Description

The invention relates to a device for supplying a stoma or its locking relative to the surface of a human or animal body. Moreover, the invention relates to the use of such a device.

Devices of the type mentioned are known in many ways in the prior art.

In the patent DE 10 2007 062 133 For example, it explains in more detail what is to be understood by a stoma, which forms are predominantly carried out according to the current state of medical knowledge, and which general aspects in connection with the wearing of a stoma are of importance. To avoid unnecessary lengths, reference is made in the present application to the aforementioned '2133 patent, in particular to the explanations regarding the so-called one-part or two-part restorations of stomata. As stated there, "the range of products for ostomy care ... is almost unmanageable."

Accordingly, the corresponding marketed products are based on various problems or solutions, in each case the provision of a hygienic, antimicrobial and low-irritation surrounding area for the abdominal wall and stoma is of primary importance. The mentioned patent '2133 In this connection, for example, it is the object, with the change of a so-called stoma pouch, to handle the outflow of smaller amounts of body exudates reasonably easily.

In the following, the older term "abdominal wall" is used instead of the more modern medical term "abdominal wall". As is known, an abdominal wall comprises various tissue layers, beginning with the outer epidermis and finally the peritoneum lying on the inner side of the body.

To a stoma z. B. to position relative to an abdominal wall in a stable manner, is in the patent US 5,269,774 (Inventor: M. Gray) proposed using an ostomy device which is proportionately composed of a kind of lattice structure. This lattice structure is an anchoring of the fabric fibers z. B. the abdominal wall, or those of the relevant body opening, allow. Further portions of the device referred to in the '744 are used to couple a suitable ostomy bag temporarily and interchangeably.

The present invention has for its object to improve the establishment and supply of a stoma, in particular an ileostomy or colostomy, by providing a suitable device.

For this purpose, as an important aspect of the invention, a device is specified, which is particularly suitable for significantly facilitating the surgically necessary interventions in the creation or modification of a stoma on the human or animal body.

Accordingly, the invention provides a device for locking and / or providing a stoma relative to the surface of a human or animal body, comprising a preferably one-piece central tube having a plurality of openings for anchoring renewable or existing intestinal tissue, a base plate suitable for attachment of an ostomy pouch and a locking cone for mechanically locking the base plate to the center tube, the locking being performed by a plurality of protruding elements corresponding to openings of the center tube.

In one embodiment of the invention, a mutually locked combination of base plate and center tube caused by securing cone has approximately hermetic sealing properties.

The plurality of openings may be arranged on the center tube in a repeating pattern to form adjacent groups of openings.

In a further embodiment of the invention, a ring nub is arranged in each case between adjacent groups of openings on the central tube.

In order to provide the said sealing properties, the central tube can be stretched radially in regions by the securing cone relative to a relieved state.

In a further embodiment of the invention, the securing cone on an annular groove, wherein a positive connection between a ring nub and annular groove by a regional radial expansion, based on a relieved state occurs.

A latching direction may be predefined from radially inward to radially outward from the groups of openings.

The openings on the central tube may be arranged in a circle.

In a further embodiment of the invention, the central tube on a support plate, which is adapted to support the central tube in the implanted state peritonal.

In a further embodiment of the invention, the base plate 105 connectable with an ostomy bag, preferably by clip connection, screw connection, bayonet connection, or adhesive connection.

In a further embodiment of the invention, the central tube ( 100 ) made of an elastic material, preferably silicone rubber and with tissue-compatible properties.

Furthermore, the use of a device in an opening of an abdominal wall of a human or animal body is indicated for test purposes.

In addition, the use of an ostomy pouch is provided with a device, wherein the ostomy pouch with the base plate 105 is connectable, preferably by clip connection, screw connection, bayonet connection, or adhesive connection.

According to the present invention, an ostomy appliance or a stoma restoration is provided, which consists proportionally of a kind of lattice structure. This should allow a sufficient, in particular then again relatively easily separable anchoring of the tissue fibers of the relevant intestinal section, if this should be required by surgery.

Moreover, it is essential concept of the present invention to use the existing grid structure not only for anchoring tissue fibers, but at the same time also to an effective and hygienic advantageous attachment of such an ostomy appliance or stoma supply relative to the abdominal wall (abdominal wall) or another To effect the body surface of a patient.

