AI Technical Summary

Technical Problem

Existing lower limb rehabilitation training devices have a simple structure and limited range of motion and frequency, which cannot meet the lower limb extension needs of injured patients, especially the rehabilitation training effect of the ankle joint is not good.

Method used

A lower limb rehabilitation exoskeleton device was designed, including a seat assembly, a first rehabilitation mechanism, and a second rehabilitation mechanism. The first rehabilitation mechanism is used for knee joint training, and the second rehabilitation mechanism is used for ankle pump exercises. The frequency and amplitude of the lifting component are adjusted through a transmission assembly and an electric telescopic rod to adapt to the different range of motion needs of patients during ankle joint rehabilitation.

Benefits of technology

It enables active or passive lower limb range of motion rehabilitation training in a seated position, adapts to different rehabilitation requirements of the ankle joint, improves the rehabilitation effect of the ankle joint, and meets the need for edema reduction in both static and active states of the ankle joint, thus enhancing the rehabilitation effect.

Abstract

This invention provides a lower limb rehabilitation exoskeleton device, relating to the field of medical device technology. It includes: a base plate, and a seat assembly, a first rehabilitation mechanism, and a second rehabilitation mechanism sequentially arranged on the base plate. The second rehabilitation mechanism includes two sets of second electric telescopic rods and a second mounting block fixed to the telescopic end of each second electric telescopic rod. Rotatable lifting components are also provided on the opposing surfaces of the two mounting plates. This lower limb rehabilitation exoskeleton device, through its seat assembly, first rehabilitation mechanism, and second rehabilitation mechanism, enables active or passive range of motion rehabilitation training of the lower limbs in a seated position. Furthermore, the structural characteristics of the second rehabilitation mechanism allow for adjustment of the frequency, amplitude, and height of the lifting components, thereby adapting to different requirements of ankle joint rehabilitation training during the patient's rehabilitation process. It can also meet the patient's need for de-edema reduction in both static and active ankle joint states, further improving the rehabilitation effect.
