Abstract

The invention discloses a quick hand traction device assisted by a soft hand exoskeleton. The quick hand traction device comprises a soft hand exoskeleton and a control system, wherein the soft hand exoskeleton comprises a hand back fixing device, the hand back fixing device is used for being fixed to a hand back to install one end of a soft driver, the other end of the soft driver is connected with a driver tail end fixing end, one end of a connecting rod is connected with the driver tail end fixing end, the other end of the connecting rod is connected with a finger tail end fixing clamp, the finger tail end fixing clamp is used for being installed on a fingertip. and the control system is connected with one end of the soft driver and is used for inflating and deflating the soft driver, so that the soft driver bends upwards back to the hand back during inflation to drive the bent fingers to stretch, and the soft driver recovers to the original shape during deflation so as to recover the bent state of the fingers. According to the invention, the quick hand traction device is large in output force, adjustable in output force and high and adjustable in traction frequency, and meets individual clinical requirements of patients.

Description

technical field [0001] The invention relates to the technical fields of sports training and neuromuscular rehabilitation, in particular to a hand rapid pulling device assisted by a soft hand exoskeleton. Background technique [0002] Spasticity is a positive motor dysfunction characterized by velocity-dependent increased muscle tone due to increased excitability of the stretch reflex. As one of the components of upper motor neuron injury syndrome, spasticity is another important manifestation besides muscle weakness in patients with neurological diseases such as stroke and motor dysfunction. During rehabilitation robot-assisted training, the appearance of spasticity will cause increased muscle tension and muscle stiffness, which will increase the stiffness and damping of the musculoskeletal system of the affected limb, thereby increasing the challenge and difficulty of sports rehabilitation and limiting the effective practice of coordinated movement. hinder the recovery of ...
