The present invention relates to a medical cannula for connecting the inside of the human body with the outside by being put in place so as to be inserted inside the human body during a medical operation, and more specifically relates to a length-adjustable cannula which is supported by adjusting the position of an outside support plate in accordance with the length between an operating site and the skin, such that the adjusted outside support plate is in contact with the skin while an inside support plate, that has been inserted inside the body, is in contact with the endothelium inside the body, thereby allowing the length-adjustable cannula to be stably installed in different subjects undergoing various medical operations, regardless of distances of different lengths between the skin and the operating site.La présente invention concerne une canule médicale destinée à raccorder lintérieur du corps humain à lextérieur en étant mise en place de façon à être insérée à lintérieur du corps humain pendant une opération médicale, et concerne plus spécifiquement une canule réglable en longueur qui est supportée en réglant la position dune plaque dappui extérieure conformément à la longueur entre un site dopération et la peau, de telle sorte que la plaque dappui extérieure réglée est en contact avec la peau alors quune plaque dappui intérieure, qui a été insérée à lintérieur du corps, est en contact avec lendothélium à lintérieur du corps, ce qui permet à la canule réglable en longueur dêtre installée de façon stable chez différents sujets subissant diverses opérations médicales, quelles que soient la distance entre la peau et le site dopération.본 발명은 의료 시술시 인체 내부에 삽입되도록 꽂혀 외부와 인체 내부를 연결하는 의료용 캐뉼러에 관한 것으로, 더욱 상세하게는 시술 부위와 피부 사이의 길이에 따라 외측 지지판의 위치를 조절하고, 상기 조절된 외측 지지판은 피부에 접하고 인체 내부로 삽입된 내측 지지판은 신체 내부의 내피에 접하여 지지되도록 함으로써, 각각의 의료 시술 대상자마다 그 길이가 서로 다른 시술 부위와 피부 사이의 거리에 무관하게 안정적인 설치를 가능하게 하는 길이 조절형 캐뉼러에 관한 것이다.
