Background technology
Clinically for the treatment of the child development dislocation of hip joint, when bilateral femoral anteversion angle difference is larger, it is necessary to
Osteotomy under femoral trochanter is carried out, distal femur is rotated, after being corrected to the top rake of femur, row internal fixation with steel plate.
Clinically common osteotomy method is mainly by the experience of clinician at present, and it has the disadvantage accurately determine osteotomy
Length, osteotomy angle, it is impossible to the accurate center of circle that the Kirschner wire used in osteotomy is inserted to femoral shaft, so as to can not accurately correct
Children femoral top rake, causes potential postoperative Redislocation possibility, caput femoris necrosis risk, early stage hip joint arthritic
Rate increases；Even due to mistake estimation osteotomy angle and length, cause operative failure.In addition, under the femoral trochanter used at present
Osteotomy method and step is cumbersome, is not suitable for the osteotomy of complex deformity.
The content of the invention
For the defect or deficiency of prior art, the invention provides a kind of children femoral Subtrochanteric osteotomy positioning work
Tool.

Determine osteotomy angle mould and determine osteotomy length mould, the main body template is provided with positioning hole.
Optionally, the main body template is provided with the flexure plane that can be fitted with children femoral physiological camber.
Optionally, the determination osteotomy angle is vertically arranged with mould with the determination osteotomy length with mould, and described
Positioning hole is arranged on the junction of the determination osteotomy angle mould and the determination osteotomy length mould.
Optionally, the main body template is that face where a rectangular box, the rectangular box is Cylinder Surface, the rectangle frame
Two vertical edges in body are respectively to determine osteotomy angle mould with determining osteotomy length mould, the determination osteotomy angle
It is located at the circumference of Cylinder Surface with mould, the determination osteotomy length is located at the axial direction of Cylinder Surface with mould.
Optionally, a diameter of 10-14mm of cylinder where the Cylinder Surface, shared by the determination osteotomy angle mould
Circumferential angle is 0~60 °, and the determination osteotomy length die length is 0~40mm.
Optionally, the rectangular box thickness is 1.5mm.
Optionally, a diameter of 1.5~2.5mm of the positioning hole.
Optionally, the determination osteotomy angle is used as rough scale with multiple grooves are offered on mould；It can be provided with thereon

Embodiment
In the child development dislocation of hip joint, femoral anteversion angle is excessive, needs osteotomy under row femoral trochanter to enter in operation
Row is corrected, and existing osteotomy method is mainly to be estimated by the experience of clinician.Therefore, existing osteotomy method can not
Fundamentally realize the security of bone surgery and the accuracy of malformation correction.The design of the present invention may insure under femoral trochanter
The accuracy and security of osteotomy.The angle and length of osteotomy are determined simultaneously, enters in the top rake truly to femur
Accurate correct is gone.
The main body template of the present invention can use arcuate structure, children femoral anatomical structure of fitting so that Kirschner wire can lead to
Navigation passage is crossed directly by the femoral shaft center of circle.
The determination osteotomy angle mould with angle index of the present invention can aid in orthopedist accurately to measure osteotomy angle
Degree；The determination osteotomy length mould of strip length scale can aid in orthopedist accurately to measure osteotomy length, to greatest extent
Ensure the accuracy of osteotomy under femoral trochanter.
The main body template of the present invention is frame structure or is suitable hollow structure, is available for Kirschner wire to pass through.And main body
Stencil design is to be adapted to children femoral physiological camber domes.
Medical stainless steel or other, which may be selected, in the making material of the children femoral Subtrochanteric osteotomy instrument of the present invention to expire
The material of sufficient conformability.
The specific embodiment provided the following is inventor, the present invention can apply but be not limited to the embodiment.
