DE202006015861U1 - Hook and loop type fastener used for suture-free wound adaptation in e.g. operating theater and subsequent healing, adheres hook strips to edges of wounds, and fixes them with bridging section - Google Patents

Abstract

Two hook strips (2) are attached by self-adhesive films on their undersides, to edges of a wound (1). The strips are of the hook-and-loop (velcro-type) variety. They are attached parallel to the wound edges, directly onto the skin. A bridging section is placed over the strips, to adapt and fix the wound edges. The bridging section is a suitable loop material. The bridging section may be interrupted, e.g. it comprises two pieces of loop material joined by a thread, several being used. A dumbbell-shaped connector is described.

Description

The The invention relates to a device for wound closure, the one Adaptation of wound edges and their subsequent Position correction without the use of conventional surgical sutures allows.

The classic surgical suture for desired primary wound healing not only carries a facultative risk of infection on each individual Puncture, from the further with high probability an undesirable scarring will result, but is also, especially among practitioners, the in this regard no regular routine have a time-consuming procedure. If required, delayed primary healing elevated the time required accordingly. Furthermore, in these forms of Wound care usually requires adequate anesthesia.

This problem was already recognized in 1899 in the patent DE-PS 1 11 345. The approach presented here, in which eyelets provided with eyelets are glued parallel to the wound edges, over which a wound edge adaptation takes place with a tensioning thread, was described later DE 695 07 314 T2 modified by the use of single patches to supply non-rectilinear wound courses. Both methods, however, require a time-consuming application.

The use of a hook - and - loop fastener over two plaster strips fixed to the edges of the wound and corresponding surfaces are used DT 24 18 603 A1 . DE 10137743 A1 and DE 4343671 A1 described.

In DE 43 35 432 A1 In analogy to the Wundrandadaptation by brackets a method is presented in which plasters are applied with interlocking longitudinal strips that are to be fixed by clamping on both sides of the wound.

The use of a zipper, which is fixed to plaster strips applied to the skin adjacent to the wound edges, is incorporated in US Pat DE 618393 A shown.

DE 2447681 A1 describes a Wundrandadaptation by magnets, which are mounted on parallel to the wound edges glued plaster strips.

All However, these methods involve in the event of a thread break, in the Remove cover sheet or staples or open the zipper or the magnetic connections for the purpose of wound care the risk a renewed Wundaufbruchs, since no further relief of the wound tension given is.

GB 2 083 753 A describes a wound closure in which several individual threads are fixed between two plaster strips. These are glued together in pairs parallel to the wound edges with the skin defect crossing thread course; the Wundrandadaptation is carried out by appropriate localization of the second patch strips and the resulting thread tensions. In DE 90 14 837 U1 This method is modified by two each bonded with a defined thread length adhesive body.

According to US 2004204740 AA a seamless Wundrandadaptation by parallel to the skin defect applied patch can be realized, which are arranged with opposite staggered, running at right angles over the wound and there to be bonded individual strips.

All these devices do not offer the possibility of subsequent correction of the wound margin distance, as required for delayed primary healing and secondary wound healing. DE 34 05 353 A1 meets this requirement by two individual patches connected with an adjustable thread.

In DE 101 53 012 C1 a flexible clamping dressing is described, in which the surfaces of the applied next to the wound edges plaster strips are provided with a grid, the crossing points have fastening means for holding tensioning threads. In the case of a thread break or the slipping of the thread from a point of attachment, the risk of a new wound is here also given.

DT 2262403 presents a method in which slideways and retaining straps fixed on plaster strips result in a closure that can be regulated in the wound edge distance in analogy to the functional mechanism of conventional cable ties.

The application of DE 101 53 012 C1 and DT 2262403 in the area of skin areas, which must fulfill sitting or lying functions, is in question.

With the ecxeption of DT 24 18 603 A1 . DE 10137743 A1 . DE 4343671 A1 and DE 43 35 432 A1 For all presented wound closures, additional coverage of the otherwise exposed wound surface is required.

