A multifunctional surgical instrument, comprising a housing (11), a trigger (16) provided on the housing (11), an ultrasonic transducer provided inside the housing (11), and a blade shaft assembly that transmits ultrasonic energy generated by the ultrasonic transducer and electrical energy generated by the system. The blade shaft assembly comprises a waveguide (1), with a proximal end thereof being fixedly connected to the ultrasonic transducer, and a distal end thereof extending out of the housing (11) and forming an ultrasonic blade. A clamping arm (7) is opened and closed relative to the waveguide (1) under the action of a first driving force. A monopolar sleeve (4) is sleeved on an outer side of the waveguide (1) and is axially movable relative to the housing (11) under the action of a second driving force. The surgical instrument is a multifunctional surgical instrument combining ultrasonic energy and high-frequency energy, can achieve the function of hemostasis by means of ultrasonic cutting, and can also achieve the function of a monopole high-frequency electrotome. The surgical instrument integrates the functions of two surgical knives, which simplifies the process of frequently switching between surgical knives in an operation room and is convenient for a surgeon to use, and same also has a simultaneous trigger preventing structure, which can effectively prevent switches from being simultaneously triggered.
