Abstract

The embodiment of the invention discloses a method for constructing a three-dimensional model of an anatomical structure and a prosthesis thereof. Wherein, the method includes: fitting the anatomical structure to obtain a corresponding outer grid entity; reducing the outer grid entity inwardly to form an inner grid entity; creating a unit cell based on a cube with a preset size; Based on the inner grid entity, generate an inner grid composed of the cells; based on the outer grid entity, generate a corresponding outer grid; connect the outer grid and the inner grid , generating a solid model represented by a grid structure. This method can form a three-dimensional three-dimensional model of the grid structure. The three-dimensional model can well match the lesion area or the three-dimensional shape required for reconstruction and repair.

Description

technical field [0001] The invention relates to the technical field of medical three-dimensional reconstruction, in particular to a method for constructing a three-dimensional model of an anatomical structure and a prosthesis thereof. Background technique [0002] Human organs are very delicate three-dimensional structures used to perform complex functions. It has the characteristics of complex structure and obvious structural specificity. When these specific human organ structures are damaged due to various accidents or accidents and cannot bear the corresponding functions, they need to be repaired and reconstructed through surgery. [0003] For example, when the mandible is defective, it often results in facial deformity and dysfunction, requiring surgical repair and reconstruction to restore the normal function of the human body. [0004] However, the applicant found in the process of realizing the present invention that the existing repair and reconstruction usually ad...
