Summary:The present invention relates to a method for manufacturing a cannula for face lift surgery and a cannula manufactured thereby. The method for manufacturing a cannula for face lift surgery comprises: melting a front end of a needle with a hollow part with a heat resource to form a blocked part; forming a semicircular opening on one side of the needle spaced apart at regular distance from the blocked part; and forming a medicine thread guide part using a bioabsorbable material in the hollow part between the opening and the blocked part. The cannula manufactured thereby can prevent a medicine thread from being damaged as inserted between the blocked part and the side of the needle. 본 발명은 피부 주름 성형용 캐뉼라의 제조방법 및 상기 방법으로 제조된 캐뉼라에 관한 것이다. 보다 구체적으로, 중공이 형성되어 있는 니들의 선단부를 열원으로 용융하여 봉쇄부를 형성하고, 상기 봉쇄부로 일정거리 이격된 니들에 일측면에 반원형의 개구부를 형성하며, 상기 개구부와 봉쇄부 사이의 중공에 생체흡수성 재료를 이용한 약실 가이드부를 형성하여, 상기 봉쇄부와 니들 측면 사이에 약실이 끼어 파손되는 것을 방지하는 피부 주름 성형용 캐뉼라의 제조방법 및 상기 방법으로 제조된 캐뉼라에 관한 것이다.
