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.
Claims19
An energy treatment tool, comprising:
- a grip and a movable trigger portion connected to the grip on a distal side of the grip, the grip being configured to be held by an operator;
- a sheath attached to the grip and extending along a second axis;
- a lever that is provided on a lateral side surface of the grip, the lever being configured to rotate about a first axis that intersects the second axis in a three-dimensional manner, in response to a changing operation by an operator, the changing operation being performed for changing an output state of energy;
- a switch element that is arranged inside the grip, the switch element being configured to generate a signal for changing an output state of the energy;
- and
- a switch supporting portion that is arranged entirely inside the grip such that the switch supporting portion is configured to rotate about the first axis that intersects the second axis, the switch supporting portion being configured to move in response to a movement of the lever, the switch supporting portion being configured to switch the switch element between an electrically connected state and an electrically disconnected state.
