Description

Technical Field

[0001] The utility model belongs to the technical field of medical protective gear, and in particular relates to an auxiliary ankle positioner. Background Art

[0002] The ankle joint is composed of the articular surface of the lower end of the tibia and fibula and the talar pulley. Fractures or sprains are prone to occur at the ankle joint. Postoperative auxiliary treatment of ankle fractures or sprains requires auxiliary positioners or plaster. Because auxiliary positioners are lighter and more convenient, they are accepted by the majority of patients.

[0003] At each stage of ankle injury rehabilitation, the strength of tissue repair is different, and the stability of the ankle joint is different, so a more flexible external fixation support is needed to assist with stability. However, the existing positioners do not have the option of adjusting the support strength (either full support brace or non-support soft brace), and cannot cover the complete post-injury (or post-surgery) rehabilitation cycle. Utility Model Content

[0004] The utility model provides an auxiliary ankle positioner to solve at least one of the above technical problems.

[0005] The technical solution adopted by the utility model is:

[0006] An ankle auxiliary locator comprises a foot cover, wherein both sides of the foot cover are detachably connected with a clamping part for clamping the ankle joint, the outer side of the clamping part is detachably connected with a reinforcing part for increasing the supporting strength of the clamping part, and the outer side of the foot cover is provided with an adjusting part for adjusting the pressure between the clamping part and the outer side of the ankle joint.

[0007] Preferably, the clamping portion comprises two first guard plates, which are detachably connected to two sides of the foot cover and whose positions match the ankle joint.

[0008] Preferably, the reinforcement portion includes two second guard plates which are detachably connected to the outer sides of the two first guard plates respectively.

[0009] Preferably, the outer surfaces of the foot cover on both sides of the ankle joint are provided with Velcro fleece surfaces, and the first guard plate is provided with Velcro thorn surfaces matching with the Velcro fleece surfaces.

[0010] Preferably, a connecting groove is provided on the side of the first guard plate away from the Velcro thorn surface, and a connecting flange that slidably cooperates with the connecting groove is provided on the side of the second guard plate adjacent to the first guard plate.

[0011] Preferably, a plurality of bosses are provided on a side of the first guard plate away from the Velcro thorn surface, and a plurality of slots cooperating with the bosses are provided on the second guard plate.

[0012] Preferably, the structural strength of the first guard plate is smaller than that of the second guard plate, the first guard plate is made of soft plastic material, and the second guard plate is made of hard plastic material or metal material.

[0013] Preferably, the adjustment part includes a first elastic strap and a second elastic strap, and the positions of the first elastic strap and the second elastic strap respectively correspond to the upper and lower ends of the first guard plate or the second guard plate, and the two ends of the first elastic strap are fixed by pasting through a first Velcro assembly, and the two ends of the second elastic strap are fixed by pasting through a second Velcro assembly.

[0014] Preferably, it also includes a wrapping strap, both ends of which are fixed by sticking via a third Velcro assembly, and the wrapping strap is wrapped in an "8" shape to form a protective structure that simultaneously protects the ankle joint, the instep, and the sole of the foot.

[0015] Preferably, the foot cover comprises a foot wrapping cover, and two ends of the foot wrapping cover are respectively provided with a toe hole for toes to pass through and a heel hole for heels to pass through.

