Description

Technical Field

[0001] The invention relates to the technical field of hallux valgus correctors, in particular to a hallux valgus corrector regulator which can be freely bent and adjusted for use. Background Art

[0002] Hallux valgus refers to a condition in which the joint between the big toe and the first metatarsal bone is tilted more than 15 degrees. Hallux valgus is caused by a variety of conditions, such as heredity, frequent wearing of high-heeled and pointed shoes, which causes the big toe to be excessively turned outward. In addition, flatfoot patients are more likely to develop hallux valgus. There are more female patients than male patients, and it is more common in middle-aged and elderly women. Those who are accustomed to wearing high-heeled and pointed shoes are also prone to the disease.

[0003] The main manifestations of hallux valgus are foot deformity and pain. The deformity is manifested by the valgus of the big toe, which deviates toward the other toes, and the metatarsal head at the base of the big toe is obviously protruding. When the deformity is severe, the protruding part of the metatarsal head may be hemispherical, and the second toe also protrudes toward the back of the foot due to squeezing. Most patients with severe deformity will experience varying degrees of pain. The pain is mainly because the protruding part of the metatarsal head is squeezed and rubbed by the shoe upper for a long time, causing local skin thickening and bone hyperplasia, and bursae and bursitis may occur under the skin, causing redness, swelling and pain.

[0004] At present, the existing correction regulators generally do not have the effect of automatically adjusting the correction angle according to the movement patterns of human toes. Even when the degree of hallux valgus is relatively serious, the toes can still perform normal and flexible joint activities of upward curling or downward contraction under the control of the human body, and even when the toes are forced to perform joint activities by external force, such as passive bending of the toes when stepping on a hard object while walking, the existing correction regulators mostly forcibly pull the toes outward to achieve correction. If the corresponding change of the correction angle cannot be achieved during the process of bending and other joint activities, it is easy to cause damage to the toes. For this reason, we provide a hallux valgus correction regulator that can freely bend and adjust the correction angle according to the movement patterns of the human toes. Summary of the invention

[0005] The purpose of the present invention is to provide a hallux valgus correction regulator that can be freely bent and adjusted for use, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a hallux valgus correction regulator that can be freely bent and adjusted, comprising a metatarsal fixing plate and a thumb fixing plate hinged on the metatarsal fixing plate, wherein the thumb fixing plate and the metatarsal fixing plate are respectively provided with a first wearing hole and a second wearing hole for satisfying the wearing of the thumb and metatarsal parts of the human body, the metatarsal fixing plate is provided with a hinge seat for installing the thumb fixing plate, the thumb fixing plate is provided with a hinge head for connecting the hinge seat, the hinge head drives the thumb fixing plate to rotate forward and backward relative to the hinge seat to generate a periodic change in the valgus angle of the thumb fixing plate, and when the angle between the thumb fixing plate and the metatarsal fixing plate is 180 degrees, the valgus angle of the thumb fixing plate is the maximum value;

[0007] The hinge seat is provided with a limiting sleeve for increasing the rotation stability of the thumb fixing plate, the hinge head is provided with a lever slider that can extend into the limiting sleeve, and the limiting sleeve is provided with a guide groove that matches the lever slider.

[0008] Preferably, the metatarsal fixing plate is integrally formed with the limiting sleeve and the articulation seat, the top of the articulation seat is provided with a connecting platform for guiding the articulation head, the upper surface of the connecting platform is arranged in an inclined shape, and the inner side of the articulation head is provided with a groove adapted to the connecting platform, and the periodic change of the eversion angle when the articulation head rotates forward and backward is realized by the cooperation between the inclined upper surface of the connecting platform and the groove.

[0009] Preferably, the thumb fixing plate is arranged in a spiral right-handed manner extending outward or in an arc-shaped plate-like manner extending outward.

[0010] Preferably, the hinge seat and the hinge head are provided with a countersunk hole 1 and a countersunk hole 2 at the axial center positions respectively, and the hinge seat and the hinge head are connected by installing a hinge shaft at the countersunk hole 1 and the countersunk hole 2.

[0011] Preferably, the thumb fixing plate is integrally formed with the hinged head and the lever slider.

