Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation training, and particularly relates to an insole for the rehabilitation period after ankle surgery. Background Art

[0002] Rehabilitation training refers to physical activities that are beneficial to the recovery or improvement of functions after an injury. Except for severe injuries that require rest and treatment, general injuries do not necessarily require complete cessation of physical exercises. Appropriate and scientific physical exercises play a positive role in the rapid healing of injuries and the promotion of functional recovery.

[0003] In the prior art, after ankle surgery, the common fixation methods are plaster fixation and brace fixation. Plaster fixation can effectively fix the ankle joint, but during the mid - stage of ankle rehabilitation, the plaster needs to be removed, which cannot help with the mid - stage rehabilitation of the ankle joint. Although brace fixation can allow the ankle joint to move to a certain extent, conventional braces can only limit and adjust the angles of ankle plantar flexion - dorsiflexion and inversion - eversion exercises, and cannot adjust the circumferential limiting angle of the ankle joint according to the rehabilitation situation of the ankle joint, making it difficult to adapt to different exercises for ankle rehabilitation (such as ankle plantar flexion and dorsiflexion exercises, ankle inversion - eversion exercises, ankle circumduction exercises, etc.). Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an insole for the rehabilitation period after ankle surgery to solve the problems that the prior art is not convenient for adjustment according to the patient's rehabilitation situation and is difficult to meet the different exercise requirements for ankle rehabilitation.

[0005] To solve the above - mentioned technical problem, the present invention provides the following technical solutions:

[0006] An insole for the rehabilitation period after ankle surgery, comprising an insole, one side of the insole is fixedly connected with an elastic band, and the heel of one side of the insole is fixedly connected with a sleeve bag; an adjustment component for adjusting the size of the insole, the adjustment component is connected with the insole; a rehabilitation component for assisting the patient's ankle rehabilitation, the rehabilitation component is connected with the insole, the elastic band and the sleeve bag.

[0007] Optionally, the adjustment component includes a first insole sleeve, a second insole sleeve and a third insole sleeve, and the outer wall of the insole is sequentially sleeved with the first insole sleeve, the second insole sleeve and the third insole sleeve from the inside out.

[0008] Optionally, the inner cavity of the first insole sleeve is adapted to the outer wall of the insole, the inner cavity of the second insole sleeve is adapted to the outer wall of the first insole sleeve, and the inner cavity of the third insole sleeve is adapted to the outer wall of the second insole sleeve.

[0009] Optionally, the rehabilitation component includes a connecting piece disposed on one side of the insole. The connecting piece is inserted inside the elastic band and the sleeve bag. A first magic tape is fixedly connected inside the connecting piece, and an L-shaped support piece is slidably connected inside the connecting piece.

[0010] Optionally, a connecting block is slidably connected to one end of the L-shaped support piece away from the connecting piece. An elastic soft band is fixedly connected to one side of the connecting block, and the end of the elastic soft band away from the connecting block is fixedly connected to the bent portion of the L-shaped support piece.

[0011] Optionally, a tapered groove is formed at the top of the connecting block. The semi-circular block is inserted inside the tapered groove. A limiting member is fixedly connected to the top of the connecting block. A rotating member is rotatably connected inside the limiting member. A bolt is threadedly connected inside the rotating member. One end of the bolt close to the connecting block is fixedly connected with a semi-circular block.

[0012] Optionally, a tapered groove is formed at the top of the connecting block. The semi-circular block is inserted inside the tapered groove. A U-shaped limiting rod is inserted into the outer wall of the connecting block. A first slot and a second slot are formed inside the connecting block.

[0013] Optionally, a clamping block is slidably connected inside the connecting block. A clamping slot adapted to the clamping block is formed inside the L-shaped support piece. One end of the clamping block away from the clamping slot is inserted into the first slot.

[0014] Optionally, one end of the rotating member is fixedly connected with a binding piece. A weakening groove is formed on one side of the binding piece away from the rotating member. The number of the binding pieces is set to be multiple. Third slots are symmetrically formed inside multiple binding pieces.

[0015] Optionally, a connecting band is inserted into the third slot. The connecting band passes through the third slots of multiple binding pieces in a "bow" shape in sequence. A second magic tape is fixedly connected to one end of the connecting band away from the rotating member. An insertion ring is fixedly connected to one end of the connecting band close to the rotating member.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, by setting up the rehabilitation component, the positions of the bolt and the semi-circular block inside the conical groove can be adjusted, changing the limitation on the circumferential movement range of the patient's ankle joint. This allows the patient to adjust the positions of the bolt and the semi-circular block inside the conical groove according to the progress of ankle joint rehabilitation exercises, avoiding the situation where the movement range of the ankle joint exceeds the limit during rehabilitation exercises, resulting in unrelieved swelling and pain in the ankle joint the next day, which affects the rehabilitation of the ankle joint. After the circumferential movement range of the ankle joint increases, the patient can perform circumduction exercises on the ankle joint, exercising the circumferential directions of the ankle joint, improving the freedom degree of the rehabilitation component, and can also adjust the position of the U-shaped limiting rod to limit plantar flexion, dorsiflexion, and inversion / eversion exercises, avoiding deviation in the exercise angle and forming incorrect ankle joint movement angles, which affect the gait after rehabilitation and the rehabilitation effect.

