When lung cancer is detected early, the treatment is effective and the disease is controlled. If treatment is delayed, the disease will be aggravated quickly and even lead to uncontrollable and later fatal. At present, the best treatment method for lung cancer in early stage usually adopts American Ar-He knife cryoablation for lung cancer treatment. So what is Ar-He knife? Ar-He knife is a minimally invasive ultra-low temperature cryoablation surgery system that combines aerospace, bio-sensing, electronic computer, conformal monitoring, targeted therapy and other technologies, representing the highest level of cryo-engineering at present. After hundreds of years of continuous improvement and upgrading of cryotherapy, it can be regarded as a breakthrough in tumor ablation therapy technology, which is not only used for cryotherapy of previous surface tumors, but more prominently for deep tumors in vivo that can be monitored and treated. The Ar-He knife adopts local anesthesia and punctures under the guidance of CT, B-ultrasound and MRI. The 1.4-3 mm thick Ar-He knife is accurately punctured into the tumor, and an ice ball with a diameter of 3-4.5-6 cm and a temperature of -160 degrees Celsius is formed around the tip of the needle. The combination of multiple needles and the adjustment of argon output power can form various shapes of ice balls to completely destroy the tumor tissue and avoid damaging too much normal tissue. Advantages of argon helium knife for lung cancer treatment: 1. Significant effect: control the three confirmed effects (confirmed temperature, confirmed time, confirmed range), for tumors with large lesions, argon helium cryosurgery can combine multiple needles to kill cancer cells, for smaller tumors, lesions, single needle ablation of cancer cells can achieve 100% elimination – with good At the same time, it can produce anti-tumor antibodies and increase the immunity of the body, which can completely eliminate tumor cells and prevent tumor recurrence. 2.Minimal trauma: less damage to patients, no chest opening, no or less bleeding, percutaneous or transcatheter treatment, less pain to patients. 3.Short operation time: short treatment time, small trauma, fast recovery of patients, relatively low requirements for patients, generally patients can tolerate. 4.Easy to operate: high success rate, few complications; patients recover quickly and can be discharged in a few days after surgery. 5.Efficacy: significant effect, reasonable price, easy for patients to accept. 6, slight damage: no toxicity to normal organ tissue cells, minor surgical damage, can be repeatedly done. 7.Single effect joint times: can be performed alone, can be combined with radiation, chemotherapy or surgical therapy to increase the efficacy. 8.Unique efficacy: especially for cases where surgery or other treatments fail, there is indeed unique efficacy. 9, low cost: the cost of surgery is about 20,000 yuan, generally a treatment can be completed, observation 5-7 days can be discharged, so the non-therapeutic expenses are less; easy for patients to accept.