Object of the present invention is therefore to provide a device for wound closure, which realizes an adaptation of wound edges without the use of conventional surgical sutures, the care of the wound and a Subsequent correction of the wound edge distance during delayed primary healing and secondary wound healing without renewed complete removal of the bandage is possible and minimizes the risk of a wound being broken.

These Task is inventively characterized solved, a hook tape provided with an adhesive film on its underside a Velcro on both sides parallel to the wound edges on the Skin is fixed. On this are monofilaments whose endpoints detention bodies Flauschband or a material with analog properties, attached at right angles to the wound. The cover of this Seamless wound edge adaptation is done by one with a gauze strip provided loop tape, from which an additional position assurance of each adhesive body results.

By a relief of the wound tension over several monofilaments and their self-sufficient fixation poses any risk of wound healing excluded when removing the cover dressing for the purpose of wound care.

A subsequent Wound margin adaptation for drainage removal, desired delayed primary healing or secondary Wound healing is through change the position of one or more adhesive bodies and / or their predefined Distance and the resulting thread tension feasible.

The intensity the Wundrandfixierung is thus no longer a constant thread train but can be customized in each wound area become.

By Gradual removal of individual fixations may further progressively Wound healing a controlled, until the final removal of the bandage slowly increasing wound load can be induced.

Of the here presented wound dressing can by appropriate cutting in size and shape to everyone Wundrandverlauf be customized.

in the Contrary to the classic suture is an anesthesia-free wound care possible, which also by medical Auxiliary staff can be done.

Of the Comfort of the presented wound dressing is one of conventional wound plaster comparable and is thus also used in the area of skin areas, the sitting or lying functions must meet, not as disturbing.

Optional can also by applying a sterilizable hook tape on the skin on both sides along the planned incision an operation the use of a surgical drape with appropriate Velcro trim, which ensures optimal position fixation, will be realized.

One embodiment The invention is illustrated in the drawings and will be described in more detail below. Show it

1 : Wound with hook band fixed to the skin parallel to the wound edges

2 : Adhesive bodies adapted by wound over a thread adapted wound edges

3 : Cover by gauze tape

An embodiment of the invention can be realized in that two or more hook tapes coated with an adhesive film on its underside (FIG. 2 ) of a hook and loop fastener on both sides parallel to the edges of a wound ( 1 ) are stuck to the skin.

at Not straight wound can transfer this on a transfer film and with their help, the hook tape cut in the desired shape become. Alternatively, a plate provided with a gap may also be used be used from hook tape.

The Wundrandadaptation is carried out by two adhesive bodies ( 3 ) made of a loop tape or a material with analogous properties connected by one or more threads; These are fixed at right angles to the wound. Alternatively, a dumbbell-shaped adhesive body whose web is stretched over the wound can be used.

A another embodiment the Wundrandadaptation is by adhesive body of a fly-screen-like Material feasible.

All mentioned adhesive body forms can optionally also irreversibly fixed with one end on the hook tape become.

at delayed primary healing or secondary Wound healing, the definition of the desired wound edge distance is carried out corresponding localization of the adhesive body. Alternatively, too predefined adhesive body distances in different lengths from whose selection the wound margin distance results.

A position correction of the wound edges to each other by changing the position of an adhesive body or Choice of another predefined Haftkörperdistanz feasible. In this regard, as a further embodiment, an adhesive body variant is possible which has a portion without adhesive function, which facilitates the lifting of the adhesive body.

The covering of this seamless wound edge adaptation takes place through a fleece band ( 4 ), which in analogy to a wound plaster with a gauze strip ( 5 ) can be provided. This results in an additional securing position of the individual adhesive body around them and in the use of adhesive bodies from a flyscreen-like material over these times.

A embodiment, in which the loop tape is fixed on the skin and the adhesive body as well The cover are made of hook tape, is identical with Functions realizable, but has a significantly reduced Wearing comfort.
