Description

Technical Field

[0001] The invention relates to the technical field of leg bone correction devices, and in particular to a leg bone correction and fixation auxiliary device. Background Art

[0002] As the leg bones grow rapidly, they are somewhat bent at birth. If not discovered and corrected in time, many people will develop X-shaped or O-shaped legs when they grow up, which is unsightly. In severe cases, the soles of the feet and ankles cannot be bent to 90 degrees, and the two legs become inconsistent in length, forming long and short legs, which seriously affects the patient's health.

[0003] In order to correct the leg bones, manufacturers have developed a variety of leg bone correction devices. For example, patent number 201610008177.5 is an invention patent for a leg bone corrector, which mainly includes an adjustment plate, a positioning plate and a lace; a positioning device protruding outward is provided on the bottom wall at one end of the positioning plate, and a positioning groove extending toward one end of the positioning device is provided on the top wall at the other end, and one or more positioning holes recessed into the positioning groove are provided on the bottom wall of the positioning plate below the positioning groove; the sleeve lengths of the adjustment plate and the positioning plate are adjusted to adapt to leg bones of different lengths, and the leg bone corrector is placed on the side opposite to the bending direction of the leg bone, so that the positioning device and the adjustment device are pressed against the two ends of the leg bone, and then the leg bone and the leg bone corrector are fastened together with a lace so that the leg bone is pulled toward the leg bone corrector, thereby playing a role in correcting the leg bone.

[0004] However, the force exerted by tying the strap and the leg bone corrector together is relatively small, and has limited effect on leg bone correction; moreover, the correction of the leg bones cannot be accurately measured, and cannot meet the requirements of visual correction.

[0005] Therefore, how to design a leg bone correction and fixation auxiliary device with simple structure, easy operation, large correction force and controllable correction is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0006] The invention provides a leg bone correction and fixation auxiliary device, which solves the technical problems of the existing leg bone correction and fixation auxiliary device having small correction force, limited correction effect and inability to measure the correction effect.

[0007] The technical solution of the present invention to solve the above technical problems is as follows: a leg bone correction and fixation auxiliary device, comprising: a fixed base ring, a rotating gear ring, a limiting component and a leg clamping component,

[0008] An annular sliding groove is provided on the inner ring wall of the fixed base ring, and a limiting groove is provided at the bottom of the sliding groove; the rotating gear ring rotates and slides in the sliding groove, and has teeth on its outer ring wall; the limiting assembly includes a gear, a tower spring and a limiting block, all of which are located in the limiting groove, the gear is arranged in parallel with the rotating gear ring and is meshed with the rotating gear ring; one end of the tower spring is fixed to the inner groove wall of the limiting groove; the limiting block is fixed to the other end of the tower spring and contacts the teeth of the gear, so that the rotating gear ring rotates in one direction;

[0009] The leg clamping assembly includes two clamping springs and two clamping leg parts. The two clamping springs are relatively arranged in the rotating gear ring and one end of each clamping leg is respectively fixed on the two opposite ring walls of the rotating gear ring; the two clamping leg parts are relatively arranged between the two clamping springs and are respectively fixed on the other end of the corresponding clamping springs. The two clamping leg parts can elastically clamp the deformed legs to correct the deformed legs as the rotating gear ring rotates unidirectionally.

[0010] The beneficial effects of the present invention are: it subverts the structure of the traditional leg bone correction and fixation auxiliary device, first uses two leg clamping parts elastically connected to the rotating gear ring to relatively clamp the deformed leg, and then rotates the rotating gear ring. Since the limiting block fixed with the tower spring contacts with the teeth of the gear, the gear is limited to only one-way rotation, and the two relatively arranged leg clamping parts can be linked to rotate only in one direction, thereby increasing the correction force of the deformed leg, controlling the leg correction angle, and avoiding excessive leg correction angle, causing discomfort to the user when wearing.

[0011] Based on the above technical solution, the present invention can also be improved as follows.

[0012] Furthermore, it also includes multiple connecting rods, the fixed base ring, the rotating gear ring, the limiting assembly and the clamping leg assembly are at least two and are arranged in parallel in groups; the rod walls of the multiple connecting rods are fixed on the inner ring walls of at least two rotating gear rings at intervals; the two opposite clamping leg parts are distributed between the two adjacent connecting rods.

[0013] A further beneficial effect of the above arrangement is that by arranging at least two fixed base rings, at least two rotating gear rings, at least two leg clamping assemblies and at least two limiting assemblies in parallel in groups, multiple leg clamping assemblies can be fastened outside the deformed leg to improve the correction force of the deformed leg.

[0014] Furthermore, it also includes an operating knob, and the top of the fixed base ring is provided with an operating groove communicated with the limiting groove; the operating knob passes through the operating groove and extends into the limiting groove, and its extending end extending into the limiting groove is fixed on the gear to drive the gear to rotate.

[0015] A further beneficial effect of the above method is that by rotating the operating knob to drive the gear to rotate, the rotation angle of the rotating gear ring can be easily changed, the correction angle of the deformed leg can be adjusted, and the purpose of gradually correcting the deformed leg can be achieved.

[0016] Furthermore, an angle value is engraved on the top of the fixed base ring corresponding to the outer peripheral side of the operating knob.

[0017] A further beneficial effect of the above method is that by recording the angle values ​​before and after correction, the correction angle of the deformed leg can be accurately measured.

[0018] Furthermore, the two leg clamping parts each include a clamping plate, a buffer spring and a leg clamping plate, the two clamping plates are relatively placed between the two clamping springs and the side plates thereof away from each other are respectively fixed to the other ends of the two clamping springs; the two buffer springs are relatively placed between the two clamping plates and one ends thereof are respectively fixed to the side plates of the two clamping plates close to each other; the two leg clamping plates are relatively placed between the two buffer springs and the side plates thereof away from each other are respectively fixed to the other ends of the two buffer springs; the deformed leg is clamped by the two leg clamping plates.

[0019] The further beneficial effect of adopting the above method is: utilizing the dual elastic force of the clamping spring and the buffer spring to compress the two relatively arranged leg clamping plates to clamp the deformed leg, thereby increasing the clamping force and preventing it from falling off.

[0020] Furthermore, the two leg clamping parts each include a flexible plate, and one side surface of the two flexible plates is respectively fixed on one side surface of the two leg clamping plates close to each other; the deformed leg is clamped on the two flexible plates.

[0021] Furthermore, the flexible board is made of flexible material.

[0022] Furthermore, the two clamping plates, the two leg clamping plates and the two flexible plates are all arc-shaped structures. BRIEF DESCRIPTION OF THE DRAWINGS
