Summary
Robot-assisted surgery, Robossis, offers an intuitive solution for femur fracture repair, reducing malalignment and X-ray exposure. This leader-follower system precisely tracks surgeon commands, enhancing surgical outcomes.
Area of Science:
- Robotics in Medicine
- Orthopedic Surgery
- Surgical Technology
Background:
- Femur fracture surgery faces challenges including malalignment and radiation exposure.
- Robot-assisted surgery presents a promising alternative to conventional techniques.
Purpose of the Study:
- To introduce Robossis, a novel leader-follower robot-assisted system for femur fracture surgery.
- To develop and evaluate control architectures addressing kinematic mismatch and motion transfer.
Main Methods:
- Development of a 7-DOF haptic controller and a 6-DOF surgical robot (Robossis).
- Implementation of a control architecture with motion and haptic rendering pipelines.
- Experimental evaluation of motion transfer accuracy and kinematic mismatch resolution.
- Cadaveric testing during a mock femur fracture surgery.
Main Results:
- Robossis achieved high trajectory adherence with average translational error of 0.32 mm and rotational error of 0.07°.
- Haptic rendering pipeline effectively constrained user hand movement within robot's joint limits.
- Cadaveric testing demonstrated Robossis as an intuitive solution for femur fracture surgery.
Conclusions:
- The Robossis system offers precise and intuitive control for robot-assisted femur fracture surgery.
- This technology has the potential to improve surgical accuracy and reduce risks associated with conventional methods.
