Abstract: A perfusion state detection method includes: driving a liquid feeding pump configured to supply a liquid via a liquid feeding conduit inserted into a living body; driving a suction pump configured to discharge the liquid via a suction conduit inserted into the living body; obtaining a distance, on a plane indicating a relation between any two values of a drive output to the suction pump, a flow rate of the liquid flowing through the conduit, and a pressure in the conduit, between a coordinate on the plane of the two values in a perfusion state at normal time of the conduit and a coordinate on the plane of the two values actually measured; detecting abnormality of the perfusion state of the conduit based on whether the distance exceeds a threshold; and controlling a flow of the liquid in the conduit based on a detection result of the perfusion state.

Abstract: An energy treatment instrument includes: a first jaw including a first holding surface including a first end region, a second end region and a first reference position; a second jaw including a second holding surface including a third end region, a fourth end region and a second reference position; a first electrode disposed in the first end region; and a second electrode disposed in one of the second end region and the fourth end region, electrical current being applied between the first electrode and the second electrode. In a state in which the first holding surface and the second holding surface face each other, a clearance between the first holding surface and the second holding surface is continuously changed toward the first reference position and the second reference position and a clearance between the first reference position and the second reference position is greatest.

Abstract: A medical power supply includes a medical instrument and a guide tube. The power receiving member is arranged radially outside the insertion portion, and when the insertion portion is inserted into the guide tube to a predetermined length such that the power transmitting member and the power receiving member are close to each other, a power transmitting side proximal end surface of the power transmitting member and a power receiving side distal end surface of the power receiving member face each other in an axial direction of the insertion portion and are in a positional relationship such that wireless power supply is possible.
