A kind of unilateral knee sprung orthotic device that the present invention proposes, comprise large leg splint, shank clamping plate, first connecting rod, second connecting rod, the first runner and the second runner, large leg splint, shank clamping plate are all strapped on thigh, shank by bandage respectively;
Second runner is rotatably installed in shank clamping plate top, and the first runner is arranged between the second runner and shank clamping plate, and the first runner rotates around the second roller centre,
First runner is arranged on large leg splint lower end, large leg splint is provided with the pilot hole arranged along its length, first runner is provided with the first trundle, the second trundle, second runner is provided with the first groove of control first trundle motion, controls the second groove of the second trundle motion, first groove is the straight trough arranged along the second runner radial direction, the arcuate groove that the second groove is is the center of circle with the second roller centre;
First connecting rod is fixedly mounted on the second runner, and first connecting rod is arranged along the radial direction of the second runner, and the other end and second connecting rod one end of first connecting rod are hinged, and the second connecting rod other end is provided with the slide block inserted in pilot hole.
Preferably, the medial wall of large leg splint, shank clamping plate is equipped with lining.
Preferably, large leg splint one end is provided with the spacing hole of multiple installation first runner, and the first runner is arranged on large leg splint by rotating shaft.
Preferably, the first runner and large leg splint one-body molded.
Preferably, the line of centres of the first runner, the second runner and second connecting rod be arranged in parallel.
Preferably, the central point of the second groove and the point coincides of the first runner.
A kind of unilateral knee sprung orthotic device provided in the present invention, second runner is rotatably installed on shank clamping plate, first runner is arranged on large leg splint, first runner is arranged between the second runner and shank clamping plate, first runner is provided with the first trundle, the second trundle, and the second runner is provided with the first groove of control first trundle motion, controls the second groove of the second trundle motion; When knee joint is from 90 ° of flexings, first trundle throws off the first groove, second trundle then with the second groove fit, because the point coincides of the central point of the second groove and the first runner, overlap with the second trundle track, transmission failure, ensure that the phase relation of the first runner and the second runner, makes the cooperation that the first trundle and the first groove at every turn can be correct; The present invention is simple, and more than the flexing of 90 °, thigh splint position can keep fixing, and can not affect wearer upright or squat down, stroke is comparatively large, can meet the demands well, alleviate patient's gonalgia, recover its mobility.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of unilateral knee sprung orthotic device that the present invention proposes.
Detailed description of the invention
As shown in Figure 1, Fig. 1 is the structural representation of a kind of unilateral knee sprung orthotic device that the present invention proposes.
With reference to Fig. 1, a kind of unilateral knee sprung orthotic device that the present invention proposes, comprise large leg splint 1, shank clamping plate 2, first connecting rod 3, second connecting rod 4, first runner 5 and the second runner 6, large leg splint 1, shank clamping plate 2 are all strapped on thigh, shank by bandage respectively; The medial wall of large leg splint 1, shank clamping plate 2 is equipped with lining, is convenient to wearer comfort.
Second runner 6 is rotatably installed in shank clamping plate 2 top, and the first runner 5 is arranged between the second runner 6 and shank clamping plate 2, and the first runner 5 is around the second runner 6 center rotating.First runner 5 is arranged on large leg splint 1 lower end, and in the present embodiment, the first runner 5 is one-body molded with large leg splint 1, improves the bonding strength between the first runner 5 and large leg splint 1.In a particular embodiment, large leg splint 1 one end is provided with the spacing hole of multiple installation first runner 5, and the first runner 5 is arranged on large leg splint 1 by rotating shaft, so that large leg splint 1 is suitable for different wearers.
