Description

A leg fixator for treating bone injuries in traditional Chinese medicine

Technical Field

The utility model relates to the technical field of leg supports, in particular to a leg fixator for treating bone injuries in traditional Chinese medicine.

Background Art

The tibia is the main bone that supports the body weight and connects to the lower part of the femur. The fibula is an important bone that attaches to the calf muscles. These two bones are often fractured due to external impact. In general, the treatment methods of fractures in traditional Chinese medicine include reduction, fixation, functional exercise, internal and external application. In detail, there are manual reduction, splint fixation, plaster fixation, skin traction, bone traction, closed reduction, Kirschner wire fixation, and external fixator fixation. As for splint fixation and plaster fixation, both of them clamp and fix the reduced fractured limb to allow the fracture ends to heal under relatively static conditions.

However, after the leg is wrapped and fixed, it cannot be used with force. Therefore, most patients either stay in bed or walk with crutches, which is very inconvenient. In addition, during the fracture rehabilitation period, it is necessary to insist on walking training, which can accelerate tissue healing, promote local swelling, and avoid muscle atrophy; it can also promote joint function recovery and prevent osteoporosis. Most walking training requires patients to walk slowly while holding the handrails, but sometimes when exerting force, the fracture end will suddenly pierce and be stressed, resulting in unstable standing and easy to fall.

To this end, the utility model provides a leg fixator for treating bone injuries in traditional Chinese medicine, which is convenient for daily activities and can prevent sudden toppling during walking training.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings 1-4 in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

Embodiment 1, in order to facilitate the daily life of fracture patients and make walking training more stable, in this embodiment, a leg fixator for treating bone injuries in traditional Chinese medicine is provided, including two arc-shaped splints 1 arranged symmetrically on the left and right, the inner diameters of the two splints 1 gradually decrease from top to bottom, and the overall appearance of the two splints 1 is S-shaped, the S-shaped splint 1 has four common bending points including the ends, and two adjacent bending points of the four bending points are arranged front and back alternately, the front bending point is wrapped around the front side of the leg, and the rear bending point is wrapped around the rear side of the leg. The two splints 1 use the S shape to wrap the leg as a whole to form an exoskeleton, which avoids the ventilation of the wound, promotes wound healing, avoids the wound from being infected and rotten, and can also prevent the splint 1 from being dislocated, so that the wrapping is more firm;

The upper ends of the two splints 1 are each provided with an arc-shaped support plate 2, and both ends of the two support plates 2 are connected and fixed by a connecting mechanism 3. The two support plates 2 are buckled under the knee joint and then cooperate with the S-shaped splint 1 to firmly fix the splint 1 on the leg. In this embodiment, the connecting mechanism 3 is any one of a cable tie buckle structure and a belt buckle structure, so that the tightening degree between the two support plates 2 can be adjusted according to the thickness of the patient's legs, thereby improving the practicality and applicability of the device, and metal wires are provided in the cable tie or belt buckle to improve the strength of the components and avoid the connection between the two support plates 2 from breaking due to the staggered force when subjected to force. Preferably, multiple groups of Velcro or straps are provided at vertical intervals between the two splints 1 to improve the clamping stability;

