Abstract
The invention discloses a manufacturing method for an artificial skull repair prosthesis by the adoption of the 3D printing technology. The method is used for manufacturing the artificial skull repair prosthesis which is attractive in appearance, good in anastomosis and few in complication for skull-defect patients. The manufacturing method for the artificial skull repair prosthesis has the advantages that according to the manufacturing method, the skull is manually manufactured by the adoption of the 3D printing technology to repair and rebuild the skull of a patient, so that the defects, in molding, strength, process, anastomosis and the like, of common skull repair materials are overcome, the manufacturing cycle is greatly shortened, and the side effects of clinical application are remarkably reduced.
Description
Technical field
The present invention relates to a kind of artificial skull prosthesis preparation method, relate in particular to the making of the moulding reconstruction prosthese of 3D printing defect of skull.
Background technology
Because a variety of causes such as war, traffic accident, weight strike cause many patients because the reasons such as operation or head injury cause defect of skull; after the some patients were state of an illness is steady; defect of skull impact beauty treatment; and defect does not have the protection of skull; there is potential safety hazard, along with growth in the living standard, not only from security standpoint; from quality of life angle, many patients require the reparation of defect of skull.In order to improve looks, the object such as brain safety, incident is exactly skull repairing.Therefore, in the application with regard to this achievement in research, exist huge potential user, market application foreground is wide.
In manufacturing process, mainly contain four kinds of methods both at home and abroad: manual moulding, casting, mould compacting and multi-point forming technique.Medically conventional titanium net is made skull prosthesis now, although titanium net has the advantages that histocompatibility is good, intensity and hardness, all lower than skull tissue, produce plastic deformation when shock-resistant.The sharp easy prick skin of titanium network edge and coming out, causes skin infection.And the existence of metallics, there is mental maladjustment, and affect the imaging examinations such as further MRI (MRI exists magnetic, has drawback for damaged metal reconstruction biomaterials), these shortcomings are all the shortcomings that titanium net skull reparation is difficult to overcome, and have had a strong impact on repairing effect.Casting and mould are compressed on prosthesis and increase qualitatively, but the manufacturing cycle is long, cost high flexibility is poor, is difficult to ensure once to have performed the operation debridement and repairing with current preparation means.And impression, wrinkling, resilience and edge warping are distinctive forming defectses in multi-point forming, impression and the wrinkling good looking appearance that affects skull repairing body, resilience meeting is misfitted dummy size and bone window size, causes dummy to subside or fixing loosening.Edge warping can make dummy and the bone window can not good fit, affects repairing quality.Skull recovery technique, is not only related to vast defect of skull patient health and attractive in appearance, and has a strong impact on patient's quality of life from now on, therefore the research of skull repairing body technology of preparing is had great importance.
Summary of the invention
In view of the existing above-mentioned defect of prior art, the present invention is intended to the preparation defect for existing skull prosthesis, makes improvements from production method and technique, proposes a kind of artificial skull prosthesis preparation method.
Technical solution of the present invention is achieved in that
A kind of artificial skull prosthesis preparation method, comprises that three-dimensional modeling and 3D print the making of skull prosthesis, is characterized in that:
The described three-dimensional entity model course of processing comprises the steps:
(1) according to CT and MRI image technology three-dimensional reconstruction, simulate size and the Surface Parameters of defect of skull, make Entity Die;
(2) adopt 3D printing technique to print artificial skull analog material, produce skull repairing material object;
(3) edge in cleaning prosthesis outside, suits defect of skull position.
Compared with prior art, technique effect of the present invention is very remarkable:
The present invention utilizes the method for 3D printing and making defects with skull, effectively overcome the deficiency of conventional material for repairing skull aspect mechanical performance, performance of technical process and anastomose property, the forming defects such as impression, wrinkling, resilience and edge warping are avoided producing in the course of processing, manufacturing cycle shortens greatly, and the side effect of clinical practice obviously reduces.
Detailed description of the invention
A kind of artificial skull prosthesis preparation method, comprises the steps:
(1) utilize the image technology such as CT or MRI, in 3D sculpting software, set up the threedimensional model of skull prosthesis;
(2), according to prosthesis threedimensional model, adopt 3D printing technique to process the prosthese of defects with skull;
(3) material that prosthese adopts is to have the material that histocompatibility is fabulous (as bone cement) with the mankind.
(4) printed prosthetic material is cleared up and to improve individuation moulding.
The above; it is only preferably detailed description of the invention of the present invention; but protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; be equal to replacement or changed according to the technical scheme of invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
Claims (1)
