Abstract: A device for outputting a drive signal to a surgical instrument, comprising a housing. The housing is internally provided with: a power supply module, comprising a power supply module (121) and a power supply circuit board (122) for providing a power supply; a main board (123); an ultrasonic energy circuit board (124) connected to the main board (123) for generating an ultrasonic drive signal; and a high-frequency electric energy circuit board connected to the main board (123) for generating a high-frequency electric drive signal, wherein the projection of the ultrasonic energy circuit board (124) and the projection of the high-frequency electric energy circuit board on the bottom surface of the housing at least partially overlap, and a shielding unit is provided outside the ultrasonic energy circuit board (124) and/or the high-frequency electric energy circuit board.

Abstract: An output device for outputting drive signals to a surgical instrument and a surgical system. The device includes an ultrasonic energy source and a high-frequency electric energy source located in the same casing, a signal port, an ultrasonic signal acquisition circuit, a high-frequency electric signal acquisition circuit, and a control module, and the control module is configured to obtain adjustment parameters based on the feedback signals, and control the ultrasonic energy source and the high-frequency electric energy source to output drive signals based on the adjustment parameters. The surgical instrument includes one or more of an ultrasonic-electric scalpel, an ultrasonic scalpel, a monopolar electrotome, and a bipolar electrotome.
