1. Wide indications: argon helium knife can ablate almost all solid malignant tumors

2. Accurate and reliable treatment effect: argon helium knife treatment can be guided by various imaging equipment, with convenient and accurate positioning, real-time display of the treatment process and timely and reliable effect evaluation.

3. Complete green therapy: physically crush and destroy cancer cells without coking and coagulation reaction, and the surface antigen of damaged cancerous cells can stimulate human immune response.

4. Significant analgesic effect: rapid freezing can block neural pathway and destroy pain conduction, which has significant analgesic and hemostatic effects.

5. The advantages of minimally invasive treatment are obvious: it is local anesthesia and percutaneous puncture treatment without surgery. The minimum diameter of the knife is only 1.7mm. The trauma of percutaneous puncture to patients is very small and there is little bleeding, which realizes the real minimally invasive treatment. It greatly shortens the treatment time of patients and reduces pain.

6. Low treatment cost and reduce the economic burden of patients: for patients with advanced tumors, such as liver and lung metastasis after rectal cancer surgery, the cost of argon helium knife treatment of metastatic tumors is only half of that of surgical resection, and argon helium knife in the United States has been included in the scope of medical insurance in many cities.
