Embodiment 1

[0033] The purpose of this embodiment is to provide a kind of rehabilitation protective gear with adjustable shear force, according to Figure 1 to Figure 5 As shown, it includes: a flexible sleeve 1, which is used to cover the thigh and calf on the same side of the human body at the same time and perform flexion and extension actions with them. Therefore, the shape of the flexible sleeve 1 is adapted to the shape of the human leg, and can be Human thighs and calves can also form a certain angle as required to adapt to human movement; during use, the flexible sleeve 1 can be made of sponge, cotton fabric, etc., to provide comfort while protecting the human body.

[0034] The brace assembly 2 is fixed to the outer side of the flexible sleeve 1, and is used to fix the flexible sleeve 1 to the human leg and control the range of motion of the flexible sleeve 1; that is, when the human body moves, the thigh There will be flexion and extension actions between the calf and the lower ...

Embodiment 2

[0040] According to a kind of rehabilitation protective gear with adjustable shear force according to the first embodiment, according to Figure 1 to Figure 4 As shown, the flexible sleeve 1 is provided with an opening 11 corresponding to the knee portion.

[0041] The beneficial effects of the above technical solutions are as follows: the structure of the present invention improves the comfort of the user during use.

Embodiment 3

[0043] According to a kind of rehabilitation protective gear with adjustable shear force according to the second embodiment, according to Figure 1 to Figure 3 As shown, the brace assembly 2 includes two thigh braces 21 symmetrically arranged on the outer side wall of the flexible sleeve 1 , two calf braces 22 symmetrically arranged on the outer side wall of the flexible sleeve 1 . The thigh brace 21 and the calf brace 22 on the same side of the flexible sleeve 1 are hinged, and the two hinge points on the flexible sleeve 1 are symmetrically located on both sides of the opening 11; Both the thigh brace 21 and the calf brace 22 are arranged along the length direction of the flexible sleeve 1 .

[0044] In this embodiment, the thigh brace 21 and the calf brace 22 can be elongated, and the hinged ends of the two are round.

[0045] The beneficial effect of the above technical solution is that it is used to further strengthen the fixation of the flexible sleeve 1 by the brace ass...

Abstract

The invention provides an adjustable anti-shearing rehabilitation protector, which comprises a flexible sleeve used for simultaneously covering thighs and shanks on the same side of a human body and bending and stretching along with the thighs and the shanks; the brace assembly is fixedly connected to the outer side of the flexible sleeve and used for being matched with the flexible sleeve to move along with the legs of the human body; the shank protective cover is connected to the part, corresponding to the shank, of the flexible sleeve through a screw, a gasket is further arranged in front of the position, corresponding to the upper section of the tibia, between the flexible sleeve and the shank protective cover, so that the insertion end of the screw abuts against the gasket through the shank protective cover and is used for controlling the displacement of the tibia towards the front side. The structure has the advantages that the screw is screwed in and extrudes the gasket for limitation, so that the gasket does not fall off in the use process, and meanwhile, the structure has the effect similar to an anterior cruciate ligament.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an adjustable shear-resistant rehabilitation protective gear. Background technique [0002] Anterior cruciate ligament (ACL) rupture is a common sports injury, often causing instability of the knee joint and secondary cartilage damage, and gradually develops into knee osteoarthritis. Current ACL reconstruction techniques cannot effectively prevent joint degeneration. However, the cumulative incidence of knee replacement due to severe osteoarthritis 15 years after ACL reconstruction is more than 7 times that of the general population. A major cause of cartilage damage secondary to ACL injury is abnormal joint shear forces. [0003] Studies have shown that braces can effectively reduce the forward shear force of the knee joint, thereby effectively preventing secondary cartilage degeneration. The traditional brace only has the function of limiting the joint angle and is us...
