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.
Core Innovation
The invention relates to an energy treatment tool and a treatment system that apply energy output to an end effector. The tool includes a grip configured to be held by an operator, and a lever provided on a lateral side surface of the grip. The lever rotates about a first axis that intersects a second axis in a three-dimensional manner in response to a changing operation by an operator for changing an output state of energy.
An electric switch element is arranged inside the grip and is configured to generate a signal for changing an output state of the energy. A switch supporting portion is arranged entirely inside the grip and rotates about the first axis intersecting the second axis. The switch supporting portion moves in response to movement of the lever and switches the switch element between an electrically connected state and an electrically disconnected state.
A controller/treatment system controls energy delivery based on switch-detected operations, including switching between ultrasound+HF and HF-only modes and changing an output state. The disclosure further includes mechanical and electrical structures for a third switch mechanism supported by a base unit, including configurations that provide tactile/vibration feedback to prevent erroneous switching and electrical contact arrangements for electrode terminals and transducer outputs.
Claims Coverage
The independent claim covers an energy treatment tool having a grip-held body with an internal switch mechanism actuated by a lever that changes energy output state by switching a switch element between electrically connected and electrically disconnected states. Based on the provided claim set, there is one independent claim (clm-00001).
Lever-rotated internal switch supporting portion for energy output state
A lever provided on a lateral side surface of the grip rotates about a first axis intersecting a second axis in response to a changing operation by an operator for changing an output state of energy, where a switch supporting portion arranged entirely inside the grip rotates about the first axis and moves in response to movement of the lever.
Internal switch element generating signal for electrically connected/disconnected switching
A switch element arranged inside the grip generates a signal for changing an output state of the energy, and the switch supporting portion switches the switch element between an electrically connected state and an electrically disconnected state.
The claim coverage is centered on internal, grip-contained switching: the operator’s lever rotation about a 3D-intersecting axis drives a switch supporting portion that moves to switch an internal switch element between electrically connected and electrically disconnected states to change an energy output state.
