SUPPORTING AID WITH ROTARY TYPE AUTOMATIC JOINT LOCKING SYSTEM FOR LEG, AND OPERATION METHOD THEREOF

摘要

PURPOSE: A leg support assistance device which has a rotary type automatic arthrodesis apparatus and an operating method thereof are provided to stably support a body while working in a standing position with the legs bent by selectively limiting or blocking a circulation around a leg joint thereby automatically fixing the joint according to the choice of a wearer. CONSTITUTION: A leg support assistance device which has a rotary type automatic arthrodesis apparatus comprises: a top brace (100) which has a structure capable of attaching and detaching, and which is located in the upper part of the leg joints; a lower part brace (200) which has the structure capable of attaching and detaching, and which is located in the lower part of the leg joints; and an arthrodesis part (300) which selectively limits a circulation of the brace. An operating method of the leg support assistance device comprises the following steps. A motion detection sensor senses a movement of a wearer. The joint is fixed by blocking the circulation of the brace by operating the arthrodesis part in case the movement is not detected for a certain time. The arthrodesis part releases the blocking of the brace when the variation value which is measured in the pressure sensor or the strain gauge is greater than the pre-set value (Δα). When the variation value which is measured in the pressure sensor or the strain gauge is less than the pre-set value (Δα), the arthrodesis part blocks the circulation and fixes the joint until the variation value is greater than the pre-set value (Δα).
