Description
Technical field
The present invention relates to the contracture deformity apparatus for correcting.
Background technology
Due to reasons such as wound, burn, long-term fixing, infection and ischemic changes, cause necrosis, degeneration, the contracture of muscular tissue, even merge serious blood vessel, nerve, ligament and joint capsule degeneration, simultaneously damaged with serious cicatrix, ulcer, malnutrition and the skin of skin and soft tissue.Unexpectedly can form skin contracture, connective tissue contracture, muscle contracture, nerve arthrogryposis and periarticular soft tissues contracture, cause deformity and the dysfunction in obvious joint.
It is limited that the patella ulnaris arthrogryposis is that the outer or tissue on every side of intraarticular tightens and shorten the range of activity in caused this joint, be common in after skeleton, joint and musculature damage and disease various types of neuroparalysis and long-term bed, long-term wheelchair-bound patient, cause obvious limbs disturbance.It is the common illness of clinical orthopaedics and relevant section office.Understanding based on clinical and scientific research to the arthrogryposis pathological change, give Pathophysiology and pathological changes process that safety, science, feasible intervention can be changed the patella ulnaris arthrogryposis.Patient to clinical rehabilitation gives appliance treatment, the generation that can effectively control or alleviate arthrogryposis.
Mechanism and the mechanics of the design of patella ulnaris arthrogryposis appliance and treatment arthrogryposis, by the Ilizarov technology according to patella ulnaris arthrogryposis deformities, the design and installation external fixator, according to the kneed range of activity of elbow, slowly carry out the soft tissue of tractive contracture, stimulate soft tissue regeneration, make the kneed contracture deformity state of elbow rearrange a relatively normal position, thereby make the tissue of contracture be loosened to greatest extent and extend, continue to increase the kneed range of activity of elbow of contracture.At present both at home and abroad to arthrogryposis, particularly elbow, knee contracture carry out orthopedic correlational study and report very few, give the current common complication that is orthopedics department in clinical middle arthrogryposis, various diseases can cause arthrogryposis, and especially elbow joint, knee joint are common.This sick treatment is thorny, takes the operative treatment wound large, secondary adhesion, poor effect; Functional exercise is difficult to adhere to, and the easy damaged tissue.Therefore, need a kind of effective therapeutic modality, doctor and patient is all acceptant.
According to the Ilizarov biological theory, be tension force-stress rule (law of tension-stress, LTS): the slow drawing-off of biological tissue produces some tension, can histio-irritative regeneration and active growth, its growth pattern is consistent with fetal tissue, is identical cell division.This regeneration is subject to the impact of the supply of blood fortune, stress stimulation frequency and heavy burden.Biological tissue is applied to certain tensile stress, stimulate and keep tissue regeneration and create organizational structure.
Summary of the invention
The object of the invention is to avoid the deficiencies in the prior art that a kind of patella ulnaris arthrogryposis device for correcting abnormality is provided.Application Ilizarov know-why, verify mechanics effectiveness of the present invention and science, and orthosis is applied to clinical trial, observes, analyzes and estimate clinical rehabilitation treatment situation.3 or 4 power of biomechanics are corrected rule, fixedly change treatment in the past into dynamic rectification patella ulnaris arthrogryposis deformity from static state.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of patella ulnaris arthrogryposis device for correcting abnormality, its main feature is to include to be provided with arc fixed plate on the fixed support bar, described fixed support bar is comprised of upper fixed support bar and lower fixed support bar, and hinged by fixed support bar hinge; Upper arc fixed plate and arc lower portable plate one side are hinged, and opposite side connects; Be provided with draw-bar seat on the upper arc fixed plate at two ends, pitch regulator is hinged by active pull rod and draw-bar seat, on the active pull rod of left and right, is respectively equipped with positive/negative thread.
