| 摘要 |
The invention concerns a surgical needle comprising a crimping region (3) for fixing a suture (5) made of hyper-elastic alloy having, after treatment, two different states enabling to stress the needle in a substantially elongated position when it is housed in the internal bore (11) of a cannula or of an applicator (2) and when it is extracted from the cannula or the applicator to adopt an arc-shaped curved profile as a result of its own particular super-elastic or hyper-elastic properties, and the needle (1) comprises opposite the crimping zone (3) a tapered tip (6) provided with an inclined heel (7) arranged inside the curvature of the needle (1) and which is urged to be pressed against the internal wall of the bore (11) of the cannula or the applicator (2) to protect the tapered tip profile (6) when the needle is sliding inside the internal bore (11).
