Mechanical structure design of a modularized vertebral detection and therapy instrument

Compared with traditional hands-free massage therapy, vertebral detection and therapy instrument has shown good performance in improving therapeutic effect and safety. At present, foreign vertebral detection and therapy instrument have complete functions. However the cost of the instrument is expensive. Domestic vertebral detection and therapy instruments are cheaper, but the function of detecting muscle hardness is lack. In this paper, the mechanical system of a modularized vertebral detection and therapy instrument is designed. The mechanical part of the instrument is composed of three separable working modules. It has the function of detection and treatment with low cost. The modular design of the instrument solves the problem of overheating during operation, and makes it show some advantages in maintainability, expansibility and other aspects.
