A robot that operates automatically in place of a doctor is under development, and the movie in the state of surgery actually looks like this

Since it is a living cell and soft, it has been extremely difficult to operate with a robot so far, and robotic surgery was criticized as "less secure than human surgery". However, due to the development of new technologies, robots boasting the same success rate as human surgery are made, and the state of actual surgery is published on YouTube.

The state of the robot which performs automatic suturing of the operation can be confirmed from the following.

Robot Performs Successful Surgery On Pig | NBC News - YouTube


The newly developed automatic surgical robot is "Smart Tissue Autonomous Robot (STAR)What is called. We will use 3D models to map the sewn portions of the cells and automatically perform suturing. The actual sewing test was not done so far, but this time a new test was done using pig intestines to "restore two pieces to one tube".


Looking at the whole robot is like this.


Robotic arm is a German industrial robot maker ·KUKAOf things. The arm part is controlled 7 axes, and the tip is equipped with a device for suturing. It is equipped with a force sensor (load sensor) that sends feedback on how strongly the needle moves with the movement of the arm.

The computer behind the robotic arm displays while tracking the sewed place. Basically, we decide where to sew from the "best" surgery data done in the past, but you can change the sewing location manually as needed. In past tests we have succeeded in automating 60% of the whole, researchers said, "We are kind of like parents who watch the children who started walking and carefully watching them," careful It is an attitude.


Looking from another angle it is like this. Gashon, and the part passed through the suture hold down the intestines of the pig ... ...


It seems like a sewing machine like sewing up, lifting it up.


In the test, human laparotomy / endoscopic surgery / surgery assistance robot "Da Vinci"The surgery using STAR was compared with the finish of the operation by STAR. The stitching of the suture is "incompatible" and the more seamed and weakly sutured the part is, the more "leakage" will occur, but the surgical mark of STAR is more consistent than the other surgical traces I was able to sew it. Although it seems that the speed will be slower than human surgery in order to proceed with caution, the strength of the suture trace seems to be about the same degree of completion as human surgery. Although Da Vinci has been approved by the FDA as a robot that performs surgery in 2000, despite the extremely expensive robot, the disadvantage that the complication rate is the same as that when a human operates it is was.

The failure rate of ordinary surgery is less than 1%, and it is necessary to further lower the failure rate when putting STAR into practical use, and it is indispensable to prove safety by further experiments. According to researchers, it seems that it will take ten years for STAR to actually be active in hospitals.
