Abstract

The invention relates to the field of medical models, in particular to a 3D printing-based medical model and a manufacturing method thereof, with the purpose of providing a model for preoperative simulation training. The manufacturing method of the present invention includes the following steps: constructing a three-dimensional digital model of the target bone; extracting a preset number of sub-models of the target bone; repairing holes in each sub-model of the target bone; constructing a three-dimensional digital model of the target soft tissue / organ mold Digital model; 3D printing is performed according to the sub-model of the repaired target bone and the 3D digital model of the mold to obtain the physical model of the target bone and the mold of the target soft tissue / organ; based on the mold obtained by 3D printing, the physical object of the target soft tissue / organ is made Model; the physical model of the target bone is combined with the physical model of the target soft tissue / organ to obtain a medical model. The model produced by the invention has a high degree of simulation, can carry out effective simulation training for medical personnel before operation, and improves the success rate of operation.

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...
