Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an orthopedic retention clamp. Background Art

[0002] The treatment of ankle fractures includes braking, rest, medication, etc., and reliable external fixation treatment is needed to facilitate fracture recovery. Clinically, for patients with milder symptoms, ankle joint fixation braces are mostly used instead of plaster as protective gear to wrap around the feet, as a foot support to assist ankle fixation. At present, the fixation braces used clinically are prefabricated according to the physiological structure of the foot, such as the publication number CN114404895A, which is called an ankle joint trainer, including a sole support, a foot fixing part, an angle adjuster and an ankle fixing part, wherein the foot fixing part is located above the sole support, and the foot fixing part includes a first belt body and a second belt body that can adjust the tightness of the patient's foot, and the ankle fixing part includes a third belt body that can adjust the tightness of the patient's calf. The foot is fixed by passing the end of the belt body around the fixed buckle and then pulling it in the reverse direction to tighten it and fixing the end of the strap by Velcro adhesion.

[0003] The above-mentioned fixation brace adopts the method of wrapping and tightening the part of the instep and the calf located on the front side of the human body by straps, which can ensure that the whole fixation brace will not be easily separated from the foot. However, because the straps can only be pulled and tensioned on both sides of the notch of the outer shell, there is still a certain gap between the front side of the calf and the instep of the human body and the straps. During rehabilitation training, the foot moves, which is bound to cause a large activity gap between the calf and the lining, resulting in relative friction, which is easy to cause a certain pain in the fractured part of the ankle. At the same time, if there is a gap between the inner wall of the fixation brace and the surface wall of the foot, it will become loose as the leg moves, and the bone at the fractured part of the ankle cannot be corrected.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Examples, such as Figure 1 As shown, this embodiment provides an orthopedic retention clamp, including an outer shell 1 and an inner lining 2 detachably mounted on the inner wall of the outer shell 1. Both the outer shell 1 and the inner lining 2 are provided with wearing notches. The inner lining 2 is inserted into the outer shell 1 through the wearing notch of the outer shell 1, and the inner lining 2 is ensured to fit snugly against the inner wall of the outer shell 1, so as to ensure that the wearing opening of the injured person's foot is comfortable and will not affect the sprained part.

[0024] like Figure 2As shown, a strap 12 for restraining the calf and a strap 2 15 for restraining the instep are provided on one side of the wearing gap, and a fixing buckle 11 for the strap 12 and the strap 2 15 to pass through and providing a reversing fulcrum is provided on the other side of the wearing gap, and a fleece surface and a hook surface are provided on the side wall on the opposite side of the wearing gap at the free ends of the strap 12 and the strap 2 15. After the lining 2 is embedded in the shell 1, the patient's foot is worn through the wearing gap, and the instep and the calf can be wrapped around the inner side of the lining 2. The free ends of the strap 12 and the strap 2 15 are passed through the fixing buckle 11 and then tightened in the reverse direction, and the fleece surface and the hook surface are adhered to each other, so as to close the two sides of the wearing gap to ensure compact wearing.

[0025] In this embodiment, in order to ensure that the entire clamp can assist the sprained part of the foot to be fixed with better fit and binding tightness, a transverse adjustment hole 16 is opened on the side wall of the strap 12 facing the wearing gap, and an expansion member can be adjusted at the transverse adjustment hole 16, such as Figure 1 As shown, according to the foot structure of patients with different body shapes, the position of the expansion member is laterally fine-tuned in the lateral adjustment hole 16 to ensure that the expansion member is exactly aligned with the middle position of the foot, thereby ensuring that the expansion is effective.

[0026] Specifically, a protective pad 21 is sewn on one side of the inner side of the lining 2, and the protective pad 21 is provided with a notch at the ankle, such as Figure 4 As shown, the end of the protective pad 21 can be pulled to the other side of the inner side of the lining 2, and then cooperate with the inner wall of the lining to fully wrap the circumferential skin of the foot.

