Abstract: A treatment system includes: a treatment instrument configured to cut living tissue in a liquid; an endoscope configured to capture an endoscopic image including an image of the treatment instrument and an image of the living tissue; a support data storage configured to store, as support data to support a cutting treatment, at least one of data regarding a posture of the treatment instrument and image data on a location of a treatment section of the treatment instrument; a support data generator configured to generate support data to be displayed on a display based on the support data stored; a controller configured to control the display to display the endoscopic image; and a turbidity detector configured to detect a degree of cloudiness of the liquid.

Abstract: A treatment system includes: a treatment instrument for cutting living tissue in a liquid; and a controller for performing control, prior to cutting the living tissue with the treatment instrument, to suppress reduced visibility of a treatment area due to turbidity in the liquid caused by the cutting of the living tissue based on preparation information regarding cutting preparation for the treatment instrument.

Abstract: A surgical system includes a treatment tool device that performs a treatment on a biological tissue in a liquid. The system includes a detector that detects turbidity information regarding turbidity in the liquid occurring due to the treatment tool device, and a controller configured to control the surgical system based on a detection result of the detector to reduce turbidity by controlling the surgical system in response to the detection result indicating an occurrence of turbidity in the liquid.
