The invention provides a wearable medical-
rehabilitation walking aid device. The wearable medical-
rehabilitation walking aid device comprises a
waist sleeve and a first support rod, a two-freedom-degree rotating mechanism, a second support rod, a
thigh sleeve, a third support rod, a rotary disc, a fourth support rod and a shank load-bearing mechanism which are sequentially connected with the
waist sleeve from top to bottom, wherein the
waist sleeve is tied around the waist of a
human body, the two-freedom-degree rotating mechanism located on the outer side of the hip joint, the
thigh sleeve is provided with a hanging ring, the rotary disc is located on the outer side of the
knee joint, the shank load-bearing mechanism is arranged at the shank, an electric winding mechanism is arranged on each of the front and the waist side of the waist sleeve, a
clockwork spring component is arranged in the rotary disc, and the hanging ring and the rotary disc are respectively connected with the two electric winding mechanisms through pulling wires. The wearable medical-
rehabilitation walking aid device has the advantages that rotary clamp plates are used to match with the freedom degree of the hip joint of the
human body during walking, and motors are used to drive the pulling wires to provide
active force for a hemiplegia patient to help the flexion and extension of the hip joint and the
knee joint of the patient so as to aid the rehabilitation walking of the patient.
