Agence Rrance-Presse--- French doctors this week carried out the world’s first operation on a human in zero gravity, using a specially adapted aircraft to create conditions in space.

During a three-hour flight from Bordeaux in southwest France, the team of surgeons and anesthetists (麻醉师) successfully removed a benign tumor (良性瘤) from the forearm of a 46-year-old volunteer. The experiment was part of a program backed by the European Space Agency to develop techniques for performing robotic surgery aboard the International Space Station or at a future Moon base.

“Now we know that a human being can be operated on in space without too many difficulties,” says the team leader Dr. Dominique Martin.

Under normal ground conditions, the operation would be performed under a local anesthetic. Without gravity, the surgeon’s work is harder and the patient’s body reacts differently. Blood doesn’t pump in the same way.

The custom-designed Airbus 300 aircraft performed a series of parabolic swoops (抛物线飞行), each creating between 20 seconds of weightlessness. The process was repeated 32 times.

Fixed inside a custom-made operating block, three surgeons and two anesthetists worked during these periods, with their instruments held in place with magnets around the patient’s bed. The next part of the program is to carry out a remote-controlled operation using a robot controlled from the ground by satellite. This experiment should take place within a year, Martin says.

Anesthetist Dr. Laurent de Coninek says that zero-gravity surgery offers huge promise for space exploration, although it would at first be limited to treating simple injuries. Today more than 400 people have already traveled into space. The chances of injuries occurring during missions will become even greater and to bring a wounded person back to the earth for treatment is both risky for them and expensive.
