Robotic stabilization that assists cardiac surgery on beating hearts

Area of Science:

• Robotics in Surgery
• Cardiovascular Surgery
• Medical Engineering

Background:

• Minimally Invasive Direct Coronary Artery Bypass (MIDCAB) surgery is challenging due to the need for high precision on a moving target (beating heart).
• Current surgical techniques demand exceptional manual dexterity and concentration from surgeons.
• Organ motion during surgery can lead to inaccuracies and complications.

Purpose of the Study:

• To develop and evaluate a novel surgical robot system designed to compensate for organ motion during beating heart surgery.
• To enhance the precision and safety of Minimally Invasive Direct Coronary Artery Bypass (MIDCAB) procedures.
• To provide surgeons with a tool that mitigates the challenges of operating on a dynamic surgical field.

Main Methods:

• Development of a motion-canceling surgical robot system.
• Integration of three core technologies: visual synchronization, motion synchronization, and master-slave control.
• Validation of the prototype system's effectiveness through in-vivo experimentation.

Main Results:

• The prototype motion-canceling robot system demonstrated its effectiveness in compensating for organ motion during in-vivo experiments.
• The system successfully integrated visual and motion synchronization with master-slave control.
• Preliminary results indicate a potential for improved surgical accuracy in beating heart procedures.

Conclusions:

• The proposed surgical robot system shows promise for overcoming the challenges of operating on beating hearts.
• Motion compensation technology is crucial for advancing minimally invasive cardiac surgery.
• Further research and development are warranted to translate this technology into clinical practice.
