The present invention relates to an ultrasonic hand piece cartridge and an ultrasonic hand piece equipped with the same. According to the present invention, subcutaneous fat deterioration and lipolysis can be maximized within a non-overlapping range while a hand piece movement is minimized. The present invention includes a cartridge (20) and a handler (10). The cartridge (20) is provided with a cartridge main body (21), a liquid medium (Lq) with which the cartridge main body (21) is filled, and ultrasonic vibrators (22) arranged in the cartridge main body (21) in a square or rectangular form, performing ultrasonic focusing on subcutaneous fat by a non-skin contact method, performing subcutaneous fat deterioration and lipolysis, and operated in a sequential manner. The handler (10) is provided with a handler main body (11) and a first pusher (12). The handler main body (11) is provided with an accommodating portion and a locking jaw (11a) therein such that the cartridge (20) is inserted and coupled by a medium of an elastic piece (21b-1). The first pusher (12) is disposed in the handler main body (11) and presses the elastic piece (21b-1) so that the elastic piece (21b-1) is separated from the locking jaw (11a). According to this embodiment, the ultrasonic vibrators that are arranged in the square or rectangular form are individually operated in the sequential manner, and thus no great power is required when the present invention is used and power consumption can be reduced. In addition, the subcutaneous fat deterioration and lipolysis can be maximized within the non-overlapping range even when an operator does not move the ultrasonic hand piece, and thus a highly convenient and effective operation can be performed.COPYRIGHT KIPO 2016본 발명은 핸드피스의 움직임을 최소화하면서 중첩되지 않는 범위 내에서 최대한 피하지방을 열화시켜 분해할 수 있는 초음파 핸드피스용 카트리지와 이를 갖춘 초음파 핸드피스에 관한 것으로서, 카트리지본체(21), 카트리지본체(21)의 내부에 충진되는 액상의 매질(Lq), 카트리지본체(21)의 내부에 정방형 또는 장방형으로 배치되어 피부 비접촉방식으로 피하지방에 초음파를 집속하여 피하지방을 열화시켜 분해하며 순차적으로 동작하는
