Description

Hallux corrector TECHNICAL FIELD

[0001] The present application relates to the technical field of medical auxiliary devices, and particularly relates to a hallux corrector. BACKGROUND

[0002] In the field of medical auxiliary devices, the correction treatment of foot deformity, especially toe deformity, has always been the focus of research. At present, the common toe deformity is hallux deviation, and the hallux deviates to one side of the adjacent toe, causing crowding, causing pain when walking or breeding bacteria to form athlete's foot, etc. The hallux deformity needs to be corrected by a hallux corrector to make the hallux return to the correct straightening direction. The common hallux corrector in the industry includes a foot side support plate, a hallux support plate rotationally connected with the foot side support plate, and a deviation correction adjusting structure arranged at the connection between the foot side support plate and the hallux support plate. The deviation correction adjusting structure is used to drive the hallux support plate to move relative to the foot side, that is, to drive the hallux to be separated from the adjacent toe by a certain distance, so as to realize correction adjustment. In the existing hallux corrector, the deviation correction adjusting structure has a push rod structure, that is, a push rod is arranged to be movable relative to the foot side support plate and the hallux support plate. The push rod is abutted on one side of the foot body, and then the push rod is driven to move, so that the foot side support plate and the hallux support plate connected with the push rod move along the push rod. It can be considered that the foot side support plate and the hallux support plate are adjusted in tension relative to the foot body. Since the foot side support plate is fixedly bound to the foot body, the main degree of freedom of the foot side support plate is the tightness of the binding band, and the foot side support plate has small degree of freedom of deflection. The hallux has a certain lateral swing degree of freedom, and the hallux and the hallux support plate can be integrally moved laterally. Therefore, during adjustment, the tension force mainly acts on the hallux end, which drives the hallux support plate and the hallux to move laterally, so as to realize distance adjustment of the hallux lateral movement.

[0003] With the continuous progress of medical technology, people's requirements for toe correctors are also increasing, hoping that they can not only provide effective correction effect, but also ensure the comfort and use experience of patients. There are various types of toe correctors on the market at present, but most of them have the problems of fixed structure and poor adaptability. These correctors often cannot be accurately adjusted according to the degree of toe deformity and individual differences of patients, resulting in poor correction effect or discomfort during use. In addition, although some correctors have a certain adjustment accuracy, the adjustment process is not smooth, such as the toe corrector in the industry, the deviation adjustment structure of the thumb corrector is designed with a threaded knob structure, a push rod is pushed on the threaded cap through the threaded hole in the center of the lifting rod, and the threaded cap is rotated to force the push rod to rise and fall. The threaded knob structure is formed by forming a longitudinal guide protrusion or guide groove on the outer wall of the lifting rod, and the guide protrusion or guide groove is matched with the corresponding guide groove or guide protrusion on the lateral support plate or the thumb support plate, so that when the threaded cap is rotated, the push rod will not rotate with the threaded cap, and the push rod will rise and fall along the guide groove. However, the threaded knob structure has high processing and matching precision requirements for the guide protrusion and the guide groove, otherwise it is easy to cause the push rod to shake in the circumferential direction or not to slide smoothly up and down, and even to cause the phenomenon of jamming during adjustment, which affects the use experience of patients.

[0004] Therefore, it is an urgent problem to be solved in the technical field of medical auxiliary devices to design a thumb corrector which is convenient to process and not easy to jam during operation.

[0018] Further, the shaft sleeve seat has an axial hole. The threaded sleeve is inserted into the axial hole of the shaft sleeve seat adjacent to the top end of the shaft sleeve seat. The rotating cap is rotatably sleeved on the outer periphery of the rotating cylinder. The inner top end of the rotating cylinder has a peripheral edge. The diameter of the hole surrounded by the peripheral edge is smaller than that of the limiting ring. The peripheral edge of the rotating cylinder is clamped between the rotating cap and the limiting ring.

[0019] Further, the big toe supporting piece comprises a curved plate matched with the side of the big toe, and a U-shaped slot formed at one end of the curved plate, which is clamped into the outer circumferential surface of the shaft sleeve base to realize the rotary connection.

