Abstract: An explosion-proof structure includes a partition wall that partitions a sealed space in a container and wiring that connects the interior and the exterior of the sealed space. The partition wall includes a filling portion through which the wiring passes. The filling portion includes an inner peripheral wall surface that defines an opening having a central axis that passes through the partition wall, a filler that seals a gap between the inner peripheral wall surface and the wiring, a first peripheral groove provided on the inner peripheral wall surface and filled with the filler, and a second peripheral groove provided on the inner peripheral wall surface and filled with the filler. This explosion-proof structure is capable of improving the seal of the filling portion.

Abstract: 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.

Abstract: A vagus nerve is efficiently stimulated while preventing wasteful energy consumption. Provided is a nerve stimulating device (1) including a stimulation-signal outputting portion (3) that outputs a stimulation signal to a vagus nerve (B); a heart-event detecting portion (2) that detects a heart event; and a control portion (4) that makes a judgment regarding the responsiveness of a heart (A) based on the heart event detected by the heart-event detecting portion (2) in response to the stimulation signal output from the stimulation-signal outputting portion (3), and that controls the stimulation-signal outputting portion (3) so that an intensity of the stimulation signal is decreased when the responsiveness of the heart (A) is decreased.

Abstract: Nerve stimulation is performed while suppressing occurrence of symptom caused by sinus node dysfunction or atrioventricular node dysfunction. Provided is a nerve stimulation apparatus including: a stimulation signal generator configured to output a stimulation signal to a nerve; a cardiac-event acquisition unit configured to acquire cardiac events; and a control unit configured to control the stimulation signal generator such that sinus node dysfunction or atrioventricular node dysfunction is determined to be occurring and energy of the stimulation signal is reduced when a time interval value between the adjacent cardiac events acquired by the cardiac-event acquisition unit exceeds a predetermined threshold.