The device according to the invention is thus designed so that its lattice structure on the one hand allows or even allows anchorage of renewable or existing intestinal and / or abdominal tissue. On the other hand, by this lattice structure according to the present invention, an essential constructive element for attachment of the device to a body surface, for. B. an abdominal wall, provided.

The invention will be explained in more detail by means of embodiments with reference to the accompanying drawings.

In the drawings show:

1 a side view of a device according to the invention;

2 a side view of the device according to the invention 1 in longitudinal section;

3 a correspondingly enlarged and more detailed side view of the device according to the invention 1 in longitudinal section;

4 a correspondingly enlarged and more detailed side view of the device according to the invention 1 ;

5 a further side view in longitudinal section of the device according to the invention 1 ;

6 a further side view in longitudinal section of the device according to the invention 1 ; and

7 a cross-sectional view of the device according to the invention according to 1 a finished implanted device with schematically indicated tissue parts of a body.

As in the 1 to 7 As shown, the invention itself consists essentially of only three individual parts, namely a hollow one-piece central tube provided with preferably circular openings 100 with integrated support plate 110 , a base plate 105 and a safety cone 120 , Nevertheless, in practice, the device according to the invention would have to be completed with a commercially available ostomy bag (not shown). This is the art of the prior art on the base plate 105 flanged by clip connection, or possibly connected with a screw or bayonet connection. As in 1 shown are the base plate 105 and the support plate 110 on opposite sides along the central tube 100 arranged. Both the base plate 105 as well as the support plate 110 have a radially outwardly guided support element, which are designed in the embodiment shown as a ring. However, it is also conceivable to carry out the support elements as individual segments or the like, which project in the radial direction.

As shown in all figures, the center tube is 100 designed as a hollow cylinder of preferably about 50 to 80 mm in diameter. A variety of there systematically attached and already mentioned circular openings 102 (S. 3 ) extends circular in each case on levels, in the manner of floors, parallel to the support plate 110 ,

The illustrated arrangement of the plurality of openings 102 as circular holes is to be understood merely by way of example. It is also possible, for example, the openings 102 with a different outline such. B. triangular, rectangular or oval to design. Other alternatives known to those skilled in the art are of course not excluded. Furthermore, openings 102 be arranged in other than the systematic manner shown. For example, it would also be possible to have adjacent openings each arranged in the manner of floors 102 tangentially offset to arrange.

The central tube 100 is made of an elastic material, preferably silicone rubber of suitable hardness (eg SH 10 to SH 40) and with suitable tissue-compatible properties. The use of silicone rubber offers the advantage of simple, precise and relatively inexpensive production of this workpiece. When finished, it has a length of typically about 150 mm and can then be shortened at the moment of a medical operation to an individually required length.

The support plate 110 , integrally integrated with the central tube 100 is, for example, circular or elliptical, of suitable diameter, thickness and elasticity. On the one hand, it should serve with particular advantage to peritonal support the central tube in the implanted state, ie against the inside of the abdominal tissue layers, and thus to secure it from being pulled out. Such a problem is constantly posed by the weight of an externally attached stoma bag. On the other hand, it is intended to make the support plate so flexible that a problem-free surgical insertion of the central tube in the body of the patient is possible. Of course, if necessary, the operational removal of the central tube 100 be possible quickly and easily. The present invention solves this problem in comparison to the prior art much more advantageous.

The function and interaction of central tube 100 , Base plate 105 and safety cone 120 using the various existing ring-shaped knobs 104 (hereinafter referred to as ring nubs) will be described with reference to the other figures.

As in 3 is shown, for medical-surgical installation of a device according to the invention in addition to the central tube 100 with his ring nubs 104 first a base plate 105 needed. This is from the basic shape ago ring or hollow cylindrical and preferably also made of an elastic, tissue-friendly material such as silicone rubber o. Ä. Made. The outer dimensions of the base plate 105 are such as to ensure shape and function compatibility with at least one type of commercially available ostomy pouch. For this purpose, a suitable locking surface with suitably dimensioned locking edge 106 intended. In this way, it can be clipped there and with little effort a matching ostomy bag, although z. B. a bayonet or screw seems conceivable and can apply provided.

The outer edge of the base plate tapers conically up to the outer edge 107 which, after installation of the device according to the invention, mutatis mutandis lies on the epidermis of a treated patient, which therefore also applies correspondingly to the flat underside of the base plate shown.

