Robotic computer-assisted telemanipulation enhances coronary artery bypass

Area of Science:

• Cardiovascular Surgery
• Minimally Invasive Surgery
• Robotic Surgery

Background:

• Totally endoscopic coronary artery bypass grafting (TECAB) requires precise anastomosis.
• Advancements in surgical technology are crucial for improving TECAB outcomes.

Purpose of the Study:

• To evaluate a novel computer-assisted telemanipulation robot for performing endoscopic coronary artery anastomosis.
• To compare robotic-assisted anastomosis with conventional and other endoscopic techniques.

Main Methods:

• On-bench porcine coronary artery anastomoses were created using five different techniques.
• Groups included direct visualization with conventional instruments, endoscopic 3D visualization with endoscopic instruments, direct visualization with endoscopic instruments, 3D endoscopic visualization with conventional instruments, and telemanipulation robotic with 3D endoscopic visualization.
• Anastomoses were assessed for time, quality, technical difficulty, and patency.

Main Results:

• Anastomotic time was significantly longer in endoscopic groups without robotic assistance compared to robotic-assisted and direct visualization with conventional instruments.
• Graft patency was comparable across all tested groups.
• Telemanipulation robotic system showed promising results in terms of efficiency and technical feasibility.

Conclusions:

• Telemanipulation technology may enhance the performance of totally endoscopic coronary artery anastomosis.
• The Intuitive telemanipulation system offers comparable facility and time to conventional anastomosis under direct vision.
• Robotic assistance holds potential for improving the precision and efficiency of minimally invasive cardiac surgery.
