PERTUBATION ADAPTER FOR CHECKING THE TUBULAR PIPE

MOBILITY

The invention relates to a pertubation adapter according to the preamble of claim 1.

The fluid used is either carbon dioxide gas to blow through the fallopian tubes or a Body-compatible rinsing liquid used. To this For this purpose, the uterus is sealed airtight by applying a so-called portio adapter to the portio. The well-known portio adapters consist of a suction bell that surrounds the portio and which, by means of a light Vacuum is sucked on the portio, and one

Portio cone attachment arranged within the suction bell, which is inserted into the cervical canal and closes it off to the outside due to its conical shape * At the distal end of the portio cone approach is a mostly curved probe with one or more openings for the supply of the Fluids attached to the uterus.

This probe must be inserted before the fluid is introduced through the cervical canal. Your arched curvature corresponds to the anatomical conditions, so that the examination of the fallopian tube patency does not dilated uterus can maintain its normal position.

To avoid injuries to the cervical canal, it is necessary to insert and guide the probe into and through it through the cervical canal an exact attachment of the portio adapter to the portio. However, as the probe is inserted into the cervical canal only to a limited extent, despite the vagina being somewhat stretched by the introduction of the specula Extent can be observed visually directly and, moreover, to a considerable extent through the suction cup of the portio adapter is covered, the suction bell is made of a transparent plastic in a known portio adapter prepared. However, the material-related surface reflections restrict the view through the transparent one Suction cup in such a way that it is sometimes not possible to recognize the orificium uteri externum.

The invention is to provide a Pertubatxonsadapter to be created when the probe is inserted into the Cervical canal a good direct visual observation of this process without visual obstruction and disturbing Allows reflexes.

In the case of a perturbation adapter of the type mentioned at the outset, this object is achieved according to the invention by the characterizing features Features of claim 1 solved.

By dividing the perturbation adapter into two parts according to the invention In a probe part and a suction cup part that can be pushed onto it, it is possible to initially use with full view of the portio, insert the probe through the vagina into the cervical canal until the Orificium uteri externum through which partially into the cervical canal penetrating portio cone approach is closed. Subsequently, the suction cup part is on the proximal Open the end of the inner tube on the probe part. bx5 die oäüyylOCke 5Π uBjT FOITtiO ΖϋΓ ÄHj.5gG comes. During this process, the proximal end of the inner tube passes through that at the proximal end of the encompassing one Rohrs attached ring seal through, whereby the inside of the suction cup is sealed to the outside.

When moving the probe part and the suction cup part, it should be avoided that the next The vacuum line opening into the suction cup through the tube by placing the proximal end of the cervical cone attachment too tightly is relocated. This can be done in various ways, for example also by a corresponding one proximal recess of the cervical cone approach, but preferably by a stop according to claim 2, the is expediently formed in the shape of a ring web, achieved will.

A preferred exemplary embodiment of the invention is explained in more detail with the aid of the figures. It shows:

which passes through the proximal end 22 when the tube 24 is pushed onto the inner tube 20.

As a result of the separate handling of the probe part 10, the probe can initially be under direct visual observation 14 through the cervical canal into the uterus until it is closed of the orificium uteri externum through the portio cone attachment 18 introduced and only then the suction bell texl 12 on the inner tube 20 until it is in contact the suction bell 26 can be pushed onto the portio. Then the suction cup part 12 is easily attached to the Portio pressed and through the supply line 34 generates a slight negative pressure in the suction bell 26, whereby the Suction bell is sucked into the portio. Then the fluid used in each case can through the inner tube 20 in the Probe 14 and introduced through the openings 16 into the uterus will.

To simplify matters, it is of course also possible to partially push the suction cup part 12 onto the inner tube 20 before the probe 14 is inserted into the uterus and to generate the slight negative pressure in the suction cup 26 at the same time. The distance of the suction bell 26 from the distal end of the probe 14 can then still be so great; ^u will hold that good visual observation is possible in the introduction by the Zervixkanäl in the uterus. After the probe has been completely inserted, the suction bell 26 then only has to be pushed up to the portio, where it is sucked in and fixed as a result of the negative pressure.
