BACKGROUND
Surgical robot systems have been used in laparoendoscopic single-site surgery (LESS) to improve patient outcomes. A magnetic anchoring surgical robot system for LESS can effectively extend the operation space.
METHODS
A robot system based on visual servo control for LESS is proposed. It includes a magnetic anchoring robot and a control subsystem, in which an uncalibrated visual servo control method obtains an accurate positioning capability of the robot for LESS.
RESULTS
The results of the simulation and the tissue experiment show that the robot system can successfully accomplish the expected control functionalities for LESS. The average positioning error of the proposed system is 1.622 mm.
CONCLUSION
The magnetic anchoring robot system is able to implement the autonomous positioning of its end-effector through the proposed control approach according to experimental results.
