Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, and more specifically, to an adjustable knee joint fixing brace. Background Art

[0002] Knee fixation braces are mainly used to fix and support the knees of injured patients when they have knee joint tissue lesions and fractures, so as to slow down and prevent further lesions and promote the patient's recovery.

[0003] The existing knee joint fixation brace is directly installed at the knee joint position or the brace is placed on the hospital bed to fix the patient's knee joint position. Since the above-mentioned knee joint fixation brace is not convenient to be fixed on the hospital bed, the patient's legs can easily drive the knee joint fixation brace to move, especially just after surgery. The movement of the patient's legs is not conducive to the healing of the wound at the surgical site. In addition, in order to ensure venous blood return just after surgery, the patient's legs need to be fixed in a higher position. Most of the existing knee joints are not convenient for fixing the patient's legs in a higher position and stably fixing the knee joint position. After a certain period of time after the operation, the patient needs to perform super care or postoperative exercise. The existing knee joint fixation brace is not convenient for the patient to exercise to a corresponding degree during the process of fixing the knee joint, which reduces the practicality of its use.
