Technical Field

The invention relates to the technical field of surgical nursing equipment, in particular to an adjustable brace for injury of posterior cruciate ligament.

Background

Ligaments join bones, either in a predominantly fibrous tissue, or are attached to the surface of bones or fused with the outer layers of joint capsules to enhance the stability of the joint against injury that can occur when ligaments are pulled beyond their tolerance by violence, causing non-physiological activities; the person with the ligament part damaged and without the joint dislocation tendency is called sprain, the ligament is completely broken, and the bone at the attachment part can be torn off, so that the potential joint dislocation, the half dislocation or even the complete dislocation is formed;

when the ligament is damaged, the staff can support and fix the ligament pulling position of the leg of the patient through the corresponding brace, so that the patient can be better recovered. For example, in the prior art CN108904115A and CN202821768U, a plurality of plate bodies or upper and lower fixing clips are used to realize the positioning fixation of the joint bone parts.

The existing ligament brace has the defects that:

1. the existing brace is integrally fixed, the angle of the leg cannot be better adjusted according to the actual condition of the leg of a patient, so that the brace has more limitations during operation, cannot better meet the rehabilitation treatment of the patient, reduces the practicability of the brace, and particularly needs to frequently adjust the bending degree of the leg of the patient along with the change of the rehabilitation degree of the patient and the trend of a wound healing part so as to keep an effective rehabilitation posture;

2. the existing brace is relatively fixed integrally, the leg can not be adjusted in a telescopic mode according to the actual length of the leg of a patient, so that the patient can hardly achieve a good treatment effect during treatment, and even the brace can not be fixed at an accurate position easily, so that the operation performance of the brace is reduced;

3. the existing brace cannot better achieve the fixing effect when being installed on a patient, so that the patient is easily loosened after installation, the brace is not better positioned at a treatment position, the practicability of the brace is reduced, and meanwhile, the rehabilitation period and the rehabilitation quality of the patient are reduced, so that the further improvement is needed.
