Argon-Helium Targeted Cryosurgery System (Ar-He knife for short) is a multi-probe, high precision, rapid freezing and rapid re-warming surgical system. It is a physical therapy that can completely destroy the tumor, has precise treatment effect, does not lead to the spread of cancer cells, is minimally invasive and painless, has fast recovery, does not damage normal tissues, and has no toxic side effects unlike radiotherapy. Treatment Principle Argon gas rapid ultra-low temperature cooling technology can be used to freeze the diseased tissue to -120~165℃ within 10 seconds by releasing argon gas rapidly at the tip of the knife; and to thaw the ice ball and warm it up rapidly by releasing helium gas rapidly at the tip of the knife, which can completely destroy the tumor with one cold and one heat. The speed, time and temperature of cooling and warming, and the size and shape of the ice ball can be precisely set and controlled. (In vitro experiment: the ice ball formed after rapid cooling) The cancer cells destroyed by freezing can also induce specific antibodies, similar to the tumor vaccine planted in the body, which can enhance the immune response of the body and destroy the residual cancer cells. Indications Ar-He knife indications Treatment advantages Compared with traditional freezing methods, Ar-He knife has the following advantages: the system is easy to operate and interventional puncture operation; slight damage to tissues in the puncture path, complete destruction of target tissues, and strong target selectivity; intraoperative and percutaneous targeting of tumors can be performed; less damage to patients, less bleeding, fewer complications, and faster recovery; single and repeated treatment is possible; it can be used alone or It can be used alone or combined with chemotherapy, radiotherapy or surgical therapy. 1.No incision, little trauma, no obvious pain, fast recovery after surgery; 2.Tumor cells die, pressure is reduced, tumor shrinks after 1 to 3 months, clinical symptoms improve; 3.Reactivation of the body’s immune system, conducive to the improvement of survival quality; 4.Efficacy similar to surgical resection, can be repeatedly frozen, can be combined with radiotherapy, chemotherapy, etc.; 5.Adapted to patients with all stages of lung cancer: early stage lung cancer can achieve radical The effect is similar to surgical resection and can be repeatedly frozen.
