Summary:The present invention relates to an endoscopic joint structure which can be bent in a desired direction by using magnetic force of electromagnets and thus does not need an additional bending device or operational force. More particularly, node units, including electromagnets formed on upper sides, lower sides, left sides, and right sides, are joined to each other while being placed apart from each other; currents in different polarity directions are provided to one row of the electromagnets facing each other; and the electromagnets are attracted to each other to come in close contact with each other as attractive force is generated on each electromagnet. Current in the same polarity direction is provided to the other row of the electromagnets to generate repulsive force on each electromagnet, and consequently the node units are bent. When power supply to the electromagnets is cut, the node units restore original positions by elasticity. Therefore, the node units can be bent in any direction without limitation by using repulsive force and attractive force of the electromagnets. 본 발명은 전자석의 자력을 이용하여 원하는 방향으로 굴곡시킬 수 있어 별도로 굴곡을 위한 장치나 작동력을 필요로 하지 않는 내시경관절 구조에 관한 것으로, 더욱 상세하게는 상하좌우에 전자석이 형성된 마디부가 서로 이격된 상태로 연결되어, 마주보는 전자석 중 일 열에는 전류의 극성 방향을 서로 다르게 각각 공급하여 각 전자석에 인력이 발생하여 밀착되며 당겨지고, 상기 전자석 중 타 열에는 전류의 극성 방향을 동일하게 각각 공급하여 각 전자석에 척력이 발생하여 밀어서 마디부가 굴절되며, 상기 전자석에 전원을 차단하면 탄성력에 의해 최초 위치로 복원되도록 구성하여; 굽힘 방향을 전자석의 자력에 의한 반발력과 인력을 이용하여 자유자재로 굴곡 시킬 수 있는 효과가 있다.
