DEVELOPMENT OF A COMPLEX OF DEVICES FOR MICROWAVE ABLATION OF TUMORS
Problem: The lack of minimally/minimally invasive methods for solving surgical problems. The absence of Russian-made microwave ablation devices. Solution: The device for microwave ablation of tumors - "Lance MWA" contains an emitter connected to a microwave generator, made in the form of a piece of coaxial line, including external and internal conductors isolated from each other, with the internal conductor protruding outward relative to the external one. The emitter is installed with a gap in a radio-transparent catheter, and its working part is covered with a dielectric layer with a thickness equal to the thickness of the outer conductor of the coaxial line. Microwave ablation is a minimally invasive method of treating malignant and benign tumors. The procedure is most often used for liver cancer, but can be used for tumors of bones, lungs, kidneys, pancreas and other organs. An antenna is inserted into the tumor, which emits electromagnetic energy. It is transmitted from the generator via a coaxial waveguide and delivered directly to the tissues, ensuring the locality of their heating. 2. The radiated energy causes the water molecules to heat up. Water molecules transfer energy to the surrounding tissue and when a sufficiently high temperature is reached, its destruction occurs. 4. It is important to note that microwave energy directionally affects the area that contains tumor tissue, so healthy tissues and vital structures outside a given area are not subjected to excessive thermal damage.
