A Method to Reduce Tension Differences in Pull/Push Manipulation for a Robot in Fluorescence Emission-Guided Surgical...

Area of Science:

• Robotics
• Surgical Technology
• Medical Imaging

Background:

• Fluorescence-guided microscopy enhances cancer surgery monitoring.
• Manipulator control is key for precise observation direction.
• Minimizing looper tension errors is critical for accuracy.

Purpose of the Study:

• To present a method for minimizing looper tension error in surgical microscopes.
• To improve manipulator stability and reduce error rates.
• To enhance visualization during cancer surgery.

Main Methods:

• Inserting a looper between manipulator stands to equalize tension.
• Ensuring constant stress for stable manipulator movement (left/right, up/down).
• Implementing a method to minimize looper tension differences.

Main Results:

• Reduced tolerance for looper tension differences (angle and tension).
• Achieved output closely matching input looper tension angle (e.g., 50° input).
• Measured response tolerance of ±49.98%, yielding a low error rate of 0.02%.

Conclusions:

• A novel method minimizes manipulator looper tension error in robot-based microscopes.
• Stable manipulator operation with minimal error is achieved.
• Enables 3.986x magnification for detailed close-up observation during surgery.
