The controversial "head transplant" surgery has the latest news: According to the British "Daily Mail" compiled by the news, on November 17, the Italian neuroscientist Sergio Canavero was in Vienna, Austria. A press conference was held to announce that the world's first human head transplant operation has been successfully implemented on a body, and the operation site is China. Canavero said that Professor Ren Xiaoping of Harbin Medical University in China participated in the operation. On November 19th, the Science and Technology Daily reporter rushed to Harbin Medical University and asked Professor Ren Xiaoping to face the test.
“We did original, initiating researchâ€
"The operation was done at Harbin Medical University." Ren Xiaoping said to the reporter, "After about 18 hours of surgery, my team and I successfully connected the head of one body to the spine, blood vessels and nerves of another body. In the following week, the data, process, and results related to this head transplant will be published in the American academic journal SNI (surgicalneurologyinternational), and all the detailed procedures for surgery will be published."
How to prove that this operation is successful?
Ren Xiaoping said: "Since academic journals publish papers, it proves that the surgery has academic value. No one has ever proposed how to do it, but we have proposed it, including how to cut, how to deal with nerves, how to deal with blood vessels and muscles, What to do, why to do this, etc. This is our result."
"This operation is too important. We did original and initial research. Some people think that this will be a milestone in the medical field. For example, central nervous system regeneration has always been considered an unbreakable obstacle. "I have been stagnating." Ren Xiaoping emphasized that "the history of human medical history is unprecedented. The surgery should solve a series of problems such as how to dissect, how to repair and reconstruct each tissue, and how to ensure maximum recovery of postoperative function. Our surgery on these aspects. Made a detailed description and innovative design."
Does the success of the transplant of the head of the body mean that the head transplant can be performed on the living body?
Ren Xiaoping said that the success rate of the living body will be known later, and the pre-clinical design plan will continue to improve.
Another voice: "Surgical surgery" can only be considered as an anatomical study
"This so-called head transplant is performed on the body. It cannot be called surgery in a strict sense." Professor Hu Yongsheng, deputy director of the Department of Functional Neurosurgery, Xuanwu Hospital, Capital Medical University, believes that "surgery should mean living on the body." The actual operation performed on the body is an anatomical or anatomical study."
Hu Yongsheng said that the current medical technology can completely achieve the reconstruction of blood vessels, nerves, muscles and bones, but the most critical problem is how the spinal cord can be perfectly reconstructed and functionally reconstructed after the disconnection. There is no breakthrough in the world. Sexual research progress, "Now talk about living head transplants, there is actually not much practical significance."
"I think that animal experiments should be fully carried out first, and surgical techniques and nerve regeneration methods should be fully confirmed before considering human experiments. This is a truly responsible approach to patients and more in line with medical ethics." Hu Yongsheng said, "The future The skull transplant is entirely possible, but it is still too far and far."
Although cautiously optimistic about living head transplants, Hu Yongsheng also believes that this anatomical study published on the 17th can be seen as a preliminary practice of the real "head-changing experiment." "It's only a first step in its smooth implementation, and humans are far from the real port of living."
Who is "you" after the skull transplant?
At the same time as the news of "successful head transplant surgery" came, the ethical issues involved in "head-changing" also caused heated discussion again.
Hu Yongsheng pointed out that even if the skull transplant is completely feasible on the scientific and technical level in the future, how can the ethical problems that come with it be solved? Who is "you" after the skull transplant? He believes that at present, it is necessary to keep a clear head on the head transplant surgery, avoid impetuous exaggeration, scientific exploration is meaningful, and excessive propaganda is not beneficial.
In this regard, Ren Xiaoping said that the history of human medical development was developed in one dispute. The first kidney transplant in 1953, at that time, academics and society criticized that it should not be done, people should die normally, others can not change. This journey. The first case of heart transplantation was also the case. There were even complaints from the public that the doctor was unreasonable, illegal, and irresponsible. The hand transplant that he participated in the United States 20 years ago was also included in the US Medical Insurance Act last year. He said that new things will be controversial and controversial will be perfect.
"As a doctor, this is my mission. The most basic element of ethics is life, survival, no life and survival cannot talk about ethics. Medical ethics is to save lives. A new thing appears, people can regulate it and discuss it, but Can't hinder it, history proves that there is no power to hinder." Ren Xiaoping said. (Technology Daily)
