"Okay, you give it a try. Don't use your eyes; just let go, Professor Xu will always be watching."
The patrolling nurse was preparing to equip everyone with head-mounted microscopes, but Yang Ping said there was no need for microscopes:
"Prepare the thoracoscope and its instruments!"
Yang Ping turned his head to look below, and the thoracoscope downstairs wasn't ready yet.
"Performing with a thoracoscope?" The patrolling nurse looked at Professor Xu in surprise, to confirm if this was for real.
Professor Xu was also completely baffled: "Thoracoscope?"
Common coronary artery bypass grafting could be performed with a thoracoscope, but this case required vascular anastomosis with a vein, and since veins have thin walls and the heart beats violently, the long-arm instruments of the thoracoscope are hard to control and fundamentally incapable of such delicate operations. Any mistake would tear the vessels apart.
