CROSS-REFERENCE TO RELATED APPLICATION

[001] This application claims the benefit and priority of Patent for the Useful Model # 42539, filed in the Patent Office of Ukraine on February 11, 2009, titled "Device for Closing Surgical Wounds/' which is Registered in the Government Patent Registry for the Useful Models of Ukraine on July 10, 2009, the disclosure of which is hereby incorporated by reference.

BACKGROUND OF THE INVENTION

Field of the Invention

[002] The device belongs to the surgery branch of medical technologies and can be used for closing wounds in the process of various surgery procedures.

Description of Related Art

[003] The well-known Attachable Stirgery Suture Method (ASSM) is taken as a prototype (1). ASSM consists of a two-dimension base, which has a connective element between its parts. The base can be made out of, for example, a wide adhesive plaster or self-adhesive operational film or any other similar medical material. The element is tightly attached to the two-dimensional base which is split lengthwise into two parts with a lock on one end a catch on the other. There are connectors throughout the length of the element between the lock and the catch. They are opened and closed by means of the slider. The drainage holes can be placed on both sides of the connective element, the number or the presence of which depend on the length of the ASSM. They serve the purpose to let the drainage tube slide through, and for periodical disinfection of the wound. The edges of the two-dimensional base are covered by a protective film which is removed when it is applied to the skin tissue.

[004] ASSM, however, has the following disadvantages and limitations:

[005] 1. A straight tissue incision is a very difficult task to perform as the space between the lock, the catch and the two connectors is limited.

[006] 2. The presence of the lock on one end of the connective element and the catch on the other limits the length of the tissue incision to the length of the ASSM and does not allow to open the wound adequately wide during the operation.

[007] 3. The n-shaped connective element does not provide an ideal adaptation of edges of the wounds after the operation is completed and the slider is closed.

[008] 4. If the revision of the wound or the drainage process is necessary, one has to unzip the device. This can lead to the divergence of the edges of the wound throughout the whole length.

[009] 5. The ASSM could only be removed as an entire piece.

[0010] This model has to fulfill the task of creating a device that will provide an ideal straight tissue incision, will not create an obstacle, while opening the wound wider, will ideally match up the edges of the wound after the operation is completed, will let one, if necessary, perform a revision of the wound or the drainage procedures within a limited section of the wound and can be removed successively by detaching the separate elements.

SUMMARY OF THE INVENTION

[0011] Some exemplary embodiments comprise a device for closing a wound during surgical intervention, the device comprising a flat basis of two connected elongated plates. Both plates may be either non-porous or porous in order to improve skin ventilation and skin breathing. Pores in the plates may be of various shapes and sizes and the edges of the plates may have longitudinal sides in the zone of connection of the plates. The side of each plate in the zone of a plate-to-plate connection has a guiding element and there is a chamber along the connection of the guiding elements of the plates, which allows the penetration of a surgical instrument. Connective clips may connect the two elongated plates along the sides, and guiding elements provide the attachment and sliding of the clips.

[0012] Some exemplary embodiments comprise a method for making an incision and closing the incision during surgical intervention, the method comprising placing two elongated plates, which are attached to each other with the aid of connective clips, on at least a portion of a mammalian epidermal layer, removing a portion or all of the connective clips from the plates, making an incision in at least a portion of a mammalian epidermal layer, the portion of the mammalian epidermal layer located between the first elongated plate and the second elongated plate, expanding the wound to an extent, which is required to conduct a surgery, closing the wound by moving one or both of the elongated plates closer to the incision, and applying connective clips to connect the two elongated plates. BRIEF DESCRIPTION OF THE DRAWINGS [0013] FIG. 1 shows an exemplary device for closing surgical wounds.

[0014] FIG. 2 shows an exemplary clip.

[0015] FIG. 3 shows an exemplary clip relative to two exemplary elongated plates.

[0016] FIG. 4 shows an alternative view of an exemplary clip relative to two exemplary elongated plates.

DETAILED DESCRIPTION OF THE INVENTION

[0017] The device for closing surgical wounds is illustrated in Figure 1. The device comprises two two-dimensional elements (1), made of inactive polymers. The inner surface of each element has a self-adhesive layer (2), which is covered by the protective removable film (3) while the device is not in use. The internal edge of the plates in the connection zone is represented by the guiding elements (4) which are tightly connected to each other throughout the whole length. To ease the penetration of the blade of the cutting instrument (e.g., scalpel) between the plates, there are bevels (5) on the internal part of the upper edge of the guiding elements. A tight connection between the edges of the plates is achieved with the aid of the removable clips (6), which adhere to the guiding elements and which could slide along the guides. It includes separate connecting clips (7) being fastened on both sides by a thread made out of inactive polymers (8).

[0018] The usage of the proposed device is carried out in the following way. After the preparation of the operative field, the skin in the area of incision is thoroughly dried up with a sterile gauze cloth. The device is retrieved out of the package; the removable film is removed from the self-adhesive layer. The assembled plates are applied to the skin very carefully so that the connected edges of the guides match precisely the place of the future incision. The next step is to temporally remove the removable clips and to perform the incision. The incision is performed by sliding the blade of the scalpel between two guides. The length of the incision should either correspond to the length of the plates or it can be extended beyond the length of the plates at both sides. After the main part of the surgery is complete, the surgical wound is stitched layer by layer up to the subcutaneous fat layer, the edges of it are brought together and then the connecting clips are put in starting from one end. The connecting clips are moved along the guides towards the starting position. Thus, the tissue edges of the surgical wound are perfectly attached to each other and fixed.

[0019] In case when a temporary drainage of the subcutaneous tissue is needed, one should cut threads between two clips in the needed location, slide clips to the sides, and then, place the drainage device right in the opening. The "stitch removal" procedure is peeling off the plates from the surface of the skin. The device can be removed either as an entire block or by removing it piece by piece - first by removing the clips, and then by removing the plates one by one.

[0020] The benefits of using the described device for closing the surgery wounds are the following. The fact that the two-dimensional base splits into two parts allows one to perform the incision of the tissue without limiting the length of the cut by the elements of the device, thus the corners of the surgery- wound are released and can be opened wider adequately in the process of the operation. The bevels on the internal surface of the upper edge of the guides simplify the penetration of the scalpel blade between the plates, providing an ideally straight cut and fixed positioning of the cutting instruments perpendicular to the skin. The tight connection of the edges of the plates to each other, which is secured with the aid of the connecting clips, and to the skin tissue in the area of the surgical wound, provides the perfect connection of the edges of the wound.

[0021] If a necessity of a probe or a temporary drainage procedure arises, connective clips remain on the guides and prevent a dislocation of the edges along the device. The connecting threads are only cut at certain locations and the connecting clips are moved apart to the opposite sides, releasing a limited space for carrying out the procedure. Unique features of the proposed device allow to facilitate a process of "removal of stitches" because the device can be removed not only as an entire block but also by consecutive removal of its elements - first the connective clips, and then the plates one by one.

[0022] While various embodiments have been described above, it should be understood that they have been presented as an example only. Thus, the breadth and scope of a preferred embodiment should not be limited to any of the described exemplary embodiments.
