The iliac shape of requirement is made, operating time is reduced, mitigates the damage to patient.
Above-mentioned purpose of the invention is realized by following technical measures:
A kind of operation of Digits reconstruction takes iliac navigation module, including navigation module, and the surrounding of navigation module is uniformly distributed
There are no less than three navigation holes.
The diameter range of the navigation hole is 1mm to 1.2mm.
A kind of Digits reconstruction operation takes the preparation method of iliac navigation module, specific steps are as follows:
The first step acquires target object both hands CT data, carries out three-dimensional reconstruction and obtains virtual both hands threedimensional model；
The data that three-dimensional reconstruction obtains virtual both hands threedimensional model are imported three-dimensional printer, and printed double by second step
Hand mock-up；
Third step measures on both hands mock-up, measures the length and Zhou Jing of defect finger；
4th step draws out the sketch of defect finger part module in 3 D rendering software；
5th step, draws position and the shape of navigation hole on the sketch of defect finger part module, and generates navigation mould
The sketch of block；
The sketch of the sketch of defect finger part module and navigation module is converted to three-dimensional reconstruction software respectively by the 6th step
Data format, and import data to three-dimensional printer prints the mock-up and navigation module of defect finger part module
Mock-up；
Navigation module is fixed on ilium by navigation hole, is cut along navigation module edge by the 7th step when implementing operation
Take iliac；
The mock-up of 8th step, iliac contrast defect's finger part module under cutting carries out finishing reshaping, obtains
To the iliac of suitable form.
Wherein, the second step is specifically and uses three-dimensional reconstruction software Mimics13.01 to carry out three-dimensional reconstruction to obtain void
Quasi- both hands threedimensional model.
The length and Zhou Jing that defect finger is measured in third step, it is real in particular with reference to the healthy side hand of both hands mock-up
Object model estimates Ipsilateral defect part length and Zhou Jing.
In 4th step, the sketch of the defect finger part module is 3 dimensional drawing.
In 5th step, the diameter range 1mm to 1.2mm of the navigation hole.
The printed material used in second step and the 6th step is polylactic acid.
Compared with prior art, the beneficial effects of the present invention are: the purpose of the present invention is to provide a kind of Digits reconstruction hands
Art takes navigation module of iliac and preparation method thereof, can be more according to this navigation module when carrying out cutting iliac
Iliac is more accurately cut fastly, and finishing goes out to meet the iliac shape that reconstruction requires, reduce operating time, mitigate to patient
Damage；In practical operation, it may appear that the case where module shifts is added navigation hole in module edge on this basis, led in art
It crosses Kirschner wire and navigation module is fixed on ilium area, will not shift, cut ilium shape is needed close to operation, refers again to ilium
Block module carries out finishing reshaping, can finally obtain satisfied iliac.
Detailed description of the invention

Specific embodiment
The present invention is described further combined with specific embodiments below, but protection scope of the present invention is not limited to
This.
Embodiment 1:
A kind of operation of Digits reconstruction takes iliac navigation module, including navigation module 1, and the surrounding of navigation module 1 is uniformly divided
No less than three navigation holes 2 are furnished with, and the diameter of the navigation hole 2 is 1mm.
A kind of Digits reconstruction operation takes the preparation method of iliac navigation module, specific steps are as follows:
