Problems solved by technology

[0002] 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’s okay to make larger bone implants, but it’s often rough to make smaller bone implants, which can’t match the implant position

Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] combine figure 1 It can be seen that a manufacturing process of digitally customized bone implants, the specific steps are:

[0013] (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;

[0014] (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;

[0015] (3) Next, use the corresponding material library of the computer...

Abstract

The invention discloses a manufacturing process of a digital customized bone implant. The specific steps are as follows: (1) using computer simulation drawing software to simulate a healthy state diagram when the bone is not damaged, and then combining the damaged bone waiting to be implanted The state diagram simulates the bone shape diagram to be implanted; (2) utilizes computer CAD three-dimensional model making software to draw a complete three-dimensional figure of the bone shape to be implanted; (3) the computer corresponding material library selects and determines the bone implant The material of the implant: then calculate the specific proportion and weight of the polyetheretherketone-hydroxyapatite composite material in the corresponding climate in the corresponding region; (4) use a 3D printer to print out the bone implant. The manufacturing process of the present invention has a faster time for customizing bone implants and higher efficiency, and at the same time, the batching of manufacturing materials is more accurate, so that the quality of the manufactured bone implants is better.

Description

technical field [0001] The invention relates to a manufacturing process of a bone implant, in particular to a manufacturing process of a digitally customized bone implant, belonging to the technical field of orthopedics. Background technique [0002] 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 [0003] 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 qu...
