Description
Technical field
The present invention relates to knee joint therapeutic device technical field, particularly relate to one and exempt from lotus type orthopaedic device for knee.
Background technology
Knee joint is the maximum and the most complicated joint of human body, and its bears a heavy burden many and quantity of motion is large, is the hinge of lower limb exercise.Therefore, its noneffective rate also shelter have first of joint.Wherein, one of disease the most common is exactly osteoarthritis, and it is a kind of chronic joint disease being feature with the degeneration of articular cartilage, wearing and tearing and hyperosteogeny, and joint loads that is long-term and that increase is the main exopathogenic factor that it causes a disease.Meanwhile, knee cartilage wearing and tearing, meniscus injury, fracture of the tibial plateau and tibia node ischemic necrosis are also kneed common diseases, and the generation of these diseases is all relevant to joint loads.And knee joint exempts from lotus orthosis by correcting the line of force, sharing joint loads, being these joint diseases for the treatment of, alleviating patient's gonalgia, recover the important means of its mobility.
Summary of the invention
Based on the technical problem that background technology exists, the present invention proposes one and exempt from lotus type orthopaedic device for knee, structure is simple, easily wear, contribute to maintaining knee joint and stablize, eliminate the load of knee joint muscle ligament, alleviate patient's gonalgia, recover its mobility.
The one that the present invention proposes exempts from lotus type orthopaedic device for knee, comprises large leg splint, shank clamping plate, initiatively runner, driven runner, gear pin and push rod; Large leg splint, shank clamping plate are all strapped on thigh, shank by bandage respectively;
Initiatively runner is provided with the first slotted eye, and the first slotted eye is arc-shaped slot, and the periphery of active runner is provided with an ear, and the central point of the first slotted eye is positioned in ear;
Driven runner is arranged on large leg splint lower end, driven runner is provided with the second slotted eye, the V-shaped groove that the second slotted eye is made up of the arc-shaped slot that two openings are relative, and the junction of two arc-shaped slots adopts circular arc excessive;
Shank clamping plate upper end is provided with the 3rd slotted eye, and the 3rd slotted eye is bar shape trench hole, and the 3rd slotted eye is arranged along the length direction of shank clamping plate;
Driven runner is arranged on the inner side of initiatively runner, shank clamping plate are arranged on the outside of initiatively runner, initiatively runner is with hinged on the upside of shank clamping plate, and the first slotted eye, the second slotted eye, the 3rd slotted eye are connected by gear pin, and gear pin is the multidiameter that mid diameter large two ends diameter is little; Push rod one end and ear hinged, the push rod other end and the thigh holder be enclosed within large leg splint are hinged.
Preferably, driven runner and large leg splint one-body molded.
Preferably, large leg splint is provided with the 4th slotted eye installing driven runner; Driven runner is connected with the 4th slotted eye by locking device.
Preferably, the medial wall of large leg splint, shank clamping plate is equipped with lining.
Preferably, gear pin adopts stainless steel to make.
Preferably, the central point of the first slotted eye overlaps with ear and push rod pin joint.
The one provided in the present invention exempts from lotus type orthopaedic device for knee, thigh is power source, drive large leg splint and rotate with the active runner of its consolidation, driven sheave is driven to rotate backward by gear pin, and under the effect of push rod, promoting large leg splint and thigh holder upwards rectilinear motion, push rod acts on thigh again, forms the power transmittance process closed, also motion is become the rectilinear movement of stroke extension simultaneously from rotation, realize knee joint and exempt to carry.Kneed flexion and extension is become the rectilinear motion of stroke extension by the present invention, can obtain larger displacement in less planar dimension; Be less than 90 ° of operation intervals bent and stretched in knee joint to play a role, then do not produce the stroke of tractive when being greater than 90 °, reducing the impact that lower limb wide-angle is bent and stretched; When knee joint is upright, push rod and joint of the lower extremity axis being parallel, now orthosis is in the stable position at mechanics dead point, contributes to maintaining knee joint and stablizes, eliminate the load of knee joint muscle ligament, alleviate patient's gonalgia, recover its mobility.
