An obturator for penetrating tissue includes an outer member defining a longitudinal axis, and having proximal and distal ends, a leading member disposed adjacent the distal end of the outer member and having a tissue contacting outer surface, and a blade mounted adjacent to the leading member. The blade is adapted for at least traversing movement relative to the longitudinal axis to thereby traverse the outer surface of the leading member to facilitate penetrating of tissue during advancement of the leading member within the tissue. The leading member may include an optical window adapted to permit passage of light therethrough for detection by a clinician.
L'invention concerne un obturateur destiné à pénétrer dans un tissu, comprenant: un élément externe formant un axe longitudinal, possédant une extrémité proximale et une extrémité distale; un élément avant jouxtant l'extrémité distale de l'élément externe et possédant une surface externe destinée à entrer en contact avec le tissu; et une lame montée à proximité de l'élément avant. La lame est conçue pour effectuer au moins un mouvement transversal par rapport à l'axe longitudinal, afin de traverser la surface externe de l'élément avant, pour faciliter la pénétration du tissu durant le mouvement vers l'avant de l'élément avant dans le tissu. L'élément avant peut comprendre une fenêtre optique conçue pour permettre le passage de la lumière pour que le clinicien puisse observer la lame.
