Medical Robot Selector Switch for Manual Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical robots face difficulties in releasing the drive control of the arm unit to allow adjustments and settings during procedures, as the location of the release mechanism can be inconvenient and prone to errors due to limited posture and interference from adjacent components.
Innovation Solution
A medical robot with a selector switch integrated on the holding body of the arm unit, allowing practitioners or assistants to easily switch between a controlled state and a manual state, thereby enabling adjustments and settings without the need to move away from the arm unit.

Engineering Contradiction Analysis
1Ease of operation
If the release mechanism is provided on the arm unit, then the drive control can be released to allow adjustments, but the location is inconvenient and prone to errors due to limited posture and interference from adjacent components
Solution Approach 1:
The release mechanism is relocated from the arm unit to the holding body, changing the spatial dimension where the operation occurs. This allows the selector switch to be positioned on the holding body which can be oriented in different directions, providing operational freedom regardless of arm posture and eliminating interference from adjacent components.
Solution Approach 2:
The holding body serves as an intermediary structure that carries the selector switch between the operator and the arm unit. By placing the release mechanism on the holding body rather than directly on the arm unit, the design mediates the control function to a more accessible and error-resistant location.
2Ease of operation
If the selector switch is provided on the holding body, then switching between control states becomes convenient and accessible, but the device complexity increases
Solution Approach 1:
The selector switch is integrated onto the holding body, merging the control function with the existing structural component. This consolidation approach allows the release mechanism to be accessed conveniently while minimizing additional complexity by utilizing the holding body's existing structure rather than adding a completely separate control system.

AI summary
A medical robot includes an arm, a controller that controls driving of the arm, a holding body that is connected to the arm at a connection portion and holds a held body, and a selector switch provided on the holding body for selectively switching between a control state in which the driving of the arm is controlled by the controller and a manual state in which control by the controller is released. The controller performs control of switching between the control state and the manual state based on an operation signal from the selector switch.
