An ultrasonic surgical instrument includes an ultrasonic transducer configured to vibrate ultrasonically, a probe configured to treat a living tissue by the ultrasonic vibration, a detector configured to detect a pressing force of the probe against the living tissue, a memory configured to store a predetermined value related to a pressing force in accordance with the living tissue, a comparing section configured to compare the pressing force detected by the detector with the predetermined value stored in the memory, and a notification section configured to perform a notification in response to a comparison result obtained by the comparing section.

Ultrasonic surgical instrument and processing method for ultrasonic surgical device

A vagus nerve is efficiently stimulated while preventing wasteful energy consumption. Provided is a nerve stimulating device () including a stimulation-signal outputting portion () that outputs a stimulation signal to a vagus nerve (B); a heart-event detecting portion () that detects a heart event; and a control portion () that makes a judgment regarding the responsiveness of a heart (A) based on the heart event detected by the heart-event detecting portion () in response to the stimulation signal output from the stimulation-signal outputting portion (), and that controls the stimulation-signal outputting portion () so that an intensity of the stimulation signal is decreased when the responsiveness of the heart (A) is decreased.
