Two-degree-of-freedom upper limb rehabilitation training robot system

Abstract

The invention discloses a two-degree-of-freedom upper limb rehabilitation training robot system which comprises a rehabilitation robot mechanism, a mechanism supporting table and an elbow supporting frame, wherein the rehabilitation robot mechanism comprises a mechanism outer frame, a two-parallel-connection-rod mechanism capable of realizing motion with two degrees-of-freedom, a first driving mechanism for driving the two-parallel-connection-rod mechanism to do motion in the x direction and a second driving mechanism for driving the two-parallel-connection-rod mechanism to do motion in the y direction; the elbow supporting frame comprises a base for fixing, a supporting shaft fixed on the base, a rotating shaft arranged on the supporting shaft in a rotatable manner, a guide rail which is fixed on the rotating shaft and is provided with a groove, and a sliding block for freely sliding along the groove of the guide rail. The two-degree-of-freedom upper limb rehabilitation training robot system is simple in structure and moves flexibly and can help a patient suffering from upper limb dyskinesia performe upper limb rehabilitation training to fulfill the aim of enhancing the rehabilitation effect.

Description

technical field [0001] The invention belongs to the technical field of rehabilitation robots, in particular to a two-degree-of-freedom upper limb rehabilitation training robot system. Background technique [0002] For patients with stroke sequelae, rehabilitation training for their hemiplegia is a very important medical method, and early rehabilitation training can significantly reduce the possibility of disability. In traditional rehabilitation therapy, the therapist usually conducts monotonous one-on-one rehabilitation training to patients, lacking objective data to scientifically evaluate training parameters and rehabilitation effects, and it is difficult to optimize training parameters to obtain the best therapeutic effect. Therefore, it is of great application value and practical urgency to apply robot technology to the field of rehabilitation and develop a rehabilitation training robot that meets the needs of rehabilitation to improve the efficiency and effect of rehab...

AI Technical Summary

Problems solved by technology

[0006]1. Most of them are in series structure, the branch chain is long, takes up a lot of space, is heavy, and requires a large driving force

[0007]2. Most rehabilitation robots have complex structures and relatively high requirements for control methods and safety

[0008]3. Lack of necessary support and protection measures for patients who have difficulty in overcoming their own gravity

[0009]4. There are relatively few types of training movements for patients and they are limited to certain single movements, which makes it difficult to improve the enthusiasm of patients for rehabilitation training
