Abstract

La présente invention porte sur un instrument manuel chirurgical que l'on utilise dans la chirurgie plastique sur le visage ou pour le retrait d'une tumeur osseuse et de protubérances. L'instrument manuel comprend un mécanisme (un arbre de transmission (19), une articulation sphérique inclinée (13), un vilebrequin (12) et un bras de manivelle (11)) permettant de convertir la rotation d'un moteur en un mouvement alternatif linéaire au sein du corps de l'instrument manuel, un adaptateur pour connexion accessoire (10) connecté au mécanisme en vue de la transmission du mouvement alternatif linéaire du mécanisme dans une racle ou une scie chirurgicale, un passage de décharge d'un fragment osseux (4) dans l'adaptateur connecté à un accouplement d'aspiration (1), un passage de solution saline (3) comprenant l'accouplement (1) et un tube de raccord d'administration de la solution saline permettant d'éviter la génération de chaleur provenant d'une partie de coupe pendant l'opération de taille de l'os, une valve (5) permettant de régler l'administration de la solution saline. On peut ainsi effectuer une taille de l'os en continu sans à peine nécessiter d'incision.
