The connecting device comprises an upper connecting branch, a lower connecting branch, an upper support bar, a lower support bar, an adjusting screw and an adjusting nut, wherein the upper end of the upper connecting branch is fixedly connected with the thigh ferrule; the lower end of the lower connecting branch is fixedly connected with the ankle foot orthotic device, and the upper end of the lower connecting branch is hinged to the lower end of the upper connecting branch through a first hinge pin; the upper end of the upper support bar is hinged to the upper connecting branch; the lower end of the lower support bar is hinged to the lower connecting branch, and the upper end of the lower support bar is hinged to the lower end of the upper support bar through a second hinge pin; one end of the adjusting screw is fixedly connected with the second hinge pin, and the other end of the adjusting screw is connected with the first hinge pin in a threaded mode; the adjusting nut is connected with the adjusting screw in a threaded mode. According to the knee-joint orthotic device, structure is simple, production price is cheap, and timely dynamic adjustment in the rehabilitation process of the patient is achieved so as to achieve the purpose of long-term sustainable treatment of knee-joint stiffness and flexion contracture deformation.
Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to a kind of orthopaedic device for knee.
Background technology
Cerebral palsy (cerebral palsy), is called for short cerebral palsy, typically refers to the kentrokiness obstacle causing at non-the carrying out property brain injury in utero being caused by a variety of causes in latter month to being born or encephalodysplasia.Take posture and dystonia, myasthenia, involuntary movement and ataxia etc. as feature, often abnormal with the obstacles such as sensation, cognition, interchange, behavior and Secondary cases skeletal muscle clinically, and can have epilepsy.
In the time of the serious contracture of muscle and joint deformity, can select orthomorphia, and should, as far as possible once completing the orthopedic position of all needs in operation, improve better function so that postoperative.For the infant of the extensive spasm of lower limb muscles and muscular strength normal, can adopt selective posterior rhizotomy.No matter which kind of is performed the operation, and the front and back of implementing in operation, should have the hurt of rehabilitation scheme of standard to match with it.
In rehabilitation, be often used in conjunction with orthosis, limit joint abnormal movement, raising stability to reach, assist to control muscle spasm, keep muscle length, prevent lopsided, the auxiliary objects such as motor function of improving.At present; the mechanical rectification device relating in patients with cerebral palsy rehabilitation; traditional long leg brace or the long leg braces with knee joint limit hinge of adopting more; this series products is only that patient has been played to protection, fixing effect; even if there has been spacing knee joint; also cannot meet the effect of single adjustment, make patient keep for a long time certain position posture, can not meet too high frightened the treatment at heart even of physical consumption that in treatment, the instant effect of adjusting easily causes again patient.
Summary of the invention
Correct after the serious contracture of patients with cerebral palsy muscle and joint deformity for operation, patient needs the fixing also laid up of long-term Gypsum Fibrosum, defect that can not be at will movable.The invention provides a kind of easy to use, can make freely movable orthopaedic device for knee of patient.
Technical scheme of the present invention is achieved in that a kind of orthopaedic device for knee, comprises thigh cuff, ankle-foot orthosis and connecting device, and described connecting device comprises: above connect branch, its upper end and described thigh cuff are affixed; Lower connection branch, its lower end and described ankle-foot orthosis are affixed, upper end by the first swivel pin with described on to be connected the lower end of branch hinged; Support bar, its upper end with described on to be connected branch hinged; Lower support bar, its lower end with described under to be connected branch hinged, upper end is hinged by the lower end of the second swivel pin and described support bar; Adjusting screw(rod), its one end and described the second swivel pin are affixed, and the other end is threaded with described the first swivel pin; Adjusting nut, is threaded with described adjusting screw(rod).
Regulate the relative position angle between thigh cuff and ankle-foot orthosis by adjustable connecting device, thereby realize the dynamic adjustments of patient in rehabilitation process.
The present invention is simple in structure, cheap, has realized patient and has dynamically adjusted that long-term sustainable treatment knee joint is tetanic, the object of Flexor Contracture to reach in the rehabilitation process in good time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is that A in Fig. 1 is to view schematic diagram;
In figure: 1-thigh cuff, 2-ankle-foot orthosis, 3-connecting device, the upper connection of 31-branch, connects branch under 32-, 33-the first swivel pin, 34-support bar, 35-lower support bar, 36-the second swivel pin, 37-adjusting screw(rod), 38-adjusting nut, 4-magnetic sticky buckle band.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Orthopaedic device for knee as depicted in figs. 1 and 2, comprises thigh cuff 1, ankle-foot orthosis 2 and connecting device 3, and described connecting device 3 comprises: above connect branch 31, its upper end and described thigh cuff 1 are affixed; Lower connection branch 32, its lower end and described ankle-foot orthosis 2 are affixed, upper end by the first swivel pin 33 with described on to be connected the lower end of branch 31 hinged; Support bar 34, its upper end with described on to be connected branch 31 hinged; Lower support bar 35, its lower end with described under to be connected branch 32 hinged, upper end by the second swivel pin 36 with described in be that the lower end of support bar 34 is hinged; Adjusting screw(rod) 37, its one end and described the second swivel pin 36 are affixed, and the other end is threaded with described the first swivel pin 33; Adjusting nut 38, is threaded with described adjusting screw(rod) 37.
Described connecting device 3 is two covers, and symmetry is installed on the both sides of described thigh cuff 1 and ankle-foot orthosis 2.
Described thigh cuff 1 and ankle-foot orthosis 2 are U-shaped semi-surrounding structure, are equipped with magnetic sticky buckle band 4.
Air-vent is made and be furnished with to this thigh cuff 1 and ankle-foot orthosis 2 by medical polyethylene or polypropylene, are provided with cotton liner with the inner side of human body contact portion.
Operation principle and the work process of this orthopaedic device for knee are as follows: when use, patient puts on orthopaedic device for knee, bind by magnetic sticky buckle band 4, rotate adjusting nut 38 and can change the distance between the first swivel pin 33 and the second swivel pin 36, thereby in change, connect branch 31 and the lower angle being connected between branch 32, change the angle between thigh cuff 1 and ankle-foot orthosis 2, make patient's knee joint to require to stretch and bending adjusting according to treatment.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
