A waist rehabilitation training device

Abstract

The invention provides a waist rehabilitation training device and a detection method. The device comprises a main frame which is provided with a movable frame unit, a thoracic cavity movable unit, a lower limb exoskeleton, a shape memory alloy drive unit and a detection module unit. The detection method comprises seven steps. Compared with the prior art, the invention has the following advantages:the present waist rehabilitation training equipment is used for fixing the position above the waist of the human body and moving the position below the waist of the human body to realize the rehabilitation training. According to the invention, the waist is seen as a ball joint. The novel lower limb exoskeleton is used to fix the lower part of the body below the waist. The thoracic movable unit realizes the forward flexion and backward extension of the waist and above around the lumbar coronal axis, the lateral bending of the sagittal axis and the rotational motion of the vertical axis. The invention also provides a shape memory alloy actuator, which can realize rapid axial telescopic movement.

Description

technical field [0001] The invention relates to the field of medical rehabilitation training equipment, in particular to a waist rehabilitation training device and a detection method. Background technique [0002] The lumbar spine, also known as the waist, is the largest and most important part of the human spine, connecting the chest and pelvis. The human lumbar joint can realize three degrees of freedom of the spine: flexion and extension around the coronal axis, lateral bending around the sagittal axis, and rotation around the vertical axis. With the aggravation of population aging, the occurrence of accidents and natural disasters and other factors, the number of people with waist motor dysfunction is increasing year by year, especially in various sports and labor, because the waist is subjected to additional force and the load is increased. It is easy to cause various waist diseases due to fatigue. Traditional rehabilitation training mainly relies on the hands-on trai...

AI Technical Summary

Problems solved by technology

The SMA spring of the flexible parallel shape memory alloy driver has no guiding device inside and outside, and the linearity of the axial expansion and contraction of the SMA spring cannot be guaranteed

The telescopic length of the flexible parallel shape memory alloy driver cannot be automatically detected, so it is not conducive to the realization of automatic control

The flexible parallel shape memory alloy driver consists of a common spring and four SMA springs, the four SMA springs are distributed in a square, the common spring is arranged in the middle of the square and parallel to the four SMA springs, so that the radial dimension of the driver becomes smaller. Large, takes up space, is not easy to install, etc.
