Description
Technical field
This utility model relates to the orthopaedics fixed apparatus, particularly a kind of hip joint external fixator.
Background technology
The major function of hip joint is load-bearing and activity.And the disease of any hip joint is decreased the function that all can influence hip joint, even hip joint is invalid, as femur head necrosis.After fracture of the femoral head and dislocation, acetabular bone fracture compound comminuted, neck of femur tumor cause operations such as damage, femur and tibia fracture, intertrochanteric fracture, need reduce or eliminate the joint power of hip joint, need bending and stretching and interior receipts, abduction functional exercise of early stage hip joint simultaneously; Late period the hip joint infectious disease, be not easy after the operation to carry out internal fixation at intralesional, even can not resist hip joint contraction of muscle on every side or the joint power that spasm produces, even also need long-term bed, cause arthrodesis syndromes such as ankylosis, amyotrophy, osteoporosis collapse of the femoral head, be unfavorable for the recovery of function of joint.The external fixator that uses mostly is the external fixator of femur backbone portion fracture at present, only can fix, and the hip joint after fixing can not carry out activity to temper its function; Or can only carry out the limited flexion and extension of hip joint, can not do abduction and in accept orders for repairs or processing moving.And too heavy, the patient is unsuitable for acceptance.
Summary of the invention
The purpose of this utility model is to propose a kind of hip joint external fixator for addressing the above problem, reach the joint power that can reduce or eliminate hip joint, can make hip joint carry out early stage functional exercise of bending and stretching with interior receipts, abduction again, can fixedly carry out hip joint simultaneously again and merge.
This utility model has proposed a kind of hip joint external fixator to achieve these goals, comprises hipbone fixing head, femoral shaft fixed bar, interior receipts abduction joint, bends and stretches joint, bow, interior receipts abduction slide plate, connecting piece and lock(ing) bolt, needle holder and spicule.Wherein, one end of hipbone fixing head is connected with interior receipts abduction joint, the other end connects described connecting piece, described connecting piece is connected with interior receipts abduction slide plate, in receive the abduction slide plate and bend and stretch the joint and be rigidly connected, bend and stretch the joint and bow is rigidly connected, bow and described in receive the abduction joint and be rigidly connected, constitute a closed frame; Be vertically installed with the needle holder of fixed bone spicule on the hipbone fixing head, bend and stretch the joint femoral shaft fixed bar that is coupling, be fixed with needle holder on the femoral shaft fixed bar.
Be fixed with the ilium fixed bar near interior receipts abduction joint one side on the described hipbone fixing head, have the needle holder of fixed bone spicule on the ilium fixed bar.
The two ends of described hipbone fixing head are fixed on the ilium fixing head by two universal adjustment bars, have the needle holder of fixed bone spicule on the ilium fixing head.
The end that described connecting piece is connected with interior receipts abduction slide plate is an open Baltimore groove, and screw is fixed on the ilium fixing head, and the other end of connecting piece has a mesopore, bend and stretch the joint interior receipts abduction slide plate slides be through at wherein, but and screw fix.
Receiving two ends, abduction joint in described is extensible internal and external casing structure.
Described femoral shaft fixed bar can be epimere, stage casing and hypomere three-stage structure, epimere with bend and stretch the joint and be coupling, epimere and stage casing are the inside and outside sleeve structure, the part that hypomere links to each other with the stage casing is a gimbal structure.
Described gimbal structure extends to a platform of described hypomere.
Effect of the present utility model is to reduce the joint power of femoral head and acetabular bone, can allow hip joint to bend and stretch again and avoid joint accretion, stiff, osteoporosis, collapse of the femoral head with the activity of interior receipts, abduction, fixing hip joint again simultaneously, avoid the fixing and large-scale plaster fixation of intraarticular, reach early ambulation.
