Abstract
The invention discloses an artificial skull-repaired prosthesis manufacturing method. The method is adopted to manufacture an artificial skull-repaired prosthesis with attractive appearance, good fitness and small complications for a skull defect patient. The method is characterized in that patient skull repairing and reforming are achieved through artificial skulls, defects in plastic molding, strength, technology, fitness and the like of normally-used skull-repairing materials are overcome, the manufacturing cycle is greatly shortened, and the side effect of clinic application is obviously 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 of a kind of 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, strong
Degree and hardness, all lower than skull tissue, produce plastic deformation when shock-resistant.And can only lean on manual moulding.Manual moulding to facing
Bed doctor's manual levelling is had relatively high expectations, and titanium alloy is easy-formation not, moulding difficulty, and labor intensity is large, has increased operating time, easily produces warpage and gauffer when moulding, causes prosthesis and defect identical poor, and titanium network edge is sharp easily punctures
Skin 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, with order
Front preparation means is difficult to ensure once to have performed the operation debridement and repairing.And impression, wrinkling, resilience are that multiple spot becomes with edge warping
Distinctive forming defects in shape, impression and the wrinkling good looking appearance that affects skull repairing body, resilience meeting makes dummy size and bone
Window size misfits, and causes dummy to subside or fixing becoming flexible.Edge warping can make dummy and the bone window can not good fit,
Affect 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 trouble
Person'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 d solid modeling tool and the making of skull prosthesis, it 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) in Entity Die, inject artificial skull free-flowing material, mold cramping location, cooling after, the molding of artificial skull free-flowing material, the two is consolidated mould, artificial skull prosthesis;
(3) mould in removal prosthesis outside, i.e. the demoulding, cleaning.
Compared with prior art, technique effect of the present invention is very remarkable:
The present invention utilizes the method for mould molding 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 Pro/E, set up the three-dimensional entity model of skull prosthesis;
(2) according to prosthesis three-dimensional entity model, automatically generate digital control processing NC code, in CNC milling machine, process the mould of defects with skull;
(3) the mobility reconstruction biomaterials of manual manufacture (as HAP bone cement material and aqueous citric acid solution form water and the system of condensing) is inserted in this mould, cooling after, mould, prosthesis are consolidated.
(4) demoulding, the structures such as cleaning prosthesis edge.
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.
