PROSTHETIC BONE MODEL, METHOD FOR FORMING A PROSTHETIC BONE, AND SIMULATION SYSTEM FOR MEDICAL USE

摘要

Provided are a prosthetic bone model optimal for use in an osteotomy, a method that can form a prosthetic bone easily and with high precision, and a simulation system for medical use. The simulation system (20) sets p vertices (A(n)) and q vertices (B(m)) on the peripheries of the cut surfaces (a and b) of bone fragments (A and B) formed by cutting and separating a pre-correction bone model, which represents a bone to be corrected, at a prescribed cut location. The simulation system then derives the distances between vertices (A(n) and B(m)). From minimal distance data (LAmin(n, m) and LBmin(n, m)) derived for all vertices (A(n) and B(m)), the maxima are selected as A-side maximal distance data (LAmax(n, m)) and B-side maximal distance data (LBmax(n, m)). The vertices (A(n) and B(m)) that constitute the larger of these are used as start points, and STL construction lines that constitute STL data are formed.
