ULTRASONIC SCALPEL BIT, ULTRASONIC VIBRATION PROPAGATION ASSEMBLY AND ULTRASONIC HEMOSTASIS AND CUTTING SYSTEM

摘要

Disclosed is an ultrasonic hemostasis and cutting system, comprising an ultrasonic vibration propagation assembly. An ultrasonic scalpel head (101) in the ultrasonic vibration propagation assembly comprises an ultrasonic scalpel tip (11), a connecting part (13), vibration node bosses (14) and a waveguide (15), wherein the ultrasonic scalpel tip (11) is arranged in front of the waveguide (15), the connecting part (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 tip thereof, and a vibration guide groove (12) is further provided in the ultrasonic scalpel head (101). By designing the ultrasonic scalpel head as a bent shape and converting longitudinal ultrasonic vibration into longitudinal and torsional compound vibration, temperature uniformity inside a cut or coagulating tissue can be improved, thus the efficiency and safety of hemostasis and cutting are improved.