[0012] Preferably, openings are arranged through the limiting sleeves at both ends of the guide groove.

[0013] Preferably, when the hinged head rotates forward or reversely to the position where the thumb fixing plate abuts against the end surfaces of both ends of the limiting sleeve, the lever slider rotates to the positions where it abuts against the end points at both ends of the guide groove.

[0014] Preferably, a lowering portion is provided at one end of the upper surface of the connecting platform close to the limiting sleeve for facilitating the insertion of the lever slider, the lowering portion is arranged in an inclined shape, and the limiting sleeve and the hinge seat at the lowering portion are provided with a channel for facilitating the insertion of the lever slider into the guide groove.

[0015] Preferably, when the thumb fixing plate is arranged in a spiral right-handed extension outward, a wearing strap is connected to the top end of the outer wall of the thumb fixing plate, one end of the wearing strap is connected to the thumb fixing plate by ultrasonic welding, and the end of the wearing strap away from the welding position is wrapped around the outer wall of the thumb fixing plate and passed through the wearing hole. Velcro and Velcro are respectively provided on the outer walls on both sides of the two ends of the wearing strap, and a buffer pad is connected to the inner side wall of the thumb fixing plate.

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

[0017] 1: The present invention can be freely bent to produce a better correction effect. During wearing and use, the metatarsal fixing plate is fixed to the metatarsal part of the human body by a strap to play a supporting and fixing role, produce a support point for correction and reduction and bear the supporting force. The thumb fixing plate is fixed to the toe part of the human body by a strap to play a role in connecting the toes. The thumb fixing plate's own valgus angle is used to correct the human toes. The product is set so that the maximum valgus angle of the thumb fixing plate relative to the metatarsal fixing plate is the shape and position that the normal human toes should be in when they are in a weak state. During the movement of the knuckles of the human toes when they are raised or pressed down, the flip angle of the thumb fixing plate can be reduced relative to the ground, so that there will be no activity risk caused by the existing products that always force the thumb to be corrected. In addition, in actual use, since the thumb fixing plate is arranged on one side symmetrical to the metatarsal fixing plate, Only then will the maximum correction angle, or the strongest correction force, be produced. Then, during the user's correction process, the change in the bending angle of the thumb fixing plate can produce a therapeutic correction effect on the user. For example, during use, since the maximum correction angle of the thumb fixing plate is parallel to the metatarsal fixing plate, the correction force that the user can feel at this time is the largest, or the discomfort caused by the correction is the strongest. When using it for the first time, the user may naturally want to obtain a comfortable feeling in the thumb area and bend the thumb in an autonomously controlled manner to experience an easy correction. As the number of wearing times increases or the correction effect becomes increasingly obvious, the acceptable correction force will gradually increase, and ultimately the thumb will be in a normal position and shape for the therapeutic correction purpose. Therefore, the present application can produce a safer and more effective correction effect.

[0018] 2: The present invention has good stability. The connecting platform with an inclined upper surface can not only realize the change of the valgus angle by rotating the thumb fixing plate, but also serve to increase the force contact area between the thumb fixing plate and the metatarsal fixing plate to increase the stability of the movable connection. Under the sliding support of the lever slider and the limiting sleeve, the movable connection between the thumb fixing plate and the metatarsal fixing plate is not only realized through the stable connecting platform. At this time, the connecting platform is also used as the lever support point between the thumb fixing plate and the metatarsal fixing plate. The connection between the thumb fixing plate and the metatarsal fixing plate exists not only between the hinge head and the hinge seat, but also between the connecting platform and the groove, and even more between the lever slider and the limiting sleeve. Therefore, the lever slider is used to increase the corrective force capacity of the thumb fixing plate, and the periodic change of the thumb valgus angle can be generated while the thumb fixing plate rotates forward and backward, thereby improving the stability of the overall use of the corrector.

