Description
Technical field
It the utility model is related to medical device field, particularly rectifying for joints such as knee, elbow, hip, ankle, wrist, shoulder joint
Just.More particularly, it is related to being intended to the joint support structure for making up human synovial angle change, particularly ease for use and wound
The modified technique for the property made, including it is intended to mitigate the supporter of arthralgia caused by arthritis.
Background technology
Osteoarthritis is described generally as " wearing " arthritis, because it is the age of height correlation.Osteoarthritis is into
One of disabled most common reason of human body.According to clinical case statistical estimation, China have more than 20,000,000 people have it is this
Disease.
Spontaneous osteoarthritis is generally relevant with aging.With the increase at age, the moisture and protein group of cartilage
Into cartilage degradation.Joint for many years, which is reused, may stimulate cartilage, cause arthralgia and swelling.Finally, cartilage
Start the peeling of degeneration or form small crack.In the case of advanced, there is the femur between the cartilage pad of a total losses
With tibial bone in knee joint, cause joint space to be reduced, cause pain in impacted side knee joint and limit the flowing in joint
Property.The inflammation of cartilage can also promote new bone growth (Spurs) that pain and arthritis periarticular can be caused to be formed.
The case of most of Osteoarthritis is medial chamber regression, and the knee joint of cartilage therein or buffering has significant evil
Change.Then knee becomes uneven, knee is bent outwardly.This is commonly referred to as " out knee " condition." out knee " is (outside knee
Turn over), the commonly referred to as knee joint of valgus deformity, hence it is evident that power aggravates to ache during Human Osteoarthritis walking to compartment on the inside of knee joint
Bitterly, knee is bent, or is stood up.
Worn as offside knee cartilage or cartilage pad, it is abnormal to disease that knee joint can deform aduncate knee joint
One inferior outward appearance of people.This is known as the knee joint of Varus deformity.
In order to improve the quality of life of arthritic, it is necessary to its caused symptom is controlled, purpose mainly reaches
Walked under non-pain state, complete all activities needed for daily life.
It is to wear joint brace that annoying method is commonly used in clinic, and brace is used for the normal line of force for maintaining joint.But no matter adopt
With which kind of therapeutic modality, mechanics problem is involved.Pauciarticular stress must be subtracted, also on the premise of non-functional replacement
It is to say that in complete unstress state hypozygal rehabilitation can be difficult to.It is therefore highly preferred that mechanics therapeutic modality be to subtract pauciarticular load,
The compression of joint junction is especially reduced, the normal activity in joint is not disturbed, optimal therapeutic effect could be obtained.
Due to having the human joint of substantial amounts of multifarious shape and configuration, particularly joint ill or damaging, design
Teacher and manufacturer must find method to adapt to this species diversity, to produce and sell successful product.For varus or turn up
Human Osteoarthritis is, it is necessary to support multiple any angle support patient's Bones and joints, and the angle of setting is adjusted
Locking, in the market has the support that customization is provided for uncommon patient, but such support is fairly expensive, is not many patients
Selection.The gear structure of some past supporting hinges, it is allowed to which positioning is not for optimal guarantor only in predetermined augmental interval
Fine setting compensation needed for shield and therapeutic effect.Many such hinge adjustment, are only supported by removing, make wearer can
Adjustment state into hinge adjusts, and during the wearing of an extension, and wearer can feel to support uncomfortable, or wish to do
Some adjustment hinge angles, to keep required level comfortable and easy to wear, this hinge support, in order to obtain optimal adjustment journey
Degree is, it is necessary to which repeated removal, adjustment and replacing support, until wearer is satisfied with.Expensive and operation inconvenience is not
It is being preferably selected for patient.Therefore we provide a kind of simple in construction, and easy to operate angle compensation device is used for joint support.
