"What Senior Sister Xie just talked about was TECAB, a completely endoscopic robot-assisted coronary artery bypass grafting." Mi Wenlin repeated and translated what Senior Sister said word for word, his tone revealing a sense of surprise.
A group of junior and senior students who were following them had done their homework privately, so they knew that currently the only robot in the world that could make TECAB was from Company B, and TECAB was Company B’s unique skill.
If you can thoroughly understand the meaning of the above words, you will understand why Mr. Ren did not ask about TECAB at the beginning, but only emphasized beating heart surgery.
Here we have to mention another famous robot company Z, which is as famous as Company B in the world. The robots of Company Z can also perform MIDCAB, a robot-assisted minimally invasive direct coronary artery bypass surgery. As the name suggests, the robot only performs part of the surgery and does not perform a full endoscopic surgery.
Based on this, we can infer how difficult TECAB is.
What is so difficult about TECAB? Let’s compare it to the thoracoscope, the predecessor of surgical robots.
When using thoracoscopic coronary artery bypass grafting, many doctors also prefer to use thoracoscopic surgery to assist in some surgeries rather than full thoracoscopic surgery.
At which stage of the operation do these doctors use laparoscopes to assist and at which stages do they not?
We have mentioned before that the best "bridge" in the human body for coronary artery bypass grafting is the internal mammary artery. In traditional surgery, the internal mammary artery needs to be harvested through a midline incision and splitting of the sternum. Laparoscopic technology, thoracoscopy or surgical robots have many advantages over traditional surgery when harvesting the internal mammary artery. It does not require splitting of the sternum, which is beneficial to patients and convenient for doctors.

Therefore, laparoscopic technology assistance is the primary focus in this part of the surgical procedure.
Why don’t doctors like to use laparoscope to complete the following bypass surgery?
The heart is an irregular arc-shaped sphere, which can be simply summarized as an egg. Is it easier to sew blood vessels on the arc-shaped surface of a bouncing "egg" under direct vision? Or is it easier to operate under the difficult illumination of a "long stick" and adjust it back and forth under the "mirror"?
Obviously the former is easier.
Not to mention that bypass surgery can now also be done with small incisions, which will not leave big scars for patients and will be convenient for doctors.
If so why pursue full endoscopic surgery?
Fully endoscopic surgery can magnify the surgical field of view to several times that of traditional surgery, allowing doctors to perform surgery in an extremely delicate and minimally invasive manner. This is impossible with direct vision surgery, as direct vision surgery will inevitably require doctors to use "thick" fingers to operate.
It makes sense to design the robot well so that doctors can perform TECAB.
If their team can really achieve this, their technology will definitely be on par with that of Company B and be the best in the world.
He, the big boss, didn't dare to even think about such a beautiful dream. His first goal was at most to catch up with the second-ranked Z company and become a MIDCAB.
"You said we can choose more complicated surgical cases?" Ren Zhe Lun was sure if he heard it wrong.
Junior Sister Wanwan, the superwoman, told him that we can surpass Company B and make more complex TECAB?!
The surroundings were so quiet that you could hear a pin drop. A large group of people held their breath, and their mentality was no different from that of Ren Da Lao, too shocked to express themselves.
Xie Wanying didn't have time to answer Senior Brother Ren's question.
The cell phone is ringing.
Ren Zhelun took out his cell phone from his white coat pocket.
His boss, Mr. Zhang, called him and said, "Bring Xie Wanying to my office. Director Fang brought a medical record."
