Description
Technical field
The utility model is related to the field of medical instrument technology especially to use further to bone surgery fixing device
In the hip joint retractor for the treatment of Femoral Head Necrosis in Children.
Background technology
Childhood inborn depauperation, Hip injury, wound etc., are such as not treated in time, and can cause Femoral Head Necrosis in Children.
Femoral Head Necrosis in Children is also known as scorching femoral head epiphyseal cartilage or coxa plana or Legg-Calve '-Perthes syndromes, multiple
In 2-12 Sui children.This disease starts infant and is goinyalgia-coxarthropathy, and walking is inconvenient or limping, suffer from hip cannot bend and stretch, interior receipts.
Parent is often mistakenly considered to sprain at this time, plus note that delay the course of disease, cause femoral head flatten-" coxa plana ", cause throughout one's life it is residual
Disease.Therefore, this disease early diagnosis early treatment is particularly significant.
In the prior art, for the physilogical characteristics of children, children necrotic femoral head Complicated primary under ambient stress is carried out, is adopted
Hip joint space is carried out with hip joint external fixed support for bone and struts operation, this operation can pull open hip joint space, reduce femoral head
Pressure, reach the low stress environment for suffering from hip, mitigate femoral head at weight loading, keep the abduction inward turning for suffering from hip, increase acetabular bone to femur
The containing of head allows the fibroid reparation at articular cartilage defect, is conducive to that femoral head is moulding, can finally repair children's necrosis
Femoral head.
In the prior art, the hip joint retractor of hip joint external fixed support for bone is hinged external fixator, structure
It is：One straight-bar front end is hinged ball, and ball is placed on pedestal, at entirety in a plane.Since it is planar structure, exist
It and is not easy fixation, retracts the problems such as femoral head and acetabular bone gap are uneven, patient motion is relatively limited.
Utility model content
The purpose of this utility model is to provide for a kind of hip joint retractor, it can overcome in the prior art hip joint lead
Open being not easy fixation, retracting femoral head and acetabular bone gap is uneven, patient motion limitation problem for device.
The purpose of this utility model is achieved through the following technical solutions：
A kind of hip joint retractor, it is characterised in that：Bottom plate supports firm banking by pedestal, and ball is provided on pedestal
Mortar, ball mortar is interior to be arranged steering ball, and steering ball is connected with center bolt, and the center bolt other end is fixed in the middle part of bridge plate, bridge plate two
End is respectively fixed with a bent screw rod.
Further：
The pedestal support is perpendicular to bottom plate.
Angle is 110-140 degree between the pedestal and pedestal support.
The song screw rod, is realized by a bent screws, i.e., angle is 110-140 degree between two straight screw rods of bent screw rod.
The utility model has the beneficial effects that：The utility model is used to treat the outer fixation of children's Femoral Head Necrosis in Children
Frame, in use, upper fixed frame is fixed on by steel nail on hipbone, lower fixed frame is fixed on by steel nail on femur, hip joint
The upper fixed frame of retractor connection and lower fixed frame.It, can be real by the adjusting of the screws such as hip joint retractor center bolt, bent screw rod
The traction of existing hip joint and femur.The utility model protrudes the setting for being inclined base, center bolt, bent screw rod, specific excellent
Putting is：1, make hip joint retractor direction flexibly adjustable, be suitble to Different Individual, fixed convenient for bit selecting.2, fixing glue solid bit selecting,
It is fixed.3, the gap in femoral head joint can effectively be adjusted.4, meet human physiological structure's feature, make between femoral head and acetabular bone
Gap is uniform.5, it is convenient for patient activity.Totally it is more advantageous to new bone formation and Facet remodeling.
In order to make those skilled in the art more fully understand the utility model, and make the above-mentioned mesh of the utility model
, feature and advantage can be more obvious and easy to understand, the utility model is described in further detail with reference to embodiment.
