Embodiment 1

[0040] Such as figure 1 Shown, present embodiment provides a kind of preparation method of artificial bone, comprises the following steps:

[0041] S101. Acquire medical image data of a bone injury site of a patient.

[0042] S102. Obtain the 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 grid intersection of the original bone model diagram, and the surface grid intersection point and The embedded free points are connected into 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 model diagram is established through the acquired medical image data of the patient's bone injury site, and then ...

Embodiment 2

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

[0047] S201. Acquire medical image data of a bone injury site of a patient.

[0048] Specifically, CT or MRI is used to perform a thin-slice scan on the injured part of the patient, the thickness of the thin-slice 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 patient's bone injury site according to the medical image data.

[0050] In this embodiment, the CT or MRI image data of the patient's bone injury site is imported into the computer's three-dimensional reconstruction software, and the attenuation of X-rays by substances is reflected according to the gray value of the CT of the human body. For example, the gray value of water is defined as 0, and the gray value of fat is defined as 0. The CT value is -100, and the cortic...

Embodiment 3

[0073] Such as image 3 As shown, this embodiment provides a preparation system for artificial bone, and this embodiment corresponds to the method in Embodiment 1, including:

[0074] The data acquisition module 310 is configured to acquire medical image data of the patient's skeletal injury site.

[0075] The model creation module 320 is used to obtain the original bone model diagram of the patient's skeletal injury site according to the medical image data, perform image processing on the original bone model diagram, and extract the surface grid intersection of the original bone model diagram, the The intersection points of the surface mesh and the embedded free points are connected to form a line, and a microstructure diagram is formed according to the formed line, and a 3D porous model diagram is created.

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

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 difficult problem for orthopedic surgeons and orthopedic surgeons. Every year, a large number of patients have bone defects that are difficult to repair due to various reasons. Artificial bone graft materials have been developed rapidly in recent decades. The existing artificial bone is heavy in quality and poor in biocompatibility, and its overall performance is unsatisfactory. Contents of the invention [0003] The purpose of the present invention is to provide a preparation method and system of artificial bone. The present invention aims to solve the problems of heavy artificial bone and poor biocompatibility at present, and provide a preparation method of individualized and lightweight three-dimensional porous artificial bone. and system. [0004] For rea...
