DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] As shown in FIG. 1, the method for reversed modeling of a biomedical model of the present invention comprises at least the following steps: (a)1 Obtaining the data of a first model; (b)2 Transferring data of the first model by computer into data of a second model which are applied to a rapid prototyping machine; (c)3 Entering the data of the second model into a rapid prototyping machine; (d)4 Laying model materials, coating adhesives and continuing sterilization through the rapid prototyping machine and stacking until a biomedical model is made; wherein sterilization has is done during stacking the said biomedical model, therefore keeping the biomedical model sterile inside is achieved.

[0027] As shown in FIG. 23, the step (a) is obtaining data of a first model, the data of the said first model are obtained by CT (as shown in FIG. 2) or NMR (as shown in FIG. 3), wherein the CT is used for obtaining image data of hard tissue of an organism, for a biomedical model of generating hard tissue, while the NMR is used for obtaining image data of soft tissue of an organism, for a biomedical model of generating soft tissue.

[0028] As shown in FIG. 4, the step (b) is transferring data of the first model by computer into data of a second model, which are applied to a rapid prototyping machine. Since data of the first model obtained by CT or NMR are sectional image data, which can not only easily build a 3D simulated model, but also can be transferred by computer into data of a second model, which are applied to a rapid prototyping machine.

[0029] As shown in FIG. 5, according to computer technique today, one can modify image data by computer, for example, the modify grayscale value, therefore a user can modify data of the first model by computer, to make a biomedical model according to predetermined requirement.

[0030] The step (c) is entering data of the second model into a rapid prototyping machine. A rapid prototyping machine is machine which builds a three dimensional model through layers of stacking. It is conventional art and hence will not be described here.

[0031] As shown in FIG. 610, the step (d) laying model materials (as shown in FIG. 67), coating adhesives (as shown in FIG. 8) and sterilizing (as shown in FIG. 910) repeatedly through a rapid prototyping machine and stacking continually until a biomedical model is made. The action of a rapid prototyping machine will be described by preferred embodiments for demonstration.

[0032] As shown in FIG. 67, action of a rapid prototyping machine for laying model materials is principally laying model materials according to data of the second model in a defined scope. Therefore, various powdery model materials are applicable, wherein biomedical model of macromolecule materials, like PVC (Polyvinyl Chloride), ABS (Acryonitrile-Butadiene-Styrene), PP (Polypropylone) and fluoropolymers, are preferred.

[0033] As shown in FIG. 8, action of a rapid prototyping machine for coating adhesives is coating adhesives according to data of the second model in a predetermined scope laid with model materials, so that the model materials cement together in the predetermined scope. For avoiding intolerance of the organism, biomedical hydrogel (proteinoid) is applied for using as adhesive.

[0034] As shown in FIG. 910, action of a rapid prototyping machine for sterilization is taken at least in a predetermined scope coated with adhesives. Preferably low-temperature plasma is used for sterilization, wherein wave energy stimulates gas, so that ions and molecules collide with each other to produce radicals, thereby the metabolism of micro-organisms is destroyed. Advantages of this kind of sterilization are as following: that sterilization can be done under 50 C.; there are no toxic remnants in environment (Oxygen and water); cycle of sterilization is short and it is feasible to handling medical equipment of low heat resistance/low moisture resistance; due to the action for sterilization, keeping the biomedical model sterile inside is achieved.

[0035] While preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
