An inserter

Abstract

The present invention relates to an inserter for an intrauterine system, comprising a handle (3) having a longitudinal opening (8) at its first end, said opening (8) having a longitudinal axis parallel to the longitudinal axis of the inserter, a first end (8a) and a second end (8b), a movable slider (5) arranged in said longitudinal opening (8) and having a first end (5a) and a second end (5b), a plunger (2) attached to the handle (3) and having a longitudinal axis, and an insertion tube (6) having a first end, a second end and a longitudinal axis essentially parallel to the longitudinal axis of the plunger (2), the insertion tube (6) being, along said longitudinal axis, movably arranged around the plunger (2). The invention is characterised in that it further comprises a flange (4) arranged on the insertion tube (6) at its first end, and means for locking the slider (5) into a position showing the correct insertion depth for the intrauterine system, said means being adjustable with respect to the opening (8) of the handle.

Description

[0001]The present invention is related to an inserter for positioning an intrauterine device or an intrauterine system in the uterus.BACKGROUND OF THE INVENTION[0002]Various types of inserters have been developed for the positioning of mechanical and copper wire-containing intrauterine devices (IUDs) as well as of intrauterine systems having a drug containing cylinder (IUSs). In the following, IUD and IUS can be used interchangeably and when one is mentioned, it is to be understood that either of them can be used.[0003]Most common inserters are constructed for introducing the device into the uterus in a contracted state. These inserters usually comprise an insertion tube having a relatively narrow diameter and a rounded, blunt end which will pass through the cervical canal easily and will not damage or injure the fundus upon contact therewith, and a plunger inside the insertion tube. Prior to insertion the device, whether an IUD or an IUS, is usually retracted into the insertion tub...

AI Technical Summary

Benefits of technology

[0008]An object of the invention is to provide a simple, easy to use inserter for the positioning of an intrauterine system in the uterus by solving at least partially at least some of the problems mentioned above. An object of the invention is particularly to provide an inserter having an improved system for securing the simple and correct positioning of the intrauterine system in the uterus.

Problems solved by technology

With these inserters the correct positioning and a secure attachment of an IUS or IUD on the inserter as well as a proper handling of the removal strings may be difficult.
