Abstract: A system includes a memory that stores a trained model and a processor. The processor acquires a captured image in which at least one energy device and at least one biological tissue are imaged. The processor performs a process based on the trained model stored in the memory to estimate a heat diffusion region and a specific tissue region from the captured image. The processor determines a risk for heat damage on a specific tissue by energy output from the energy device from the estimated heat diffusion region and the estimated specific tissue region.

Abstract: A treatment device for a medical treatment heats a biotissue at a desired temperature, and includes a treatment tool, a controller and a storage section. The treatment tool includes a heat transfer portion which contacts with the biotissue to transfer heat to the biotissue, and a resistance element into which power is supplied to heat the heat transfer portion. The controller is detachably attached to the treatment tool, and measures a resistance value R of the resistance element. The storage section stores a coefficient C2. The controller calculates a coefficient C1 based on a calibration temperature when the treatment tool is connected to the controller. The controller calculates a temperature of the resistance element using the R, C1 and C2, and controls the temperature of the heat transfer portion.
