Description

Technical Field

[0001] The invention relates to the technical field of orthopedic medical instruments, and in particular to a splint mounting and fastening device and method. Background Art

[0002] A leg fracture refers to a break in the bone structure of the leg, usually caused by a traffic accident, a fall from a height, or a strong impact during physical training. There are different treatment methods depending on the specific situation, such as fixation and bandaging, using splints, plaster and other materials to stabilize the injured part. The ankle of a foot fracture is prone to varying degrees of contusion. When the patient's leg is hoisted and fixed, the patient's ankle is easily subjected to long-term compression, which hinders recovery from work.

[0003] For example, the orthopedic splint installation and fastening device recorded in the patent document with announcement number CN118383922B uses a connecting frame as the installation carrier of the entire device, and the splint mechanism arranged inside it is used to clamp the patient's fracture, wherein the upper splint is used to semi-circularly clamp the upper part of the patient's fracture, and the bendable variable lower splint assembly is used to semi-circularly clamp the lower part of the patient's fracture, and the upper splint can be moved toward the bendable variable lower splint assembly by arranging an adjustment mechanism to form a clamp, and the adjustment mechanism is also connected to a linkage mechanism, through which the bending degree of the bendable variable lower splint assembly can be linked to change, for patients with calf fractures, a certain space can be made for the protruding muscles of their calf to prevent excessive squeezing, reduce the patient's discomfort, and be quick and convenient to operate. This orthopedic splint installation and fastening device does not fix and limit the ankle. When the patient's leg is hoisted for a long time, the ankle cannot be supported, which compresses the blood vessels and easily causes contracture of the plantar fascia, which is not conducive to postoperative recovery.