[0016] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0017] 1. In this application, the foot cover is designed to be a tube sock structure that fits the patient's calf and foot, so that the patient can wear it easily. The foot cover can provide basic protection for the injured ankle. After the foot cover is worn, the fit between the foot cover and the patient's calf and / or ankle joint and / or sole is adjusted by the adjustment part to increase the protective effect of the foot cover on the patient's injured ankle joint. When the patient's ankle is moderately sprained, the setting of the clamping part can provide soft support for the injured ankle, and the pressure of the two clamping parts on both sides of the patient's ankle joint is adjusted by the adjustment part to increase the protective effect of the clamping part on both sides of the patient's injured ankle joint. When the patient's ankle is severely sprained, reinforcement parts are installed on the outer sides of the two clamping parts to increase the structural strength of the clamping parts, so that the clamping parts can be upgraded from the original soft support to the rigid support, which plays a significant role in positioning and limiting the injured ankle, thereby ensuring the rapid recovery of the ankle. Similarly, the adjustment part adjusts the pressure of the two clamping parts and the reinforcement parts on both sides of the patient's ankle joint as a whole, thereby increasing the positioning and limiting protection effect of the clamping parts and the reinforcement parts on both sides of the patient's injured ankle joint.

[0018] In addition, patients with severe ankle sprains will experience early rehabilitation (including acute and subacute phases), mid-rehabilitation, and late rehabilitation phases in their ankle recovery period. In the early rehabilitation phase, especially the acute phase, the ankle joint is poorly stable and requires strong external support to ensure stability in order to facilitate tissue healing. The patient can position and limit the patient's ankle joint through the joint action of the foot cover, clamping part, reinforcement part, and adjustment part. At this time, the wearing time covers the middle and late stages of the subacute phase; from the end of the subacute phase to the mid-term of complete rehabilitation, the strength of the healing scar of the ankle soft tissue structure gradually increases, and the affected ankle can gradually transition to partial support. At this time, the patient can remove the reinforcement part and position and limit the patient's ankle joint through the joint action of the foot cover, clamping part, and adjustment part. When entering the late rehabilitation phase, the structural stability of the ankle has been significantly improved, but the ankle still needs ankle protection for long-term walking or exercise. The patient can remove the lateral elastic support protection and use elastic fabric to assist the soft tissue of the ankle joint to ensure the stability of the ankle joint. In other words, this application can cover the entire rehabilitation period of patients with severe sprains, and patients can flexibly adjust according to their own injuries, greatly increasing the practicality of this locator.

[0019] 2. As a preferred embodiment of the utility model, the two first guard plates can be used to clamp, position and protect the ankles. It should be noted that the shape of the first guard plate is the same or similar to the convex structure outside the ankle joint, thereby achieving excellent correction, fixation and protection effects, and facilitating the positioning of the first guard plate. When the first guard plate is installed, the curved surface of the first guard plate is closely fitted with the convex structure outside the ankle joint and the installation position of the first guard plate in the manual is accurate. On the other hand, the foot cover is made of soft and skin-friendly textile material, and the first guard plate is a harder plate. The first guard plate is removed from the foot cover, which is conducive to cleaning the foot cover.

[0020] 3. As a preferred embodiment of the utility model, the second guard plate is connected to the first guard plate to form a whole, thereby changing the structural strength of the first guard plate. The overall structure after the first guard plate and the second guard plate are coordinated has a higher strength limiting protection effect on the patient's ankle joint.

[0021] 4. As a preferred embodiment of the present invention, the first guard plate and the second guard plate are connected into a whole by sliding fit between the connecting flange and the connecting groove. The operation is simple and efficient. Moreover, since the contact area between the connecting groove and the connecting flange is large, the friction force between the two is sufficient to ensure that there will be no relative displacement between the first guard plate and the second guard plate without applying external force.

[0022] On the other hand, the setting of the connecting flange can increase the structural strength of the second guard plate, further enhancing the limiting protection effect on the patient's ankle joint, while also helping to increase the service life of the second guard plate.

[0023] 5. As a preferred embodiment of the present invention, the interference fit between the boss and the slot can effectively prevent the first guard plate from detaching from the second guard plate. At least two bosses and two slots are provided to ensure that the second guard plate will not be offset. The height of the boss is the same as the depth of the slot. After the second guard plate is installed and matched with the first guard plate, no convex or concave structure will appear on the end surface of the first guard plate that fits the foot cover, thereby reducing the discomfort caused by the first guard plate squeezing the ankle joint.

