Medical device, medical system, medical device operation method, and computer-readable recording medium

A medical device, comprising:

• a processor comprising hardware, the processor being configured to
• determine, based on a fluorescence image based on fluorescence generated by excitation light that excites a substance produced by cauterization using an energy device and output information on the energy device, an off-time generated fluorescent region that has been generated during an off-state of output of the energy device, and
• when it is determined to be the off-time generated fluorescent region, execute a notification process of notifying that a fluorescent region has been generated during the off-state of output of the energy device.

A medical device operation method executed by a medical device, the method comprising:

• generating a fluorescence image based on fluorescence generated by excitation light that excites a substance produced by cauterization using an energy device,
• determining, based on output information on the energy device and on the fluorescence image, an off-time generated fluorescent region that has been generated during an off-state of output of the energy device, and
• when it is determined to be the off-time generated fluorescent region, notifying that a fluorescent region has been generated during the off-state of output of the energy device.

A non-transitory computer-readable recording medium with an executable program stored thereon, the program causing a medical device to execute:

• generating a fluorescence image based on fluorescence generated by excitation light that excites a substance produced by cauterization using an energy device,
• determining, based on output information on the energy device and on the fluorescence image, an off-time generated fluorescent region that has been generated during an off-state of output of the energy device, and
• when it is determined to be the off-time generated fluorescent region, notifying that a fluorescent region has been generated during the off-state of output of the energy device.
