| 摘要 |
The invention concerns a medico-surgical cannula (1) comprising an axial channel (2) provided with a discharge orifice (3), a plurality of peripheral discharge orifices (4) and a proximal connector (5). The invention is essentially characterised in that the discharge orifices (4) emerge into the base of the grooves (6) provided at the periphery of the distal part (3) of the cannula channel (2). The invention is further characterised in that the grooves (6) are in spiral form and the channel (2) distal end (3) is tapered with decreasing cross-section from inside outwards. |
