摘要

A treatment system includes a guide component that is used to insert a treatment tool into a body cavity, a tilt sensor that is provided in the guide component and detects an angle of inclination of the treatment tool that has been inserted inside the guide component, an insertion amount sensor that is provided in the guide component and detects an amount that the treatment tool has been inserted inside the guide component, a switching device that switches an observation range of images of an interior of the body cavity that are acquired by an observation device that has been introduced into the body cavity and are then displayed on a display unit, and a system control unit that drives the switching device based on information about the angle of inclination and insertion amount of the treatment tool.
