Definitions
- the present invention relates to an insertion device for an intra-urn pessary according to the preamble of claim 1.
- An object of the present invention is to provide an insertion device for an intra-uterine pessary, which allows the insertion of an intra-uterine pessary to be carried out more easily and safely.
- the insertion device accordingly u. a. a soft tip that can be made smaller than conventional systems. Due to the flexibility of the tip, it can more easily follow the curved shape of the uterus.
- Fig. La sleeve of an insertion device side view with partial section
- Fig. Lb top view of the rear end of the sleeve 2a trocar of an insertion device
- Fig. 2b section ge ass II-II m Fig. 2a
- Fig. 3a piston longitudinal section
- Fig. 4 extension tube side view
- FIG. 8 insertion device arrangement for inserting the sleeve m the uterus (side view, partially cut); and FIG. 9 insertion device while the trocar is being pulled out (side view, partially cut).
- the insertion device consists essentially of three parts: the sleeve 1 (Fig. 1), the trocar 2 (Fig. 2) and the piston 3 (Fig. 3).
- the piston 3 When ready for use, the piston 3 is connected to the pessary 5 to form a unit 18 (FIG. 5).
- the sleeve 3 corresponds to your dimensions (length, diameter) the known designs.
- the front (distal) end of the sleeve 3 has three small holes 6, each with a diameter of approximately 1 mm, in order to reduce the piston effect when the trocar 2 is pulled out, in that the resulting negative pressure is also compensated for via the holes 6.
- the rear (proximal) end of the sleeve is designed as a sleeve 20. It has a funnel part 12.
- the funnel 12 m connection with the rounded transition 21 simplifies the attachment of the extension tube 4 (see FIGS. 4 and 6).
- the open end of the funnel 12 is one flat support surface 57 and an orientation aid 40.
- the sleeve tube 54 is provided with a centimeter scale 55.
- the centimeter scale is used with the help of
- the marking tube 9 to be able to determine an exact insertion depth of the sleeve 1.
- the marking tube 9 (FIG. 7) consists of two rings 22 which are connected to one another by rigid bridges 23, preferably two.
- a handle 11 is located on the rear ring 22.
- the tip 29 of the trocar 2 (FIG. 2) essentially consists of the head 34, the neck 35 and the belly 36.
- the tip 29 is essentially conical overall, slightly bent towards the head 34 and rounded at the head 34.
- the belly 36 lies opposite the orientation aid 41.
- the tip 29 consists of two components of different elasticity, namely a stiffer core and a softer outer part.
- the two components can e.g. B. consist of two different silicones.
- the tip 29 is overall softer or more elastic than the rest of the trocar 2, in particular its shaft 59. B. made of polyethylene.
- the handle part 61 of the trocar 2 consists of the actual handle 16 and in front of it a shield 63 which has a support surface 13 towards the shaft.
- On the side of the shield is the orientation aid 41.
- the trocar 2 can be inserted into the sleeve 1, the surfaces 12 and 13 on the sleeve 1 and on the trocar 2 coming to lie on one another and the orientation aids 40 and 41 being aligned with one another. This makes it possible to recognize the orientation, particularly of the tip 29 of the trocar 2, while the sleeve 1 is inserted into the uterus with the trocar 2 inserted.
- the tip 29 of the trocar 2 protrudes with the length of the arms 65 of the pessary 5 from the sleeve 1 (FIG. 5).
- the tip 29 must be somewhat longer overall, e.g. B. by approx. 3 mm, so that the rear end 14 of the tip 29 is still in the sleeve tube 54.
- the rear end thus acts as a stabilizer for the tip and the trocar shaft 59 in the sleeve tube 54.
- the trocar 2 additionally has three wedges 15 at the rear end, which also stabilize the shaft 59 in the
- the wedges are arranged at an angle of 120 ° to each other.
- the extension tube 4 (Fig. 4) for the piston 3 consists of the same material as the sleeve 1 (polyethylene). It can be inserted tightly m the sleeve 20 of the sleeve 2.
- the inside of the tube 44 has the same diameter as the sleeve tube 54, so that the tubes merge smoothly into one another and the spiral 5 can be easily inserted into the sleeve 2 from the extension tube 4 m.
- the piston 3 Because of the part 46 of the extension tube 4 which extends the sleeve 2, the piston 3 must be made longer by the length of this part than the pistons for the known designs with sleeves.
- the extension tube is provided with a conical ring with a bearing surface 17 and an orientation aid 43.
- the support surface 17 is formed on the
- the orientation in the sleeve 2 is determined by aligning the orientation aid 41 of the sleeve 1 and the orientation aid 19 of the extension tube 4.
- the extension tube 4 receives the spiral 5 and the end 67 of the piston 3. It protects the spiral (the pessary) in particular both mechanically and against contamination, e.g. B. contact with the cervix is avoided and the insertion of the spiral 5 m facilitates the sleeve 2.
- the piston 3, the extension tube 4 and the pessary 5 form a unit 18 (FIG. 5). It is best gripped by the handle 19 of the extension tube 4 and the piston at the point 18 near the opening of the extension tube 4.
- the piston 3 is provided near the piston end 67 with three wedge-shaped stabilizers 24 arranged at an angle of 120 °. In the ready-to-use configuration, the stabilizers 24 support the piston against the extension tube 4 and thus stabilize it.
- the piston 3 Since the piston 3 has to slide over the thread 27 of the pessary 5 when it is pulled back, it has no sharp edges. At the rear end with handle 69 there is a thread tensioner 25 to hold the thread 27 in place. Otherwise, the piston 3 corresponds to the known designs.
- the trocar 3 is pushed into the sleeve 1 until the surfaces 57 and 13 lie on top of one another (FIG. 8).
- Orientation aids 40 and 41 are aligned precisely with one another.
- the marking tube 9 is measured to the length of the previous one Sounding of the uterus stopped. The length is measured from the end of the tip 29 of the trocar 2.
- the unit 38 consisting of trocar 2 and sleeve 1 is pushed through the cervical canal as far as it will go into the uterine floor (fundus).
- the soft tip 29 ensures that the front end of the unit 38 can easily follow the shape of the uterus. Injuries to the uterine wall are also avoided. If necessary, the advancement can take place with slight rotary movements, but the surfaces 57 and 13 must always be held together.
- the marking tube 9 is withdrawn by the length by which the tip 29 has protruded from the sleeve 2, for. B. 20 mm.
- the sleeve 1 is now pushed again until it stops, the marking tube 9 coming into contact with the cervix when the sleeve 1 is in the correct position in the uterus and thus represents an additional possibility of control.
- the unit 18 (piston 5, extension tube 4 and pessary 5) is inserted into the sleeve 1 so that the surface 17 abuts the surface 57 and the orientation aids 40 and 43 are aligned with one another (FIG. 6).
- the orientation aids then together form a handle 30 which serves to pull out the entire unit 37 thus formed.
- the sleeve / trocar unit 38 (FIG. 8) is inserted into the uterus up to the stop m.
- the trocar 2 is removed and the spiral / piston unit 18 is attached to the sleeve 1.
- the piston 3 is advanced until the unfolding of the arms of the spiral 5 can be felt.
- the piston 3 is advanced and held until it stops.
- the thread 27 is released from the thread tensioner 25. Then the sleeve 1 and then the piston 3 is pulled out.
- Piston 3 and sleeve 1 are pushed together as far as they will go.
- the thread 27 is loosened, and the sleeve 1 is withdrawn with the piston 3 held in place, and then the piston.
