Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy treatment tools lack efficient mechanisms for operators to easily and safely change energy output states during medical procedures, particularly in applications involving ultrasound and high-frequency energy, which can complicate surgical operations.
Innovation Solution
An energy treatment tool with a lever mechanism exposed outside the grip, an electric switch inside the grip, and a driver that rotates to switch energy states, allowing for controlled changes in energy output modes, including ultrasound and high-frequency energy, through a controller system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If push buttons are provided on both side surfaces of the grip for changing energy output state, then the operator can change energy output, but the structure becomes complex and the risk of tool damage increases
Solution Approach 1:
The patent combines multiple push buttons into a single lever mechanism. The lever has multiple positions that correspond to different energy output states, merging the function of multiple switches into one integrated control element. This reduces structural complexity while maintaining the ability to change energy output states.
Solution Approach 2:
The lever serves multiple functions: it acts as both the operating mechanism and the switch actuator. By making the lever rotatable about an axis intersecting the longitudinal axis, it can selectively engage different contacts to achieve multiple energy output states, providing multi-functionality in a single component.
2Reliability
If multiple push buttons are provided for changing energy output state, then energy control is possible, but the ease of operation deteriorates due to complex structure
Solution Approach 1:
Multiple push buttons are merged into a single lever with multiple positions. This consolidation simplifies the operator's task to a single rotational motion rather than requiring precise pressing of multiple buttons, thereby improving ease of operation while maintaining reliable energy output control.
Solution Approach 2:
The lever is designed to be rotatable about an axis intersecting the longitudinal axis, allowing dynamic movement between different positions. This rotational capability provides a more intuitive and easier operation compared to static push buttons, while each position maintains reliable contact for energy output control.
3Ease of operation
If a lever mechanism is provided outside the grip for changing energy output, then ease of operation improves, but the device complexity increases
Solution Approach 1:
The lever mechanism outside the grip is merged with the driver inside the grip through a unified rotational axis. The lever's rotation directly drives the switching mechanism, combining the external operating element with the internal switching mechanism into an integrated system, reducing overall complexity.
Solution Approach 2:
The driver acts as an intermediary mechanism that translates the lever's rotational movement into switch actuation. This intermediary component simplifies the connection between the external lever and the internal electric switch, reducing the complexity of direct mechanical coupling while maintaining ease of operation.

AI summary
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.