[0019] 3: The present invention is easy to wear and use. When the thumb fixing plate is spiral-shaped, the spiral thumb fixing plate can be directly wrapped around the thumb for positioning. The human thumb can be used to determine and fix the installation position to be worn, so that the user can wear it conveniently and accurately when it is frequently used. When used for correction, it can be wrapped around the thumb and extend to the side of the thumb that is under force to produce a rigid correction effect of the thumb. Different from the traditional soft thumb fixing method of a strap, the spiral thumb fixing plate can produce a more uniform traction correction force and produce a better correction effect.

[0020] 4: The structure of the present invention is simple and ingenious, and the production cost is low. The entire side of the metatarsal fixation plate is manufactured by one-piece molding, and the entire side of the thumb fixation plate is manufactured by one-piece molding. The simple structure itself can produce a therapeutic correction effect of free bending. When assembling the finished product, it is only necessary to align the hinge joint with the hinge seat and then install the hinge shaft to complete the assembly and packaging. Especially when manual assembly is performed, the hinge joint and the hinge seat are manually aligned first. Generally, it may be necessary to manually maintain the alignment for clamping and fixing. At the hinge joint, the lever slider set will extend to the inner side of the limit sleeve to provide support force, so it is not easy to detach, easy to assemble and produce, and can reduce the production of finished products.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-5 The present invention provides an embodiment: a hallux valgus correction regulator that can be freely bent and adjusted, comprising a metatarsal fixing plate 6 for external support of the metatarsal part corresponding to the thumb to be corrected and a thumb fixing plate 12 for connecting with the thumb to be corrected, the thumb fixing plate 12 is hinged on the metatarsal fixing plate 6, the thumb to be corrected can be the thumb or the little finger, the thumb fixing plate 12 and the metatarsal fixing plate 6 are respectively provided with a wearing hole 11 and a wearing hole 2 13 for satisfying the wearing of the thumb and metatarsal part of the human body, the wearing hole 11 and the wearing hole 2 13 can be stably worn on the toes and metatarsal part by matching the thumb fixing plate 12 and the metatarsal fixing plate 6 with a strap, please refer to Figure 1 and Figure 4The present invention provides two specific structures of thumb fixing pieces 12 for connecting and fixing the corrected thumb, one of which is that the thumb fixing piece 12 can be arranged in a spiral right-handed outward extension, and the other is that the thumb fixing piece 12 can be arranged in an arc-shaped plate-shaped outward extension. The thumb fixing piece 12 arranged in a spiral right-handed outward extension is preferably used. The thumb fixing piece 12 arranged in a spiral right-handed outward extension can be directly wrapped around the human toes to determine the correction position when worn by the user, and one of the positions to be corrected is fixed and determined, so that when the metatarsal fixing piece 6 needs to be fixed again, it will be easier and more convenient. Furthermore, the thumb fixing plate 12 which is spirally arranged to the right and extends outward can be wrapped around the thumb and extend to the side where the thumb is under force when used for correction, so as to produce a hard correction effect of the thumb. Different from the traditional soft-fixing thumb method of a strap, the traction force generated by the correction can first act on the thumb fixing plate 12 and then the thumb fixing plate 12 can pull and correct the thumb. The spiral thumb fixing plate 12 can generate a more uniform traction correction force and produce a better correction effect. Regardless of whether it is a spiral or arc-shaped plate-shaped thumb fixing plate 12, its inner side is a curved and smooth human-like structure, which can better fit the arrangement of human toes.

[0029] Furthermore, the present invention provides a better wearing method when the thumb fixing piece 12 is arranged in a spiral right-handed extension outward, the top end of the outer wall of the thumb fixing piece 12 is connected to a wearing belt 14, one end of the wearing belt 14 is connected to the thumb fixing piece 12 by ultrasonic welding, the end of the wearing belt 14 away from the welding position is wrapped around the outer wall of the thumb fixing piece 12 and penetrated into the wearing hole 11, and in the initial wearing stage, the wearing belt 14 can be directly tightened and fixed with Velcro to achieve the purpose of quick wearing, Velcro and Velcro are respectively provided on the outer walls on both sides of the two ends of the wearing belt 14, and the Velcro should be set as long as possible to facilitate binding of thumbs of different thicknesses, the wearing belt 14 made of textile material can be wrapped by the outer side of the thumb fixing piece 12, so that the contact feeling of the adjacent fingers of the corrected thumb is better, and a buffer pad 15 is connected to the inner side wall of the thumb fixing piece 12, and the buffer pad 15 can be made of elastic and soft materials such as cotton or silicone to increase the comfort of thumb fixation and further increase the uniformity of force.

