Dynamic Input Action Assignment for Surgical Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical navigation systems face challenges in determining user intent for specific actions, such as point acquisition or registration functions, during procedures like arthroscopic surgeries.
Innovation Solution
The method involves dynamically assigning actions to input devices of a surgical instrument based on the state of the surgical system, transitioning between states upon detection of different surgical instruments, and using a processor to execute these assignments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the surgical system uses fixed action assignments for input devices, then the system is simple to operate, but the system cannot adapt to different surgical instruments and procedures
Solution Approach 1:
The system dynamically reassigns actions to input devices based on the detected surgical instrument type and current system state. When a second surgical instrument is detected, the system transitions to a second state and reassigns actions accordingly, making the system adaptable without requiring complex manual reconfiguration
Solution Approach 2:
The system continuously monitors the surgical environment for instrument detection and uses this feedback to automatically transition between states and reassign input device actions, enabling the system to adapt to changing surgical conditions without user intervention
2Adaptability or versatility
If the system dynamically reassigns actions based on instrument detection, then the system is highly adaptable, but the system complexity increases
Solution Approach 1:
The surgical system implements a universal state management framework that handles multiple instrument types and action assignments through a common architecture. The system can transition between different states and reassign actions to the same input devices based on the detected instrument, providing multi-functionality without requiring separate dedicated systems for each instrument type
3Productivity
If the system transitions states automatically upon instrument detection, then the productivity improves, but the reliability may be compromised due to automatic state changes
Solution Approach 1:
The system pre-defines multiple operational states with specific action assignments for different surgical instruments. When an instrument is detected, the system transitions to the pre-configured state appropriate for that instrument, ensuring reliable and efficient operation without requiring real-time decision-making or manual reconfiguration during the procedure

AI summary
A method for dynamically assigning actions to a plurality of input devices of a first surgical instrument connected to a surgical system includes, using one or more computing devices, with the surgical system in a first state, assigning a first action to a first input device of the plurality of input devices. In the first state, the surgical system is configured to cause the first action to be performed in response to the first input device being actuated. The method further includes detecting a second surgical instrument and, in response to detecting the second surgical instrument, transitioning the surgical system to a second state and assigning a second action to the first input device. In the second state, the surgical system is configured to cause the second action to be performed in response to the first input device being actuated.
