Medical model based on 3D printing and manufacturing method thereof

Abstract

The invention relates to the field of a medical model, particularly relates to a medical model based on 3D printing and a manufacturing method thereof and aims to provide a model for pre-operative simulation training. The method comprises steps that a three-dimensional digital model of target bones is constructed; a preset number of sub-models of the target bones are extracted; hole repair of a sub-model of each target bone is performed; a three-dimensional digital model of a target soft tissue / organ mold is constructed; according to the sub-models of the repaired target bones and the 3D digital model of the mold, 3D printing is performed to obtain a physical model of the target bones and the mold of the target soft tissue / organ; the physical model of the target soft tissue / organ is produced based on the mold obtained through 3D printing; the physical model of the target bones and the physical model of the target soft tissue / organ are combined to obtain a medical model. The method is advantaged in that the model simulation degree is high, effective pre-operative simulation training for medical staff can be performed;, and the success rate of surgery can be improved.

Description

technical field [0001] The invention relates to the field of medical models, in particular to a 3D printing-based medical model and a manufacturing method thereof. Background technique [0002] Surgery refers to the process of entering the human body or other biological tissues under the operation of surgeons or other professionals, and externally removing lesions, changing structures, or implanting foreign objects (cited from Wikipedia). Including orthopedics and thoracic surgery, which are traumatic, to very delicate neurosurgery, general surgery. All kinds of operations involve important tissues and organs of the human body, such as anastomosis of small arteries, nerves, tendons in orthopedic surgery, duodenum in general surgery, etc. To complete the operation without affecting the normal conditions of other tissues requires surgeons And other professionals have a very comprehensive and three-dimensional grasp of the anatomical structure of the human body, and it is best...