[0030] The following provides a specific hinge connection structure about the thumb fixing plate 12 and the metatarsal fixing plate 6, the metatarsal fixing plate 6 is provided with a hinge seat 9 for installing the thumb fixing plate 12, the thumb fixing plate 12 is provided with a hinge head 10 for connecting the hinge seat 9, the hinge seat 9 and the hinge head 10 are respectively provided with a countersunk hole 14 and a countersunk hole 21 at the axial position, the hinge head 10 is connected by pressing and fixing the outer side of the hinge seat 9, so that the rotating side is away from the toe part of the human body, the hinge head 10 and the hinge seat 9 as well as the thumb fixing plate 12 and the metatarsal fixing plate 6 are smooth and flat as a whole, and the hinge seat 9 and the hinge head 10 are connected by installing a hinge shaft at the countersunk hole 14 and the countersunk hole 21.

[0031] Different from the traditional thumb fixing plate 12 and the metatarsal fixing plate 6 producing an orbital effect along the hinge axis, the hinge head 10 provided in the present application can produce a periodic change in the eversion angle of the thumb fixing plate 12 when driving the thumb fixing plate 12 to rotate forward and backward relative to the hinge seat 9, and when the angle between the thumb fixing plate 12 and the metatarsal fixing plate 6 is 180 degrees, the eversion angle of the thumb fixing plate 12 is the maximum value. It should be noted that when the angle between the thumb fixing plate 12 and the metatarsal fixing plate 6 is 180 degrees, it is an ideal structure in the state of relaxation and restoration of the sole of the human body, so that the thumb fixing plate 12 is completely located on one side of the metatarsal fixing plate 6 symmetrically arranged on the connecting seat 9. Figure 1-4 The thumb fixing plate 12 and the metatarsal fixing plate 6 shown in the use state are both in the maximum eversion angle state when the angle is 180 degrees. In actual use, the shapes of the feet of different users are different. When the soles of the feet are in the reset and relaxed state, the angles between the toes and the metatarsals that need to be corrected may be different. Therefore, what needs to be clarified in the present application is that the state at the maximum eversion angle is the actual angle between the toes and the metatarsals that need to be corrected when the soles of the feet are in the reset and relaxed state. The more common 180-degree horizontal flat state is selected as a compromise, or it can be understood as the position state of the thumb relative to the metatarsal after correction. It is not ruled out that there may be users with a larger angle. Correspondingly, when there are such users, the actual maximum eversion angle state of the thumb fixing plate 12 and the metatarsal fixing plate 6 can even be customized and changed. Similarly, the connection structure of the thumb fixing plate 12 and the metatarsal fixing plate 6 with the maximum eversion angle under different angle states and the positive and negative rotation that can produce periodic changes should be included.

[0032] Specifically, a connecting platform 3 for guiding the hinge head 10 is provided on the top of the hinge seat 9, and the upper surface of the connecting platform 3 is arranged in an inclined shape, that is, the upper surface thickness of the connecting platform 3 on the side away from the metatarsal fixing plate 6 is the largest, and the thickness of the two sides extending from the thickest part to the metatarsal fixing plate 6 is reduced. The inner side of the hinge head 10 is provided with a groove adapted to the connecting platform 3, and the inclined upper surface of the connecting platform 3 cooperates with the groove to realize the periodic change of the valgus angle when the hinge head 10 rotates forward and backward. The periodic change is that when the thumb fixing plate 12 and the metatarsal fixing plate 6 are at an angle of 180 degrees, the valgus angle is at the maximum value state, producing the maximum thumb traction correction effect, and in the process of the human toe bending upward or downward phalanx activity, the flipping angle of the thumb fixing plate 12, that is, the outward correction angle can be relatively reduced to produce a periodic change, and the periodic rule is reset to the maximum - positive rotation gradually decreases - reverse rotation gradually increases - continuous reversal reaches the reset maximum - reverse again gradually Small - positive rotation gradually increases - continuous positive rotation to reach the maximum reset - positive rotation gradually decreases again..., and in actual use, since the thumb fixing plate 12 is arranged on one side symmetrical to the metatarsal fixing plate 6, the maximum correction angle will be generated, or it can be said that the strongest correction force is generated. Therefore, during the user's correction process, the change in the bending angle of the thumb fixing plate 12 is a kind of correction effect that can produce a therapeutic effect on the user. For example, during use, since the maximum correction angle of the thumb fixing plate 12 is the state required to be corrected, the correction force that the user can feel at this time is the largest, or the discomfort caused by the correction is the strongest. When using it for the first time, the user may naturally want to obtain a comfortable feeling in the thumb area and bend the thumb in an autonomously controlled manner to produce an easy correction experience. As the number of wearing times increases or the correction effect becomes increasingly obvious, the acceptable correction force will gradually increase, and eventually the thumb will be in a normal position and shape for the therapeutic correction purpose.

