Description
Technical field
The present invention relates to a kind of medical treatment device, print fibula osteotomy device and making thereof and user particularly to a kind of 3D
Method, it is adaptable to need fibula to cut osteoplastic surgical field.
Background technology
In recent years, the jaw defect caused due to factors such as growth promoter problem, vehicle accident and facial tumors and deformity
Case is continuous ascendant trend, and complexity and the difficulty of operation are also continuously increased, and operation risk improves.For this kind of disease
Oral and Maxillofacial Surgery is the operation that a class is more complicated, and the surgeon dentist of current most domestic hospital is implementing this kind of hands
The step of art is, by the CT captured by patient, observes the region of pathological changes and rebuilds threedimensional model by specialized medical software
And formulate corresponding operation plan, but this operation plan is the virtual scheme that doctor designs in medical software, in reality
In operation technique, doctor needs the Fibula autograft relying on the experience free-hand intercepting patient of oneself completely to complete operation, the most real
The support of thing, doctor is it is difficult to ensure that the length intercepting fibula meets the requirement of preferable operation plan, and the fibula of intercepting is long then can
Waste patient health fibula, expands wound, intercepts fibula too short, can affect the enforcement of operation plan, even result in the mistake of operation
Losing, this can allow patient and doctor bear the biggest operation risk, so the length intercepting fibula accurately is to be successfully completed jawbone
The premise of prosthesis.
Summary of the invention
It is an object of the invention to solve current fibula bone-culting operation and depend on the micro-judgment of doctor, operation risk is big
Problem, it is provided that a kind of 3D prints fibula osteotomy device and making and use method thereof.
The technical solution adopted for the present invention to solve the technical problems is: a kind of 3D prints fibula osteotomy device, including edge
The guide plate that fibula direction extends, described guide plate is integral type guide metal, and the medial cross-section of guide plate is in the arc of laminating fibula
Shape, is correspondingly arranged on two semi-ring anchor ears with guide plate two ends, and semi-ring anchor ear and the end of guide plate side fasten, cincture is embraced and is clipped in calf
On bone, guide plate is offered the cutting pilot hole of some strips.The most common 3D prints the fibula main material of osteotomy guide plate
Resin, but operation precision may be affected because heat is deformed when resin material applies cutting in art, in some instances it may even be possible to because of
Cutting or the application of screw and produce fragment or resin is unqualified is retained in the patient, and resin material material is softer, can
Displacement can be produced when performing guide plate task and affect the accuracy of operation.This programme use metal material it can be avoided that more than
Problem, current 3D printing technique has been extended to titanium field, and the 3D meeting guide metal prints requirement, uses 3D to print
Fibula guide metal can the fine problem that must solve this respect, have stable, firm, noresidue, difficult deformation, Ke Yiman
The foot accurate operating requirement of fibula osteotomy guide plate.The osteotomy guide plate being widely used at present is mainly segmentation structure, middle
Using the small-sized link structure of resin material, owing to the hardness of resin material is inadequate, Chang Keneng causes appearance between segmental structure
Skew or the fracture of small-sized attachment structure relatively, this product is metal material, and is global design, without being connected between section with section
Structure, global design further increases the stability of guide plate.
As preferably, the medial wall of described semi-ring anchor ear sets methodical detent projection, the top laminating calf of detent projection
Bone surface.Compared with current resin guide plate, guide metal has also been done suitable structure and has improved by us, adopts at the two ends of guide plate
Use dentation circumferential type structure, application pulling buckle to fix, prevent from cutting process produces slip, displacement, impact cutting location.
As preferably, guide plate is additionally provided with screw hole, screw hole is provided with by tapping screw fixing to guide plate and fibula.?
The mode using metallic self tapping screw fixing on the surface of bone intercepted improves stability.When fibula intercepts, generally carry out segmentation and cut
Taking the mode then piecing together object form, the whole section of fibula the most not intercepted is all to need to use, and needs the calf used
Bone section is typically the most several sections, and the most discontinuous, and middle ware is across the fibula section not used.Owing to needing use
Fibula section and the fibula section not used are spaced, during fixing screw, are fixed on by screw in the fibula section not used, to reduce
To the damage needing the fibula section used.
As preferably, described guide plate and semi-ring anchor ear use 3D printing shaping.
As preferably, described semi-ring anchor ear uses the metal material consistent with guide plate.
A kind of 3D prints the making and use method of fibula osteotomy device, comprises the following steps:
A, jaw defect patient is carried out CT scanning, then CT imports to rebuild in computer maxillofacial bone bone model and fibula
Model；
B, on the maxillofacial bone bone model rebuild, clearly excision position and the cutting route of pathological changes jawbone, exists along cutting route
Computer is simulated cutting to maxillofacial bone bone model；And the pathological changes jawbone model excised is substituted with fibula model, find out length
Degree and the substitute fibula segment model of angle the most adaptive maxillofacial bone bone model otch；
C, using the outer surface of fibula segment model as guide plate and semi-ring anchor ear detent projection top, according to cutting of fibula segment model
Cut offering position and offering angle of pilot hole in mouth length and angle-determining guide plate, determine screw hole location, it is ensured that screw
Hole is positioned at the centre position, cutting hole of both sides, and guide plate and semi-ring anchor ear are carried out three-dimensional modeling, it is thus achieved that guide plate and semi-ring anchor ear mould
Type；
D, the guide plate model using 3D metallic print acquisition fibula location and the semi-ring anchor ear model at two ends；
E, the Calf muscle of patient is cut, the guide plate disinfected is put in otch, and tries to go patch with the inner surface of guide plate
The fibula of combination of syndromes people, when the inner surface of guide plate is all fitted completely with certain section of fibula, i.e. can be identified as the fibula section needing to intercept
Position；
The two ends of f, form semi-ring anchor ear pulling buckle fixed and guide metal encircle and are fixed on fibula, the spiral shell on guide plate
Squeeze into tapping screw in nail and stablize fibula and guide plate further；
Cutting pilot hole in g, guide plate characterizes cutting path during fibula osteotomy, uses and waves according to from the entrance of each cutting pilot hole
Cutting fibula, forms the segmentation structure of fibula；
H, the semi-ring anchor ear at two ends of loosening, take out the tapping screw being fixed on fibula one by one, should after being spliced by the fibula of segmentation