[0018] By setting up the adjustment component, when the patient needs to adjust the size of the insole to make the insole fit the shoe and the foot, the patient can change the number of insole covers sleeved on the outer wall of the insole until the sizes of the insole and the insole covers fit the patient's shoe and foot, improving the applicable range of the insole, thereby adapting to different patients' feet and shoes of different sizes. At the same time, when the patient's ankle joint rehabilitation is completed, the insole covers sleeved on the insole can be removed, and the insole can be cleaned, disinfected, and reused, reducing costs and wasting resources.

[0034] As Figures 1 to 6 shown, an embodiment of the present invention provides an insole for the rehabilitation period after ankle surgery, including an insole 1, a stretchable band 2 fixedly connected to one side of the insole 1, and a sleeve 3 fixedly connected to the heel on one side of the insole 1; an adjustment component for adjusting the size of the insole 1, the adjustment component being connected to the insole 1, and by providing the adjustment component, the number of insole covers sleeved on the insole 1 can be changed, so as to adapt to the feet and shoes of different sizes of different patients; a rehabilitation component for assisting the patient's ankle rehabilitation, the rehabilitation component being connected to the insole 1, the stretchable band 2, and the sleeve 3.

[0035] By providing the rehabilitation component, the positions of the adjusting bolt 14 and the semi-circular block 15 inside the conical groove 16 can be adjusted, changing the limitation on the circumferential movement range of the patient's ankle, enabling the patient to adjust the positions of the adjusting bolt 14 and the semi-circular block 15 inside the conical groove 16 according to the progress of ankle rehabilitation exercises, avoiding that when the ankle undergoes rehabilitation exercises, the movement range of the ankle exceeds the limit, resulting in unrelieved swelling and pain at the ankle the next day, which affects the rehabilitation of the ankle; the position of the U-shaped limiting rod 17 can be adjusted to limit plantar flexion, dorsiflexion, and inversion / eversion exercises, avoiding deviation of the exercise angles, forming incorrect ankle movement angles, which affects the gait during walking after rehabilitation. At the same time, since the insole for the rehabilitation period after ankle surgery is used in cooperation with shoes, when the patient performs walking rehabilitation exercises, the heights of both feet are the same, which can better restore the patient's walking gait, thus avoiding the situation where the existing rehabilitation device has a different height from the shoes, and when the patient performs walking rehabilitation exercises, the heights of both feet are different, resulting in problems with the patient's walking rehabilitation exercise gait.

[0036] As Figures 2 to 3As shown in the figure, the adjustment component includes a first insole sleeve 4, a second insole sleeve 5, and a third insole sleeve 6. The outer wall of the insole 1 is sequentially sleeved with the first insole sleeve 4, the second insole sleeve 5, and the third insole sleeve 6 from the inside out. The inner cavity of the first insole sleeve 4 is adapted to the outer wall of the insole 1, the inner cavity of the second insole sleeve 5 is adapted to the outer wall of the first insole sleeve 4, and the inner cavity of the third insole sleeve 6 is adapted to the outer wall of the second insole sleeve 5. When the patient needs to adjust the size of the insole 1 to make the insole 1 fit the shoe and the foot, the patient can change the number of insole sleeves sleeved on the outer wall of the insole 1 until the sizes of the insole 1 and the insole sleeves fit the patient's shoe and foot, thereby improving the applicable range of the insole 1 and adapting to the feet and shoes of different patients. At the same time, when the patient's ankle joint rehabilitation is completed, the insole sleeves sleeved on the insole 1 can be removed, and the insole 1 can be cleaned, disinfected, and reused, reducing costs and waste of resources.

[0037] As Figures 3 to 6 shown in the figure, the rehabilitation component includes a connecting piece 7 arranged on one side of the insole 1. The connecting piece 7 is inserted into the inside of the elastic band 2 and the sleeve bag 3. A first magic tape 8 is fixedly connected inside the connecting piece 7. An L-shaped support piece 9 is slidably connected inside the connecting piece 7. One end of the L-shaped support piece 9 away from the connecting piece 7 is slidably connected with a connecting block 10. Through the sliding connection of the L-shaped support piece 9 and the connecting block 10, the L-shaped support piece 9 and the connecting block 10 can compensate for the errors generated when the ankle joint rotates and the rotating part 13 rotates inside the limiting part 12, preventing the rehabilitation component from being stuck and affecting the auxiliary effect of the ankle joint rehabilitation exercise.

