Coordinate with two alignment pin a, regulating tank a is overlapped with regulating tank b.
Alignment pin c is arranged two, and regulating tank a is located between two alignment pin c.
Second technical solution of the present invention is a kind of production method of DDH osteotomy guide plate, specifically according to following step
It is rapid to implement：
Step 1, using Medical Imaging Technology, acquire the complete CT scan data in patient femur position, build in a computer
Found visual bone pathological model；
Step 2 imports visual skeleton model in 3 d modeling software, calculates anteversion of femoral neck, the neck of patient
Then dry angle calculates the orthopedic rotation angle of osteotomy, interior receipts or valgus angle, the parameter for shortening length；
Top rake is the angle that the line in the central axes and femur of neck of femur between ectocondyle midpoint is formed, and collodiaphyseal angle is
The angle formed between the long axis and the femoral shaft longitudinal axis of neck of femur, by calculating the gap between both angles and normal value,
Need the orthopedic number of degrees are how many to determine respectively；It is that distal bone section is cut 1~2cm to shorten osteotomy, and it is tight can to reduce muscle
Tonicity is resetted with profit.
Step 3, the orthopedic parameter of osteotomy according to calculating, make at bone pathological model osteotomy site according to osteotomy parameter
Osteotomy curved surface；
Osteotomy is normally at below lesser trochanter at 1~2cm, is dug axis direction perpendicular to femur solution, is existed according to this plane
It carries out simulation osteotomy in three-dimensional modeling, after the completion of osteotomy, by distal part of femur using femur section as the center of circle, is pressed along vertical cross-section direction
It is rotated according to the rotation angle precalculated, that is, completes first stage simulation；If you need to carry out varus or osteotomy of turning up to patient,
The second Osteotomy is determined on the basis of then simulation is completed in the first stage；If you need to carry out shortening osteotomy, then by shortening away from
From precalculating in the first Osteotomy.In this way, reaching rotation, the interior operations such as turn up, shorten by osteotomy twice
It is required that.Finally, the position and direction of guide groove in osteotomy oriented module are just can determine according to two Osteotomies；
Step 4, by three-dimensional engineering software at the osteotomy site of affected part skeleton model, the bone in extraction osteotomy region is bent
The model of fixing end and round end is established in face on this basis, and the bone binding face of fixing end and round end is made to pass through and osteotomy
On the completely reliable bone curved surface for being fitted in osteotomy region of the bone feature in region, to ensure the accurate and reliable of positioning, so
Osteotomy guide plate guider base is carried out according to the position and femoral rotation angle of fixing end and round end, interior receipts or valgus angle afterwards
Then the modeling of seat, osteotomy guider, orthopedic template and osteotomy module exports as the required file format of 3D printing；
Step 5 is handled by software and 3D printer is transferred to be printed.
Third technical solution of the present invention is a kind of application method of DDH osteotomy guide plate, specifically according to following step
It is rapid to implement：
Step 1, fixing end and round end are connected by osteotomy module, and dowel hole coordinates with alignment pin a, dowel hole
Coordinate with alignment pin b, fixing end is made to be fixed below osteotomy module with round end, screw passes through the fastening on alignment pin a
After hole connect realization fastening with the nut in nut placing groove a, screw passes through the fastener hole and nut placing groove on alignment pin b
After fastening is realized in nut connection in b, osteotomy guide plate is positioned over patient femur's osteotomy position, and pass through fixing end and round end
Bone binding face osteotomy guide plate is placed on femur, which is the osteotomy site that is pre-designed, and then Kirschner wire is logical
It crosses Kirschner wire location hole b and Kirschner wire location hole a positions osteotomy guide plate, to ensure that guide plate is reliably fixed with patient femur
Position；
Step 2 is adjusted correspondingly osteotomy mould osteotomy guider in the block：
Rotary osteotomy installs osteotomy guider on osteotomy guider pedestal and carries out vertical femur axis osteotomy operation；
Rotation or turns up, shortens osteotomy varus, installed on osteotomy guider pedestal respectively vertical osteotomy guider and
Osteotomy operation is carried out successively with angled osteotomy guider, to realize wedge osteotomy, first carries out osteotomy close to femoral head end, so
Femoral shaft osteotomy is carried out afterwards；
Trip bolt is backed out after the completion of step 3, osteotomy, osteotomy module is changed, carries out the installment work of orthopedic module, will consolidate
Fixed end is connected with round end by orthopedic template, and two dowel hole b and two alignment pin c coordinate, other two positioning pin
Hole b and two alignment pin a coordinate, and regulating tank a is overlapped with regulating tank b, pacified orthopedic module by adjusting the position of round end
It installs into and reaches orthopedic purpose including rotation, varus or turn up, shorten；Finally steel plate is inserted into steel plate guide groove a, respectively
Steel plate and femur are fixed with screw by regulating tank B, V-shaped valley, then remove entire osteotomy module, then be implanted into remaining spiral shell successively
Nail, that is, complete it is orthopedic after fixed step.
The beneficial effects of the invention are as follows：A kind of DDH osteotomy guide plate can improve operation precision, in hand using the osteotomy guide plate
Operating procedure is simplified in art, shortens operating time, and doctor is not necessarily to correct angle by micro-judgment in orthopedic bone-culting operation
Degree, improves accuracy, reduces operation risk.Demand threshold of the operation to doctors experience is reduced simultaneously.A kind of DDH osteotomy

The angle formed between the long axis and the femoral shaft longitudinal axis of neck, by calculating the gap between both angles and normal value, to divide
It Que Ding not need the orthopedic number of degrees are how many；It is that distal bone section is cut 1~2cm to shorten osteotomy, can reduce muscle tone,
It is resetted with profit；
Step 3, the orthopedic parameter of osteotomy according to calculating, osteotomy is made at bone pathological model osteotomy site according to osteotomy parameter
Curved surface；
Osteotomy is normally at below lesser trochanter at 1~2cm, axis direction is dug perpendicular to femur solution, according to this plane in three-dimensional
Simulation osteotomy is carried out in modeling, after the completion of osteotomy, by distal part of femur using femur section as the center of circle, along vertical cross-section direction according to pre-
Precalculated rotation angle is rotated, that is, completes first stage simulation；If you need to carry out varus or osteotomy of turning up to patient, then exist
The second Osteotomy is determined on the basis of first stage simulation completion；It is if you need to carry out shortening osteotomy, then the distance of shortening is pre-
It first calculates in the first Osteotomy, in this way, reach rotation, the interior operations requirement such as turn up, shorten by osteotomy twice,
Finally, the position and direction of guide groove in osteotomy oriented module are just can determine according to two Osteotomies；
Step 4, by three-dimensional engineering software at the osteotomy site of affected part skeleton model, the bone curved surface in extraction osteotomy region,
The model for establishing fixing end (1) and round end (2) on this basis keeps the bone binding face of fixing end (1) and round end (2) logical
Cross on the completely reliable bone curved surface for being fitted in osteotomy region of the bone feature in osteotomy region, with ensure positioning it is accurate and
Reliably, it is then cut according to the position and femoral rotation angle of fixing end (1) and round end (2), interior receipts or valgus angle
The modeling of bone conduction plate guider pedestal (16), osteotomy guider (17), orthopedic template (31) and osteotomy module (18), then exports
For the required file format of 3D printing；
Step 5 is handled by software and 3D printer is transferred to be printed.
