Abstract: In an energy treatment unit and an energy treatment instrument, a jaw openable and closable relative to a probe distal portion of a probe is attached to a distal portion of an energy transmission portion. A liquid feed conduit extends between the energy transmission portion and the probe in a cavity portion, and a liquid ejected from an ejection port, that is formed at a distal end of the liquid feed conduit, flows into a jaw cavity in an inside of the jaw. A liquid outflow portion is provided on an outer surface of the jaw, and the liquid flowing into the jaw cavity flows to an outside of the jaw from the liquid outflow portion.

Abstract: A treatment system can include a treatment tool including an ultrasound transducer and an end effector. The system can also include an ultrasound power source configured to output a drive signal to the ultrasound transducer, and a processor configured to detect an abnormality in the end effector, and whether end effector is immersed in a liquid. The system can continue an output of the drive signal from the ultrasound power source to the ultrasound transducer when the abnormality is detected and the end effector is immersed in the liquid.