[0038] One side of the connecting block 10 is fixedly connected with an elastic soft band 11. One end of the elastic soft band 11 away from the connecting block 10 is fixedly connected to the bent part of the L-shaped support piece 9. The top of the connecting block 10 is fixedly connected with a limiting part 12. A rotating part 13 is rotatably connected inside the limiting part 12. One end of the rotating part 13 is fixedly connected with a binding piece 22. A weakening groove is formed on the side of the binding piece 22 away from the rotating part 13. By forming the weakening groove on the binding piece 22, the binding piece 22 can be deformed to adapt to the arcs of the calves of different patients.

[0039] The number of the binding pieces 22 is set to be multiple. Third slots 23 are symmetrically formed inside the multiple binding pieces 22. A connecting belt 24 is inserted into the inside of the third slots 23. The connecting belt 24 passes through the third slots 23 of the multiple binding pieces 22 in a "bow" shape in sequence. One end of the connecting belt 24 away from the rotating member 13 is fixedly connected with a second magic tape 25. One end of the connecting belt 24 close to the rotating member 13 is fixedly connected with an insertion ring 26. A bolt 14 is connected to the inside of the rotating member 13 by a thread. One end of the bolt 14 close to the connecting block 10 is fixedly connected with a semi-circular block 15. A conical groove 16 is formed at the top of the connecting block 10. The semi-circular block 15 is inserted into the inside of the conical groove 16. A U-shaped limiting rod 17 is inserted into the outer wall of the connecting block 10. A first slot 18 and a second slot 19 are formed inside the connecting block 10. A clamping block 20 is slidably connected to the inside of the connecting block 10. A slot 21 adapted to the clamping block 20 is formed inside the L-shaped support piece 9. One end of the clamping block 20 away from the slot 21 is inserted into the inside of the first slot 18.

[0040] When the insole for the rehabilitation period after ankle joint surgery is fixed to the patient's foot after ankle joint surgery in cooperation with the shoe, when it is necessary to fix the patient's ankle joint, the bolt 14 can be rotated to make the bolt 14 slide along the inside of the rotating member 13 until the semi-circular block 15 at one end of the bolt 14 abuts against the bottom of the conical groove 16 and then stops. At this time, the connecting block 10 and the rotating member 13 are fixedly connected together through the bolt 14, the semi-circular block 15 and the conical groove 16 and cannot rotate. Furthermore, the foot and the calf are fixed and cannot rotate, so as to achieve the effect of fixing the ankle joint. When the ankle joint has not recovered to the stage of rehabilitation exercise, the ankle joint can be limited and fixed to avoid strain caused by the rotation of the ankle joint.

[0041] When ankle joint rehabilitation exercise is needed, the position of the bolt 14 inside the rotating part 13 can be adjusted according to the patient's rehabilitation condition, so that the bolt 14 drives the semi-circular block 15 to adjust its position inside the tapered groove 16. Due to the shape of the tapered groove 16, when the semi-circular block 15 abuts against the bottom of the tapered groove 16, the ankle joint cannot move. As the semi-circular block 15 approaches the rotating part 13, the circumferential movement range of the semi-circular block 15 inside the tapered groove 16 gradually increases, and the circumferential movement range of the ankle joint also gradually increases. When the patient is performing ankle joint exercise, the connecting block 10 fixed on the foot will rotate with the foot according to the ankle joint rehabilitation exercise, so that the tapered groove 16 on the connecting block 10 will rotate relative to the semi-circular block 15 until it is stopped by being limited after the tapered groove 16 abuts against the semi-circular block 15, so that the patient's ankle joint is limited after rotating a certain angle circumferentially, allowing the patient to adjust the position of the semi-circular block 15 inside the tapered groove 16 according to the rehabilitation condition of the ankle joint, avoiding excessive movement angle during ankle joint rehabilitation exercise, and swelling and pain that cannot be relieved appear at the ankle joint the next day, affecting the rehabilitation of the ankle joint. After the patient adjusts the position of the bolt 14 inside the rotating part 13 to increase the circumferential movement range of the ankle joint, the patient can perform circumduction exercise of the ankle joint to exercise the circumference of the ankle joint, increase the circumferential mobility of the ankle joint, and exercise all directions of the ankle joint, exercise other directions except the plantar flexion, dorsiflexion and inversion / eversion movement directions of the ankle joint, and improve the mobility of all directions of the ankle joint circumference.

