Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
This utility model provides a kind of brace of auxiliary posterior cruciate ligament injuries rehabilitation, as shown in Figure 1, comprises the thigh fixing head 1, oval rotating disk 2, the shank fixing head 3 that are connected successively; As shown in Figure 4, the other end that thigh fixing head 1 comprises interconnective first fixing head 4, second fixing head 5, the 3rd fixing head 6, second fixing head 5 and the 3rd fixing head 6 is parallel to each other; First fixing head 4 is provided with the first fixing hole 7, passes for nylon stick bracelet, between the second fixing head 5 and the 3rd fixing head 6, be provided with gear 8, the second fixing head 5 and the 3rd fixing head 6 are provided with axle center sliding tray 9 on the right of gear 8; As shown in Figure 5, shank fixing head 3 comprises the 4th fixing head 10,4th fixing head 10 is provided with the second fixing hole 11, pass for nylon stick bracelet, oval rotating disk 2 and the 4th fixing head 10 are fixed on the second fixing head 5 and the 3rd fixing head 6 through the second fixing head 5, oval rotating disk 2, the 4th fixing head 10 and the 3rd fixing head 6 by the first fixed axis 14 successively; Gear 8 and oval rotating disk 2 are connected with a joggle.
First fixing hole 7 is along the length of the first fixing head 4 to setting, and the first fixing hole 7 is strip.
Second fixing head 5 and the 3rd fixing head 6 are provided with the 4th fixing hole 13, second fixed axis 15 by the 4th fixing hole 13, gear 8 is fixed between the second fixing head 5 and the 3rd fixing head 6.
Second fixing hole 11 is along the length of the 4th fixing head 10 to setting, and the second fixing hole 11 is strip.The brace of auxiliary posterior cruciate ligament injuries rehabilitation is fixed on knee joint place through the first fixing hole 7 and the second fixing hole 11 by nylon stick bracelet.
Axle center sliding tray 9 is strip, and oval rotating disk 2 is arranged between the second fixing head 5 and the 3rd fixing head 6 by axle center sliding tray 9 and the first fixed axis 14; 4th fixing head 10 is provided with the 3rd fixing hole 12,4th fixing head 10 is arranged between the second fixing head 5 and the 3rd fixing head 6 by axle center sliding tray 9, first fixed axis 14 and the 3rd fixing hole 12, second fixed axis 15 is outside equipped with scale adjustment disk 16 at the second fixing head 5, because the flexion angle of Normal Knee is 0 °-135 °, and rehabilitation course be one incremental, bend and stretch the process that angle is increasing, progressively can arrange according to rehabilitation programme, adjustment scale adjustment disk 16 increases activity point of view.
This brace adopts aluminium alloy.
In use, the brace of auxiliary posterior cruciate ligament injuries rehabilitation is fixed on knee joint place through the first fixing hole 7 and the second fixing hole 11 by nylon stick bracelet, the oval rotating disk 2 that knee joint place adopts non-coaxial to rotate, knee joint can be made when carrying out flexion-extension motion along with the increase of angle produces one gradually by the power of tibia driven forward, move after restriction tibia, avoid posterior cruciate ligament that is that damage or that rebuild in flexion and extension, be subject to tension force effect, for the posterior cruciate ligament of damage or the bone tendon healing of ligament provide a good environment, also be of value to patient hinder after or early postoperation carry out suffering limb functional exercise, avoid joint stiffness, the complication such as the deep vein thrombosis of lower extremity that prevention patient long-term bed causes.As shown in Figure 5, when leg knee joint is stretched, thigh fixing head 1 and shank fixing head 3 on same straight line, in flexing process, because the point of contact of circular gear is moved to major axis gradually by the minor axis of ellipse in oval rotating disk and thigh fixing head, the focus of oval rotating disk is pushed, slide in the axle center sliding tray of thigh fixing head, sliding distance is the difference of transverse and minor axis, promotes shank fixing head forward slip gradually, tibia is pushed away forward, moves after restriction tibia.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but this utility model is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, many variations can also be made to it.
