Abstract

The embodiment of the invention discloses a stereoscopic model construction method of an anatomical structure and a repairing body of the anatomical structure. The method comprises the steps of fitting the anatomical structure to obtain a corresponding outer grid entity; shrinking the outer grid entity inwards to form an inner grid entity; creating cells on the basis of a cube of a preset size; with the inner grid entity as the basis, generating an inner grid composed of the cells; with the outer grid entity as the basis, generating a corresponding outer grid; connecting the outer grid and theinner grid, and generating a stereoscopic model represent by the grid structure. By means of the method, the stereoscopic three-dimensional model of the grid structure can be formed. The stereoscopicmodel can well fit the focus area or the three-dimensional stereoscopic shape required for reconstruction repairing.

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...
