It is used to replace and release the lead wire of ultrasonic energy on the medical surgical transducer. Harmonic ultrasonic scalpel host, ultrasonic transducer, harmonic gen11 ultrasonic scalpel host. The vibration frequency of gen11 scalpel head is 55500hz, which is achieved by the current technology. It can cut and coagulate at the same time. The vibration amplitude of gen11 scalpel head is 60-100 microns, which ensures good cutting and coagulation effect. Gen11 is feasible for endoscopic surgery