[0027] The expansion member includes an elastic pressing piece 14 and an I-shaped slider 13 slidably engaged in the transverse adjustment hole 16. The I-shaped slider 13 is axially threadedly connected to an adjustment rod 131. The end of the adjustment rod 131 is rotatably connected to the side wall of the elastic pressing piece 14. The elastic pressing piece 14 is attached to the outer wall of the protective pad 21. The upper end of the elastic pressing piece 14 extends to form a first pressing part pressed on the protective pad 21 at the position of the human calf, and the lower end of the elastic pressing piece 14 extends to form a second pressing part pressed on the protective pad 21 at the position of the foot. Figure 3 As shown, the protective pad 21 is wrapped around the foot skin, and the strap 1 12 and the strap 2 15 are passed around the corresponding fixing buckle 11 and then fixed by gluing through the fleece surface and the hook surface, and further expanded by using the expansion member, that is, rotating the adjustment rod 131, and limiting the elastic pressing sheet 14 to keep it aligned with the middle position of the calf and the instep, and then the elastic pressing sheet 14 is adjusted along the axial direction of the adjustment rod 131. According to the tightness requirements, the elastic pressing sheet 14 is pressed on the protective pad 21 at the position of the human calf, and the elastic pressing sheet 14 is pressed on the protective pad 21 at the position of the instep, that is, the entire foot position is fully wrapped and expanded.

[0028] Specific expansion method: the expansion piece expands the inner wall of the strap 12, adjusts the tension of the strap 12, and the two sides of the wearing gap of the outer shell 1 and the inner lining 2 are synchronously closed and enclosed, and the expansion piece is used to further expand the wearing gap, so as to cooperate with the inner wall of the inner lining 2 to form a comprehensive wrapping and fixation at the foot and calf. Then, the gap between the foot and the calf and the inner wall of the lining 2 is reduced, and at the same time, the tightness of the inner wall of the lining 2 wrapping the swollen part of the ankle is adjusted to minimize the gap between the front of the calf and the instep of the human body and the strap, so as to avoid relative friction caused by walking during rehabilitation training, which will cause pain to the fractured part of the ankle. At the same time, it is avoided that the leg becomes loose with the movement, and the fractured part of the ankle cannot be corrected.

[0029] Since the ankle fracture site will swell, when the strap is tightened during fixation, it is easy to cause the swollen ankle fracture site to be too close to the inner wall of the fixation brace, which will compress the swollen site and cause a strong sense of pain. In addition, once the swelling of the swollen site subsides, there will be a gap between the inner wall of the fixation brace and the surface wall of the foot, which will become loose as the leg moves, and the purpose of correcting the bones at the ankle cannot be achieved. Therefore, the expansion strength of the expansion member can be fine-tuned, that is, the pressing strength of the elastic pressing plate 14 can be adjusted by rotating the adjustment rod 131, so as to achieve the tightness of the entire foot wrapping, reduce the pain, and ensure that the wrapping is relatively compact.

[0030] Of course, the above clamp is not only suitable for correction of ankle fractures, but also for leg fractures, ligament sprains, and postoperative protection. It only needs to adjust the expansion strength of the expansion piece to meet the retention requirements of different positions.

[0031] Furthermore, the side walls of the elastic pressing sheet 14 are extended with expansion portions 141, such as Figure 3 As shown, by adding the expansion part 141, the stability of the elastic pressing piece 14 pressed on the protective pad 21 is enhanced to avoid tilting and misalignment. The elastic pressing piece 14 can be made of stainless steel or highly elastic plastic. The elastic pressing piece 14 has a certain elasticity in order to bend and deform itself to press the protective pad 21 at a more curved angle at the intersection of the foot and the calf, thereby improving the retention stability.

[0032] In addition, a plurality of rubber protrusions are provided on the side wall of the protective pad 21 facing the inner side of the liner 2, and an air circulation gap 1 is provided between two adjacent rubber protrusions 23. A corrugated fitting portion 22 is provided on the inner side wall of the liner, and the concave position of the corrugated structure of the fitting portion contacts the skin to form an air circulation gap 2. Figure 4 and Figure 5As shown, the rubber protrusions 23 and the fitting part 22 are made of a rubber material with supporting strength and corresponding softness. After the protective pad 21 is wrapped around the calf and the instep, the rubber protrusions 23 are used to fit the calf and the instep, and the fitting part 22 is used to contact the calf epidermis. While the foot is fixed, air can also be circulated through the air circulation gap 1 and the air circulation gap 2 to avoid inflammation of the affected part caused by long-term wearing. Of course, the position of the fitting part 22 can also be replaced by the rubber protrusions 23 or by opening a mesh.

[0033] Another breathable solution is to open mesh holes on the side wall of the lining 2 and set a corrugated fitting portion 22 on the outer wall of the lining 2. While the lining 2 is used to wrap the foot, an air circulation gap is created between the fitting portion 22 and the inner wall of the outer shell 1, which can also achieve the purpose of ventilation.

[0034] 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.
