23 Jul Bionic repair method for bone tumors
Abstract
The invention discloses a bionic repair method for bone tumors, and belongs to the computer-aided biomedical engineering, and the method comprises the steps: carrying out segmentation with semantic characteristics on tumor image data of a patient, accurately segmenting and extracting an area corresponding to a target bone tissue, and realizing accurate reconstruction of a segmentation result basedon an envelope and approximation bone surface model three-dimensional reconstruction algorithm; constructing a bionic constraint set and a recovery framework for bone loss caused by bone tumors according to biomedical characteristics of a bone system, realizing accurate recovery of a bone loss form, and designing a constrained free form internal fixation prosthesis based on a bone loss form recovery result; designing an internal bionic porous scaffold structure with good mechanical property and machinability according to the information characteristics of the classified bone area and in combination with a skeleton kinematic mechanical analysis result; and finally, generating an integrated implant prosthesis through fusion, so that a personalized and accurate bone tumor repair system is realized.
