  • Patent number: 12220148
    Abstract: A prepuce extruding, cutting, hemostasis, and healing assembly using ultrasonic wave. Ultrasonic wave is applied in extruding, cutting, hemostasis, and healing of prepuce at a conjunction of internal and external tissues of a distal part of a human body. The assembly includes an ultrasonic generating device, a transmission device and a circumcision device. The ultrasonic generating device is used for generating ultrasonic waves, is connected to the transmission device and can send the ultrasonic waves to the transmission device. The transmission device is connected to the circumcision device and can send the ultrasonic waves to the circumcision device. The circumcision device is used for extruding and cutting a prepuce and/or performing hemostasis and/or healing of wounds. In this way, circumcision can be completed within just several seconds, and immediate healing can be achieved, preventing bleeding during and after a surgery.
