Abstract
The tissue removal device using focused ultrasound includes a focused ultrasound output unit, a mode setting unit to set an output mode of the focused ultrasound, and a control unit to control output characteristics of the focused ultrasound according to the set mode, wherein the output mode is selected from a first mode for removing a tissue in a local area using a vapor bubble formed by the focused ultrasound, a second mode for removing a tissue in a narrower area than the first mode by controlling the output characteristics of the focused ultrasound immediately after the vapor bubble is formed by the focused ultrasound, and a third mode for obtaining a skin tightening effect by generating heating in a subcutaneous fat layer using focused ultrasound of lower intensity and a longer pulse length than the first mode and the second mode.
