Handpiece capable of attaching/detaching vacuum cap and adjusting angle of vacuum cap

Abstract

Provided in the present invention is a handpiece (300) for a treatment device with improved stability and hygiene function by being configured so as to freely adjust the angle of a vacuum cap depending on a treatment site and to attach/detach the vacuum cap to/from the handpiece (300). The handpiece (300) capable of attaching/detaching a vacuum cap and adjusting an angle of the vacuum cap comprises: a vacuum cap (310) having an open lower surface and a hollow part formed therein; a body part (410) configured to attach/detach the vacuum cap (310) thereto/therefrom; a vacuum device (350) for providing a reference negative pressure to the vacuum cap so that a target site of the skin can be adhered toward the hollow part of the vacuum cap; a reference negative pressure variable device (360) for varying the reference negative pressure in a pulse form under the condition in which the hollow part of the vacuum cap (310) maintains the negative pressure; RF electrodes (320, 321) configured to be exposed to the inside wall of the vacuum cap (310) so that, when the target site of the skin has been adhered toward the hollow part of the vacuum cap (310), the skin adhered toward the hollow part comes into contact with the inside of the hollow part of the vacuum cap (310); and a control unit (380) for controlling driving of the vacuum device (350), the reference negative pressure variable device (360), and the RF electrodes (320, 321). The driving of the reference negative pressure variable device (360) and the RF electrodes (320, 321) for treating the target site of the skin is controlled so as to select any one of single driving, simultaneous driving, and alternating driving. The attachment/detachment of the vacuum cap (310) to/from the body part (410) is made by simultaneous coupling or simultaneous separation of a vacuum cap connection unit (430) that consists of a vacuum tube coupler (432) configured at an end of the body part (410), power supply connectors (433, 434), and a clip (435).
