Definitions
- the present invention relates to a percutaneous or transcutaneous connection arrangement according to the preamble of claim 1, and uses of the arrangement, and a method according to the preamble according to claim 12.
- Percutaneous access leads mechanically through the skin.
- Transcutaneous approaches actually have no mechanical access. They are often based on the induction principle and thus establish an electrical connection between the inside of the body and its external surroundings.
- Wo98 / 51367 and also WO 99/34754 propose purely mechanical plug connections for connecting and disconnecting the access in front. Since a minimal contact pressure is required at the connection point for both electrical feeds and the administration of fluids, the constructions are relatively complicated and the plugging and unplugging becomes cumbersome for the operator. In contrast, US 5 '507' 303 suggests, among other things, that the necessary contact pressure is generated magnetostatically. A magnet is installed in both the implanted part and the pluggable part, which ensure the contact pressure. However, the guidance and alignment of the outer part relative to the implanted part of the access is done mechanically.
- transcutaneous connection which consists of a pair of flat symmetrical coils which are aligned with one another with a pair of cylindrically symmetrical permanent magnets. This latter arrangement is also relatively complicated and not user-friendly.
- the percutaneous or transcutaneous accesses to the inside of the body proposed according to the invention use magnetostatic forces, both to ensure the necessary contact pressure as well as for alignment and Position the outer part of the access relative to the implanted part. This creates a connection that is much easier to handle for the operator.
- the positioning can be facilitated in that the permanent magnets used are asymmetrical, for example elongated. North resp. South poles of the magnets do not follow the inside of the body as in US 5 '507' 303, but along the body opening. In other words, the permanent magnet with its poles runs parallel to the body skin.
- connection between the inside of the body and the surroundings of the body has an inherent asymmetry. This is the case, for example, if the number of individual executions cannot be arranged symmetrically with a percutaneous connection. Such a case also exists if two asymmetrical flat coils of a transcutaneous connection should be aligned with one another.
- FIG. 1 shows a percutaneous connection with two individual bushings in a longitudinal section
- FIG. 2 shows the top view of the magnets, shown in Figure 1
- Figure 3 is a schematic representation of a transcutaneous connection with two flat physiologically shaped coils in the area of the outer ear.
- Figure 1 shows in longitudinal section a percutaneous connection with two individual feedthroughs, this connection being formed in two parts.
- One part 5 is formed by a permanent magnet 7, which is arranged below the epidermis 1 in the area of the dermis or a bone 3 lying below the epidermis.
- N and S the north and south poles of the permanent magnet 7 run through the permanent magnet.
- Two bushings 9 are formed, each with a widened opening 11, which protrude slightly from the epidermis 1.
- this is a design of the bushings, for example, and only one or more bushings can be provided, and these bushings do not necessarily have to have an enlarged opening 11.
- an outer plug-in part 15 is provided, which in turn has a permanent magnet 17, comprising a south and a north pole, denoted by S and N. From a supply or removal line 19, which is, for example, a flexible hose can act, run two
- Lines or two accesses 21 through the permanent magnet 17, again each having a connection opening 23 facing the openings 11, for example suitable around the outer part 15 onto the two openings 11 shallstecken.
- snap-in elements or other holding members can be provided if the force of the two permanent magnets is not sufficient to hold the outer part 15 on the permanent magnet 7.
- the lines both in the implanted part 5, as well as in the outer plug-in part 15, are both suitable for supplying any substances such as medicines, nutrients and the like, as well as for removing liquids in particular from the inside of the body
- FIG. 2 the top view of the permanent magnet 7 is shown from the outside, the permanent magnet 7 and the dermis or the bone 3 running under the epidermis becoming visible by omitting the representation of the epidermis 1.
- the two bushings 9, which run perpendicularly through the permanent magnet 7, are clearly recognizable.
- the elongated, oval-shaped permanent magnet in FIG. 2 can of course be designed differently, for example rectangular, rod-shaped, etc.
- FIG. 2 again shows a top view of the outer plug-in part 15, consisting primarily of the permanent magnet 17 and the accesses or lines 21, which are intended to be pluggably connected to the bushings 9.
- the outer magnet 17 uss is not elongated oval, but can be adapted to the shape of the permanent magnet 7, be designed differently. Yes, it is even possible to arrange a coil in the outer part 15 to produce one
- FIG. 3 finally shows a possible application of the arrangement proposed according to the invention in the form of a transcutaneous connection with two flat, physiologically shaped coils in the region of a human ear 31.
- the implanted part 25 of a transcutaneous connection has a coil 27 which is suitable for receiving or for transmitting electrical signals and or for transmitting electrical energy.
- the implanted part 25 also has a permanent magnet 29, which is used to align and fix an outer part with respect to the implanted part. This fixation may be necessary in particular if the coils are not current-carrying. Both the coil 27 and the permanent magnet 29 are implanted under the skin and are not visible from the outside.
- Figure 3 shows this arrangement, with the omission of the representation of Epidermis over the implanted part, this was made visible.
- the outer part (not shown here) of the transcutaneous connection likewise has on the one hand a coil for the transmission of signals and / or energy and on the other hand a permanent magnet for positioning and fixing.
- the area of the outer part of the connection facing the implanted part has materials and a surface which are skin-friendly and comfortable to wear.
- the pair of permanent magnets is designed in terms of geometric shape and magnetic strength so that the outer part of the connection aligns and positions optimally over the implanted part as soon as it is brought close to the implant. The alignment is optimal when the inductive coupling between the coils is at a maximum with the geometric shape determined by the anatomy.
- the positioning and holding action of the permanent magnets is also effective in this transcutaneous arrangement, since the magnetostatic field also acts through the skin.
