    If there is magic freezing will be a lot of people want to have in many fantasy film and television works we often see the main character's hand, the person in front of the instant freezing want who "beautiful frozen man" refers to who in fact in the struggle with the disease frozen has been mature applications such as: tumor treatment! With a frozen knife to "freeze" the tumor "frozen to death" without a large knife can "eliminate" the tumor such a technology, who does not love it?! Zhejiang University Medical College affiliated with the first hospital radiation intervention center recently for Ningbo 67-year-old Wang Dam (admist) carried out the first tumor cryo-ablation surgery 01 cancer cells transferred to the lung doctor said: a little dangerous to say Aunt Wang, her daughter tears can not stop flowing down, "My mother is too bitter."
    " originally, 6 years ago, Aunt Wang because of long abdominal pain, black was diagnosed with rectal cancer, in the local hospital received rectal cancer treatment and removed the tumor.
    half a year after the surgery, she was told during a review: tumor cell metastasis! The liver became the first "attack" target of cancer cells, and Aunt Wang eventually underwent surgery in a Shanghai hospital to remove the right half of her liver.
    one after another, in 2016, Aunt Wang's lungs also found multiple metastasis tumors.
    ", there are many, we were all frustrated.
    " Aunt Wang's daughter said, in order to treat lung metastasis tumor, Aunt Wang has received oral targeted drugs, radio frequency ablation, particle implantation, radiotherapy and other treatment methods, these years almost every month to run to the hospital, only to basically control the condition.
    recent review found that a small tumor on Aunt Wang's left lung had significantly become larger, about 3 x 4 cm long, about the size of a ping-pong ball.
    " local hospital said the tumor location is not good, a little dangerous, suggested that we go to Zhejiang University Hospital to see.
    " in the eyes of the family, "a little dangerous" these four words weigh as heavy as a kilogram, pressure a family breathless.
    there was no delay, they found a hospital in Zhejiang University Radiological Intervention Center Peng Zhiyi director of physician.
    Images Aunt Wang's CT image shows that the tumor has been close to a ping-pong size 02 tumor close to the pulmonary artery, surgery risk doctors wondered, to "freeze to death" tumor not only large, but also close to the lung door, treatment is really difficult, and the risk is great.
    " Dr. Peng Zhiyi after receiving a detailed inquiry about the medical history, carefully and meticulously studied all of Aunt Wang's imaging data, found that the drilled tumor close to the pulmonary artery, if the radio frequency ablation, radiotherapy or routine surgery, it is easy to damage the structure around the tumor, damage the large blood vessels, causing hemorrhage, resulting in fatal consequences.
    you just let the tumor grow indiscriminately? In the face of the patients looking forward to, Dr. Peng Zhiyi proposed that the use of lung tumor cryo-ablation, also known as "helium knife frozen ablation", referred to as "helium knife", is a purely physical minimally invasible treatment.
    , "in layman's terms, it is the use of a frozen knife to 'freeze' the tumor first, so that the tumor completely inactivation, and then the tumor will slowly shrink and disappear."
    Peng Zhiyi, director of the doctor introduced, to accurately reach the tumor lesions, argon helium knife needs to be guided by CT or ultrasound operation, first inject argon into the tumor, manufacturing -130 to -150 degrees C, equivalent to the moon night temperature of ultra-low temperature, rapid freezing of tumor tissue, and then start helium, so that the temperature of the diseased tissue from ultra-low temperature to 10 to 40 degrees C, through freezing-refring-frozen-refrwining cycle of multiple tumors.
    it safe to see such a low temperature? Will it freeze other organizations? In the face of these questions from the patient's family, experts explained that the helium knife is vacuum insulation, in the refrigeration and heating process is limited to the frozen knife tip around, the damage to the surrounding fiber structure is minimal, and the frozen knife rod has a good thermal insulation, will not cause tissue damage in the puncture process, with the upgrading of equipment and technological development, safety greatly improved.
    our radiology intervention team has done a good research on its safety and effectiveness.
    "03-150 degrees C ultra-low temperature frozen tumor 2 hours surgery to successfully remove the safety of higher, smaller trauma, better treatment results, and the treatment plan has also been approved by the Zhejiang University New Technology Ethics Committee, Ms. Wang readily accepted this new method, became the first patient to receive the frozen ablation of lung tumors in Zhejiang University Hospital.
    the operation, Dr. Peng Zhiyi organized a large discussion between Zhou Xianyong, deputy director physician, Dr. Yu Shaolin attending physician and other department members, and optimized the details of the operation.
    further clear surgical program after only 3 ml of drug for partial skin immersion anesthesia, this "enemy war" began.
    only see "operational commander" Dr. Yu Shaolin wearing surgical clothing, in the "forward sentry" - CT image guidance, cleverly avoid the puncture path of important blood vessels and other "mine zones", a diameter of 1.7 mm, about a pencil core thickness of the frozen knife accurately delivered to the inside of the tumor.
    , we're ready to turn on the argon and start freezing! "Okay!" During the conversation, the frozen knife has been rapidly reduced to -150 degrees C within 50 seconds, at which point images from Sentinel CT show that the tumor tissue around the frozen knife is quickly frozen into ice balls, freezing the blood vessels that feed the tumor cells, stopping the transport of nutrients, and gradually destroying the tumor cell tissue.
    15 minutes later, the command issued another command: "Turn off the argon, turn on the helium, re-warm!" "The frozen knife re-warmed to 10 degrees C, and not long after the tumor cells thawed, the doctor re-opened the argon and froze it to -150 degrees C.
    doctor, what's the step now? "Mom, I'll be right there.
    " is going to be all right so soon, I don't feel anything.
    " surgery doctors while comforting Aunt Wang, while continuing to "cool down - re-warm" and other operations, several cycles, the tumor lesions were completely frozen, this let Aunt Wang day and night scared of the tumor was finally "removed."
    Wang was discharged the next day after a night of inpatient observation, and the two-hour operation also filled the gap in the minimally invased frozen ablation technology of tumors in Zhejiang University Hospital.
