Description

A manufacturing process for digitally customized bone implants

technical field

The invention relates to a manufacturing process of a bone implant, in particular to a manufacturing process of a digitally customized bone implant, and belongs to the technical field of orthopedics.

Background technique

Because bone implants need to be customized, the process is very troublesome. At present, the commonly used method is to use plaster to shape the shape. First, a model is made, and then bone implants are made according to the model. This method has a long production cycle. And it is okay to make larger bone implants, but it is often a bit rough to make smaller bone implants, resulting in a mismatch with the implantation position.

Contents of the invention

In view of the above problems, the present invention provides a manufacturing process for digitally customizing bone implants. The time for customizing bone implants in this manufacturing process is relatively fast and the efficiency is high. Implants are of good quality.

In order to achieve the above-mentioned technical purpose, the present invention adopts a manufacturing process of a digitally customized bone implant, and its specific steps are:

(1) Use computer simulation drawing software to simulate the healthy state diagram of the bone when it is not damaged, and then combine the state diagram of the damaged bone waiting to be implanted to simulate the shape diagram of the bone to be implanted;

(2) Utilize computer CAD three-dimensional modeling software to draw a complete three-dimensional figure of the bone form to be implanted;

(3) The corresponding material library of the computer selects and determines the material of the bone implant: polyetheretherketone-hydroxyapatite composite material, and then calculates the polyetheretherketone-hydroxyapatite composite material in the corresponding climate in the corresponding region with the calculation software. The specific ratio of materials, and calculate the specific weight of the polyetheretherketone-hydroxyapatite composite material used to make this bone implant;

(4) Put the well-proportioned PEEK-hydroxyapatite composite material into the 3D printer, and use the 3D printer to print out this bone implant.

The above-mentioned process abandons the previous cumbersome bone implant production process, greatly simplifies the steps, and improves the production efficiency; because the whole process is assisted by computer-related software, the accuracy of the bone implant is greatly improved; at the same time, a computer-aided system is used to help calculate The specific ratio and specific weight of the polyetheretherketone-hydroxyapatite composite material make the quality of the bone implant made of the polyetheretherketone-hydroxyapatite composite material better.

What Fig. 1 shows is process flow diagram of the present invention;

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Combining with Figure 1, it can be seen that a manufacturing process of digitally customized bone implants, the specific steps are:

(1) First use the computer simulation drawing software to simulate the healthy state diagram of the bone when it is not damaged, and then combine the state diagram of the damaged bone waiting to be implanted to simulate the shape diagram of the bone to be implanted; this step is more critical and directly affects to follow-up steps;

(2) Then use the computer CAD three-dimensional model making software to draw a complete three-dimensional figure of the bone form to be implanted; the steps are based on the step (1), if the step (1) is not done well, The model produced in this step will be deviated or even scrapped;

(3) Next, use the corresponding material library of the computer to select and determine the material of the bone implant: polyetheretherketone-hydroxyapatite composite material. The various indicators of this material are relatively close to or even consistent with human bones, so it is ideal The materials for making bone implants; then use the calculation software to calculate the specific ratio of polyetheretherketone-hydroxyapatite composite materials in the corresponding climate in the corresponding region, and calculate the polyether ether used for making the bone implants. The specific weight of ether ketone-hydroxyapatite composite material; because in different regions and different climates, the proportion of materials will change subtly. Therefore, using a corresponding appropriate proportion in the corresponding climate will help improve the product quality;

(4) Put the well-proportioned PEEK-hydroxyapatite composite material into the 3D printer, and use the 3D printer to print out this bone implant.
