In the operating room, after the two left and right coronary arteries were routed to the predetermined position, the entire route work was officially completed. Next came the most critical and important part of the entire operation, which was the anastomosis of the blood vessels.

Compared with ordinary bypass surgery, which only has two vascular anastomoses, this time there are dozens of vascular anastomoses that need to be anastomosed. These blood vessels need to be sutured very carefully to ensure that there will be no blood leakage at the vascular anastomoses.

In addition, the entire anastomosis interface must be sutured flat, without wrinkles or other raised objects, which will become a breeding ground for the subsequent accumulation of fat plaques in the blood vessels.

Generally speaking, this kind of small blood vessel anastomosis needs to be performed under a microscope, and it also needs to be performed by experienced doctors. Although the entire anastomosis process requires speed, it cannot be sloppy.

It already takes a long time for ordinary doctors to complete one or two blood vessel anastomoses, but now there are dozens of such blood vessels, and it may be difficult to complete it in a short time by manpower alone.

You must know that the blood supply blood vessels of the heart tissue have been cut off at this time. If these blood vessels cannot be connected and provide blood supply within a certain period of time, the heart tissue will become necrotic due to ischemia.

Therefore, time is of the essence. The longer the delay, the worse the condition of the heart tissue will be, and the worse the subsequent functional recovery will be.

Therefore, this is also one of the difficulties in this whole coronary artery replacement surgery. Simply put, this cannot be done manually, because the field of view of thoracotomy is so large that it really cannot accommodate too many hands to perform the surgery at the same time.

Now, with the help of this thirty-six-tentacled medical multi-tentacle surgical robot, six surgical teams can perform simultaneous core surgeries, which means that it can perform six blood vessel anastomosis surgeries at the same time.

It can still be like this!

this……

I'll go, this is too convenient.

…

All the doctors who were watching the live broadcast of the operation couldn't help but exclaimed. The live broadcast deeply stimulated everyone.

The scene switched to the field of view of a surgical team. This surgical team controlled the robotic arm to place the original terminal blood vessel fractures of the heart and the newly implanted coronary artery blood vessel fractures on a very small concave and convex anastomosis table. Use a knife to cut the broken ends of the blood vessels at both ends so that they can be spliced ​​together smoothly.

Immediately afterwards, a robotic arm was seen picking up two blood vessels, and then using a transparent semi-solid ointment product to smear the fractures of the blood vessels.

Immediately afterwards, the two blood vessels were placed on the anastomosis table, and the two sides were fixed by robotic arms with a certain gap in the middle. The operator began to control the equipment, and saw a mechanical arm begin to extend into the air strike between the two blood vessels, and then began to walk left and right. The whole process is fast and smooth, just like a sewing machine running threads on clothes.

The whole process is very quick, and it only takes about a minute. At this point, a small blood vessel is sutured. Moreover, the density of stitching is very fine, which cannot be done manually.

After the tape was sutured, as the robot pulled the thread closer to take up the thread, the two blood vessels were merely sewn in a circle, leaving no room for any gaps, and the transparent semi-solid paste just applied on the fracture also seeped through the gaps. come out. Immediately afterwards, a robotic arm came to re-apply this transparent semi-solid ointment to the vascular anastomosis interface.

In this way, the anastomosis of the blood vessel is completed.

This is too fast. When did the blood vessel suturing surgery become so fast? This is not like sewing blood vessels, but like sewing clothes on a sewing machine.

And the stitching is very surprising. The stitching is not only even and detailed, but also the stitches are relatively dense. Not to mention other things, there are only a few doctors in the world who can master such fine suturing techniques. Because even if human hands are dexterous, they still have errors and mistakes, but machines can achieve no errors and zero mistakes, which is an advantage. new

Director Tong, who had been paying attention to the suturing situation, also smiled at this time, and then smiled at the camera and said: "This medical intelligent surgical robot has automatic suturing technology. Our doctors can set relevant parameters according to the different suture tissues. , this robot can perform related fine suture surgeries according to our requirements.

This kind of robotic suturing surgery has great advantages over our manual suturing. It has the advantages of fast speed, high precision, zero error, zero mistakes, regular routing, and denseness. For example, a branch blood vessel of 0.3 centimeters can be sutured with thirty to forty stitches. This suture density cannot be accomplished manually.

We will apply this clear biogel to the anastomoses of the blood vessels before and after they are sutured. This biogel has the effect of sealing and promoting wound healing, and it is completely biomaterial, has no side effects, and will automatically dissolve and metabolize cleanly within a few days without leaving any residue.

The reason why we apply this biogel is of course to seal the blood vessels and avoid blood leakage behind the blood vessels. On the other hand, this biogel also helps with wound recovery, and it also has a major advantage, that is, it can eliminate the scars of the wound. In this way, it can ensure that the seams of the entire blood vessels are flat enough and avoid bumps and convexities in the blood vessels. Unevenness causes fat in blood vessels to accumulate here, resulting in atherosclerotic stenosis and siltation at blood vessel joints. "

Please see, this is the blood vessel we anastomosed. As he spoke, Director Tong controlled a mechanical tentacle and pointed the camera at a blood vessel that had been anastomosed.

As the seam of this blood vessel became closer and closer, clearly appearing in front of everyone, many experts who were watching the live broadcast became uneasy. The entire stitching interface is impeccable, it's really like the difference between hand-sewn stitching on clothing and sewing machine-sewn stitching.

This has made many experts who claim to be experts in the field of vascular anastomosis and self-proclaimed leaders in suturing feel a deep sense of crisis. In the face of such equipment and technology, how can they take advantage of the technology they are proud of.

While everyone was stunned, most of the suturing operation of the entire tubular artery had been completed. This progress was unexpected by everyone. The vascular anastomosis process, which originally seemed to everyone to be the most complicated and time-consuming, has become so simple and easy with the help of this medical multi-tentacle surgical robot. This has really subverted many people's perceptions and also made many doctors They completely lamented that with the rapid development of technology, I am afraid that if this continues, they will really lose their jobs.
