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
