Embodiment
The invention will be further described with the following Examples.
Embodiment 1.
A kind of preparation method of the moulding bone piece model of finger phalanges bone thickening, comprises the following steps：
(1) destination object both hands CT data are gathered, three-dimensional reconstruction is carried out and obtains virtual both hands bone threedimensional model；
(2) reconstruction model data import three-dimensional printer, print both hands bone mock-up；
(3) strong side phalanges form profile is drawn, cuts out and obtains normal phalanges profile；
(4) Ipsilateral phalanges form is contrasted, draws and cuts out and obtain defect part phalanges size and form；
(5) measurement defect phalangeal section major diameter and minor axis, and record numerical value；
(6) polishing of bone piece model cutting is carried out according to defect phalangeal section measured value and form to obtain repairing bone piece mould
Close to defect phalangeal section form in type, the repairing bone piece model forms of acquisition.
Specifically, the preparation method of the above-mentioned moulding bone piece model of finger phalanges bone thickening, utilizes 3D printing technique system
Standby normal phalanges and Ipsilateral phalanges appearance model, obtain repairing the form of bone piece model using morphological differences.
Wherein, step (1) is specifically and carries out three-dimensional reconstruction using three-dimensional reconstruction software Mimics13.01 to obtain virtual both hands
Bone threedimensional model.
Wherein, step (2) is specifically that Three-dimension Reconstruction Model is imported into three-dimensional printer, and prints bone mock-up.
Wherein, step (3) is specifically to draw strong side phalanges form profile, cuts out and obtains normal phalanges profile.
Wherein, step (4) is specifically contrast Ipsilateral phalanges form, draws and cuts out and obtains defect part phalanges size shape
State.The 3D printing material that step (4) is used is PLA.
Wherein, step (5) is specifically measurement defect phalangeal section major diameter and minor axis, and records numerical value.
Moulding using the method progress finger phalanges bone thickening of the present invention, the repairing bone piece model forms obtained are with lacking
Damage phalangeal section highly to approach, can preferably realize for the moulding form reparation of phalanges thickening.
The method of the present invention coordinates clinic so to use, and obtains after repairing bone piece model, conjunction is cut with reference to this model
Needed for suitable reparation during bone piece, bone piece needed for reparation, the repairing bone piece form and defect obtained faster can be more accurately cut
Phalangeal section is highly approached, and can preferably be realized for the moulding form reparation of phalanges thickening.Then, the reparation bone piece of acquisition is existed
Pre- repair is realized on Ipsilateral phalanges model；Bone piece will will be repaired again to apply and clinical operation and postoperative perspective situation.
Thumb Digits reconstruction operation especially transplanting thumb reconstructed by second toe reconstruction thumb finger, thumb reconstructed by second toe is more normal on anatomic form
Therefore thumb is partially thin to cause postoperative reconstruction thumb finger form, with normal thumb poor appearance away from larger, to be adopted in addition closer to toes
The method for wrapping floating bone block transplanting reconstruction thumb finger with Hallux first valve finds that some patients have bone piece and withered through clinical Follow-up After
Contracting phenomenon, causes form to there is difference with desired morphology.For the appearance of such situation, clinically often need to carry out finger phalanges
Thickening plastic operation is to reach the target for recovering to be close with normal thumb finger form.
When carrying out phalanges thickening plastic operation, it is necessary to carry out repairing cutting for bone piece, traditional operation is based on patient's experience
Carry out repairing bone piece and cut, lack objective reference frame, operation short time consumption long, fluoroscopy during operation often, to patient and doctor
The injury of business personnel is larger.
, can be faster more accurate according to the method when bone piece needed for needing progress to cut reparation by the method for the present invention
True cuts bone piece needed for reparation, and the repairing bone piece form obtained is highly close with defect phalangeal section, can preferably realize pair
In the moulding form reparation of phalanges thickening.
Embodiment 2.
By taking destination object after a finger reconstruction as an example, this method is illustrated.

Body is to carry out three-dimensional reconstruction using three-dimensional reconstruction software Mimics 13.01 to obtain both hands threedimensional model, as shown in Figure 1.
(2) both hands mock-up 20 is printed, plasma ion disinfection is standby, as shown in Figure 2.The 3D printing material specifically used
For PLA, the print attribution of 3D printer is set, high-precision printing state is adjusted to, printing precision is under specific such a state
0.2mm, adjusts the printing plane of 3D printer, the shower nozzle of 3D printer is smoothly led to just to the distance of printing plane
Cross the A4 paper of a folding.Then, model modes of emplacement is adjusted, it is maximized with printing the contact area of plane, now beats
Stamp type obtains most stable position, to improve the success rate of printing and reduce the formation of print carriage, so just improves 3D and beats
The manufacture efficiency of print machine and 3D printing material is saved.Finally, the temperature for setting 3D printer shower nozzle is 220 degree, starts 3D
Print routine, shower nozzle is heated to after predetermined temperature, just starts successively to print accumulation, both hands bony segment needed for finally producing
Model, as shown in Figure 2.
(3) as shown in figure 3, drawing strong side phalanges form profile, cut out and obtain normal phalanges profile.Wherein, at this
In example, use edge of the skin marking pen vertically with cystosepiment along strong side phalanges model and painted on cystosepiment
System, and trim the profile for obtaining strong side phalanges.
(4) as shown in figure 4, contrasting Ipsilateral phalanges form on the basis of Fig. 3, draw and cut out and obtain defect part phalanges
Size and form.
(5) as shown in figure 5, measuring defect phalangeal section major diameter and minor axis, and numerical value is recorded.
(6) repaiied as shown in fig. 6, carrying out the polishing of bone piece model cutting according to defect phalangeal section measured value and form
Close to defect phalangeal section form in Psoralen block models, the repairing bone piece model forms of acquisition.With reference to repairing bone piece model,
Cut after transplanting bone piece, carrying out bone piece cutting according to defect phalangeal section measured value and form polishes, and obtains and defect phalanges
The close repairing bone piece of portion forms.
(7) repaired in advance as shown in fig. 7, carrying out reparation bone piece on Ipsilateral phalanges model.
(8) as shown in figure 8, the reparation bone piece of design is applied into clinical operation, and postoperative perspective is carried out, observation Ipsilateral refers to
Bones morphology repairs situation.
The method of the present invention, when needing progress reparation bone piece to cut, faster can more accurately be obtained according to the method
Bone piece is repaired, operating time is reduced, the damage to patient is reduced.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention rather than the present invention is protected
The limitation of scope, although being explained in detail with reference to preferred embodiment to the present invention, one of ordinary skill in the art should manage
Solution, technical scheme can be modified or equivalent substitution, without departing from technical solution of the present invention essence and
