Waist training recovering device based on rope traction

Abstract

The invention discloses a waist training recovering device based on rope traction. The waist training recovering device comprises a stander, wherein a lifting device is mounted at the lower end of thestander, a lower-limb fixing device is mounted on the upper surface of the lifting device, symmetric weight-reducing driving mechanisms are mounted on a top beam of the stander, traction ropes are connected to the tail ends of the symmetric weight-reducing driving mechanisms, and a load-bearing waistcoat is connected to the tail ends of the traction ropes; and the weight-reducing driving mechanisms can move on the top beam to adjust the degrees of tightness of the traction ropes, a lap belt winds the periphery the lower end of the load-bearing waistcoat by one cycle, corresponding waist driving mechanisms are connected to four corners of the lap belt through connecting ropes and are glidingly mounted on a transverse rod in the middle of the stander, and the waist is driven to rotate by adjusting the length of the connecting ropes. By utilizing a flexible rope driving manner, the mass of a mechanical structure of a robot system is reduced, the problem that a physical system is poor inflexibility is solved, the training safety, comfort and flexibility of a patient are guaranteed, and secondary injury of the patient is prevented during rehabilitation training.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a waist training and recovery device based on rope traction. Background technique [0002] At present, there are more than 85 million people with disabilities in my country, more than 40.6 million disabled and demented elderly people, and more than 12.42 million people over the age of 40 who have strokes. This huge group makes the demand for rehabilitation continue to expand. Due to the shortage of professional rehabilitation personnel, rehabilitation robots have emerged with the development of the times. [0003] Rehabilitation robot is considered as a "wearable device" in a special environment. It is a medical robot that assists the human body to complete limb movements, realizes the functions of walking for the disabled, rehabilitation treatment, weight-bearing walking, and reducing labor intensity. Most clinical data prove that, under the condition of the...

AI Technical Summary

Problems solved by technology

[0006] Existing rehabilitation training robots mostly use mechanisms such as rigid connecting rods to realize transmission. When performing multi-degree-of-freedom control, the mechanism is very complicated and the mass of the mechanical structure is large.

At the same time, the rigid link mechanism has insufficient adjustment and adaptability to patients of different sizes, and the flexibility of the physical system is relatively poor, which may even cause wrong actions in rehabilitation training, which is very harmful to patients in rehabilitation training. Big safety hazard, unable to flexibly meet the actual needs of rehabilitation training
