Abstract: The system includes a memory that stores a trained model, and a processor. The processor acquires at least one treatment image including an image in which at least one energy device and at least one biological tissue are captured. The processor acquires information regarding an amount of energy supply, the information regarding an energy output setting of the energy device. The processor estimates, based on the treatment image, the information regarding the amount of energy supply, and the trained model, estimated remaining heat information regarding an amount of heat or a temperature of the energy device. The processor causes a notification section to make a notification based on the estimated remaining heat information.

Abstract: Provided is an endoscope system including an endoscope that images living tissue to be treated by at least one instrument; and a control device that includes a processor configured to derive at least one of the following information: grasp assistance information on a grasping operation to grasp the living tissue by the at least one instrument, and traction assistance information on a traction operation for traction of the living tissue by the at least one instrument, based on an endoscopic image acquired by the endoscope.