[0024] 6. As a preferred embodiment of the present invention, the Velcro fleece surface and the Velcro thorn surface are quickly pasted and fixed to the foot cover, which is easy to operate and greatly enhances the user experience.

[0025] 7. As a preferred embodiment of the present invention, the upper and lower ends of the first guard plate and the second guard plate can be tightened and fixed respectively by the arrangement of the first elastic strap and the second elastic strap to prevent the first guard plate and the second guard plate from shifting due to the patient's activities. At the same time, the tightness of the first elastic strap and the second elastic strap can be adjusted by adjusting the overlapping area of ​​the first Velcro assembly and the second Velcro assembly. The patient can adjust them by himself as needed, thereby improving the patient's comfort during wearing and increasing the patient's usage experience.

[0026] 8. As a preferred embodiment of the present invention, the provision of a wrapping strap can further increase the fit between the foot cover and the patient's calf and sole, while further increasing the protective effect on the ankle joint and sole, thereby preventing the patient from secondary sprain.

[0027] 9. As a preferred embodiment of the present invention, the provision of toe holes and heel holes can further increase the degree of fit between the foot cover and the sole of the foot, making the foot cover fit the patient better and more comfortable to wear.

[0044] Reference Figure 1-Figure 4 An ankle auxiliary positioner comprises a foot cover 1, both sides of the foot cover 1 are detachably connected with a clamping part for clamping the ankle joint, the outer side of the clamping part is detachably connected with a reinforcing part for increasing the supporting strength of the clamping part, and the outer side of the foot cover 1 is provided with an adjusting part for adjusting the pressure between the clamping part and the outer side of the ankle joint.

[0045] It is understood by those skilled in the art that during the recovery period of a sprained ankle, patients need auxiliary protection and bone setting to prevent the ankle joint from being injured again and dislocation of the ankle joint due to stress. When the patient's ankle is slightly sprained, the medical staff guides the patient to wear the foot cover 1 to the injured part. The foot cover 1 is designed to fit the structure of a tube sock on the patient's calf and foot, so that the patient can wear it easily. The foot cover 1 can play a basic protective role for the injured ankle. After the foot cover 1 is put on, the fit between the foot cover 1 and the patient's calf and / or ankle joint and / or sole is adjusted by the adjustment part to increase the protective effect of the foot cover 1 on the patient's injured ankle joint. When the patient's ankle is moderately sprained, after the patient puts on the foot cover 1, the clamping parts are installed on both sides of the foot cover 1. The two clamping parts are respectively located on the inner and outer sides of the injured ankle joint. The two clamping parts clamp the ankle joint from the inner and outer sides of the injured ankle joint to assist in fixing and limiting. The setting of the clamping parts can play a role of soft support for the injured ankle. The pressure of the two clamping parts on both sides of the patient's ankle joint is adjusted by the adjustment part to increase the protective effect of the clamping parts on both sides of the patient's injured ankle joint. When the patient's ankle is severely sprained, the reinforcement parts are installed on the outer sides of the two clamping parts to increase the structural strength of the clamping parts, so that the clamping parts can be upgraded from the original soft support to the rigid support, which plays a significant role in positioning and limiting the injured ankle, thereby ensuring the rapid recovery of the ankle. Similarly, the pressure of the two clamping parts and the reinforcement parts on both sides of the patient's ankle joint is adjusted by the adjustment part to increase the positioning and limiting protection effect of the clamping parts and the reinforcement parts on both sides of the patient's injured ankle joint.

