Description
Technical field
This utility model relates to a kind of medical External distraction appliance, belongs to medical instruments field, is applicable in scoliosis orthomorhia.
Background technology
In recent years, the students in middle and primary schools gone to a doctor because of scoliosis have the trend increased, and are that the head of a family and child control oneself and find one high and one low, the back of both shoulders or rib side protuberance mostly, after examination in hospital, are diagnosed as Adolescent Idiopathic Scoliosis Patients.The symptom of child's scoliosis of much going to see a doctor is quite serious, and spinal column has become large serpentine, bends and reaches more than 40 degree, even have impact on cardio-pulmonary function, and the age is relatively bigger than normal, misses optimal treatment chance.Scoliosis is out in the cold, and understanding is not enough, in North America, after child's birth, just have Spine Speciality doctor carries out scoliosis examination to child, and at whole growth stage tracing observation, find that there is scoliosis and person can allow professional rehabilitation doctor treat to a certain extent.Government is provided with the medical institutions of special Rachiocampis correction, carries out rehabilitation and follows up a case by regular visits to needing the child corrected, until reach maturity.And China is to the harm understanding relative deficiency of scoliosis, study delayed, popular science propaganda is short of, and add that China is populous, science census operations is difficult to be in full swing, and causes knowing little about it to the understanding of this disease.The child of scoliosis there will be that neck distortion, both shoulders are not contour, back is uneven, and girl also may occur that udder size is asymmetric, affects attractive in appearance.Thoracic deformity scoliosis is not often the problem of simple rachiocamposis, and thorax also can be out of shape, and extruding thorax can cause pulmonary function reduction, vital capacity reduces, and has a strong impact on important organ and grows.Patient Chang Yin oxygen saturation is anoxia not, and health total quality also can decline.Head pelvic ring traction apparatus was initiated in 1984 by large second Affiliated Hospital professor Ma Jingkun of Shanxi medical courses in general, and from then on this technology is accepted by whole nation colleague.But this technical operation difficulty, easy damaged pelvic cavity viscera and spinal nerves etc., complication is many.On this basis, a kind of medical External distraction appliance of my company's development, easy to operate, satisfactory effect.
Summary of the invention
The purpose of this utility model is: for prior art Problems existing, provides a kind of medical External distraction appliance, better realizes the treatment of scoliosis, reduces the misery of performing the operation and bringing to patient.
To achieve these goals, this utility model provides a kind of medical External distraction appliance, comprises pelvic ring assembly, head ring assemblies, titanium matter bone screw, extends pad assembly, leads to screw component and osseous pin, wherein, described titanium matter bone screw tail end is sharp-pointed, is convenient to implant head skull; Described pelvic ring assembly, comprises pelvic ring, screw, ball faced hexagonal nut, regulating block, adjustment screw and fixture block, described pelvic ring camber, and has screwed hole, and the convenient size regulating pelvic ring assembly, to adapt to different crowd; Described head ring assemblies, comprise head ring, adjustment screw and regulating block, described head ring rear is upturned, reduce the obstruction that patient lies low, this design brings facility to minimal invasive treatment, described head ring distributes multiple screwed hole, convenient from different directions, different parts implants titanium matter bone screw, offer convenience to operation; Described prolongation pad assembly, comprise screw, extend pad and ball faced hexagonal nut composition, the described chute extended on pad facilitates the adjustment of described logical screw component; Described logical screw component, comprises harness cord bar and ball faced hexagonal nut.
Preferably, described regulating block is fixed on described pelvic ring by described adjustment screw, and described regulating block upper and lower surface has netted stricture of vagina, plays anti-skidding effect.
Preferably, described fixture block is connected on described regulating block by described screw, and described screw can move at the chute place on described regulating block, can reach the effect of fine setting, and described prolongation pad assembly alternative uses.
