Description
Technical field
The present invention relates to biomedical engineering extracorporeal components technical fields, especially prevent exposed Auricular framework modeling side
Method, manufacturing method and corresponding Auricular framework.
Background technique
Currently, the disease incidence of microtia is in significant ascendant trend, regular complex, life to patient in worldwide
Haircut is educated, and the even society, family of patient may cause heavy burden and economic pressures.Auricle reconstruction operation is generally divided into III
Phase, there are many operation methods, are required to selection suitable Auricular framework and skin covering tissue.The general multiselect of Auricular framework material
With self costal cartilage or Medpor ear supporter, also using by both material combination brackets, but it is postoperative in auricle reconstruction, often
With generation this complication of frameworks exposure.It is more difficult for the processing of frameworks exposure, it is sometimes desirable to take the bracket being implanted into
Out, operative failure is eventually led to.Clinical medicine proves, sends out the phase well in postoperative March to be exposed, and no matter which kind of operation side used
How easy formula row Postauricular flap, the outer upper limb of helix, anthelix lower edge, the reconstruction pressure points such as ear and residual ear junction, point of tension, skin wrinkle be
The reason of position infected is easy to happen frameworks exposure phenomenon, causes be mainly rough by rack surface, bracket and skin
Overtension, local skin flap's blood fortune, postoperative vacuum suction iso-stress concentration problem cause between skin.Therefore, a kind of prevention is needed
Modeling method, manufacturing method and the Auricular framework of exposed Auricular framework obtain corresponding data by sunykatuib analysis, thus
Directive function is played in operation or research.

Step 2 carries out grid differentiation to the contour feature data obtained in step 1；
Step 3, by grid obtained in step 2 differentiation after data combination timbering material characterisitic parameter and skin properties
Parameter carries out finite element stress analysis；
Step 4, the finite element stress analysis according to step 3 as a result, to the 3rd day after the bracket, the 3rd is built
The stress concentration portion position of the bracket carries out sunykatuib analysis at a month, the 6th month, determines the position that ulceration easily occurs；
Step 5 is compared with clinical case data, and the structurally corresponding easy generation ulceration position of Auricular framework is carried out
It is exposed to prevent the bracket stress concentration for adjustment and engraving.
Further, contour feature data described in the step 1 are the point cloud data obtained by laser scanner.
Further, the grid differentiation carried out in the step 2 uses the grid of 0.3mm~0.5mm.
