Technical Field

[0001] This utility model belongs to the field of medical rehabilitation technology, and more specifically, it relates to an adjustable ankle joint postoperative fixation brace. Background Technology

[0002] In the field of medical rehabilitation, especially in the process of ankle injury or postoperative rehabilitation, patients need assistive devices to ensure that the ankle joint can be exercised moderately within a safe range in order to promote recovery.

[0003] Current fixed braces still have the following shortcomings:

[0004] 1. Different patients have different ankle joint mobility and allowable range of motion. The appropriate range of motion also changes in the early, middle and late stages of rehabilitation. However, existing devices are difficult to accurately adapt to these needs, often resulting in either excessive restriction of the patient's ankle joint movement affecting the recovery effect, or insufficient restriction causing the risk of secondary injury, and failing to provide patients with personalized and dynamic rehabilitation support.

[0005] 2. Patients have different body shapes, foot sizes, and calf lengths. Conventional rehabilitation equipment has a fixed size and cannot adapt to patients of different heights and foot types. When using it, problems such as unstable fixation and poor comfort are easy to occur, causing additional pain to patients. It is also not conducive to long-term wearing and rehabilitation, reducing the compliance and effectiveness of rehabilitation training. Utility Model Content

[0006] To address the aforementioned technical problems, this invention provides an adjustable ankle joint postoperative fixation brace. This addresses the issue that existing devices, as mentioned in the background section, are difficult to precisely adapt to these needs, often resulting in either excessive restriction of the patient's ankle joint movement affecting recovery or insufficient limitation leading to the risk of secondary injury, thus failing to provide personalized and dynamic rehabilitation support for patients.

[0007] The purpose and effect of this utility model, an adjustable ankle joint postoperative fixation brace, are achieved by the following specific technical means:

[0008] An adjustable ankle joint postoperative fixation brace includes: a base plate; the base plate adopts a U-shaped plate structure; an L-shaped plate connecting plate is fixedly installed on one side of the rear end of the base plate, and a through circular groove structure is opened in the middle of the top of the connecting plate, and a through screw hole structure is opened in a semi-circular array on the outer side of the top of the connecting plate; two sets of limiting rods are rotatably installed in the screw holes at the top of the connecting plate through threaded engagement.

[0009] Furthermore, a U-shaped pad structure is attached to the inner side of the base plate with Velcro, and the pad is made of sponge material; a series of binding straps are arranged on the top of the base plate, and Velcro is attached to the binding straps.

[0010] Furthermore, an upper guard plate is rotatably connected to the top rear side of the base plate, and the upper guard plate adopts a U-shaped plate structure; a cylindrical rotating shaft is fixedly connected to one side of the bottom of the upper guard plate, and one end of the rotating shaft passes through the circular through groove at the top of the connecting plate and extends to one side of the connecting plate; a cylindrical connecting rod is fixedly connected to one end of the rotating shaft.

[0011] Furthermore, a set of rectangular groove structure card slots are provided on both sides of the front end of the base plate, and a through screw hole structure is provided on one side of the card slot; a rectangular block structure card block is fixedly connected to the inner side of the card slot, and the outer coin of the card block is in contact with the inner wall of the card slot, and a through screw hole structure is provided on one side of the card block.

[0012] Furthermore, the front sides of the two sets of card blocks are fixedly connected with U-shaped plate extension plates, and both sides of the front wall of the extension plates are provided with a set of rectangular groove structures. One side of the front end of the extension plate is provided with a through-hole structure; a set of screws are rotatably provided in the card slots and the screw holes on one side of the extension plates through threaded engagement.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] When used by medical staff or patients, they can easily insert the two sets of limiting rods into the two sets of screw holes on the top of the connecting plate to precisely limit the distance between the two sets of limiting rods, ensuring that it matches the maximum allowable range of motion of the patient's ankle joint. In this way, as the shaft drives the connecting rods, the limiting rods effectively restrict their swing amplitude, thereby strictly controlling the relative range of motion between the upper plate and the bottom plate, allowing the patient's ankle joint to move within a safe and appropriate range. This not only protects the ankle joint from injury caused by improper movement but also ensures appropriate exercise to promote recovery. Furthermore, the limiting rods can be flexibly adjusted according to the progress of each stage of rehabilitation, greatly improving the scientific nature and precision of rehabilitation training and comprehensively assisting patients in achieving better recovery results.

[0015] It exhibits excellent adaptability to patients of different body types. For patients with small feet, the Velcro pads inside the base plate easily provide a tight, comfortable compression and restraint, preventing the device from loosening or shifting. If a patient is taller or has longer calves and requires an extended base plate, the extension plate can be quickly and securely installed by inserting two sets of clips into the corresponding slots on both sides of the front of the base plate and securing them with screws. This perfectly adapts to the foot and calf sizes of different patients. This highly flexible adjustment method significantly improves patient comfort and the reliability of the fixation, enabling the device to be widely used by various patient groups. It significantly enhances the practicality and versatility of the device, greatly reducing patient pain caused by device discomfort and laying a solid foundation for long-term rehabilitation training.
