Abstract

Sonda láser multipunto eléctricamente conmutable (10) para su utilización en cirugía oftálmica para fotocoagular un tejido, que comprende: un alojamiento cilíndrico (30) que tiene una región interior; una o más lentes (40, 44) dispuestas dentro de la región interior, estando cada lente configurada para transmitir un haz láser; y un sistema de exploración (42) dispuesto dentro de la región interior, comprendiendo el sistema de exploración una primera célula de exploración (110a) y una segunda célula de exploración (110b), estando la primera célula de exploración dispuesta para mover el haz láser a lo largo de un primer eje de coordenadas y estando la segunda célula de exploración dispuesta para mover el haz láser a lo largo de un segundo eje de coordenadas ortogonal al primer eje de coordenadas para permitir un guiado de haz bidimensional, comprendiendo cada célula de exploración un material electroóptico (80), pudiendo el sistema de exploración ser controlado por un controlador (112) de la sonda láser para realizar lo siguiente durante una serie de iteraciones para producir un patrón de puntos de láser bidimensional que coincide con un patrón bidimensional de los extremos de entrada de una pluralidad de fibras ópticas de salida (56) de la sonda láser: recibir voltajes del controlador (112) de la sonda láser; y guiar eléctricamente el haz láser con el material electroóptico de las células de exploración desde una dirección actual hasta un dirección siguiente en respuesta a las voltajes, comprendiendo cada célula de exploración: una primera capa de electrodos (144) y una segunda capa de electrodos (150) opuesta a la primera capa de electrodos; un elemento electroóptico (146) que comprende el material electroóptico (80) y dispuesto entre la primera capa de electrodos y la segunda capa de electrodos; y comprendiendo la segunda capa de electrodos una serie de electrodos de tipo tira (152) que incluye un primer electrodo de tipo tira en un primer lado de la célula de exploración y un segundo electrodo de tipo tira en un segundo lado de la célula de exploración opuesto al primer lado en vista en planta de la célula de exploración; en el que, para una dirección de guiado de haz dada, el controlador está dispuesto para aplicar un voltaje diferente a cada uno de entre los electrodos de tipo tira, cambiando monotónicamente dicho voltaje con la posición de los electrodos de tipo tira desde el primer lado hasta el segundo lado de la respectiva célula de exploración.
