In the operating room, after the two left and right coronary arteries were threaded to the predetermined position, the whole threading work was officially completed, and then came the most critical and important part of the whole operation, that is, the anastomosis of the blood vessels.

Compared with ordinary bypass surgery, there are only two vascular anastomotic interfaces, but this time there are dozens of vascular interfaces that need to be anastomotic.

In addition, the entire anastomosis must be sutured flat, without folds or other raised objects, which will become a hotbed for subsequent accumulation of fatty plaque in blood vessels.

Generally speaking, this kind of tiny 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 must not be sloppy.

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

You must know that the blood supply blood vessels of this 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, then this heart tissue will be necrotic due to ischemia.

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

Therefore, this is also one of the difficulties in the overall replacement of coronary arteries in this heart. To put it simply, this cannot be done manually, because the field of view of the thoracotomy is so large, it really cannot accommodate too many people to perform the operation at the same time.

Now, with the help of this medical multi-tentacle surgical robot with 36 tentacles, six surgical teams can perform core operations at the same time, that is to say, it can perform anastomosis of six blood vessels at the same time.

It can still be like this!

this…

I'll go, it's too convenient.

…

For a moment, all the doctors who were watching the live broadcast of the operation couldn't help exclaiming, the live broadcast picture deeply stimulated everyone.

The screen switched to the field of view of a surgical team. The surgical team manipulated the robotic arm to place the original end vessel fracture of the heart and the newly implanted coronary artery vessel fracture on a very small concave-convex anastomosis table, and began to A knife is used to cut the fractures of the blood vessels at both ends, so that they can be spliced ​​together flatly.

Immediately afterwards, a mechanical arm picked up two blood vessels, and then used a transparent semi-solid ointment product to smear the broken blood vessels.

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

The whole process was divided into quick steps, the whole process took about a minute, and a small blood vessel was sutured. Moreover, the stitching density is very fine, which cannot be returned manually.

After the belt was sutured, as the robot pulled the end of the thread closer to take up the thread, the two blood vessels were only sewn together in a circle, and there was no room for a gap, and the transparent semi-solid paste that was just applied on the fracture also penetrated through the gap come out. Immediately afterwards, a mechanical arm reapplied this transparent semi-solid ointment on the vascular anastomosis interface.

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

This is too fast, when did the blood vessel suture operation so quickly. It's not like sewing blood vessels, but trying to sew clothes on a sewing machine.

And the stitching is very pleasantly surprised. Not only is the thread even and fine, but the stitches are also relatively dense. Apart from other things, there are not many doctors in the world who can find such a fine suturing technique. Because even if the human hand is dexterous, there are still errors and mistakes, while the machine can achieve no errors and zero mistakes, which is an advantage.

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

Compared with our manual suturing, this kind of robotic suture surgery has great advantages. It has the advantages of fast speed, high precision, zero error, zero error, regular routing and dense. For example, such a 0.3 cm branch vessel can be sutured with 30 to 40 stitches. This kind of suture density cannot be done manually.

We apply this clear biogel to the anastomoses of blood vessels before and after they are sutured. This biogel has the effect of sealing and promoting wound healing, and it is completely biomaterial without side effects, and it will automatically dissolve and metabolize within a few days without leaving any residue.

The reason why we apply this biological gel is, of course, to seal the blood vessels and avoid the occurrence of blood vessels and blood leakage. On the other hand, this biological gel is also helpful for the recovery of the wound, and it has another advantage, that is, it can eliminate the scar of the wound, so that it can ensure that the seams of the entire blood vessel are flat enough to avoid unevenness in the blood vessel The unevenness leads to the accumulation of fat blocks in the blood vessels~www.readwn.com~, resulting in atherosclerotic stenosis and stasis at the seams of blood vessels. "

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

As the seam of this blood vessel got closer and was clearly displayed in front of everyone, many experts who were watching the live broadcast were not calm. The stitching is impeccable, it's really like the difference between hand stitching and machine stitching on a garment.

This has made many experts who boast that they have a brief introduction in the field of vascular anastomosis and who are the top suture experts feel a deep sense of crisis. In the face of such equipment and such technology, how can they show off their proud technology.

Just as everyone was stunned, the suturing operation of the entire tubular artery was more than half completed. This kind of progress was beyond everyone's expectation. The vascular anastomosis process, which was considered the most complicated and time-consuming by everyone, is so simple and easy with the help of this medical multi-tentacled surgical robot. They completely lamented that with the rapid development of technology, I am afraid that if this continues, they will really lose their jobs.
