  • the present applicator is then provided with a distal portion (10) of smaller diameter than the proximal portion (20), advantageously to form a radial undercut (21).
  • the bulged tip (11) is first inserted into the vaginal canal of the patient until the cervical region is found.
  • the tip (11) of the applicator is inserted into the sequence in the narrowed endocervical canal. In this way, this tip is advantageously bulged so that it can be introduced into the narrowed and narrowed cervical canal.
  • the applicator is further provided with a proximal portion (30) which functions as a handle for the surgeon's handling.
  • This proximal portion (30) is preferably larger in diameter than the portion (20) medial.

Abstract

Le présent modèle d'utilité concerne le domaine médical, et notamment un applicateur d'un dispositif dilatateur (40) pour son introduction dans le canal interne du col de l'utérus. Le dispositif dilatateur (40) comprend un disque (43) doté d'un orifice (42) central à travers lequel s'étend un conduit (41). L'applicateur comporte une partie distale (10) présentant une pointe (11) convexe, une partie incurvée (12) et une partie droite (13). Le dispositif dilatateur (40) est inséré dans l'applicateur par introduction de la pointe (11) dans l'orifice (42) du dispositif dilatateur (40), la partie distale (10) de l'applicateur traversant le conduit (41) jusqu'à ce que le disque (43) du dispositif dilatateur (40) arrive au niveau de l'épaulement (21), le dispositif dilatateur (40) restant alors positionné sur la partie droite (13). La partie médiane (20) possède un diamètre plus grand que celui de la partie distale (10) et une longueur supérieure à celle du canal vaginal. La partie médiane (20) est raccordée à une partie proximale (30) servant de câble en vue d'une manipulation par le chirurgien.