[0046] In addition, patients with severe ankle sprains will experience the early rehabilitation period (including acute and subacute periods), mid-rehabilitation period, and late rehabilitation period in their ankle recovery period. In the early rehabilitation period, especially the acute period, the ankle joint stability of the patient is poor, and strong external support is needed to ensure the stability of the period to facilitate tissue healing. The patient can use the foot cover 1, the clamping part, the reinforcement part and the adjustment part to position and limit the patient's ankle joint. At this time, the wearing time covers the middle and late stages of the subacute period; from the end of the subacute period to the middle stage of complete rehabilitation, the strength of the healing scar of the ankle soft tissue structure gradually increases, and the affected ankle can gradually transition to partial support. At this time, the patient can remove the reinforcement part and use the foot cover 1, the clamping part and the adjustment part to position and limit the patient's ankle joint. When entering the late rehabilitation period, the structural stability of the ankle has been significantly improved, but the ankle still needs to be protected by an ankle guard when walking or exercising for a long time. The patient can remove the lateral elastic support protection and use elastic fabric to assist the soft tissue of the ankle joint to ensure the stability of the ankle joint. In other words, this application can cover the entire rehabilitation period of patients with severe sprains, and patients can flexibly adjust according to their own injuries, greatly increasing the practicality of this locator.

[0047] As a preferred embodiment of the present application, two silicone pads are provided in the foot cover 1 to match the ankle joints, so as to reduce the discomfort caused by the clamping part pressing on the ankle joints.

[0048] As a specific embodiment of the clamping portion in this application, refer to Figure 1 , Figure 2 The clamping part includes two first guard plates 2, which are detachably connected to both sides of the foot cover 1 and whose positions match the ankle joint.

[0049] The two first guard plates 2 can be used to clamp, position and protect both sides of the ankle. It should be noted that the shape of the first guard plate 2 is the same or similar to the convex structure outside the ankle joint, thereby achieving excellent correction, fixation and protection effects, and facilitating the positioning of the first guard plate 2. When the first guard plate 2 is installed, the curved surface of the first guard plate 2 is closely fitted with the convex structure outside the ankle joint and the installation position of the first guard plate 2 is accurate. On the other hand, the foot cover 1 is made of soft and skin-friendly textile material, and the first guard plate 2 is a harder plate. The first guard plate 2 is removed from the foot cover 1, which is conducive to cleaning the foot cover 1.

[0050] As a specific implementation of the reinforcement part in this application, refer to Figure 1-Figure 2 The reinforcement part includes two second guard plates 3 which are detachably connected to the outer sides of the two first guard plates 2 respectively. The second guard plates 3 are connected to the first guard plates 2 to form a whole, thereby changing the structural strength of the first guard plates 2. The overall structure after the first guard plates 2 and the second guard plates 3 are coordinated has a higher strength limiting protection effect on the patient's ankle joint.

[0051] It should be noted that the structural strength of the first guard plate 2 is less than that of the second guard plate 3. The first guard plate 2 is made of soft plastic material, such as polyethylene material with a thickness of 2-5 mm, and the second guard plate 3 is made of hard plastic material, such as epoxy resin with a thickness of 2-5 mm, or metal material, such as aluminum alloy material with a thickness of 2-5 mm. Both the first guard plate 2 and the second guard plate 3 meet medical standards and are preferably non-toxic, harmless and recyclable environmentally friendly materials.

[0052] The present application does not specifically limit the detachable connection method between the second guard plate 3 and the first guard plate 2, and any one of the following embodiments may be adopted:

[0053] Example 1: Reference Figure 5-Figure 6 A connecting groove 202 is provided on the side of the first guard plate 2 away from the Velcro thorn surface 201 , and a connecting flange 301 that slidably cooperates with the connecting groove 202 is provided on the side of the second guard plate 3 adjacent to the first guard plate 2 .

[0054] The connecting flange 301 and the connecting groove 202 are slidably matched to connect the first guard plate 2 and the second guard plate 3 into a whole, which is simple and efficient to operate. Moreover, since the contact area between the connecting groove 202 and the connecting flange 301 is large, the friction force between the two is sufficient to ensure that no relative displacement occurs between the first guard plate 2 and the second guard plate 3 without applying external force.

