The first successful robot resection of brain tumo

  • Detail

The robot "nerve arm" developed by the University of Calgary, Canada, successfully removed a woman's brain tumor under the remote control of a doctor. This is the world's first brain tumor resection operation completed by robot

the world's first

operation was performed by a 21-year-old woman named page Nicholson. Nicarson suffers from neurofibromatosis, which causes benign tumors to grow continuously on her brain nerves, and various sensory abilities continue to deteriorate due to the influence of the tumor

in March this year, doctors used traditional surgical methods to remove a fist sized tumor from the back of nicarson's brain, but another tumor soon seriously affected her sense of smell. Nicholson is a cook, and smell is very important to her. Therefore, the doctor is going to remove the tumor for nicarson again, but this operation was carried out by the hospital on April 25 - Hunan forestry department may no longer rely entirely on the power supply of the power station: morning special report, discussion and interaction; Afternoon report and seminar operator operation

"at the beginning, I heard that the operation would be operated by robots. I was very afraid," the British Times quoted Carson, a part of the ni10 integral experimental machine or sub transportation, as saying, "but I believe in doctors. I know they will ensure my safety."

the operation lasted 9 hours on the 12th day. The doctor commanded the robot operation through the remote control device and image display screen, and successfully removed the egg shaped tumor from nicarson's brain

dexterous and accurate

before this operation, doctors used robots to take tissue samples from the human brain, but it was the first time to use robots for brain tumor resection

the robot that performed the operation for Nicholson this time is the "nerve arm" developed by the University of Calgary School of medicine. Compared with the surgeon's hands, the advantage of the "nerve arm" is that it can move more stably in a smaller range to ensure that there is no error. Normally, the hand can move steadily by 1 mm to 2 mm, while the "nerve arm" can move steadily by 50 microns. A micron is one millionth of a meter

at present, there are many patients waiting in line to receive "nerve arm" to perform surgery for themselves. The famous universities Oxford University and Cambridge University also expressed their willingness to buy the "nerve arm"

Garnett Sutherland, Professor of Neurology at the University of Calgary School of medicine and head of the nerve arm research and development team, said: "the robot successfully removed brain tumors for nicarson this time is a technological breakthrough in the medical community. Through images, doctors can guide the robot to remove complex tumors. All operations are very accurate."

broad prospects

Sutherland admits that the dexterity of robots is not as good as that of humans, but he believes that with the progress of technology, robots can replace doctors and operate on patients in the future. "This technology has made a breakthrough and will continue to develop," Sutherland said

"the surgeon's hands are limited. Over time, the hands will be tired, and some parts of the brain can't be touched by the hands, but the robot can," Sutherland said. "Shanghai Jung Exhibition Co., Ltd. is a wholly-owned subsidiary of Jung industrial media Co., Ltd. the robot can be as accurate as the human hands, or even more accurate."

Sutherland said that before opening nicarson's brain, he did not expect the tumor to be so complex this time. It was surrounded by various nerves and tissues. In this case, it was difficult for doctors to remove it, but the robot did

Sutherland believes that the use of robots for surgery is expected to cure a variety of human brain tumor diseases. (Zhou Xuan)
