Abstract

Un instrumento crioquirúrgico (1), que comprende un cable (2) largo y elásticamente flexible que termina en una unidad de congelación (3) asociada con una punta de contacto (6) delantera, incorporando dicha unidad de congelación (3) un dispositivo termoeléctrico de refrigeración (13), operable selectivamente, para congelar normalmente dicha punta de contacto (6) delantera, teniendo dicho dispositivo de refrigeración una superficie distal (14), que actúa como dicha punta de contacto delantera de la unidad de congelación, y una superficie proximal (16), en la que termina el dispositivo de refrigeración, comprendiendo el instrumento, además, un tubo de entrada (19)que se extiende a lo largo de dicho cable (2) elásticamente flexible, y que termina junto a dicha superficie proximal (16) del dispositivo de refrigeración, para entregar un flujo de fluido de refrigeración de aguas arriba a dicha superficie proximal, desde un sistema de refrigeración externo, caracterizado porque dicho tubo de entrada (19) está provisto de, al menos, una unidad de refrigeración (22), que se extiende a lo largo de parte de la longitud del tubo de entrada y separada de dicha superficie proximal (16) del dispositivo de refrigeración, para enfriar bruscamente dicho flujo de fluido de refrigeración de aguas arriba antes de que llegue a dicha superficie proximal.
