Description

Technical Field

[0001] The utility model relates to the field of foot rehabilitation equipment, in particular to a foot orthosis. Background Art

[0002] Foot drop, deformity and other foot diseases are common sequelae of stroke, hemiplegia or various types of nerve damage. Some patients with oral tumors develop grasping toes during the postoperative recovery period after the peroneal muscle flap is removed during surgery. Reasonable traction and correction of the foot is beneficial to the restoration of functional tissues such as muscles and ligaments, and is a common recovery method used by patients with foot diseases in daily life.

[0003] Common orthotics currently available on the market typically consist of a leg strap that wraps around the patient's calf, a foot strap that wraps around the patient's foot, and a traction strap connecting the two. One end of the traction strap is fixed to the leg strap, while the other end loops through a buckle on the foot strap and connects to the leg strap, pulling the foot. The traction strap can also be adjusted to varying pulling angles and forces by adjusting its tension.

[0004] However, the fixed buckle position on the foot straps of these traditional orthoses, which means the traction force applied to the foot, prevents patients from adjusting the straps according to their needs, resulting in unsatisfactory traction orthosis results. Furthermore, traditional orthoses either only provide orthotic effects on the foot or toes, leaving them lacking in functionality. Summary of the Invention

[0005] The utility model aims to provide a portable claw-type toe orthosis with adjustable traction force position.

[0006] In order to achieve the above-mentioned purpose of the invention, the technical solution adopted by the present invention is: a portable claw toe orthosis, including a foot strap for binding on the foot and a leg strap for binding on the calf, the foot strap is provided with an adjustable buckle mechanism that can adjust the position along the length direction of the instep, and the leg strap is provided with a foot traction strap with one end connected to the leg strap; the other end of the foot traction strap is connected to the front section of the foot traction strap or the leg strap after passing through the buckle.

[0007] Preferably, the adjustable buckle mechanism includes a connecting piece riveted to the foot strap, the top of the connecting piece is provided with a T-shaped guide ridge extending along the length direction of the instep, the guide ridge is adapted to be equipped with a slider that slides with the guide ridge, and the slider is locked or unlocked with the guide ridge through a locking assembly; a buckle is provided on the top of the slider.

[0008] Preferably, the pull buckle includes two short vertical plates symmetrically arranged on both sides of the top of the slider, and a pulling rod arranged between the short vertical plates; the two ends of the pulling rod are rotatably matched with the short vertical plates, and the length of the pulling rod is ≥ the width of the foot pulling strap.

[0009] Preferably, the locking assembly is a self-locking assembly, which includes a first locking tooth arranged at the bottom of both sides of the T-shaped head of the guide rib, and a second locking tooth is arranged on the surface of the slider opposite to the first locking tooth; the self-locking assembly also includes a sliding support plate arranged between the top surface of the guide rib and the inner top surface of the slider, and the sliding support plate and the slider are connected by a number of self-locking springs.

[0010] Preferably, the tail end of the foot traction strap passes around the drawstring and is connected to the front end of the foot traction strap with a hook and loop fastener.

[0011] Preferably, it also includes an elastic rubber toe pulling claw and a toe pulling strap, wherein the toe pulling claw is provided with five toe holes for the toes to pass through, and a pulling hole; one end of the toe pulling strap is connected to the leg strap, and the other end passes through the buckle and the pulling hole in sequence and is connected to the foot pulling strap with a Velcro.

[0012] The beneficial effects of the present invention are primarily reflected in the ability to quickly and easily adjust the position of the buckle on the instep, thereby finding the most suitable force-bearing position, providing greater comfort and improved orthopedic results. Specifically, during use, the leg and foot straps are secured to the user's calf and foot, respectively. The foot traction strap is then passed through the buckle, tension is adjusted, and the foot traction strap is secured. During tension adjustment, the buckle position can be adjusted first, thereby finding the most suitable traction force point based on individual user differences, ensuring comfort and effectiveness.

[0016] like Figure 1-3 As shown, a portable claw-type toe orthosis is mainly used for traction rehabilitation treatment of foot drop and foot deformation caused by neurological damage such as stroke and hemiplegia, or for stretching and relaxing the foot and leg muscles after exercise.

[0017] Similar to traditional orthotics, the present invention also includes a foot strap 1 for binding on the foot and a leg strap 2 for binding on the calf. Both the foot strap 1 and the leg strap 2 are generally made of a flexible composite material, including: an inner lining cloth, a surface layer and a filling layer, etc. In order to facilitate binding and adapt to the limb sizes of different people, the foot strap 1 and the leg strap 2 can be fixed with Velcro for easy operation.

[0018] However, since the buckle position of the traditional orthosis is fixed on the foot strap 1, for different people, the force point on the instep is fixed after it is worn, and it cannot be finely adaptively adjusted according to actual needs, which leads to poor comfort. For example, some people need the buckle to be closer to the toes, while some people need the buckle to be closer to the back.