[0055] On the other hand, the setting of the connecting flange 301 can increase the structural strength of the second guard plate 3, further enhancing the limiting protection effect on the patient's ankle joint, while also being beneficial to increasing the service life of the second guard plate 3.

[0056] Example 2: Reference Figure 7-Figure 8 A plurality of bosses 203 are provided on the side of the first guard plate 2 away from the Velcro thorn surface 201 , and a plurality of slots 302 cooperating with the bosses 203 are provided on the second guard plate 3 .

[0057] The interference fit between the boss 203 and the slot 302 can effectively prevent the first guard plate 2 from detaching from the second guard plate 3. At least two bosses 203 and slots 302 are provided to ensure that the second guard plate 3 will not be offset. The height of the boss 203 is the same as the depth of the slot 302. After the second guard plate 3 is installed and matched with the first guard plate 2, there will be no convex or concave structure on the end surface of the first guard plate 2 that fits the foot cover 1, thereby reducing the discomfort caused by the first guard plate 2 squeezing the ankle joint.

[0058] As a preferred example of a detachable connection between the first guard plate 2 and the foot cover 1, refer to Figure 3 and Figure 4 The outer surfaces of the foot cover 1 on both sides of the ankle joint are provided with Velcro fleece surfaces 101 , and the first guard plate 2 is provided with Velcro thorn surfaces 201 that cooperate with the Velcro fleece surfaces 101 .

[0059] The arrangement of the Velcro fleece surface 101 and the Velcro thorn surface 201 allows the first guard plate 2 to be quickly adhered and fixed to the foot cover 1 , which is easy to operate and greatly enhances the user experience.

[0060] As a specific implementation of the adjustment unit in this application, refer to Figure 1-Figure 2 The adjustment part includes a first elastic strap 4 and a second elastic strap 5. The positions of the first elastic strap 4 and the second elastic strap 5 correspond to the upper and lower ends of the first guard plate 2 or the second guard plate 3 respectively. The two ends of the first elastic strap 4 are fixed by pasting through the first Velcro component 401, and the two ends of the second elastic strap 5 are fixed by pasting through the second Velcro component 501.

[0061] By setting the first elastic strap 4 and the second elastic strap 5, the upper and lower ends of the first guard plate 2 and the second guard plate 3 can be tightened and fixed respectively to prevent the first guard plate 2 and the second guard plate 3 from shifting due to patient activities. At the same time, the tightness of the first elastic strap 4 and the second elastic strap 5 can be adjusted by adjusting the overlapping area of ​​the first Velcro component 401 and the second Velcro component 501. The patient can adjust it by himself as needed, thereby improving the patient's comfort during wearing and enhancing the patient's usage experience.

[0062] As a preferred embodiment of the present application, refer to Figure 1-Figure 3 It also includes a wrapping strap 6, both ends of which are fixed by sticking via a third Velcro assembly 601, and the wrapping strap 6 is wrapped in an "8" shape to form a protective structure that simultaneously protects the ankle joint, the instep, and the sole of the foot.

[0063] By setting the wrapping strap 6, the fit between the foot cover 1 and the patient's calf and sole can be further increased, and at the same time, the protection effect on the ankle joint and sole can be further increased to avoid secondary sprain of the patient.

[0064] Furthermore, the foot cover 1 has a foot wrapping cover, and both ends of the foot wrapping cover are respectively provided with a toe hole 102 for the toes to pass through and a heel hole 103 for the heels to pass through. The setting of the toe hole 102 and the heel hole 103 can further increase the fit between the foot cover 1 and the sole of the foot, making the foot cover 1 more fit to the patient and more comfortable to wear.

[0065] In addition, as a preferred example of the present application, the foot cover 1, the first elastic strap 4, the second elastic strap 5 and the wrapping strap 6 are all made of breathable and elastic knitted fabrics, which increase the comfort of the patient during the wearing process and improve the patient's usage experience.
