For the tumor patients encountered in clinical work, most of them are already in the middle or late stage when the tumor is discovered, losing the chance of surgical resection. Therefore, the majority of patients need to use minimally invasive interventional tumor treatment in the process of fighting with tumors. Minimally invasive interventional therapy is a minimally invasive medical method to diagnose or treat diseases under the guidance of medical imaging equipment (X-ray, CT, ultrasound, etc.), using puncture needles, catheters, guidewires, stents and other interventional devices, integrating advanced medical imaging technology, drug therapy, biological and genetic technology and high technology (such as freezing, microwave, radiofrequency ablation, chemical ablation, etc.). The surgeon punctures the human skin to form tiny orifices or feeds interventional devices through physiological cavities to perform various minimally invasive interventional operations and surgeries, which are characterized by small trauma, fast postoperative recovery, certain efficacy and few complications, and are also known as “surgery through a needle hole”. For some diseases that are highly traumatic, risky and difficult to treat by conventional surgery, interventional treatment can often be solved simply and effectively. For patients with tumors that cannot be removed surgically, most of them need to receive comprehensive treatment including minimally invasive interventional therapy.