[0020] Further, the big toe corrector further comprises a joint pad mounted on the push plate for abutting the metatarsophalangeal joint, and the outer surface of the inner side shell is provided with an elastic gasket.

[0021] Further, the lateral foot supporting piece has multiple types with different matching angles, and the corresponding lateral foot supporting piece can be selectively inserted into the outer periphery of the shaft sleeve base according to the degree of deviation of the big toe.

[0022] Further, the lateral foot supporting piece is provided with a first connecting slot for connecting the first binding belt, and the big toe supporting piece is provided with a second connecting slot for connecting the second binding belt.

[0023] Further, the outer periphery of the limiting guide piece is formed with a plurality of reinforcing ribs integrally connected to the push plate, and the circumferential side of the guide hole on the inner arc-shaped plate is provided with a corresponding cutout for matching the reinforcing ribs.

[0024] The present application has the following advantages:

[0025] Compared with the prior art, the big toe corrector of the present application can accurately correct the deformity of the big toe through the cooperation of the lateral foot supporting piece and the big toe supporting piece. The lateral foot supporting piece abuts the metatarsal bone of the sole to provide a stable support basis for the corrector, and the big toe supporting piece closely abuts the lateral surface of the big toe to ensure that the correction force can accurately act on the key position. In addition, the design of the abutting and pushing piece allows the user to accurately adjust the abutting force of the push plate on the metatarsophalangeal joint by rotating the knob, thereby realizing personalized accurate correction and improving the correction effect. Whether it is different foot types, different degrees of deformity, or different age groups of users, they can find the most suitable correction state through simple adjustment. This strong individualized adaptability greatly improves the use effect and user experience of the corrector.

[0026] The big toe corrector of the present application is provided with a limiting guide piece which is slidably arranged in the guide hole of the lateral foot supporting piece, without the cooperation of the guide protrusion and the guide slot, which is convenient to process and will not jam during use. At the same time, the connecting shaft, the threaded sleeve and the stud are connected, the stud is slidably sleeved on the connecting shaft, and the stud is prevented from being screwed out of the threaded sleeve and falling off.

Detailed Implementation

[0039] The specific embodiments of the present application are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0040] As shown in FIGS. 1-5, the present application provides a hallux corrector, which includes a lateral foot support 1, a hallux support 2, a pushing piece 3, and a knob 4. The lateral foot support 1 is rotationally connected with the hallux support 2. The lateral foot support 1 is used to be worn on the sole of the foot to be supported on one side of the sole. The hallux support 2 is used to be worn on the hallux and to be supported on the lateral surface of the hallux. The pushing piece 3 includes a pushing plate 31 for supporting the lateral metatarsophalangeal joint, a stud 32 and a limiting guide 33 standing on the pushing plate 31. The knob 4 is rotationally installed at the rotationally connected position of the lateral foot support 1 and the hallux support 2, and includes a threaded sleeve 41 with internal threads screwed on the stud 32. The lateral foot support 1 is provided with a guide hole 10, and the limiting guide 33 is slidably arranged in the guide hole 10 of the lateral foot support 1. The pushing plate 31 and the knob 4 are respectively located on both sides of the lateral foot support 1, so as to adjust the position by rotating the knob 4 to drive the stud 32 and the pushing plate 31 to slide along the sliding direction of the limiting guide 33, thereby adjusting the force of the pushing plate 31 supported on the metatarsophalangeal joint.

[0041] The hallux corrector of the present application can accurately correct the deformity of the hallux through the cooperation of the lateral foot support 1 and the hallux support 2. The lateral foot support 1 is supported on the metatarsal bone of the sole to provide a stable support basis for the corrector, and the hallux support 2 closely adheres to the lateral surface of the hallux to ensure that the correction force can accurately act on the key position. In addition, the design of the pushing piece 3 allows the user to accurately adjust the supporting force of the pushing plate 31 on the metatarsophalangeal joint by rotating the knob 4, thereby realizing personalized accurate correction and improving the correction effect. Whether it is different foot types, different deformity degrees, or different age groups of users, they can find the most suitable correction state through simple adjustment. The strong individualized adaptability greatly improves the use effect and user experience of the corrector.

