Method for creating three-dimensional model of headrest main body structure

Abstract

The invention discloses a method for creating a three-dimensional model of a headrest main body structure, which is used for fitting a healthy physiological curve of a human spine, so that the manufactured pillow can correct and treat the neck spine of a cervical spondylosis patient, can also help the spine of a person to keep a natural physiological curve during sleeping, and avoids the problem of cervical vertebra. The method comprises the following main steps: 1, acquiring a local three-dimensional model of a human body; 2, importing the three-dimensional model into 3-matic software, and intercepting a contour curve of a sagittal plane of the human body; 3, intercepting a head and neck matching curve; 4, finding out a pillow position point in the head and neck matching curve; 5, acquiring a pillow position height; 6, determining a headrest bottom plane straight line; 7, obtaining a contour curve of the headrest main body structure; and 8, constructing a three-dimensional model of the headrest main body structure.

Description

technical field [0001] The invention relates to the field of digital medicine and medical equipment, in particular to a method for creating a three-dimensional model of the main structure of a headrest. Background technique [0002] The cervical spine of a healthy person has a certain physiological curve in a natural stress-free state, which also determines that people need soft pillows to maintain the natural state of the head and neck to a certain extent when sleeping, which is also the most comfortable posture for people. [0003] With the improvement of people's quality of life, people pay more and more attention to health preservation and health, and more and more people begin to pursue the most comfortable living conditions and sleep quality. However, for the office workers who sit in front of the computer for a long time and the student party who immerse themselves in reading, more and more patients with cervical spine diseases are caused by improper sitting posture f...

AI Technical Summary

Problems solved by technology

[0005] 1. Traditional pillows cannot be customized to fit the physiological shape of the human head and neck. They can only support the head and neck and have a very limited role in maintaining the normal physiological curve of the cervical spine.

[0006] 2. Although the memory headrests currently on the market are relatively soft, they cannot restore the head and neck of patients suffering from cervical spine deformation to the healthy and natural state before cervical spine deformation, that is, they cannot achieve the effect of corrective treatment and prevention.

[0007] 3. Patent No. CN 110037505A discloses a "multi-partition personalized shape adjustment health care pillow", but the pillow has complicated manufacturing process and high cost, which cannot meet the needs of most people
