US 2026/0199714 A1 · ULTRASONIC TREATMENT DEVICE

Abstract

An ultrasonic treatment device includes an ultrasonic treatment tip and a cooling mechanism. The ultrasonic treatment tip includes a sealed cavity, a sound-transferring medium disposed inside the sealed cavity, a treatment window and a heat-transferring surface. The ultrasonic treatment tip is configured for outputting ultrasonic waves to a treatment area through the treatment window. The heat-transferring surface is intimately surrounding the treatment window and thermally contacted with the treatment area. The cooling mechanism is configured to discharge heat generated at the treatment area outside of the ultrasonic device by thermally contacting the heat-transferring surface.

Dependent claims

An ultrasonic treatment device, comprising:

an ultrasonic treatment tip comprising a transducer and a treatment window, wherein the transducer is configured to generate first heat in a treatment area via an ultrasonic wave through the treatment window;
a semiconductor assembly configured to cool the treatment area by being in thermal contact with the treatment window, or generate second heat, wherein the second heat is at least partially overlapped with the first heat from the ultrasonic wave in the treatment area;
and
a controller configured to control the transducer and the semiconductor assembly.
