Description
Technical field
The utility model is related to a kind of medical treatment device, more particularly to a kind of 3D printing fibula osteotomy device, it is adaptable to need
Fibula cuts osteoplastic surgical field.
Background technology
In recent years, the jaw defect for being caused due to factors such as the problem of growing, traffic accident and facial tumors and deformity
Case is in continuous ascendant trend, and the complexity and difficulty of operation are also continuously increased, and operation risk is improved.For this kind of disease
Oral and Maxillofacial Surgery is the more complicated operation of a class, and the surgeon dentist of current most domestic hospital is implementing this kind of hand
The step of art, is, by the CT captured by patient, observes the region of pathology and rebuilds threedimensional model by specialized medical software
And corresponding operation plan is formulated, but this operation plan is the virtual scheme that doctor designs in medical software, in reality
In operation technique, doctor needs to complete operation completely by the Fibula autograft of the free-hand intercepting patient of experience of oneself, without real
The support of thing, it is difficult to ensure that the length for intercepting fibula meets the requirement of preferable operation plan, the fibula of intercepting is long then doctor
Patient health fibula is wasted, expands wound, intercepting fibula is too short, can affect the enforcement of operation plan, even results in the mistake of operation
Lose, this can allow patient and doctor to bear very big operation risk, so the length for accurately intercepting fibula is to successfully complete jawbone
The premise of prosthesis.
The content of the invention
The purpose of this utility model is to solve the micro-judgment that current fibula bone-culting operation depends on doctor, wind of performing the operation
A kind of big problem in danger, there is provided 3D printing fibula osteotomy device.
The utility model solves the technical scheme that its technical problem adopted：A kind of 3D printing fibula osteotomy device, bag
