Abstract

Se utiliza energía electro-quirurgica en combinacion con un util quirurgico para cerrar los vasos y el tejido vascular de un paciente; uno de los avances importantes del presente sistema consiste en que puede cerrar de manera eficaz los vasos de un paciente sin dejar ningun material extraño en el cuerpo del paciente; el presente sistema está capacitado también para cerrar vasos tan grandes como de diez milímetros de diámetro; otra ventaja del presente sistema consiste en que el cirujano puede inspeccionar visualmente la integridad del cierre; la invencion trabaja con una combinacion de presion y aplicacion controlada de energía electroquirurgica para conseguir el resultado deseado, se utiliza un util quirurgico para coger y aplicar una cantidad apropiada de fuerza de cierre al tejido del paciente; el util está capacitado para conducir energía electro-quirurgica hasta el tejido de manera coincidente con la aplicacion de la fuerza de cierre; un método para cerrar los vasos y el tejido vascular de un paciente incluye las etapas de aplicar presion a los vasos y a los otros tejidos del paciente; aplicar un primer nivel de energía electro-quirurgica a los vasos y al otro tejido suficiente para fundir las proteínas del tejido; aplicar un segundo nivel de energía electro-quirurgica a los vasos y al otro tejido suficiente para provocar la desecacion sin chamuscado; reducir la energía electro-quirurgica sustancialmente a cero durante un periodo de tiempo suficiente para permitir que los vasos y los otros tejidos se enfríen con una nueva forma comprimida, y eliminar la presion del tejido.
