Abstract

Abstract Translated from French L'invention concerne un adaptateur vissable dans le crâne d'un patient et destiné à recevoir un transducteur de pressions. Cet adaptateur est formé d'une douille 8 comportant un filetage 10 à son extrémité proximale 9, dont une partie est conique, cependant que les fils du filetage sont usinés en dépouille dans cette zone, de manière que lors du vissage de la douille 8 dans un perçage du crâne d'un patient, on obtient un effet d'autotaraudage et d'enlèvement de copeaux, cependant que des rainures longitudinales (telles que 15) sont ménagées uniquement dans la zone des premiers filets dudit filetage, pour la reception des copeaux d'os. Application notamment à la mesure de la pression intra-crânienne. The invention relates to an adapter which can be screwed into the skull of a patient and intended to receive a pressure transducer. This adapter is formed of a sleeve 8 having a thread 10 at its proximal end 9, part of which is conical, while the threads of the thread are machined undercut in this zone, so that when screwing the sleeve 8 in piercing the skull of a patient, a self-tapping and chip removal effect is obtained, while longitudinal grooves (such as 15) are formed only in the area of the first threads of said thread, for the reception of chips back. Application in particular to the measurement of intracranial pressure.
