摘要： Provided is a real-time impedance matching method for a high-frequency treatment device, the method including: fixing, to a preset inductance in a reference impedance setting step, inductance of a first variable inductor part for measuring impedance in the high-frequency treatment device and inductance of a second variable inductor part for measuring impedance in a patient's body; applying, in a minimum impedance search step, a search voltage lower than a medical procedure voltage and searching for a minimum impedance by changing the inductance of the first variable inductor part and the inductance of the second variable inductor part; measuring, in a reflected wave measurement step, at least two reflected waves under a condition in which the inductance of the first variable inductor part and the inductance of the second variable inductor part are varied; comparing, in a reflected wave minimum value search step, the measured reflected waves to search for the reflected wave having a minimum value; determining, in an inductance determination step, the inductance of the first variable inductor part and the inductance of the second variable inductor part that satisfy the reflected wave minimum value; and operating, in a high-frequency application step, the high-frequency treatment device with the medical procedure voltage to apply high-frequency waves to the patient's skin under a condition of the inductance of the first variable inductor part and the inductance of the second variable inductor part determined in the inductance determination step.

摘要： Proposed is a vibration unit available for eyesight recovery glasses, the vibration unit being mounted on any one side or each of left and right eye sides of a frame unit of the eyesight recovery glasses. The vibration unit is configured to generate ultrasonic waves through vibration. Accordingly, ultrasonic waves in a low frequency band are directly transmitted to the eyeball rather than inducing an eye movement, thereby being capable of providing the vibration unit available for the eyesight recovery glasses realizing a substantial eyesight recovery effect. In addition, the ultrasonic waves transmitted to the eyeball may help to relieve eye strain, to increase blood flow, and to activate eye cells.
