Optical Shape Sensing Fiber for Catheter Event Triggering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical procedures, interventional elongated devices like catheters require operators to put down the device or ask for assistance to trigger events, such as tagging landmarks, due to the need for two hands to operate both the device and additional system controls, which is inefficient and disrupts workflow.
Innovation Solution
A medical system equipped with an optical shape sensing fiber that allows users to manipulate the device to trigger events without additional interfaces, using detection and analysis units to recognize specific manipulations, such as deformations or taps, applied to the device to control other system components, enabling single-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If additional control interfaces are provided on the medical device, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The medical device monitors and detects its own manipulation actions through integrated sensors that sense the manipulation action on the manipulation section, eliminating the need for separate control interfaces or additional operators to trigger events
Solution Approach 2:
The manipulation section serves dual functions: it is both the control interface for triggering events and the functional section of the medical device, allowing the device to perform multiple operations without adding separate control mechanisms
2Productivity
If the medical device is manipulated with one hand, then productivity is improved, but ease of operation worsens due to lack of additional hand for control
Solution Approach 1:
The control function is merged with the manipulation function by integrating sensors directly into the manipulation section, allowing the same hand that manipulates the device to also trigger events through the manipulation itself
Solution Approach 2:
Sensors act as intermediaries that detect the manipulation action applied by the user and automatically translate it into event triggering, eliminating the need for a second hand or operator
3Ease of operation
If multiple operators are used to control the system, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system automatically detects and responds to manipulation actions through integrated sensors, eliminating the need for multiple operators or assistants to control the medical device
Solution Approach 2:
The sensors provide real-time feedback about the manipulation action applied to the manipulation section, enabling the system to automatically determine when an event should be triggered based on the detected action

AI summary
The present invention relates to a medical system using an interventional elongated medical device having an optical fiber configured for optical shape sensing of the medical device. The system comprises a detection unit configured to detect a confined manipulation section along the medical device for manipulation by a user without an interaction interface arranged on the medical device and an analysis unit configured to analyze a user manipulation applied to the manipulation section based on optical shape sensing of the medical device in the manipulation section and to trigger an event in the medical system, if the analysis unit identifies the user manipulation in the manipulation section as a specific manipulation associated with the event to be triggered.