[0042] The patient can pull out the U-shaped limiting rod 17 from inside the connecting block 10 and insert it into the inside of the first slot 18 and the second slot 19. After the U-shaped limiting rod 17 is inserted into the inside of the second slot 19, the U-shaped limiting rod 17 will limit the rotation direction of the bolt 14 and the semi-circular block 15, so that the bolt 14 and the semi-circular block 15 can only rotate when the patient exercises the ankle joint for inversion and eversion, thereby enabling the patient to specifically exercise the ankle joint for inversion and eversion, avoiding deviation in the angle of ankle joint inversion and eversion exercise, forming an incorrect ankle joint inversion and eversion angle, and affecting the rehabilitation of the ankle joint. After the U-shaped limiting rod 17 is inserted into the inside of the first slot 18, the bolt 14 and the semi-circular block 15 can only rotate when the patient's ankle joint performs plantar flexion and dorsiflexion activities, allowing the patient to specifically exercise plantar flexion and dorsiflexion activities, avoiding deviation in the angle of plantar flexion and dorsiflexion exercise of the ankle joint, forming incorrect plantar flexion and dorsiflexion angles, and affecting the walking gait after rehabilitation. At the same time, after the U-shaped limiting rod 17 is inserted into the inside of the first slot 18, the U-shaped limiting rod 17 will push the clamping block 20 into the inside of the clamping groove 21, fixing the L-shaped support piece 9 and the connecting block 10 together. When the patient performs walking exercise, the weight of the patient's body will be transmitted to the rotating member 13 through the binding piece 22, so that the rotating member 13 is transmitted to the connecting block 10 through the limiting member 12, and the fixed L-shaped support piece 9 and the connecting block 10 are transmitted to the connecting piece 7 and the shoe, enabling the patient to reduce the weight borne by the ankle joint and relieve the pressure on the ankle joint at the initial stage of walking exercise.

[0043] The working process of the technical solution provided by the present invention is as follows:

[0044] When the ankle joint needs to be fixed at the initial stage after the patient's ankle joint surgery, the insole 1 can be placed in the shoe, so that the shoe upper is stuck in the gap between the L-shaped support piece 9 and the connecting block 10. Then the shoe can be worn on the foot with the ankle joint surgery, so that the sole contacts the outermost foot pad sleeve of the insole 1. At this time, the insole 1 can be fixed to the foot through the first magic tape 8, and the shoelaces are tied, so that the foot is fixed inside the shoe. After the binding piece 22 and the connecting band 24 are wound around the calf part of the ankle joint surgery, the second magic tape 25 is passed through the insertion ring 26, and the part of the second magic tape 25 passing through the insertion ring 26 is attached to the part of the second magic tape 25 that does not pass through the insertion ring 26 to fix the binding piece 22 and the connecting band 24. Then the bolt 14 is rotated, so that the bolt 14 rotates along the inside of the rotating member 13 until the bolt 14 drives the semi-circular block 15 to abut against the bottom of the conical groove 16. At this time, the connecting block 10 and the rotating member 13 are fixedly connected together through the bolt 14, the semi-circular block 15 and the conical groove 16 and cannot rotate, thereby fixing the foot and the calf and preventing rotation, and fixing the ankle joint.

[0045] It should be noted that when rehabilitation exercises for the ankle joint are required, the connecting block 10 fixed to the foot will rotate together with the foot according to the rehabilitation exercises of the ankle joint, causing the tapered groove 16 on the connecting block 10 to rotate relative to the semi-circular block 15 until it stops after abutting against the semi-circular block 15. At this time, the movement of the patient's ankle joint is blocked and limited, allowing the patient to adjust the position of the semi-circular block 15 inside the tapered groove 16 according to the rehabilitation condition of the ankle joint, avoiding excessive movement angles during the rehabilitation exercises of the ankle joint, and preventing the occurrence of unrelievable swelling and pain at the ankle joint the next day, which may affect the rehabilitation of the ankle joint. It should be noted that after the U-shaped limiting rod 17 is inserted into the second slot 19, the U-shaped limiting rod 17 will limit the rotation direction of the bolt 14 and the semi-circular block 15, so that the bolt 14 and the semi-circular block 15 can only rotate when the patient's ankle joint performs inversion and eversion exercises. Thus, the patient can specifically perform inversion and eversion exercises of the ankle joint. After the U-shaped limiting rod 17 is inserted into the first slot 18, the bolt 14 and the semi-circular block 15 can only rotate when the patient's ankle joint performs plantar flexion and dorsiflexion activities, enabling the patient to specifically perform plantar flexion and dorsiflexion activities exercises, avoiding deviation in the angles of plantar flexion and dorsiflexion activities exercises of the ankle joint and forming incorrect plantar flexion and dorsiflexion angles, which may affect the walking gait after rehabilitation.

To enable the public to have a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention. However, those skilled in the art can fully understand the present invention even without these detailed descriptions. Additionally, to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0047] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
