Description

Multi-HIFU device capable of simultaneous investigation of multiple areas {MULTI-HIFU DEVICE WITH PROVIDING HIFU ENERGY ON MULTIPLE AREA AT ONCE}

The present invention relates to a multi-hifu device capable of simultaneously irradiating multiple areas.

HIFU (High Intensity Focused Ultrasound) treatment is a non-invasive treatment technology that focuses high-intensity ultrasound on the treatment area of the body to induce fever or mechanical effect (Cavitation), which is used for tumor removal, skin care, and obesity management. it's technology

The HIFU device used in this HIFU procedure is provided in the form of a cartridge that generates HIFU energy to a handpiece that supplies power and provides HIFU energy to a set focusing depth.

At this time, the operator performs the HIFU procedure in a manner that provides HIFU energy to the treatment area while moving the handpiece along the treatment site, but the HIFU energy is provided in a focused form so that continuous treatment in point area units is inevitable, HIFU treatment for a large area has a problem that requires a lot of treatment time.
