Zusammenfassung:The present invention relates to an end effector for ultrasound operating equipment to perform cutting and hemostasis quickly and effectively. According to the present invention, the end effector for ultrasound operating equipment is operated to cut or coagulate tissue on the basis of an ultrasonic signal. According to the present invention, the end effector comprises: a blade having a first curved surface formed with a preset curvature, having a protrusion formed in the longitudinal direction on the inside of the first curved surface, and vibrating in the transverse direction according to an ultrasonic signal while tissue comes in contact with the inner side of the first curved surface, thereby cutting or coagulating the tissue; and a jaw including a second curved surface corresponding to the first curved surface to engage with the curved surface of the blade. 본 발명은 초음파 수술기의 엔드 이펙터에 관한 것으로서, 초음파 신호에 기초하여 조직이 절단 또는 응고되도록 구동되는 초음파 수술기의 엔드 이펙터(End Effector)에 있어서, 기 설정된 곡률로 형성된 제1 굴곡면을 가지며, 상기 제1 굴곡면의 내측에 길이방향으로 돌출부가 형성되고, 상기 제1 굴곡면의 내측에 조직이 접촉한 상태에서 상기 초음파 신호에 따라 횡방향으로 진동하면서 조직의 절단 또는 응고 기능을 수행하는 블레이드(blade); 및 상기 블레이드의 굴곡면과 맞물리도록 상기 제1 굴곡면에 대응하는 제2 굴곡면을 가지는 턱(jaw)을 포함하는 것을 특징으로 한다.
