Exoskeleton auxiliary rehabilitation therapy system based on fluid transformation

Abstract

The invention provides an exoskeleton auxiliary rehabilitation therapy system based on fluid transformation. The exoskeleton auxiliary rehabilitation therapy system comprises a tail end continuum mechanism, a driving system and guiding catheters, wherein the tail end continuum mechanism is composed of a base disc, interval discs, alloy wires and a tail end disc, one ends of the alloy wires are fixed with the tail end disc, the alloy wires can freely slide in the base disc and the interval discs, the driving system is composed of an instability resistant module, a fluid transformation mechanism and a movement driving mechanism, the alloy wires are connected with the fluid transformation mechanism through the instability resistant module, and the guiding catheters are used for guiding the other ends of the alloy wires to the driving system from the tail end continuum mechanism. The movement driving mechanism drives the fluid transformation mechanism to drive the alloy wires to perform push-and-pull movement so as to enable the tail end continuum mechanism to be turned and bent. The exoskeleton auxiliary rehabilitation therapy system based on fluid transformation can be self-adaptive to different muscle-bone structures of a patient, avoid damage to the joints of the patient and reduce driving errors caused by regulating hardware.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an exoskeleton-assisted rehabilitation treatment system for assisting joint rehabilitation movement. Background technique [0002] Exoskeletons were originally used to enhance the user's physical functions, such as military weight-bearing or construction work. Another application of it is rehabilitation in the medical field. Stroke or accident can lead to impairment of bodily functions, and severe cases can cause hemiplegia. Repeated assisted limb movement with the help of external force is of great help to the rehabilitation of patients. Existing rehabilitation treatment institutions mainly drive the patient's limbs to move through linkage mechanisms, gear mechanisms, hydraulic mechanisms, and artificial muscles. These kinematic mechanisms all use rigid parts to simulate the motion of joints. The extensive use of rigid parts, on the one hand, increases the volume and weight of...

AI Technical Summary

Problems solved by technology

The extensive use of rigid parts, on the one hand, increases the volume and weight of the system, and increases the cost of manufacturing and use. On the other hand, the use of rigid parts has brought great danger to users due to ergonomic defects Moreover, when the same set of equipment is applied to different patients, it needs to adjust the mechanism to adapt to the patient's musculoskeletal structure