The lower ends of the two splints 1 are rotatably mounted with a rotating shaft 4, and the two rotating shafts 4 are fixedly connected with a pedal 5 via fasteners. An elastic airbag 6 is arranged on the pedal 5, and an trachea is arranged at the end of the airbag 6. A valve core is arranged at the tube mouth of the trachea, so as to inflate or release the air in the airbag 6. A sealing cover is threadedly mounted at the tube mouth of the trachea to protect the valve core and avoid leakage due to accidental contact. A binding mechanism is arranged on the side of the pedal 5, and the binding mechanism is any one of a binding strap, a cable tie, and a Velcro. When the fracture is just reduced, after the splint 1 is wrapped around the leg, the leg cannot exert force at all. At this time, the airbag 6 is deflated, and there is a gap between the sole of the foot and the airbag 6, or the airbag 6 is slightly bulged and fits with the sole of the foot, but the airbag 6 is not expanded, that is, the sole of the foot is not stressed. This is to prevent psychological fear caused by the sole of the foot being suspended in the air. At this time, after wearing the device, when the patient walks or lies down in daily life, the fractured part of the leg is covered by the splint 1, and the stress points are between the support plate 2 and the support plate 2. The knee joint and the fracture are not stressed, so the patient can walk slowly. Compared with the original need to use crutches and bend the legs to walk, the use of this device makes the daily life of patients with leg fractures more convenient; and when the patient has been treated for a period of time, he can carry out appropriate walking training, which requires force on the soles of the feet and a little force on the legs. At this time, air is inflated in the airbag 6, so that the airbag 6 expands and bulges, and the soles of the feet are slightly stressed. At this time, the legs are stressed when walking, which plays a training role, and the force is small. When walking, the fractured leg will not be stinging due to the weight of the body and suddenly bending the legs to cause tipping, making training safer, and as the airbag 6 is inflated more, the airbag 6 swells more, and the soles of the feet are stressed more. It is suitable for rehabilitation training and daily use in different rehabilitation periods; preferably, when the present device is used, the patient's leg fracture has been reset and is simply wrapped and fixed. When worn, the inner wall of the splint 1 is covered with an elastic mesh pad, making it more comfortable to wear.

Embodiment 2, in order to reduce the flexibility of the pedal 5 to adapt to the walking state under different rehabilitation states, in this embodiment, a limiting mechanism is provided between the rotating shaft 4 and the splint 1, and the limiting mechanism includes a braking mechanism and a damping mechanism:

The brake mechanism comprises a first screw rod 7 threadedly connected to the clamping plate 1, and a side plug hole 8 corresponding to the first screw rod 7 is provided on the side wall of the rotating shaft 4;

The damping mechanism comprises a second screw rod 9 threadedly connected to the clamping plate 1 , and a damping sleeve 10 is provided at the end of the second screw rod 9 for use in conjunction with the end of the rotating shaft 4 .

In the early stage of fracture recovery, when the leg cannot exert force, the first screw 7 is inserted into the insertion hole 8, thereby braking the shaft 4, which cannot rotate, thereby braking the pedal 5 to prevent the pedal 5 from easily deflecting and affecting the static state of the leg and the healing of the fracture;

In the middle stage of the fracture end recovery, the leg can exert a slight force and the ankle can move to a certain extent. At this time, the first screw rod 7 is screwed to separate the first screw rod 7 from the insertion hole 8, and the rotating shaft 4 loses the brake, and then the second screw rod 9 is screwed, and the second screw rod 9 drives the damping sleeve 10 to buckle at the end of the rotating shaft 4, thereby increasing the rotation resistance of the rotating shaft 4 and reducing the rotation flexibility of the rotating shaft 4;

In the later stage of fracture recovery, the legs can exert force and the ankles can swing flexibly. At this time, the second screw 9 is screwed to separate the damping sleeve 10 from the rotating shaft 4. At this time, the pedal 5 has the highest flexibility.

Embodiment 3, in order to reduce the load on the knee joint when wearing the device and alleviate the burden on the knee joint, in this embodiment, lower support rods 11 are rotatably installed on the side walls of the two support plates 2, and upper support rods 12 are universally installed on the upper ends of the two lower support rods 11, and the two upper support rods 12 are rotatably connected with auxiliary support rings 13 together. The auxiliary support rings 13 are either elastic rings or belt buckles. The auxiliary support rings 13 are tightly buckled at the thighs to give the support plates 2 a downward separation, strengthen the force load at the knee joints, and the contact parts of the lower support rods 11 and the upper support rods 12 are provided with friction surfaces to increase friction and reduce the deflection flexibility between the upper support rods 12 and the lower support rods 11, so that the auxiliary force between the upper support rods 12 and the lower support rods 11 is more stable.
