Interstitial microwave antenna with side effect to hipertemia in tissues in minimal invasive surgery

摘要

"Antenna microwave hyperthermia in interstitial indeed lateral fabrics in minimal invasive surgery.The application device (1), for example.A needle of a catheter that has metal or plastic in the terminal portion (2) of the free end of a gradual increase of the thickness to form substantially a rail guide (3) which ends in an ab(4) made in the lateral centrally manage client configurations and launch the application device (1).Thus, an interstitial antenna (10) is obtained formed by a coaxial tube having an outer conductor (7),A dielectric layer (9), and a central conductor (8) embedded in the dielectric layer (9) that isolates the outer conductor (7).The antenna (10) can be placed in a target tissue along a direction of actuation at an angle 244 with the direction of introduction.In this way, the antenna (10) reaches a surface isothermal real, i.e.A mass of tissue is coagulated in a curved surface (13).Since the tip of the application device (1) is connected electrically to the outer conductor (7) and increases its area of action.
