3D printing individualized in-vitro bone

Abstract

The invention discloses a 3D printing individualized in-vitro bone. The in-vitro bone is made through the steps that 1, three-dimensional scanning information data of body parts of a patient and structural characteristics of the three-dimensional scanning information data are analyzed; 2, three-dimensional images of the scanned parts of the patients are obtained through computer precision reduction; 3, the three-dimensional images are analyzed and dissected, reverse data of the scanned parts are obtained, and a three-dimensional model of the reverse data is obtained through reestablishment; 4, the three-dimension model is stored or converted as a formatted file ; 5, a three-dimensional model of an in-vitro bone auxiliary device is designed out through a computer; 6, improvement and perfection are conducted through comparison and detection; 7, auxiliary dynamic simulation is conducted through a computer; 8, the simulation result is stored as a formatted file; 9, auxiliary transpose of the 3D printing individualized in-vitro bone is achieved, and a physical model is achieved rapidly; 10, proper surface processing is conducted according to the 3D printing effect, and the use requirement is achieved. According to the 3D printing individualized in-vitro bone, based on individual 3D structure data and characteristics, an auxiliary device for assisting limbs in achieving the mechanical activity function is planed and designed.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a 3D printed individualized extracorporeal bone. Background technique [0002] In recent years, with the development of social economy and population aging, the number of disabled people in our country is increasing, and the number of physically disabled people is huge. more important position. Rehabilitation assistive devices are the use of assistive technology to configure assistive device products for disabled people, which can compensate or replace physical impairments; use engineering methods to supplement the fixed functions of corrective treatment, and maximize the realization of self-care and participation in social activities. Rehabilitation aids are the most basic and effective means to help people with physical dysfunction, especially those with functional decline (such as: fracture, stroke, Parkinson's disease, dysfunction, etc.) to return to society.

If you use inappropriate assistive devices, it will not only be a waste of money, but also seriously cause secondary damage to the body

However, the existing high-end products and inclusive products of assistive devices are few in variety and quantity, and the existing assistive devices are all general-purpose products, which cannot be personalized and individualized.

For example, in response to changes in the situation of the disabled (such as children growing up slowly, or the body slowly recovering after using rehabilitation aids for a period of time, it is required to replace more suitable medical aids at this time), the existing rehabilitation aids are difficult meet needs
