Abstract

The embodiment of the invention discloses a method and a device for structural design. The method comprises the steps that a three-dimensional structure model and a contour shape model are built according to three-dimensional structure data and microstructure data of an osteocyte tissue in a preset orthopaedics department database; the three-dimensional structure model and the contour shape model are combined into a bone scaffold model through a preset algorithm, wherein the preset algorithm comprises a Boolean add algorithm; the bone scaffold model is printed through a three-dimensional printer, a bond scaffold model with a microstructure is acquired, and then a biological scaffold with a structure is acquired, thereby realizing that the hole connectivity is good, the hole size is easy to be regulated and controlled, the line diameter and the porosity can be regulated and controlled, and the porosity can reach 95%. A physiological structure, an anatomical structure, the kinematic mechanics, the biomechanics and the bio-fluid mechanics are met. The device is simple in process, convenient to manufacture and short in manufacturing period. A high temperature is avoided, thereby being conducive to introduction and controlled release of bioactive molecules.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of bone structure, and in particular to a method and device for structural design. Background technique [0002] One of the key technologies of tissue engineering is to prepare biomaterials with good biocompatibility and biodegradable absorption properties into multidimensional porous cell scaffolds with specific shapes and connected pore structures. Tissue engineering materials should have good biocompatibility and biodegradable absorption properties. Among them, degradable polymers have the widest application range. As an effective cell scaffold, materials alone are not enough. One of the technical keys of tissue engineering is to make biomaterials into three-dimensional porous scaffolds with specific shape and pore structure. [0003] The pore shapes of tissue engineering porous scaffolds mainly include fibers, porous sponges or foams, and connected tubular structures. Corresp...