[0033] The hinge seat 9 is provided with a limit sleeve 7 for increasing the rotational connection stability of the thumb fixing plate 12, the metatarsal fixing plate 6 is integrally formed with the limit sleeve 7 and the hinge seat 9, the hinge head 10 is provided with a lever slider 2 that can extend to the inside of the limit sleeve 7, the thumb fixing plate 12 is integrally formed with the hinge head 10 and the lever slider 2, and the limit sleeve 7 is provided with a guide groove adapted to the lever slider 2, the guide groove is also designed to be a concave-convex arrangement generated by the periodic angle change of the forward and reverse rotation of the thumb fixing plate 12, and the connection platform 3 arranged obliquely on the upper surface together generates the thumb The fixing plate 12 has a periodic eversion angle change effect. At this time, the connection between the thumb fixing plate 12 and the metatarsal fixing plate 6 not only exists between the hinge head 10 and the hinge seat 9, but also exists between the connecting platform 3 and the groove, and even exists between the lever slider 2 and the limiting sleeve 7, so as to increase the correction force bearing capacity of the thumb fixing plate by using the lever slider. The corresponding metatarsal fixing plate 6 and the thumb fixing plate 12 can be made of the same material or different materials. The preferred hard plastic material is light in texture and strong enough to meet the use requirements. Other hard materials such as metal or ceramics are also acceptable, which will not be elaborated here.

[0034] The end of the upper surface of the connecting platform 3 close to the limiting sleeve 7 is provided with a lowering portion 5 for facilitating the insertion of the lever slider 2. The lowering portion 5 is arranged in an inclined shape. The lowering portion 5 reduces the thickness of the connecting platform 3 close to the limiting sleeve 7. The inclination angle of the lowering portion 5 is greater than the inclination angle of the upper surface of the connecting platform 3 used for adjusting the eversion angle of the thumb fixing plate 12. The lowering portion 5 should not occupy too large an area so as not to affect the flipping of the lever slider 2 and to facilitate the insertion and assembly. Further, in order to increase the stability of the connection between the hinge head 10 and the hinge seat 9, and to increase In order to improve the wear resistance of the lever slider 2, the outer side of the lever slider 2 can be spherical, and the corresponding internal guide groove of the limit sleeve 7 is also adapted, similar to the traditional "T"-shaped slide groove structure design. The limit sleeve 7 at the lower sliding part 5 and the hinge seat 9 are both provided with an open channel for facilitating the insertion of the lever slider 2 into the guide groove for use. The lever slider 2 can only slide smoothly in the guide groove after being inserted into the guide groove from the channel. The same effect is produced that the hinge head 10 is not easy to fall off compared to the hinge seat 9.

[0035] The limiting sleeves 7 at both ends of the guide groove are penetrated with openings 8, which are easy to squeeze out foreign matter and convenient to rotate. When the hinge head 10 rotates forward or reversely to the position where the thumb fixing plate 12 contacts the end faces of the limiting sleeve 7, the lever slider 2 rotates to contact the end points at both ends of the guide groove, respectively, and a limiting support effect is generated in both directions, thereby increasing the stability of use.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