[0042] The hallux corrector of the present application fully considers the comfort of the user in design. The lateral foot support 1 and the hallux support 2 can adopt ergonomic design to fit the shape of the sole and the hallux, reducing friction and compression. At the same time, the operation of the pushing piece 3 and the knob 4 is simple and convenient, which will not bring additional trouble to the user. The high comfort design makes the user can wear the corrector for a longer time, thereby accelerating the correction process.

[0043] The toe corrector of the present application is compact in structure and easy to operate. The user can wear and adjust the toe corrector in a few simple steps without the assistance of professionals. Meanwhile, the toe corrector is small in size and easy to carry, and the user can wear it at any time in daily life without being restricted by time and place.

[0044] In order to avoid the pushing piece 3 from being detached from the threaded sleeve 41 when the knob 4 is rotated, the toe corrector further comprises a connecting shaft 5 which is arranged in the threaded sleeve 41 and the stud 32, the stud 32 being slidably sleeved on the connecting shaft 5, and the connecting shaft 5 having limiting portions at both ends to limit the axial direction, thereby preventing the stud 32 and the threaded sleeve 41 from being detached from each other.

[0045] In the preferred embodiment of the present application, the threaded sleeve 41 has a sleeve portion and an end wall portion formed at one end of the sleeve portion, and one end of the connecting shaft 5 extends into the sleeve portion and is fixedly connected with the end wall portion; a sleeve hole is formed on the pushing plate 31 corresponding to the central axis position of the stud 32, the sleeve hole extends along the central axis of the stud 32 to the end of the stud 32, a through hole is formed on the end surface of the end of the stud 32 and communicates with the sleeve hole, the diameter of the through hole is smaller than that of the sleeve hole, the other end of the connecting shaft 5 is sleeved in the sleeve hole through the through hole, and the limiting portion of the other end of the connecting shaft 5 cannot pass through the through hole, thereby limiting the stud 32 from being detached from the connecting shaft 5.

[0046] When the threaded sleeve 41 is rotated, the axial position of the threaded sleeve 41 is limited, that is, it can only be rotated and cannot be lifted, which forces the stud 32 to be lifted along the connecting shaft 5, and the maximum stroke of the lifting is stopped when the stud 32 slides to the limiting portion of the connecting shaft 5. In this way, the connecting shaft 5 can not only avoid the pushing piece 3 from being detached when the knob 4 is rotated, but also provide a guiding effect for the sliding of the stud 32, the central position of the stud 32 can be smoothly lowered, the sliding adjustment is more smooth, and the connection stability of the knob 4 and the pushing piece 3 is improved. In the embodiment, the limiting portions at both ends of the connecting shaft 5 adopt rivet structures, which are simple to process, easy to assemble and low in cost. Understandably, the end of the connecting shaft 5 connected in the threaded sleeve 41 can also not be fixedly connected with the threaded sleeve 41. The stud 32 and the threaded sleeve 41 can be slidably connected on the connecting shaft 5 only through the connecting shaft 5, so as to prevent the stud 32 from sliding off the threaded sleeve 41.

[0047] The knob 4 further comprises a rotating cap 42 fixedly sleeved at one end of the threaded sleeve 41, and the inner periphery of the rotating cap 42 has a gap with the outer periphery of the threaded sleeve 41.

[0048] One end of the threaded sleeve 41 has a limiting ring 44 which is installed at one end of the end wall portion of the threaded sleeve 41. Preferably, the limiting ring 44 and the end wall portion can be integrated, and the limiting ring 44 is rotatably installed on the inner side of the lateral foot support 1. The rotating cap 42 is rotatably installed on the outer side of the lateral foot support 1, and the rotating cap 42 is connected with the limiting ring 44 through a pin shaft passing through the lateral foot support 1.

