Abstract

The invention discloses a knee, hip and ankle joint dysfunction energizing device, which comprises a hip joint power assisting mechanism, a knee joint power assisting mechanism, a knee joint power assisting mechanism, a knee joint power assisting mechanism, a knee joint power assisting mechanism, a knee joint power assisting mechanism and a knee joint power assisting mechanism, the knee joint assisting mechanism comprises two connecting seats, thigh connecting rods are hinged to the upper ends of the connecting seats, shank connecting rods are hinged to the lower ends of the connecting seats, the two thigh connecting rods are connected with a thigh protecting plate and a thigh protecting belt, a first spring is arranged between the thigh protecting plate and the connecting seats, and the two shank connecting rods are connected with a shank protecting plate and a shank protecting belt. The ankle joint assisting mechanism comprises a heel pad, a second ratchet wheel and a second pawl are arranged on an arc-shaped frame of the heel pad, a rack and a gear are arranged in a cavity of the heel pad, a control line is connected to a shaft of the gear, and a traction belt is connected with the upper end of a thigh connecting rod. The pull rope is connected with the shank connecting rod and the second ratchet. The problems that an existing exoskeleton device is not beneficial to daily use and high in price are solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for energizing the dysfunction of three joints of knee, hip and ankle. Background technique [0002] The hip, knee and ankle joints are the three main motion joints of the lower limbs of the human body, and their flexion, extension, rotation and other functions are the basis of the walking function. However, when the flexion, extension and rotation functions are lost due to the disease of these three joints, the patient's autonomous walking function will be completely lost, and traditional assisted walking methods such as crutches are also ineffective. [0003] In recent years, exoskeletons have emerged as a promising solution, but they are expensive, relatively complicated to operate, and inconvenient for single-person use, limiting their applications. [0004] The present invention provides a new idea, through a three-joint dysfunction energizing device of kne...
