Abstract

Se da a conocer un dispositivo de regulacion para regular variablemente la longitud de una aguja espinal y aguja epidural combinadas y el método para llevar a la práctica el mismo. En una variante, el dispositivo de regulacion presenta un par de miembros de deslizamiento colocados casi concéntricamente a los cuales puede ajustarse separadamente unaa un elemento de resorte para acoplar selectivamente la aguja espinal. El elemento de resorte incluye un extremo fijado al miembro de deslizamiento que asegura la aguja epidural, un extremo libre manipulable por un usuario a por lo menos un pasaje o abertura que se coloca entre los extremos fijo y libre a través de los cuales pasa la aguja espinal. La abertura se configura para permitir ya sea el deslizamiento libre o la sujecion de la aguja espinal dependiendo del accionamiento del elemento de resorte del médico. Mediante el accionamiento del elemento de resorte, el médico puede controlar el movimiento axial entre los miembros de deslizamiento regulando de esta manera la extension de la aguja espinal con relacion a la aguja epidural. Los miembros de deslizamiento pueden configurarse en una variedad de configuraciones o dimensiones para acomodar las distintas combinaciones de las agujas espinal y epidural. El dispositivo se puede proporcionar preensamblado ya sea con una o ambas agujas espinal o epidural, o puede emplearse con una aguja espinal, una aguja epidural o ambas de procedencia separadas.