[0049] By optimizing the structure of the knob 4, the adjustment convenience is enhanced, and the installation and disassembly efficiency is improved, not only the durability and stability of the corrector are improved, but also the user has a more convenient and comfortable use experience. In order to improve the comfort of use, the hallux corrector provided by the application further comprises a joint pad 6 mounted on the push plate 31 for abutting the metatarsophalangeal joint, and the joint pad 6 can be made of elastic material such as silica gel.

[0050] In this embodiment, the first connecting groove 100 is provided on the lateral support 1 to connect the first binding belt 7. The lateral support 1 is worn on the foot through the first binding belt 7.

[0051] In this embodiment, the lateral support 1 includes an inner shell 11 and an outer shell 12 detachably mounted on the inner shell 11. The inner shell 11 includes an inner arc-shaped plate 111 matched with the metatarsal bones on the sole side and a shaft sleeve seat 112 formed at one end of the inner arc-shaped plate 111. The outer periphery of the shaft sleeve seat 112 is formed with a step in the axial direction, and the shaft sleeve seat 112 has a hollow shaft hole penetrating through the inner arc-shaped plate 111, and the shaft hole is provided for the threaded sleeve 41 to pass through. The guide hole 10 is provided on the inner arc-shaped plate 111 adjacent to the shaft sleeve seat 112.

[0052] The outer shell 12 includes an outer arc-shaped plate 121 connected to the inner arc-shaped plate 111 and a rotating cylinder 122 formed at one end of the outer arc-shaped plate 121. The outer arc-shaped plate 121 is fixedly mounted on the inner arc-shaped plate 111 and axially limits the position of the hallux support 2. The rotating cylinder 122 has a hollow cylinder portion, the rotating cylinder 122 is sleeved on the shaft sleeve seat 112, the threaded sleeve 41 is inserted into the shaft hole of the shaft sleeve seat 112 adjacent to the top end of the shaft sleeve seat 112, the screw cap 42 is rotatably sleeved on the outer periphery of the rotating cylinder 122, and the screw cap 42 is fixedly connected with the limiting ring 44 through the pin shaft.

[0053] The threaded sleeve 41 is screwed with the threaded sleeve 32, and the threaded sleeve 41 is rotated by rotating the screw cap 42. Since the threaded sleeve 32 and the limiting guide 33 are fixedly arranged on the push plate 31, the limiting guide 33 is inserted into the guide hole 10, so that when the threaded sleeve 41 rotates, the threaded sleeve 32 does not rotate together with the threaded sleeve 41, and the rotation of the threaded sleeve 41 forces the threaded sleeve 32 to move axially.

[0054] It can be understood that the lateral foot support 1 is matched to the medial foot support 11 by adopting the structure that the lateral shell 12 is matched to the medial shell 11, the medial shell 11 is used to be attached to the lateral foot, and the big toe support 2 is rotatably connected to the medial shell 11. By arranging the lateral shell 12, the axial position of the threaded sleeve 41 is limited when the threaded sleeve 41 rotates, that is, the threaded sleeve 41 does not ascend and descend relative to the lateral foot support 1 when rotating. Specifically, the inner top end of the rotating cylinder 122 of the lateral shell 12 is formed with a periphery 1221, the diameter of the hole surrounded by the periphery 1221 is smaller than the diameter of the limiting ring 44, so that after the threaded sleeve 41 penetrates into the rotating cylinder 122, the screw cap 42 is connected with the threaded sleeve 41 through the screw 43, so that the periphery 1221 of the rotating cylinder 122 is clamped between the plate surface of the screw cap 42 and the limiting ring 44, and the screw cap 42 and the limiting ring 44 can rotate relative to the periphery 1221, so that the threaded sleeve 41 does not ascend and descend relative to the lateral foot support 1 when rotating. In order to improve the comfort of use, the outer surface of the medial shell 11 is provided with an elastic gasket 13, which is made of silica gel material. In the embodiment, the screw cap 42 is connected to the limiting ring 44 of the threaded sleeve 41 through two screws 43 (equivalent to a pin shaft), and it can be understood that the screw 43 penetrates through the sleeve hole surrounded by the periphery 1221, so that the screw 43 is not hindered when the screw cap 42 rotates.

