Description
Technical field
This utility model relates to medical instruments field, specifically a kind of external fixer that is used for the treatment of legg-Perthes disease (femur head necrosis).
Background technology
At present, the legg-Perthes disease etiology unknown is a kind of self-limited disease, and its pathological process comprises osteochondrosis, decalcification, absorption, reparation, new bone formation, rebuilds the femoral head blood supply.Should reduce each stage complication as far as possible in the therapeutic process, make every effort to reach the mortar coupling after the reparation, prevent that an epiphysis and acetabular bone are inconsistent.Femoral head outside epiphysis is outstanding, form subluxation and late period femoral head gross distortion and affecting the treatment, and present two mistaken ideas of treatment existence about this disease: the one, the cause of disease is not bright, do not have conclusive according to confirming that the femoral head intra-osteal pressure increases, the synovial membrane edema is to occur or the change of the secondary of legg-Perthes disease prior to legg-Perthes disease, under fuzzy situation, implement boring decompression, synovectomy operation.The 2nd, over nearly 30 years, the clinician is devoted to always to think that improving femoral head blood transports problem on obstacle, has invented a lot of operation methods, implants as synovial membrane time full excision vascular bundle, and the acceptance rate of performing the operation is 69.23%; Synovial membrane time full excision Dai Ji Pedicle bone piece is implanted, and operation is complicated, and wound is big, and the treatment acceptance rate is low to be 64.2%; Utilize the Chair osteotomy can improve acetabular bone and femoral head containing, change the heavy burden line of force, be that femoral head obtains uniform stress stimulation and reaches farthest biological moulding in acetabular bone, increase in the buttocks simultaneously, the strength of hip abduction muscle groups such as little flesh, acceptance rate is up to 86.3%, these several Therapeutic Method are easy to generate complication, do not reach ideal effect, optimal therapeutic effect is to adopt expectant treatment, and present expectant treatment method adopts the external plaster fixation treatment, the functional rehabilitation of its hip joint, and two lower limb are isometric, the no pain of walking running is so the acceptance rate of the normal development of bone epiphysis can only reach 73.91%.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, a kind of external fixer that does not have operation, no pain, no complication, recovers soon, also can reach a kind of legg-Perthes disease of ideal therapeutic effect to be provided.
The technical scheme that its technical problem that solves this utility model adopts is:
A kind of external fixer that is used for the treatment of legg-Perthes disease, it is characterized in that being provided with fixed cover and fixing pole, fixed cover is provided with the inward turning knob, the inward turning knob is threaded with fixed cover, fixedly the pole two ends are passed the through hole that the inward turning knob is provided with and are connected with fixed cover, fixedly pole and inward turning knob are fixed through bolt, utilize fixedly knee joint of fixed cover, make fixedly the fixed cover at pole two ends keep hip abduction 35 degree-45 degree, keep knee joint to stretch the position, help capital normal reparation.
This utility model can be provided with little fixed cover below fixed cover, the end that fixed cover is relative with little fixed cover is respectively equipped with adjustable plate, adjustable plate is connected through regulating turn-button, regulate turn-button according to the kneed tolerance degree adjustment of patient, making little fixed cover is that the axle center is fixing with knee sprung 5 degree-10 degree positions to regulate turn-button, this geometrical head mortar pressure minimum can effectively prevent patient's heavy burden of standing, and more helps capital normal reparation.
Fixed cover in this utility model and little fixed cover are made up of last cuff and lower ferrule respectively, and last cuff and lower ferrule one side flexibly connect through hinge, also can flexibly connect through twisted axis, can also be hinged through hinge, and opposite side is connected through velcro.
Last cuff in this utility model and lower ferrule inboard and two ends coat through liner, and it is more comfortable that the patient is used.
This utility model can be provided with the boss of threaded blind hole in the last cuff outside, and the inward turning knob is threaded with boss, is beneficial to the rotation of inward turning knob, makes fixing pole can pass through through hole on the inward turning knob smoothly.
This uses novel described adjusting turn-button to be made up of bolt and wing nut, and bolt is threaded with wing nut, helps the fixing of adjustable plate.
The beneficial effects of the utility model are: owing to adopt said structure, make the patient not have slight illness, and no complication, repair ability is strong, the entourage can regulate voluntarily, and therapeutic effect ideal, treatment acceptance rate height are installed voluntarily, have rational in infrastructure, simple to operate, hygiene, recovery rate advantages of higher.
