Embodiment 1

[0040] Such as figure 1 As shown, this embodiment provides a method for preparing artificial bone, including the following steps:

[0041] S101: Acquire medical image data of the bone injury part of the patient.

[0042] S102: Obtain an original bone model diagram of the patient's bone injury part according to the medical image data, perform image processing on the original bone model diagram, and extract the surface mesh intersection points of the original bone model diagram, and the surface mesh intersection points and The embedded free points are connected to form a line, and a microstructure diagram is formed according to the formed line to create a three-dimensional porous model diagram.

[0043] S103: Prepare a three-dimensional porous artificial bone according to the three-dimensional porous model diagram.

[0044] In this embodiment, a three-dimensional porous artificial bone is created based on the acquired medical image data of the bone injury part of the patient, and then a...

Embodiment 2

[0046] Such as figure 2 As shown, this embodiment provides a method for preparing artificial bone. On the basis of embodiment 1, several steps are added, including:

[0047] S201: Acquire medical image data of the bone injury part of the patient.

[0048] Specifically, a thin layer scan is performed on the injured part of the patient by CT or MRI, the thickness of the thin layer is 0.625 mm, and the format of the medical image data is DICOM3.0.

[0049] S202: Obtain an original bone model diagram of the bone injury part of the patient according to the medical image data.

[0050] In this embodiment, the CT or MRI image data of the patient's bone injury is imported into the computer three-dimensional reconstruction software, and the CT gray value of the human body reflects the attenuation of the substance on the X-ray. For example, the gray value of water is defined as 0, and the gray value of fat The CT value is -100 and the bone cortex density is 2000. Therefore, taking CT skeletal ...

Embodiment 3

[0073] Such as image 3 As shown, this embodiment provides an artificial bone preparation system. This embodiment corresponds to the method in Embodiment 1, and includes:

[0074] The data acquisition module 310 is used to acquire medical image data of the bone injury part of the patient.

[0075] The model creation module 320 is configured to obtain an original bone model diagram of the patient's bone injury site according to the medical image data, perform image processing on the original bone model diagram, and extract the surface mesh intersection points of the original bone model diagram, the The intersection of the surface grid and the embedded free points are connected to form a line, and a microstructure diagram is formed according to the formed line to create a three-dimensional porous model diagram.

[0076] The artificial bone preparation module 330 is used to prepare a three-dimensional porous artificial bone according to the three-dimensional porous model diagram.

Abstract

The invention discloses a method and system for preparing an artificial bone. The method comprises the steps that medical image data of a patient's bone injured part is acquired; an original bone model diagram of the patient's bone injured part is obtained according to the medial image data, image processing is carried out to the original bone model diagram, surface grid intersection points of the original bone model diagram are extracted, the surface grid intersection points and embedded free points are connected into lines, a micro-structural diagram is formed according to the lines, and a three-dimensional porous model diagram is established; and the three-dimensional porous artificial bone is then prepared according to the three-dimensional porous model diagram. The three-dimensional porous model diagram is established according to the acquired medical image data of the patient's bone injured part and then the three-dimensional porous artificial bone is prepared. The artificial bone prepared by the technical scheme has a three-dimensional porous structure; individualization and light-weight features are embodied; and the porous structure is suitable for ingrowth of tissues or bones and has high biocompatibility.

Description

Technical field [0001] The invention relates to the field of bone defect repair, in particular to a method and system for preparing artificial bone. Background technique [0002] Bone defect repair has always been a problem that plagues orthopedics and orthopedic surgeons. Every year, a large number of patients make it difficult to repair bone defects due to various reasons. Artificial bone graft materials have developed rapidly in recent decades, but the existing technology is prepared The artificial bone is of heavy quality and poor biocompatibility, and its comprehensive performance is unsatisfactory. Summary of the invention [0003] The purpose of the present invention is to provide a method and system for preparing artificial bone. The present invention aims to solve the current problems of heavy artificial bone and poor biocompatibility, and to provide a method for preparing an individualized and lightweight three-dimensional porous artificial bone And system. [0004] To a...
