US 2026/0198996 A1 · ENERGY TREATMENT TOOL AND TREATMENT SYSTEM

Abstract

An energy treatment tool includes: a grip to be held by an operator; a lever that is provided in a state of being exposed to an outside of the grip, the lever being configured to move in response to a changing operation by an operator, the changing operation being for changing an output state of energy; an electric switch that is arranged inside the grip the electric switch being configured to generate a signal for changing an output state of the energy; and a driver that is installed inside the grip such that the driver is rotatable about an axis intersecting an axis along a longitudinal axis correspondingly to movement of the lever, the driver being configured to switch the electric switch between a contacting state and a noncontacting state.

Dependent claims

An energy treatment tool, comprising:

an end effector configured to apply energy to treat a living tissue;
a grip to be held by an operator;
a first lever provided in a state of being exposed to an outside of the grip, the first lever being configured to move in response to a changing operation by an operator, the changing operation being for changing an output state of the energy at the end effector;
a second lever provided in a state of being exposed to the outside of the grip, the second lever being configured to move in response to the changing operation;
and
a driver that is movably attached, together with the first lever and the second lever, in the grip, the driver being configured to move the first lever and the second lever in association with each other in response to the changing operation on the first lever or the second lever.