[0055] In the embodiment, the big toe support 2 is provided with a second connecting groove 20 for connecting the second binding band 8. The big toe support 2 is bound to the big toe by the second binding band 8.

[0056] In the embodiment, the big toe support 2 includes a curved plate 21 matched with one side of the big toe, and a U-shaped groove 22 formed at one end of the curved plate 21. The U-shaped groove 22 clamps the outer periphery of the shaft sleeve seat 112 to realize the rotary connection. In this way, the big toe support 2 is easily installed on the shaft sleeve seat 112.

[0057] It can be understood that referring to FIG. 6, the big toe support 2 can be designed in multiple ways and have different matching angles. According to the degree of deviation of the big toe of the user, the big toe shape is selected and inserted into the outer periphery of the shaft sleeve seat and can rotate around the outer periphery of the shaft sleeve seat.

[0058] When the big toe corrector is used, the stud 32 is forced to move along the axial direction by rotating the rotary cap 42, and the stud 32 moves together with the limiting guide 33 and the push plate 31. When the threaded sleeve 41 pushes the stud 32 away from the threaded sleeve 41, the push plate 31 abuts against the lateral side of the foot, so that the lateral side support 1 and the big toe support 2 are pulled away from the sole side of the foot, and the lateral side support 1 is fixedly bound on the sole, and the length of the lateral side support 1 is relatively long, and the movable degree of the lateral side support 1 is mainly the tightness of the bound belt or the plastic deformation degree of the lateral side support 1 itself, and the movable degree of the lateral side support 1 is small, and the big toe has a certain lateral swing degree, and the big toe and the big toe support can move laterally together, so that the lateral side support 1 and the big toe support 2 can be considered as a whole when the big toe support 2 is adjusted, and the lateral side support 1 is taken as a fulcrum, that is, the end of the lateral side support 1 far away from the big toe is taken as a support point, and the lateral side support 1 swings, so that the big toe support plate and the big toe move laterally, and the swing degree is the largest, and the distance adjustment of the big toe is realized.

[0059] It is worth further explaining that the present application is not an easily conceivable alternative improvement of the deviation correction and adjustment structure in the industry, and the present application needs to overcome technical prejudice to be realized. The industry appears to set the knob as a stud, set a central threaded hole in the push rod, and form a limiting guide structure on the outer periphery of the push rod. This structure can be easily thought of by those skilled in the art. If the knob is set as a threaded hole structure and the push rod is set as a stud structure, the push rod is prone to fall off. Secondly, since the outer periphery of the push rod is threaded, it is not possible to set a limiting guide structure, which is not conducive to guiding. The present application realizes the setting of the knob as a threaded hole structure and the setting of the push rod as a stud structure, which requires creative labor. In order to avoid the clamping structure of the guide protrusion and the guide groove, the present application designs the big toe corrector structure to avoid the clamping situation during operation, and avoids the problem of the thin wall thickness of the push rod caused by the central threaded hole in the push rod, which is not durable. In summary, the big toe corrector provided by the present application has the beneficial effects of personalized adaptation, accurate adjustment of correction force, high wearing comfort and simple operation, and provides a high-efficiency and comfortable correction scheme for the user, which is expected to be widely applied and popularized in the field of medical auxiliary instruments.

[0060] Please refer to FIGS. 7-8, further, in order to strengthen the strength of the limiting guide 33, a plurality of reinforcing ribs 331 are formed on the outer periphery of the limiting guide 33, and the reinforcing ribs 331 are integrally connected to the push plate 31. Correspondingly, a corresponding cutout 101 is formed on the side of the guide hole 10 on the inner arc plate 111 to match the reinforcing ribs 331.

[0061] As long as the idea of the present application is not violated, any combination of various different embodiments of the present application should be considered as the disclosed content of the present application; within the technical concept of the present application, any combination of various simple modifications and different embodiments of the technical solutions without violating the idea of the present application should be within the protection scope of the present application.
