Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an adjustable fixing device for treating knee joint injuries. Background Art

[0002] The knee joint is one of the most complex joints in the human body and a common site of sports injuries. Injury types include ligament injury, meniscus injury, cartilage injury and fracture, which are common among athletes and the general population. Traditional treatments mainly include drug therapy, physical therapy and surgical treatment. During the treatment process, the knee joint often needs to be fixed to prevent further damage and promote healing. In this process, the use of fixation devices is particularly important. They can not only stabilize the joints and reduce pain, but also accelerate recovery and help patients return to daily activities and sports faster.

[0003] Traditional fixation devices for treating knee injuries usually adopt standard sizes, which are not easy to adapt to the individual differences of the knee joints of different patients, such as leg circumference, joint angle, etc., which may not fit well during use, affecting the fixation effect and comfort. In addition, traditional fixation devices for treating knee injuries are usually one-piece, and the one-piece design may use non-breathable materials. Wearing it for a long time may cause moisture and heat to the skin. In addition, the one-piece fixation device may be complicated to wear and require help from others, which brings inconvenience to the patient's life. It is also troublesome to disassemble it when it needs to be inspected or cleaned.

[0004] Therefore, those skilled in the art provide an adjustable fixation device for treating knee joint injuries to solve the problems raised in the above background technology. Utility Model Content

In addition, through multiple fixing mechanisms, it is ensured that the device can be firmly fixed on the knee joint, which is conducive to the recovery of the injury. First, the patient places the inner side of the knee on the third breathable pad, and then adjusts the first restraint strap according to the thickness of the patient's leg. After the adjustment is completed, the first limiting holes on the first restraining belt fixedly connected to the front and rear ends of the third breathable pad are aligned and overlapped, and the connecting rod is passed through these overlapping limiting holes. Then, the patient pulls the pull rings on both sides of the outer wall of the clamping block to press the connecting rod into the mounting groove inside the clamping block. Since the edge of the limiting block close to the pull ring is fixedly connected to a return spring, and the other side of the return spring is fixedly connected to the inner wall of the sliding groove, when the pull ring is pulled, the third mounting block will enter the sliding groove accordingly, and then the pull ring is released so that the groove fits tightly with the third mounting block, thereby firmly fixing the third breathable pad to the inside of the patient's knee.
