Description
Technical field
This utility model is related to a kind of blade plate.
Background technology
Blade plate refers to tabular bone fracture internal fixing device part with holes.Clinically often use cooperatively with bone screw or synthetism silk.It is existing
Some blade plates are all in straight panel shape, and the Osteosynthetic implants metal bone fracture plate as specified in YY0017-2008 standards, in the mark
Quasi- regulation metal bone fracture plate has two kinds of straight type and abnormal shape, but regardless of the metal bone fracture plate of type, blade plate is tabular,
In a plane.As the appearance of healthy bone and bone graft has natural physiological bending, the blade plate of tabular is simultaneously
Can not fit with the perfection of the outer surface of bone, so fixation is insecure.In operation, doctor may according to the profile of connecting portion,
The blade plate of tabular is carried out using hand toolss orthopedic, but the orthopedic precision first is not enough, and being only capable of part improves blade plate pair
The fitting of bone profile.Additionally, the orthopedic of titanium plate can cause titanium distortion of lattice, internal fissure is produced, the connection for weakening titanium plate is strong
Degree.And, repeatedly adjustment and the trial of manual orthopedic needs extends the time of fracture reduction operation.So, patient is on the one hand allowed not relaxed
Clothes, are unfavorable for the recovery of patient bone, while the fixation of metal bone fracture plate is also insecure.
Further, since the elastic modelling quantity of titanium plate is much larger than people's bone, so under stressing conditions, the deformation of blade plate and people's bone
Degree is different, can produce microslip between blade plate and people's bone, and phase mutual friction causes patient pain.
In Chinese Patent Application No. for 201420464816.5 applyings date for 2014.8.18 authorized announcement date it is
2015.1.14 a kind of ankle lower tibiofibula fixation bone fracture plate is disclosed in patent documentation, although which generates beneficial effect, should
What blade plate was contacted with patient bone is also plane, therefore, and cannot be fitted with patient bone completely, equally produce above-mentioned technology and ask
Topic.The main cause of above-mentioned technical problem is caused to be difficult to molding by existing manufacturing technology and fit like a glove with patient bone
Face.

Move, advantageously in the recovery of patient bone, while allowing patient to feel more comfortable.Additionally, need not be manual during surgical
Orthopedic and multiple trial, it is to avoid the mechanical deficiencies of the orthopedic generation of blade plate, it is possible to reduce the quantity that bone screw is fixed, accelerates handss
Art process, reduces patient suffering.
（2）Magnesium alloy blade plate good biocompatibility, Young's moduluss（45GPa）With people's bone（20GPa）It is close, effectively can delay
Solution stress-shielding effect.Additionally, magnesium alloy in human body can gradually be degraded and absorb, second operation can be avoided from taking out, be dropped
The pain of low patient and medical treatment cost.
（3）The surface distributed that blade plate is contacted with patient bone has micropore and depression, and above-mentioned micropore and depression can absorb
With storage body fluid, lubricating layer is formed between blade plate and people's bone, friction is reduced, patient pain is reduced.
（4）According to manufacture method of the present utility model, accurate trouble can be collected using CTA scanning techniques and MRI technique
Person's bone three-dimensional data, the blade plate being fitted according to the three-dimensional data and by the molding of 3D printing energy and patient bone completely, therefore, into
The high precision of type blade plate, low cost, speed are fast.
（5）By vacuum heat, on the one hand adjustment blade plate matrix structure, eliminates the defect of 3D printing, it is ensured that
The mechanical property of blade plate.On the other hand by the unreacted refractory metal granule and bubble of vacuum removing synthetism plate surface, improve synthetism
The surface quality of plate.
