摘要：
The present invention relates to an artificial femoral limb capable of sensing operation, the artificial femoral limb which can accurately recognize a state of an angle of a knee joint. The artificial femoral limb comprises: an upper socket joining unit (10) of the artificial femoral limb； and a knee joint unit (20) comprising a joint axis hole (22) which is joined, to be able to rotate, to a joint axis (21) fixated to a lower leg frame (40) to support the upper socket joining unit (10) and to perform joint movement, a cylinder rod axis hole (24) which is joined to a cylinder rod axis (23) in an eccentric location with respect to the joint axis hole (22), an arc-type groove (25) which is formed in the shape of an arc around an entrance of the joint axis hole (22) and has a tapered length, a small-sized magnet (26) which is inserted and fixated to a tapered groove bottom from the arc-type groove (25), and a hole sensor (28) which senses a change in the level of magnetism, depending on the location of the small-sized magnet (26) installed in the groove of the lower leg frame (40), as a change in the angle of a knee joint. The hole sensor (28) is formed to be located on the lower end portion of the arc-type groove (25) of a knee joint body (29) in a state of a vertical stance phase.본 발명은 대퇴의지의 상부소켓연결부(10)와；상부소켓연결부(10)를 지지하고 관절운동을 하도록 하퇴프레임(40)에 고정된 관절축(21)에 회전가능하도록 결합하는 관절축공(22)과, 관절축공(22) 기준으로 편심위치에서 실린더로드축(23)과 유착되는 실린더로드축공(24)과, 관절축공(22) 입구 둘레에 호형으로 형성되고 깊이가 테이퍼진 호형홈(25)과, 호형홈(25)에 연속하여 테이퍼진 홈바닥에 끼움 고정되는 소형자석(26)과, 하퇴프레임(40)의 홈에 설치된 소형자석(26)위치에 따른 자석세기 변화를 슬관절각도 변화로 인식하는 홀센서(28)를 가지는 슬관절부(20)； 를 포함하고,상기, 홀센서(28)는 수직 입각기 상태의 슬관절 몸체(29)의 호형홈(25)의 하단 위치에 오도록 구성한 작동인식 가능한 대퇴의지이다.
