Summary
This study optimized the Taylor spatial frame (TSF) to minimize platform movement during orthopedic procedures. The new method significantly reduces irregular motion, enhancing patient safety and treatment outcomes.
Area of Science:
- Orthopaedic surgery
- Biomechanical engineering
- Robotics
Background:
- The Taylor spatial frame (TSF) is a six-axis external fixator crucial in orthopaedic reconstruction and trauma.
- Irregular platform movement in TSF can lead to complications due to bone and tissue collisions.
Purpose of the Study:
- To minimize irregular platform movement during TSF-assisted orthopaedic procedures.
- To reduce the risk of complications associated with TSF use.
- To enhance the precision and safety of orthopaedic treatments.
Main Methods:
- Integration of kinematics solutions with multi-objective genetic algorithms and ant colony optimization.
- Optimization focused on strut length and order adjustment for the TSF.
- Validation through both simulation and physical experiments of the orthopaedic process.
Main Results:
- Achieved an average offset of less than 1 mm per single adjustment after optimization.
- Reduced overall offset during the entire orthopaedic process by approximately 38.8%.
- Demonstrated significant improvement in platform stability and movement control.
Conclusions:
- The developed method effectively minimizes TSF moving platform offset.
- The optimization ensures orthopaedic accuracy is maintained.
- This approach enhances the safety and efficacy of TSF in orthopaedic applications.
