1. A surgical device, comprising:
- a radio-frequency-signal-generation assembly including a radio-frequency-signal-generation circuit operable to generate a radio-frequency signal at an output and adapted to couple to a switch-mode power supply; and
a surgical handle including an end effector having at least one jaw with at least one electrical contact, the end effector including at least one signal input that electrically connects to the output to provide the radio-frequency signal at the at least one electrical contact.

23. A surgical device, comprising:
-
a radio-frequency-signal-generation assembly having; a switch-mode power supply; and a radio-frequency-signal-generation circuit having an output, being coupled to the switch-mode power supply, and being operable to generate a radio-frequency signal at the output; and a surgical handle having, a cautery end effector having at least one jaw with at least one electrical cautery contact, the cautery end effector having at least one signal input electrically coupling the at least one electrical cautery contact to the output to provide the radio-frequency signal at the at least one electrical cautery contact.
