Abstract: The system includes a memory that stores a trained model, and a processor. The processor acquires a pre-treatment image in which at least one energy device and at least one biological tissue are imaged, and a state before application of energy is imaged. The processor estimates an estimated heat diffusion region from the pre-treatment image and information regarding an energy supply amount by processing based on a trained model stored in the memory. The processor superimposes the estimated heat diffusion region on a captured image of the camera and displays the captured image with the superimposed estimated heat diffusion region.

Abstract: The system includes a memory that stores first and second trained models, 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 detects a bounding box from the captured image by processing based on the first trained model and estimates the image recognition information from the captured image in the bounding box by processing based on the second trained model. The processor outputs an energy output adjustment instruction based on the estimated image recognition information to the generator. The generator controls the energy supply amount to the energy device based on the energy output adjustment instruction.

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 medical system includes a treatment tool provided with an end effector that treats a tissue, an imager capturing an image of the tissue, and a processor. The processor acquires color information of a target tissue from the captured image output from the imager. The target tissue is a portion of the tissue that covers at least a portion of the end effector that has slid into the tissue. The processor estimates a force applied to the target tissue by the end effector from the color information of the target tissue. The processor notifies an operator of a result of the estimation of the force.

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.
