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 processor of an electric power source device exercises control over a power output before a control switching time point based on a value related to initial impedance, and determines the control switching time point upon detecting that a value related to impedance of a living tissue is at a minimum. The processor sets a set electric-power value of the power output based on a parameter related to controlling the power output before the control switching time point, and performs constant-electric-power control by controlling the power output using the electric-power value at and after the control switching time point.
Abstract:
A treatment device includes a support section having conductivity, for which a separate position separated from the probe is switched to a support position at which the support section abuts the probe to support the probe when bent in a direction off of the central axis in accordance with a load which is applied to the probe, and subserviently moved with the vibration of the probe. The support section absorbs the vibration transmitted in the probe when the support section is at the support position.

Abstract:
A controller carries out a single outputting phase in which only first electric energy is supplied to an electrode, and transitions the single outputting phase to a simultaneous outputting phase in which the first electric energy and second electric energy are simultaneously output and treated target is denatured due to both of a high-frequency current and treatment energy generated in a functioning element. The controller sets a control pattern relating to the treatment energy in the simultaneous outputting phase, based on an impedance at a certain time point in the single outputting phase and/or a variation with time of the impedance in the single outputting phase.

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.
