width of the strap 230. Different patients have different finger sizes, shapes, and rehabilitation needs. Providing straps 230 of various lengths and widths allows for selection of the most suitable configuration for the patient's fingers, thereby better adapting to individual differences and improving rehabilitation outcomes. Furthermore, this embodiment has a simple structure, low cost, and is easy to manufacture.

[0055] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
