Abstract

L'invention concerne un manche amélioré destiné à un instrument microchirurgical, de même que des instruments microchirurgicaux mettant en oeuvre un tel manche. Ce manche comporte un élément de saisie permettant de saisir l'instrument entre l'index et le majeur de la main, et il comporte également un élément de commande, couplé de manière pivotante sur l'instrument et conçu pour entrer en prise de manière opérante avec un outil microchirurgical. Cet élément de commande possède une géométrie destinée à épouser le pouce de la main. Ce manche permet à une personne d'actionner l'outil microchirurgical par déplacement de l'élément de commande à l'aide du pouce.
