Palm support-type finger rehabilitation training device and use method thereof

Abstract

The present invention discloses a palm support-type finger rehabilitation training device and a use method thereof. The device comprises a mounting seat, a finger rehabilitation training mechanism arranged on the mounting seat, and a driving mechanism for driving the finger rehabilitation training mechanism to move; the finger rehabilitation training mechanism comprises four independent and structure-identical finger training combined transmission devices respectively corresponding to an index finger, a middle finger, a ring finger and a little finger of a human body hand structure; the mounting seat has a supporting surface capable of supporting a human body palm; each set of the finger training combined transmission devices all comprises a MP motion sliding chute, a PIP finger sleeve, aDIP finger sleeve and a connecting rod transmission mechanism, a force sensor collects force feedback information to determine and conduct force stability control, and a space position sensor is usedto collect spatial angle information to realize real-time control of finger space positions. The method is suitable for assisting active and passive rehabilitation training of patients with hand hemiplegia due to stroke.

Description

technical field [0001] The invention designs a device for performing rehabilitation training on finger paralysis caused by cerebral apoplexy, and in particular relates to a fixed palm-supported exoskeleton rehabilitation training hand. Background technique [0002] Stroke is a type of disease that causes pathological changes in the cerebral arterial and venous system due to various reasons. As an important human organ, the hand is an indispensable part of life and work. Paralysis of the head, relevant research shows that after certain rehabilitation training, 30% of patients can recover normal function, the traditional treatment method, for the treatment of patients with a dedicated therapist, the doctor conducts rehabilitation massage training for the patient, but this treatment method Depending on the experience and quality of doctors, the training effects of different doctors are quite different. Due to the limited treatment time and intensity of doctors, it is impossible...

Problems solved by technology

[0004] The Chinese patent application whose publication number is CN103750976A discloses a three-degree-of-freedom exoskeleton finger rehabilitation robot, and the Chinese patent application whose publication number is CN103767856A discloses a wearable five-finger rehabilitation manipulator. These devices play a certain role in the rehabilitation training of fingers. However, there are still some problems: (1) The above two devices are manipulators installed above the fingers, which exert a large support pressure on the patient's hand and easily cause secondary damage

(2) The above two devices perform certain rehabilitation training on human fingers, but the angle of finger movement is small, and the effect of rehabilitation training is discounted