[0019] The most significant difference of the present invention lies in the adjustable buckle mechanism 3, which features a pull ring on the foot strap 1 and allows for adjustment along the length of the instep. The leg strap 2 is equipped with a foot traction strap 4, one end of which is connected to the leg strap 2. The other end of the foot traction strap 4 passes through the buckle and connects to the front section of the foot traction strap 4 or the leg strap 2. The use of the adjustable buckle mechanism 3 allows for quick adjustment of the buckle's position to suit individual needs during use.

[0020] Of course, there are many ways to achieve this kind of adjustability. For example, multiple cloth buckles can be placed on the foot strap 1 at the position corresponding to the user's instep, with each buckle distributed along the length of the instep, allowing users to select the desired buckle as needed during use. This approach has the advantage of being simple and easy to implement. However, it has the disadvantage of only being able to arrange a limited number of buckles, making it impossible to achieve true arbitrary adjustment. Furthermore, since the buckle is typically a small cloth buckle sewn to the foot strap 1, its load-bearing conditions are less than ideal.

[0021] To this end, the present invention discloses an adjustable buckle mechanism 3 which is freely adjustable and has good structural strength. Figure 1 and 2 As shown in the figure, the adjustable buckle mechanism 3 includes a connecting piece 5 riveted to the foot strap 1. The connecting piece 5 is usually made of a thinner alloy or high-strength plastic and is fixed to the foot strap 1 by a number of rivets to ensure its good tensile strength.

[0022] The buckle is installed on a connecting piece 5. The top of the connecting piece 5 is equipped with a T-shaped guide rib 6 extending along the length of the instep. A slider 7 is fitted onto the guide rib 6, which slides in engagement with it. The slider 7 is locked and unlocked with the guide rib 6 via a locking assembly. The top of the slider 7 is equipped with a buckle. This buckle can take the form of a button-shaped component fixed to the top of the slider 7, through which the foot traction strap 4 is passed to achieve traction. However, since foot traction often involves relatively high forces, to achieve more labor-saving operation, the buckle of the present invention includes two short vertical plates 8 symmetrically arranged on either side of the top of the slider 7, and a traction rod 9 disposed between the short vertical plates 8. The ends of the traction rod 9 are in rotational engagement with the short vertical plates 8, and the length of the traction rod 9 is greater than or equal to the width of the foot traction strap 4. This way, during operation, the traction rod 9 acts as a movable pulley, saving more effort during traction.

[0023] When adjusting the position of the buckle, the present invention allows the slider 7 to slide along the guide rib 6, thereby adjusting the position of the buckle. Of course, after the adjustment is in place, the slider 7 needs to be locked. There are many specific locking methods. For example, the locking assembly is a locking bolt that is threaded onto the slider 7. After the adjustment is in place, the locking bolt is rotated so that its end contacts the guide rib 6 to achieve locking. The structure is very simple.

[0024] However, the above locking form requires a screwing component to achieve locking and unlocking, which is not convenient to use. At the same time, more than one locking bolt is often required to effectively lock. In order to improve the above situation, a better implementation form of the utility model is as follows: Figure 2 As shown in FIG, the locking assembly is a self-locking assembly, comprising first locking teeth 10 disposed at the bottom of both sides of the T-shaped head of the guide rib 6, and second locking teeth 11 disposed on the surface of the slider 7 opposite the first locking teeth 10. The self-locking assembly also includes a sliding support 12 disposed between the top surface of the guide rib 6 and the inner top surface of the slider 7. The sliding support 12 and the slider 7 are connected by a plurality of self-locking springs 13. Thus, when the position needs to be adjusted, the slider 7 is pressed downward, and the first and second locking teeth 10 and 11 are unlocked, allowing the slider 7 to slide normally along the guide rib 6. At the same time, due to the presence of the sliding support 12, the pressing pressure (the self-locking spring return force) can be effectively distributed throughout the sliding support 12, without affecting normal sliding. When the slider 7 is released, the slider 7 is reset under the action of the self-locking spring 13, at which time the first and second locking teeth 10 and 11 engage, and the slider 7 cannot slide on the guide rib 6. In addition, during stretching, the foot traction strap 4 does not apply a pressing force to the slider 7, but rather a relatively upward pulling force, so the overall locking is stable.

[0025] Regarding the fixing method of the foot traction strap 4 of the present invention, it can be fixed to its own front end after passing through the traction rod 9 of the present invention, or it can be fixed to the leg strap 2. Among them, the more common method is that the tail end of the foot traction strap 4 passes through the buckle and is connected to the front end of the foot traction strap 4 with a hook and loop fastener.

[0026] In addition to being able to pull the foot, the present invention also has another difference in that it also includes an elastic rubber toe pulling claw 14 and a toe pulling belt 15, which can achieve pulling correction of the toes. Figure 3 As shown in FIG, the toe traction claw 14 is provided with five toe holes 16 for the toes to pass through, as well as a traction hole 17. During use, the patient inserts their toes into the toe holes 16. One end of the toe traction strap 15 is connected to the leg strap 2, and the other end is passed through the buckle and traction hole 17, and then connected to the foot traction strap 4 with a Velcro fastener. Because toe traction requires relatively less force than foot traction, a single traction hole 17 for the toe traction strap 15 to pass through is sufficient.
