Harmonic Ultrasound transducer repair
Ultrasonic knife is the conversion of electrical energy into mechanical energy, through the ultrasonic transducer so that the ultrasonic knife head to a certain frequency of mechanical oscillation, the highest vibration frequency of up to 55,000HZ, so as to make the protein hydrogen bond break and protein structure reorganization, and then achieve cutting, hemostasis, separation and other functions. It can deal with both parenchymal tissue and connective tissue, cut larger pieces of tissue, and can be used for both luminal surgery and open surgery. The various styles of cutter head can meet the needs of different departments and surgeries in hospitals, which not only makes the operation convenient, but also makes the cutting and hemostasis more precise, with superior performance and clinical use, but also is a common surgical tool.
