Abstract

The invention discloses upper limb rehabilitant robot fingers and a wrist training device. The device comprises an installation base, a wrist rotary movement mechanism and a finger gripping and stretching exercise mechanism, wherein the wrist rotary movement mechanism is driven by a first servo motor through a two-stage reducing mechanism; a first-stage reducing mechanism is a gear reducer and is arranged on the front end of the first servo motor; a second-stage reducing mechanism is formed by intertwining a shaft sleeve and a rotary semi-circular ringthrough steel wire ropes and is located on the front end of the first-stage reducing mechanism; the first servo motor is arranged on the installation base; the finger gripping and stretching exercise mechanism is driven by a second servo motor through a two-stage reducing mechanism; a first-stage reducing mechanism is a gear reducer and is arranged on the front end of the second servo motor; the second servo motor is arranged on a palm support plate; the palm support plate is fixed on the rotary semi-circular ring of the wrist rotary movement mechanism. The wrist training device provided by the invention is simple in structure and strong in functionality.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to rehabilitation robot technology, and in particular to an upper limb rehabilitation robot finger and wrist training device. Background technique [0002] With the intensification of the aging of Chinese society, more and more elderly people suffer from upper limb paralysis due to stroke and other reasons, which brings great inconvenience to daily life. Paralyzed patients can stimulate brain plasticity through a large number of rehabilitation training, restore certain motor ability, realize self-care, improve quality of life, and return to society to the greatest extent. Robot-assisted rehabilitation training can save a lot of manpower and material resources, and can conduct real-time quantitative evaluation of the patient's rehabilitation level, and carry out training step by step according to the patient's rehabilitation status. [0003] Patients with upper limb hemiplegia are g...
