Description

Ablation isolation protection device for minimally invasive intervention of liver cancer

Technical Field

Background

The current ablation treatment technology is to follow the principles of accurate medical treatment and minimally invasive medical treatment in the current minimally invasive intervention, and to utilize the medical imaging technology to accurately puncture and guide treatment electrodes such as radio frequency, microwave, freezing and the like into a tumor target area under the guidance of images such as computed tomography, nuclear magnetic resonance, digital vascular subtraction and ultrasound, so as to implement accurate minimally invasive physical ablation and in-situ tumor inactivation. For example, during the radio frequency ablation treatment, the radio frequency electrode needle inserted into the tumor tissue emits radio frequency waves to make polar molecules of the tumor tissue vibrate at high speed, adjacent molecules rub against each other and collide with each other to generate heat, and the temperature of the treatment area can reach 90-100 degrees, even exceed 100 degrees. The microwave ablation treatment is to puncture the tumor central area through the skin by using a microwave antenna needle, and a micro microwave oven with the size of 1 millimeter is arranged at a certain point of the microwave needle, so that the microwave magnetic field released by the microwave antenna needle can make surrounding molecules rotate at a high speed and raise the temperature through friction, thereby solidifying, dehydrating and necrosis of surrounding tumor tissues, and achieving the treatment purpose. Cryoablation is performed by rapidly reducing the temperature of the cryoprobe tip to-175 ℃. Ice crystals are rapidly formed in and out of the cells after cooling, resulting in dehydration and rupture of tumor cells. Simultaneously, freezing causes the micro blood vessels to shrink, the blood flow is slowed down, the micro thrombus is formed, the blood flow is blocked, and the ischemic necrosis of tumor tissues is caused.
