French simulated space surgery 8 minutes to remove cysts. A medical team from France flew into the air with the patient on January 27, and did the first zero-gravity operation in the absence of gravity generated during the climb and dive of the aircraft, from the patient's A cyst was removed from the arm.
According to the Associated Press, the medical team of five doctors created a history in which they tied the yellow tumor with a rope and then removed it, and the mass "drifted away" from the patient. The doctor has been preparing for this surgery for three years. It is also part of the three phases of exploring zero-gravity surgery, paving the way for surgery in space by doctors or remote-controlled robots one day. Of course, this is also an experiment in itself, accumulating experience for emergency medical operations on the International Space Station in the future.
The operation was continued for three hours, but the operation itself took only 8 minutes. According to the doctor, it takes almost a long time to do such an operation in the hospital. Three doctors, two assistants and a videographer used climbing equipment to fix themselves on the aircraft bulkhead. The aircraft raised and swooped in a parabolic manner like a roller coaster to create a gravity-free condition. Dr. Dominica Martin, the head of the medical team, said: "We just did a simple technical procedure, but everything we saw showed that there is no insurmountable problem in performing surgery under space conditions. He told reporters that the surgery was as perfect as they expected.
The patient who underwent the operation was Philip Sanchez. The reason why he chose him was because he was a person who liked bungee very much and had a very strong endurance to the sudden change of gravity. During the operation, the doctor performed a local anesthesia on Sanchez, and he remained awake throughout the operation. Sanchez, 46, said: "I am a little tired, but only because my head is turning around."
Surgery is relatively simple and short-lived, but it allows the doctor to have a preliminary understanding of surgery in space, providing information on blood flow under zero gravity conditions and the need for special equipment. Doctors, part of the reason for this test, are also refuting some of the opponents who claim that surgery in space, if not impossible, is unreliable.
During the experiment, the plane made a loop in the range of 20,000 to 27,560 feet above Bordeaux. This was a specially designed airplane. When it reached the maximum altitude, the pilot turned off the engine, allowing the aircraft to drift almost without gravity. After landing for almost a period of time, the pilot flew up at a 45 degree angle. Sanchez, still wearing a bandage on his arm, recalled: "Sometimes we are joking with each other, 'Be careful, don't get caught up.' The whole atmosphere is very relaxed."
However, the medical team had to do it faster because the zero-gravity situation was intermittent, they had to wait for zero-gravity conditions to appear, and they had to fight against the nausea during the interval. Martin said: "I don't want to go to such a fairy-tale flight. It's a special feeling, but I don't think it's very interesting. In the last parabolic flight, I spit it out." People who have been riding a roller coaster in the park have experience. After the roller coaster climbs to the highest point, it suddenly falls freely, so that the things in the stomach have a feeling of turning over the river. Seen through the TV screen, the doctor performed the operation under an almost normal condition, except that there was a small pink object floating on their hands. A doctor gently bounces it aside and then drifts up a small piece of tissue.
The doctor is soberly aware that this minor operation is nothing compared to the complex surgery that the International Space Station may need. It is not worth too much, but it is an important first step. Martin said that no one knows what kind of surgery is best for implementation without gravity. Martin said: "If I have two hours of gravity-free conditions, I can remove an appendix or something else, but we only have 10 minutes to perform surgery under such conditions. Our surgery shows that everything we do All are adequate, and the operating room we designed is also suitable. The patient was found to have no problems through surveillance."
The "operating table" on the plane can be reused and easily placed in the plane. The operating table is 13 feet long and 6.5 feet high and wide. This operating table can be used not only on Earth. Of course, it can also be used in theaters or in carrying out humanitarian missions. The procedure was part of a three-stage analysis of the medical procedure under near-gravity conditions. In the first phase, Martin and his team members performed microsurgery on the tail of a mouse in a similar flight in 2003. The operation was much more complicated than the surgery on Wednesday. This operation was the second. stage. He said that they can't take any risks. Martin refused to discuss the third stage, but it was revealed that the third stage was a gravity-free operation in the air by a robot remotely controlled by the ground. If funding permits, the third phase will be carried out next year.
The operation was supported by the French National Space Research Center and the European Space Agency. NASA has performed robotic surgery on animals in submarine laboratories near Florida, and the conditions are similar to those on the track. Lauren Konik, chief anesthesiologist of the French medical team, said: "There are more than 400 people in space, and they may be injured unconsciously."
