Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgery navigation systems face challenges in accurately updating the position and posture information of surgical machines, such as robotic arms, when they are moved or repositioned during surgery, leading to potential inaccuracies and increased surgery duration.
Innovation Solution
A system and method utilizing a sensing element, a displacement and/or angle sensing element, and a processor to detect changes in the position and posture of surgical machines and their marker modules. This system generates coordinate and displacement/angle signals, which are used to create a transformation matrix to determine if the original position and posture information needs to be updated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the surgical machine and/or marker module are moved to change the sensing path of the sensor to avoid blocking, then the sensing path blocking is avoided, but the surgery navigation system cannot detect the movement and the position and posture information becomes inaccurate
Solution Approach 1:
The patent implements a feedback mechanism where the sensor continuously detects the marker module's position and the processor compares it with stored reference data. When movement is detected, the system automatically updates the position and posture information, creating a closed-loop feedback system that maintains accuracy despite machine movement.
Solution Approach 2:
The patent uses a marker module as a temporary, easily replaceable reference object. The marker module can be quickly repositioned or replaced if blocked, and the system automatically detects and adapts to its new position through the sensing element, treating it as a consumable reference rather than a permanent fixed component.
2Ease of operation
If the surgical machine is repositioned during surgery to improve accessibility, then the ease of operation is improved, but the time required for surgery navigation increases due to inability to detect position changes
Solution Approach 1:
The patent ensures continuous detection and updating of position and posture information throughout the surgery. The sensor continuously tracks the marker module, and the processor continuously updates the navigation data, eliminating interruptions and maintaining uninterrupted surgical navigation even as the machine is repositioned.
Solution Approach 2:
The system performs self-updating of position and posture information automatically without requiring manual intervention. When the surgical machine moves, the sensor detects the change and the processor automatically recalculates and updates the navigation data, making the system self-correcting and eliminating time-consuming manual recalibration.
3Measurement precision
If manual updating of position and posture information is performed after moving the surgical machine, then the position accuracy can be maintained, but the surgery duration increases due to manual intervention requirements
Solution Approach 1:
The system automatically detects movement through the sensor and autonomously updates position and posture information through the processor without requiring any manual intervention. The transformation matrix is automatically calculated and applied to update the navigation data, making the entire process self-service and eliminating manual updating steps.
Solution Approach 2:
The patent replaces manual mechanical updating procedures with an automated optical sensing and computational system. Instead of manually measuring and inputting position data, the sensor optically detects the marker module position and the processor computationally updates the navigation information, substituting automated electronic systems for manual mechanical operations.