As in 3 and further shown, the base plate 105 an annular groove 108 on, which is intended, a positive connection with one of the ring nubs 104 to enter, which, however, have to turn radially stretched. In the normal, vorspannungslosen state of the central tube, namely, its annular knobs have such an outer diameter that a base plate 105 without much resistance via an associated central tube 100 can be pulled until a desired distance between the support plate 110 and base plate 105 is reached.

As in 4 shown, so then a positive connection between a suitably selected ring nub 104 and ring groove 108 be achieved by the following: A likewise hollow cylindrical safety cone 120 is (in the view shown) from above into the combination of central tube and appropriately positioned, ie already proportionately positively connected base plate 105 introduced. Since the securing cone is dimensioned correspondingly larger in the radial direction, the central tube is partially radially expanded. There is thus a complete positive connection between ring knobs 104 and ring groove 108 like this in 5 and in particular in 6 is shown.

In 6 is also apparent that the safety cone 120 on the outside has a plurality of radially outwardly projecting elements. These correspond in shape and arrangement with any floor of the openings 102 , In this case, for example, the plurality of radially outwardly projecting elements in exactly the same number as the openings 102 be arranged on a floor. But it is also possible, less prominent elements than openings 102 to provide a floor.

The function of the above elements, hereinafter sealing knobs 122 called, is as follows. These correspond, as shown, in terms of shape and arrangement with any floor of the openings 102 , This allows the backup cone 120 specifically at a certain position with the central tube 100 be locked. The sealing knobs grip 122 completely in a selected plane (floor) of the openings 102 one. At the same time not only a mutual locking, but also a quasi-hermetic closure between base plate arises 105 and central tube 100 , including the safety cone 120 ,

Due to the elasticity of the intended items of the device according to the invention, it is also possible, if necessary, to solve a latched arrangement. For this purpose, it is necessary, the sealing knobs 122 from the corresponding openings 102 to press inward and remove the detented locking cone from the central tube, which is then unsecured, as well as the base plate 105 becomes separable.

From the foregoing it can be seen that the perforated, ie with openings 102 provided structure of the central tube 100 Thus, it is intended for several functions, namely on the one hand allows anchoring re-growing vascular tissue, and on the other serves to parts of a safety cone 120 absorb, thus providing a mechanical, mutual locking of base plate 105 and central tube 100 can take place in a secure manner.

The mechanical-biological relationship between the device according to the invention and tissue structures involved in the vicinity of an abdominal wall is described in 7 shown schematically. As can be seen, lies the base plate 105 on the abdominal wall 2 on and is already using a safety cone 120 and its sealing knobs 122 with the central tube 100 connected in locked and approximately hermetically sealed manner. Escaping from the stoma intestinal contents can only and then accidentally with removed stoma bag on the abdominal wall or abdominal wall 2 reach. A bowel section to be treated 1 and its associated stoma 3 are in about, as shown, mounted inside the central tube and there z. B. fixed by means of seam.

A particular advantage of the invention is that a possibly later to be carried out operational separation of intestinal section 1 and central tube 100 (For example, after healing of an inflammatory bowel process) would be easier to do than is possible according to the current state. This is due to the fact that both the radially inward and outboard surfaces of the central tube represented suitable guide surfaces along which a relatively simple operative separation of intestinal and abdominal wall tissue can be made.

In the following, the steps which are expediently carried out during an operative insertion of a device according to the invention are described below:

• - opening the abdominal wall 2 by cutting suitable contour and localization;
• - Insertion of the central tube 100 incl. support plate 110 in the abdomen;
• - Engaging the base plate 105 on the central tube 100 until it rests practically free of play on the abdominal wall;
• - Secure the latching of base plate 105 and central tube 100 by insertion of a safety cone 120 until its sealing knobs 122 in intended openings 102 snap;
• - Take out a relevant appropriate intestinal section 1 through the central tube 100 through to the outside;
• - Provide a terminal or double-stoma on this section of the intestine 1 ; and
• - Fix this intestinal section 1 at the central tube 100 by suturing and / or sticking, whereby the stoma concerned also via the central tube 100 can be put on.

It will be understood that according to the invention, after completion of the operation and first healing process, a mechanically matching, commercially available ostomy pouch for collecting and disposing body wastes may be clipped onto the baseplate, for example.
