Abstract

A laparoscopic Trocar (1) comprising a cannula (2) and an obturator (3) adapted to be housed inside the cannula (2) during crossing of the abdominal wall. The obturator (3) is provided with a tip (11) comprising, in turn, a frustoconical dilation portion (8a), a blade (10a) which protrudes from the frustoconical dilation portion and a retractable protection portion (9a), arranged around the blade (10a) and adapted to run inside the frustoconical dilation portion (8a) to move between a rest position, in which the blade (10a) is covered, and an active position, in which the blade (10a) is uncovered. The frustoconical dilation portion (8a) comprises a closed lateral wall (8b) tapering towards a free end thereof defining a circular aperture (8c) from which the blade (10a) and the protection portion (9a) protrude when in the rest position.
