Today’s Patent – Handpiece For Non-Focused Ultrasound Treatment
The said invention (US12179043B2) was invented by Sun Young Kang and patented by USPTO on April 24th, 2023. Currently, it stands assigned to the Shenb Co Ltd.

The present disclosure pertains to a handpiece designed for non-focused ultrasound treatment. The device includes a housing and a detachable cartridge. The cartridge features an ultrasound generator with a transducer, a skin cooling unit, and an EMS (Electrical Muscle Stimulation) unit that delivers electrical stimulation to the user’s skin.
The skin cooling unit comprises a cooling case and a thermoelectric element that draws heat away from the cooling case. The cooling case includes an opening through which ultrasound waves emitted by the transducer are transmitted. Surrounding this opening is a contact surface that touches the user’s skin to absorb heat. This contact surface creates a cooling barrier beneath the skin in the area where ultrasound waves are delivered, enhancing the treatment’s comfort and effectiveness.
