Summary
This study integrates a cooperative robotic arm into computer-assisted orthopedic surgery, enhancing surgeon interaction. A novel singularity handling method ensures precise robotic arm movements during surgery.
Area of Science:
- Robotics
- Orthopaedic Surgery
- Medical Technology
Background:
- Ongoing research on integrating navigated cooperative robotic arms into computer-assisted orthopaedic surgery.
- Focus on seamless system integration that complements, rather than replaces, the surgeon's role.
Purpose of the Study:
- To improve haptic operating modes for interactive robot guidance in surgery.
- To address technical challenges in robotic arm control during orthopaedic procedures.
Main Methods:
- Utilizing virtual fixtures to constrain robot motion based on pre-operative plans.
- Investigating robust methodologies for managing singular arm configurations.
Main Results:
- A new method for handling singularities is proposed, outperforming the damped-least-squares method.
- The novel method ensures no deviation of the robot's end-effector from the virtual fixture path.
Conclusions:
- A solution is presented for maintaining high performance of robotic arms at singularity configurations.
- This advancement supports precise and reliable robotic assistance in orthopaedic surgery.
