An optical 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 an optical window adapted to permit passage of light therethrough for detection by a clinician, and a penetrating member mounted adjacent the leading member and having a penetrating surface adapted to facilitate penetrating of tissue. The leading member is adapted for longitudinal movement between a first longitudinal position and a second longitudinal position. The penetrating surface of the penetrating member is at least partially exposed upon movement of the leading member from the first longitudinal position to the second longitudinal position.
L'invention concerne un obturateur optique pour pénétrer dans un tissu comprenant un élément externe définissant un axe longitudinal et ayant des extrémités proximale et distale, un élément avant disposé au voisinage de l'extrémité distale de l'élément externe et ayant une fenêtre optique apte à permettre le passage de lumière à travers elle pour une détection par un clinicien, et un élément pénétrant monté au voisinage de l'élément avant et ayant une surface de pénétration apte à faciliter la pénétration dans le tissu. L'élément avant est adapté pour un mouvement longitudinal entre une première position longitudinale et une seconde position longitudinale. La surface de pénétration de l'élément pénétrant est au moins partiellement exposée lors du mouvement de l'élément avant de la première position longitudinale à la seconde position longitudinale.
