Title:
RADIO FREQUENCY MICRO-NEEDLE ARRAY CONTROL DEVICE AND METHOD, AND RADIO FREQUENCY MICRO-NEEDLE THERAPEUTIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/244435
Kind Code:
A1
Abstract:
A radio frequency micro-needle array control device and method, and a radio frequency micro-needle therapeutic apparatus. Said device comprises: a micro-needle array (30); an on/off switching circuit (40), an input end of the on/off switching circuit (40) being connected to a power supply (10), two first output ends of the on/off switching circuit (40) being electrically connected to the micro-needle array (30) by means of a PCB (410), a second output end of the on/off switching circuit (40) being electrically connected to a return electrode (20); and a main controller (50), wherein in a single-electrode mode, the main controller (50) controls the on/off switching circuit (40) to be connected to the power supply (10), the micro-needle array (30), and the return electrode (20), a plurality of micro-needle electrodes (420) in the micro-needle array (30) having the same electrode polarity, and wherein in a dual-electrode mode, the main controller (50) controls the on/off switching circuit (40) to be connected to the power supply (10) and the micro-needle array (30), at least one micro-needle electrode (420) in the micro-needle array (30) having an electrode polarity opposite to that of the remaining micro-needle electrodes (420). The radio-frequency micro-needle array control device can realize single-electrode and dual-electrode switching of micro-needles, so that an effect region of micro-needles has a good therapeutic effect in terms of both the width in a horizontal direction and the depth in a direction perpendicular to the skin.
