The present invention relates to a puncture apparatus (1) for the surgical treatment of the female urinary incontinence. The puncture apparatus comprises a rotatable puncture member (3). Said puncture member has a puncture needle (31) comprising a needle tip (312) an interlock portion (32) and an axial portion (33). The puncture apparatus further comprises a urethral-insertion member (4) having a longitudinal shape and a supporting member / restriction means (2). The supporting member restricts the positional relation between the puncture member and the urethral-insertion member such that when the puncture member moves rotationally and punctures the living body tissue, the needle tip passes far lower than the longitudinal axis of the urethral-insertion member. The puncture apparatus may further comprise a vaginal-insertion member (5).La présente invention concerne un appareil de perforation (1) pour le traitement chirurgical de lincontinence urinaire chez la femme. Cet appareil de perforation comprend un élément de perforation rotatif (3). Ledit élément de perforation comprend une aiguille de perforation (31) comprenant une pointe daiguille (312), une partie dinterverrouillage (32) et une partie axiale (33). Cet appareil de perforation comprend en outre un élément dinsertion urétrale (4) de forme longitudinale et des moyens support/de restriction (2). Lélément de support limite la relation de position entre lélément de perforation et lélément dinsertion urétrale, de telle sorte que lorsque lélément de perforation se déplace en rotation et perce le tissu de corps vivant, la pointe de laiguille passe beaucoup plus bas que laxe longitudinal de lélément dinsertion urétrale. Lappareil de perforation peut en outre comprendre un élément dinsertion vaginale (5).
