Surgical machine doctor "fencing" is counterproductive and prolongs operation time
October 26, according to foreign media Telegraph report, a recent study shows that human doctors still perform better than "machine doctors." Compared to robots, human doctors have to complete the operation with shorter time and the error rate is not high.
Since the launch of the first "machine doctor" in the UK ten years ago, the implementation of robotic surgery has continued to climb. Whether in prostatectomy, cystectomy, nephrectomy, or tumor resection, surgical robots have always played an increasingly important role.
According to people’s common understanding, surgical robots are sure to be more precise, more skilled, and faster than human doctors, but a recent study has revealed a diametrically opposite conclusion: for patients, surgery Not only does the doctor's "fencing" not increase the therapeutic effect on them, but it will also make the operation longer.
Researchers at Stanford University School of Medicine who led the study collected data on 25,000 surgeries performed at 416 hospitals in the United States between 2006 and 2012.
They found that of all patients undergoing minimally invasive nephrectomy by a human doctor, only 28% experienced more than 4 hours of surgery. In contrast, nearly 46% of all patients undergoing "machine doctor" surgery have spent more than 4 hours under a scalpel.
Dr. Benjamin Chung, associate professor of urology at Stanford University, said: “We found that although there is no statistical difference in the effect of surgical treatment and length of stay, there is a higher cost of surgical intervention for robots and longer operation time. The possibility is also higher."
At present, there are about 60 "Da Vinci robots" in the British hospital system, which provide robot-assisted surgical services. Each "Da Vinci Robot" costs about 1 million pounds (about 87.14 million yuan). These surgical robots provide 3D enhanced surgical images and special medical instruments such as miniature cameras and micro tools.
The researchers at Stanford University also stated that robots are undoubtedly helpful in fine surgery that requires a higher level of detail or an expandable in-vivo suturing operation.
But this new study shows that for surgical procedures that are not technically difficult, such as removing the entire kidney, human doctors are likely to perform better.
Although, these researchers also stated that as time goes by, the time required for robots to perform surgery will be shorter, and the cost gap between human doctors and “machine doctors†performing surgery will also be reduced, but in the current situation, the results of the study It shows that robot-assisted surgery is not always the best choice for patients.
"Everyone will certainly have such an impulse. I will use the most expensive medical equipment," added Dr. Chung.
"But it's also important to maintain rational consumption. We should know how to spend money in the end."
"Although there are some advantages for robots to perform surgical operations, these advantages can really convince us that these extra money are really worth the money?"
