Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a hallux valgus prevention and correction device. Background Art

[0002] Hallux valgus refers to a tilt of the joint between the big toe and the first metatarsal bone exceeding 15 degrees. Hallux valgus is caused by a variety of conditions, such as heredity, frequent wearing of high heels or pointed shoes, which causes the big toe to be excessively turned outward. Flatfoot patients are more likely to develop hallux valgus.

[0003] At present, a Chinese utility model with announcement number CN212015896U discloses "A novel combined device for postoperative fixation of hallux valgus", comprising: a first fixing plate, a second fixing plate, a first fixing belt, a second fixing belt and a top pressure pad; wherein, one end of the first fixing plate is connected to one end of the second fixing plate, the first fixing plate is provided with a first fixing hole, and the second fixing plate is provided with a second fixing hole; the first fixing belt is passed through the first fixing hole, and the second fixing belt is passed through the second fixing hole; one end of the top pressure pad is connected to one side of the second fixing plate, and the other end is used to push against the distal end of the osteotomy to maintain the displacement of the distal end of the osteotomy to the outside and ensure the stability of the osteotomy end, and the distal end of the osteotomy is pushed against the top pressure pad connected to the second fixing plate to maintain the stability of the osteotomy end, ensure that the hallux valgus is in a normal position after correction, avoid displacement of the osteotomy end, and thus prevent recurrence of hallux valgus.

[0004] Although the above-mentioned combined device for postoperative fixation of hallux valgus has certain advantages in the fixation effect of hallux valgus, since the degree of hallux valgus of each person is different, the adjustment angle of the hallux valgus corrector is fixed, and the thumb position cannot be adjusted according to the condition and the patient's tolerance. For patients with a large angle of hallux valgus, a correction of too large an angle at one time may easily cause the patient to be unable to bear the correction pain. Utility Model Content

[0028] See also Figure 4-7 The knob assembly 48 includes a circular frame 481, a limiting ring 482, a ratchet 483, a knob 484, a pawl 485, a connecting shaft 486, a tension spring 487, a connecting rod 488, a button 489 and a connecting ring 4810. A limiting ring 482 is provided on the front side of the outer wall of the circular frame 481, a ratchet 483 is fixed at the center of the inner rear wall of the circular frame 481, and the knob 484 is embedded in the circular frame 481. A pawl 485 is provided on the inner rear side of the circular frame 481, and the pawl 485 is rotatably connected to the knob 484 through the connecting shaft 486. The pawl 485 is elastically connected to the inner wall of the knob 484 through a tension spring 487, the pawl 485 and the ratchet 483 are meshed with each other, the front end middle part of the pawl 485 is rotatably connected to one end of the connecting rod 488 through a rotating shaft, and the front end of the connecting rod 488 is rotatably connected to the button 489 through a rotating shaft, and the button 489 is embedded in the middle of the front end surface of the knob 484, and the outer wall of the knob 484 is provided with a connecting ring 4810, and the connecting ring 4810 is connected to the traction rope 46, the rear end of the circular frame 481 is fixedly connected to the side plate 1, and the support plate 41 rotates along the outer wall of the circular frame 481;

[0029] The inner wall of the support plate 41 fits with the outer wall of the circular frame 481, and the surface of the circular frame 481 is smooth, so that the support plate 41 rotates along the surface of the circular frame 481, and the rear side wall of the limiting ring 482 fits with the support plate 41, and the forward movement of the support plate 41 is limited by the limiting ring 482. The circular frame 481, the ratchet 483 and the knob 484 are arranged with the same center of a circle to ensure the meshing effect of the ratchet 483 and the pawl 485. The rotating shaft at the connection between the pawl 485 and the connecting rod 488 is two rotating shafts that intersect with each other, and one is rotatably connected to the pawl 485, and the other is rotatably connected to the connecting rod 488 to prevent the connecting rod 488 from affecting the pawl 485 to rotate outward along the connecting rotating shaft 486. The connecting rod 488 is inclined and tilted outward from front to back, so that when the button 489 is pressed backward, the pawl 485 is pushed to rotate outward along the connecting rotating shaft 486 through the connecting rod 488.

[0030] In summary, when in use, the sole connecting strap 2 is first connected to the sole of the patient's foot, and the thumb connecting strap 44 is connected to the thumb that needs to be corrected for hallux valgus;

[0031] The correction position of the thumb is adjusted according to the hallux valgus condition and the patient's tolerance. By turning the knob 484 clockwise, the knob 484 drives the pawl 485 to rotate along the outer wall of the ratchet 483, and the pawl 485 is pulled by the tension spring 487 to ensure the engagement of the pawl 485 with the ratchet 483 to prevent the knob 484 from reversing by itself. The knob 484 is rotated clockwise to pull the support plate 2 43 forward through the traction rope 46, and the support plate 2 43 drives the thumb to rotate through the thumb connecting belt 44, so that the thumb can be adjusted to the required correction angle.

[0032] When the rotation angle of the support plate 43 needs to be adjusted, the button 489 is pressed backwards, and the button 489 pushes the pawl 485 to rotate outward along the connecting shaft 486 through the connecting rod 488, disconnecting the engagement between the pawl 485 and the ratchet 483, and then the knob 484 is reversed, so that the support plate 43 can rotate outwards;

[0033] When the user wears the corrector and walks, the support plate 41 rotates along the surface of the circular frame 481, which does not affect the user's walking. The user can also perform walking training during the correction process to increase the correction effect of hallux valgus.

[0034] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.

[0035] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
