Abstract[English]
The current invention is about the "dura dissecting knives," which are used to sharply cut and expose both the cranial and the spinal dura safely with a built-in sharp knife while introducing a built-in metallic dissector protective barrier between the dura and the underlying neural tissues in the brain and the spinal cord for extended protection and simultaneous pre-hand dissection, easily manipulated in tricky surgical corners and deep spinal fields simply and seamlessly, time-effectively, and without the need of any other assisting instruments. The invented operative instruments consisted of the footplate (element number 1 in figure l)the shaft of the instrument (element number 2 in figure 1) the sharp knife built-in between the shaft and the upper surface of the footplate, (element number 3 in figure 1) with the underside of the footplate being wholly smooth and protecting the underlying neural tissues during dissection while the instrument is advanced simply forward through a small dura snip and the advantageous footplate-to-shaft angle (element number 4 in figure 1).[French]
La présente invention concerne des "lames de dissection de dure-mère", qui sont utilisées pour couper de manière nette et mettre à nu à la fois la dure-mère crânienne et la dure-mère spinale en toute sécurité avec une lame tranchante intégrée tout en introduisant une barrière de protection de dissecteur métallique intégrée entre la dure-mère et les tissus neuronaux sous-jacents dans le cerveau et la moelle épinière pour une protection étendue et une dissection pré-manuelle simultanée, facilement manipulées dans des coins chirurgicaux étriqués et des secteurs spinaux profonds simplement et sans interruption, de manière efficace dans le temps et sans nécessiter d'autres instruments d'assistance. Les instruments d'opération selon l'invention sont composés de la plaque de base (numéro d'élément 1 sur la figure 1), de la tige de l'instrument (numéro d'élément 2 sur la figure 1), de la lame tranchante intégrée entre la tige et la surface supérieure de la plaque de base, (numéro d'élément 3 sur la figure 1), la face inférieure de la plaque de base étant entièrement lisse et protégeant les tissus neuronaux sous-jacents pendant la dissection tandis que l'instrument est avancé simplement vers l'avant à travers une petite fente de dure-mère et l'angle avantageux plaque de base-tige (numéro d'élément 4 sur la figure 1).
