The Ultrasonic System is intended to be used to transect, dissect, and coagulate tissue. The instruments are indicated for use in open and endoscopic general surgical procedures where bleeding control and minimal thermal injury to tissue are desired. The instruments allow for the coagulation of vessels (veins and arteries) up to 3 mm in diameter.

Ultrasonic Surgical System is an ultrasonic dissection and coagulation system composed of four components: Ultrasonic Generator (HD-CSD01), Hand Piece (HD-CSH01), a disposable Ultrasonic Shears includes 4 shaft lengths (HD-CS-DJ45, HD-CS-DJ36, HD-CS-DJ22, HD-CS-DJ14) and foot switch (HRF-M52). A disposable Ultrasonic Shears is a sterile component that has undergone EO sterilization, including an ultrasonic horn, jaws, main shaft, axis rotation, handle, operating handle, and control switch. The operating handle is used to open and close the jaws that grip the tissue. The Ultrasonic Surgical System can simultaneously cut and coagulate tissues by setting different output power levels. The high-power range allows for faster tissue cutting, while the low-power range allows for better tissue closure. The ultrasonic frequency current in the ultrasonic generator is transmitted to the hand piece, which converts electrical energy into mechanical energy for forward and backward vibration. Through the transmission and release of the blade, the end of the blade vibrates at a certain frequency. The heat generated by friction causes water vaporization in the tissue cells that come into contact with the blade, protein hydrogen bonds break, cells collapse and the tissue is cut open after solidification; When cutting blood vessels, the knife head contacts with Histone and generates heat through mechanical vibration, leading to the destruction of the collagen structure in the tissue, causing the protein to coagulate, and then sealing the blood vessels to stop bleeding. The disposable ultrasonic shears are EO sterilized, but the other parts are non-sterilized packaging, and the hand piece must be cleaned and sterilized by the user before being used for surgery. This device is intended to be used in the hospital environment, such as surgical operation room and imaging intervention room.
