摘要：
Disclosed is an ultrasonic hemostasis and cutting system, comprising an ultrasonic vibration propagation assembly. An ultrasonic scalpel bit (101) of the ultrasonic vibration propagation assembly comprises an ultrasonic scalpel tip (11), a connection portion (13), vibration node bosses (14) and a waveguide (15), wherein the ultrasonic scalpel tip (11) is arranged in front of the waveguide (15), the connection portion (13) is arranged behind the waveguide (15), the vibration node bosses (14) are arranged on the waveguide (15), the ultrasonic scalpel tip (11) is laterally bent at a pointed end thereof, and a vibration guide groove (12) is further provided on the ultrasonic scalpel bit (101). By designing the ultrasonic scalpel bit in a bent shape and converting a longitudinal ultrasonic vibration into a longitudinal torsional composite vibration, temperature uniformity inside a tissue being cut or coagulated can be improved, thereby improving the efficiency and safety of hemostasis and cutting.
