Zusammenfassung:	Disclosed is an ultrasonic surgical device having an external protective film attached thereto. A purpose of one embodiment of the present invention is to provide: a piezoelectric device having a protective film attached thereto so that the brittleness of the piezoelectric device may be compensated for when driving an ultrasonic surgical device; and an ultrasonic surgical device comprising same. La présente invention concerne un dispositif chirurgical ultrasonore ayant un film protecteur externe fixé à ce dernier. Un but d'un mode de réalisation de la présente invention est de fournir : un dispositif piézoélectrique ayant un film protecteur fixé à ce dernier de sorte que la fragilité du dispositif piézoélectrique puisse être compensée lors de la commande d'un dispositif chirurgical ultrasonore ; et un dispositif chirurgical ultrasonore le comprenant. 외부 보호막이 부착된 초음파 수술 장치를 개시한다. 본 발명의 일 실시예는, 초음파 수술 장치를 구동함에 있어 압전 소자의 취성을 보완할 수 있도록 보호막이 부착된 압전 소자 및 이를 포함하는 초음파 수술 장치를 제공하는데 일 목적이 있다.
