Surgical Robot Instrument Selection Display for Clear Tool Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical robots do not allow operators to easily determine which medical instrument is selected and which switch corresponds to its movement, leading to confusion during operations.
Innovation Solution
A surgical robot with a display unit that shows the selection status of medical instruments, using marks or letters overlapped on the instruments, and operated state detection units to display operation contents, allowing operators to easily identify selected instruments and their corresponding switches without diverting attention from the surgical site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a common input portion is used to operate multiple medical instruments, then the device complexity is reduced, but the operator cannot easily judge which medical instrument has been selected and which switch corresponds to which movement
Solution Approach 1:
The display unit provides visual feedback by showing marks and letters that indicate which medical instrument is currently selected and which switch corresponds to which instrument movement. This feedback mechanism resolves the information loss caused by using a common input portion for multiple instruments.
Solution Approach 2:
The display unit acts as an intermediary between the common input portion and the multiple medical instruments, providing visual information about the selection status and switch correspondence without adding physical complexity to the input portion itself.
2Loss of information
If operation directions of all medical instruments are displayed at the same time, then complete information is provided, but the operator cannot easily identify the selected instrument among multiple displays
Solution Approach 1:
Different visual characteristics (marks and letters) are applied to different instruments in the display. The selected instrument is distinguished by specific visual properties, allowing the operator to easily identify it among all displayed instruments while maintaining complete operation direction information.
Solution Approach 2:
The display unit uses visual differentiation through marks and letters to distinguish the selected instrument from non-selected instruments. This visual change helps operators quickly identify the active instrument without obscuring other operation directions.
