Abstract
Un dispositivo electroquirúrgico (100) para cortar y sellar tejido, comprendiendo el dispositivo electroquirúrgico (100) comprendiendo: una mordaza superior (120), situada en un extremo distal del dispositivo electroquirúrgico (100) y opuesta a una mordaza inferior (132), la mordaza superior (120) conectada de manera pivotante a la mordaza inferior (132) mediante una conexión (140) de pivote, y un mecanismo de muñeca entre un eje alargado (102) del dispositivo electroquirúrgico (100) y las mordazas superior e inferior (120, 132), en el que las mordazas superior e inferior (120, 132) se pueden desplazar en el mecanismo de muñeca para permitir que las mordazas superior e inferior (120, 132) se doblen con relación al eje alargado (102), en el que el mecanismo de muñeca comprende una sección (170) de muñeca que tiene una interfaz de pivote no circular (171); y la sección (170) de muñeca comprende una vértebra (173) y un casquillo (182), en la que la interfaz de pivote no circular (171) está entre la vértebra (173) y el casquillo (182), caracterizado por que la sección (170) de muñeca comprende un acoplamiento de enderezamiento automático entre la vértebra (173) y el casquillo (182) para empujar las mordazas superior e inferior (120, 132) hacia una posición centrada.

necesidad de largas longitudes de los componentes y de geometrías con tolerancia estrecha detrás de las mordazas para controlar la alineación. Las superficies 131 y 133 de acoplamiento en forma de V también tienen unas áreas superficiales más grandes que las superficies planas, resultando un área incrementalmente más amplia para enganchar el tejido.
La línea central axial 123 de la superficie 131 de acoplamiento se encuentra con la línea central axial 135 de la superficie 133 de acoplamiento a lo largo de una línea 137 que está desplazada de una línea central 101 del dispositivo 100. En esta disposición, puede alejarse el plano 103 de corte de la línea central 101 del dispositivo 100, permitiendo que la cuchilla 160 de corte sea situada lejos del centro de modo que puedan colocarse otros componentes hacia el centro del dispositivo.
Resorte de mordaza inferior
Con referencia de nuevo a la Figura 1, la carcasa 130 de mordaza inferior contiene un resorte 134 de mordaza inferior entre la carcasa de mordaza inferior y la mordaza inferior 132. El resorte 134 de mordaza inferior se apoya contra el interior de la carcasa 130 de mordaza inferior para pivotar la mordaza inferior 132. En esta configuración, el resorte 134 de mordaza inferior desvía una porción distal 137 de la mordaza inferior 132 hacia la mordaza superior
120.
Los dispositivos electroquirúrgicos conocidos que incluyen resortes de mordaza inferior sitúan el resorte en una sección proximal de la mordaza inferior, en un punto situado proximalmente con respecto al punto de pivote. Para proporcionar espacio para el resorte, se elimina cierta cantidad de material de la porción proximal de la mordaza inferior, y/o de la carcasa de mordaza inferior en un área similar. Esta eliminación de material puede crear una disminución sustancial de la resistencia y la rigidez en la sección proximal de la mordaza inferior y/o de la carcasa de mordaza inferior. La resistencia y la rigidez de la mordaza son especialmente importantes en la sección proximal de la mordaza inferior y de la carcasa de mordaza debido a que la sección proximal es un área crítica para proporcionar una fuerza de compresión. La Figura 1 muestra el espesor relativo de la mordaza inferior 132 en su sección proximal 135 y en su sección distal 137.
Para evitar la pérdida de resistencia y rigidez de la mordaza en la porción proximal 135 de la mordaza inferior 132, se sitúa el resorte 134 de mordaza inferior en la porción distal 137 de la mordaza inferior. Esto conserva más masa alrededor de la sección proximal 135, donde se necesita. La sección distal 137 de la mordaza inferior 132 tiene más masa para empezar que la sección proximal 135 y, por lo tanto, es más adecuada para alojar el resorte 134 de mordaza inferior.
El resorte 134 de mordaza inferior se engancha por fricción con la mordaza inferior 132 en dos ubicaciones, 132a y 132b. Este enganche en dos ubicaciones ayuda a transferir energía desde la carcasa 130 de mordaza inferior hasta la mordaza inferior 132.
Mecanismo de articulación
Las Figuras 9-12 muestran un mecanismo 200 de articulación según la invención. El mecanismo 200 de articulación controla el movimiento de flexión o de giro en la sección 170 de muñeca, lo que permite que la mordaza superior 120 y la mordaza inferior 132 se doblen hacia la izquierda o hacia la derecha. Más específicamente, el mecanismo 200 de articulación puede operarse para aplicar una fuerza de tensión a una de las secciones 172 y 174 de cable de articulación, para doblar el dispositivo en la sección 170 de muñeca.
El mecanismo de articulación 200 incluye un par de discos de indexación 210, que retienen la posición articulada de las mordazas superior e inferior 120 y 132. El mecanismo 200 de articulación incluye también un articulador 220, que puede operarse para girar los discos de indexación 210. El articulador 220 tiene un par de agarraderos 222 que se extienden hacia fuera desde los discos de indexación. Los agarraderos 222 y los discos de indexación 210 pueden desplazarse de forma giratoria en una carcasa 230. La carcasa 230 tiene una pared interior 232 recubierta con unas muescas 234 de trinquete. Cada disco de indexación 210 tiene un par de brazos 212 de indexación que pueden operarse para enganchar y desenganchar las muescas 234 de trinquete, cuando se gira el disco de indexación en la carcasa 230. Las muescas 234 de trinquete están separadas entre sí por una serie de dientes 235 de trinquete que apuntan hacia dentro. Cada brazo 212 de indexación tiene un extremo distal 213 con una punta 215 puntiaguda, configurado para interactuar y enganchar de forma deslizante con las muescas 234 de trinquete y los dientes 235 de trinquete a medida que los discos 210 de indexación giran en la carcasa. Los brazos 212 de indexación están formados por un material flexible resiliente que permite que los brazos de indexación se flexionen o doblen radialmente hacia dentro, hacia el centro de los discos 210 de indexación, en respuesta al contacto entre la punta 215 y los dientes 235 de indexación. Cuando las puntas 215 enganchan con las secciones más interiores de los dientes 235 de trinquete, los brazos 212 de indexación se doblan hacia dentro debido a la energía almacenada. A medida que los discos 210 de indexación giran y las puntas 215 se alinean con las muescas 234 de trinquete, los brazos 212 de indexación enganchan por presión hacia fuera y vuelven a un estado relajado, con las puntas colocadas en las muescas de trinquete.
El mecanismo 200 de articulación incluye un mecanismo de centrado 240, que desvía el articulador 220 a una condición centrada o “neutral”. En la Figura 9 se muestra la condición neutral. El mecanismo de centrado 240 incluye
