摘要：
The present invention provides a patient-customized implant designing and manufacturing system for correction of spinal deformity. The system comprises: a first module for extracting a three-dimensional model from a CT image of a spinal patient under control of a control module and selecting a virtual implant model as a plurality of candidate groups on the basis of the extracted three-dimensional model； a second module for performing a fine model modeling in a three-dimensional manner according to spinal curvature of a patient on the basis of a virtual implant model selected by a clinician among the virtual implant models of the candidate groups； a third module for analyzing a three-dimensional implant model optimally designed by the second module by using a finite element scheme under control of the control module, simulating the analyzed three-dimensional implant model, and continuously correcting an error part to analyze a final implant model so that an actual implant has an optimal curve or an optimal curvature； and a fourth module for actually manufacturing a spinal deformity correction implant including a spiral rod and threads customized for an actual spinal patient while having a final virtual implant model analyzed by the third module under control of the control module. According to the present invention, an optimized implant corresponding to a surgical site of each vertebral patient is designed and manufactured to be provided to a surgeon. The present invention significantly reduces a spinal deformity error and a trial-and-error process which a surgeon may be faced by, thereby significantly reducing a time for a spinal correction operation.COPYRIGHT KIPO 2018본 발명은 제어모듈의 기능제어하에 상기 척추환자의 CT 영상에서 삼차원 모델을 추출하고 추출된 삼차원모델을 근거로 가상 임플란트 모델을 여러후보군으로 선정하는 제1 모듈과； 상기 여러 후보군의 가상 임플란트 모델중 임상의가 선택한 가상 임플란트 모델을 기반으로 환자의 척추 만곡에 따라 삼차원으로 정밀 모델화하는 제 2 모듈과； 상기 제2 모듈에 의해 최적화로 설계된 삼차원 임플란트 모델을 제어모듈의 기능제어하에 유한요소법을 이용하여 해석한후 그 해석된 삼차원 임플란트 모델을 시뮬레이션을 하고 에러가 난 부분을 계속 보정하여 실제 임플란
