Robotic surgery has recently made new progress. In a recent experiment, the STAR robot (Smart Tissue Autonomous Robot) was used to complete the operation of suturing the small intestine of the pig by its own vision, tools and wisdom. What's more, in this trial, STAR and a human surgeon simultaneously challenged the task, and STAR did better than the surgeon.
STAR's R&D team never said that robots can soon replace humans on the operating table; but after this test, they have proven that robots are expected to be in the near future, both in surgical technology and in "self-monitoring". Replace humans.
Pediatric surgeon Peter Kim is also a researcher at STAR. In the interview, he did not feel any pressure or threatened. "Although our surgeons are very proud of their own cutting techniques, if the robots can work together, the surgery will be better and safer."
The related papers of this STAR robot have been published in the medical journal Translational Medicine. The researchers wrote a "small intestine suture" procedure for the robot, which is simply to suture a cut small intestine. "It's about the same as repairing rubber hoses," Ryan Decker, a senior engineer on the development team, said. Stitching must be tight and spaced the same to prevent leakage. The STAR robot first performed this experiment on isolated tissues in the laboratory, and then performed live experiments on anesthetized pigs. An experienced surgeon also challenged the same task. By comparison, STAR stitching is more regular and less prone to leakage.
But the robot did help a little. In the entire experiment, 40% of the researchers have provided guidance or help for the robot, such as helping the robot take the line and so on. Another 60% is STAR completely autonomously completed. Researchers don't feel that their help has anything to do with "autonomy"; they think the equipment is fully compliant with the actual surgical scenario. The surgeon can supervise the robot's surgical procedure or share the weight with the robot, allowing the robot to be responsible for a relatively single and cumbersome part. Decker said: "If the robot can replace some parts of the surgery instead of the doctor, let the surgeon have time to go out for a cup of coffee."
In fact, smart machines are now in use in some operations. Surgery such as knee replacement, laser vision and hair transplant can be done to the robot. What these procedures have in common is their goal, such as the leg bones, eyes, head, etc., which can remain motionless during surgery. Soft tissue surgery is much more complicated than this, and it is difficult to hand over to the robot because the smooth, matte tissue in the body moves and is difficult to track.
Health foods contain a certain amount of functional health ingredients, which can regulate the functions of the human body, have specific effects, and are suitable for specific groups of people. General food does not have specific functions, and there is no specific range of people to eat. Health food cannot be directly used to treat diseases. It is a human body mechanism regulator and nutritional supplement.
