Skin Closure Device for Surgical Procedures

The present invention constitutes an important advance and improvement over the constructions shown in prior U.S. Pat. Nos. 3,863,640, 3,933,158, 4114,624, 4,531,521 and 4,976,726. The construction shown in the last to issue of Applicant's patents is the closest construction to the present device but has disadvantages that are overcome by the present device. For example, the prior device is adhesively attached to the skin over the whole area of the skin closure device and therefore, when the incision is made by cutting through the member, any stretching or pulling will produce a stretching and pulling difference between the skin closure device and the adjacent skin and this can result in body fluids filling the cracks and crevasses in the device especially in the areas adjacent to the incision, and this can make for an unsightly appearance, possible infection and can possibly result in slowing down the healing process. These disadvantages are overcome by the present construction which has a non-adhesive portion which extends along the incision on both sides and therefore has a folding back ability which means that once the surgery is completed or even during the surgery, the surgeon can clean the area along the incision as required without having to stretch or pull the portion of the skin closure device that is attached to the skin. This has important advantages over what has been done before.

The present invention resides in a skin closure device which is relatively easy to use, provides greater access to the skin of the patient in the area where an incision is to be made or has been made, and it also provides the surgeon with the ability to locate the bandage accurately before it is even attached to the skin by for example, making a line on the skin where the incision is to be made and making a corresponding line on the portion of the skin closure device that does not have adhesive on it so that the surgeon can align the two lines adjacent one other before making the incision. Thereafter when the incision has been made the portions of the skin closure device adjacent opposite sides of the incision will not be adhesively attached to the skin and therefore can be moved or folded back for cleaning purposes or for other purposes or for other purposes including for helping the healing process by not adhesively attaching anything to the skin adjacent to the incision. This also means that surgical staples, sutures or the like can also be used by attaching to the skin where necessary. The subject construction also makes it possible after the incision is closed by means of adhesive bridging members to have a strip with medication in it attached along the area of the incision.

The present construction also lends itself to use with a surgical drape which is a sheet of material that is spread over the body of the person being operated on. The surgical drape has a window which is located in the area where the surgery is to take place. The subject skin closure device can be attached to the surgical drape prior to or after the surgical drape is positioned on the patient and various means can be used to make this attachment. For example, the subject skin closure means can be attached using VELCRO, hook and loop fasteners, it can be attached by zipper means or snap fastener means, it can even be attached integrally with the surgical drape, and it can be attached to the body of the patient prior to applying the surgical drape to the patient. When the surgery has been completed and the skin closure means are closed, the surgical drape can be removed as by disconnecting it from the skin closure means. This can be done by cutting it loose, unzipping it, separating the VELCRO, the hook and loop fasteners or unsnapping it. It can therefore be seen that the present device offers the surgeon many different options for surgery, all of which are easily performed and easily understood.

It is an object of the present invention to provide improved means for closing an incision.

Another object is to enable a surgeon to clean the skin area adjacent to an incision prior to closing the incision.

Another object is to provide a skin closure device that is particularly well suited to surgery and which enables the surgeon to clean the wound area without having to pull anything that is adhesively attached to the skin.

Another object is to enable any length of a skin closure device to be used and enable the surgeon to cut off as much or as short a skin closure device as is necessary for a particular procedure.

Another object is to provide relatively inexpensive easy to use means for closing an incision.

Another object is to give a surgeon more options as to how to close an incision made during surgery.

Another object is to enable a surgeon to close a skin opening in a manner that will be more comfortable and better looking than has been possible heretofore.

Another object is to enable a surgeon to bring the skin edges adjacent opposite sides of an incision into alignment while retaining the skin portions adjacent to the incision in a more comfortable aligned condition.

Referring to the drawings more particularly by reference numbers, number 20 in FIG. 1 refers to a skin closure device constructed according to the teachings of the present invention. The skin closure device 20 includes a flexible sheet member 22, that has adhesive areas 24A and 24B on one side surface. In the construction as shown in FIG. 1, the adhesive areas 24A and 24B extend to adjacent opposite sides of a non-adhesive area 26 which is positioned between the adhesive areas 24A and 24B along the length of the device. A cover member 28 is shown adhesively attached to the member 22 by means of the adhesive areas 24A and 24B. The closure member 28 is removed from the device 20 prior to use by applying it to the surface of the skin of a person such as a person who is to undergo surgery. Accurately locating the subject device on the skin is important to most surgical procedures as will be explained. The member 22 should preferably be relatively flimsy to conform to the contours of the skin.

Referring to FIG. 2 it can be seen that the subject closure device 20 has the cover member 28 removed and the adhesive portions areas 24A and 24B are positioned to be placed on the skin of the person to be operated on with the non-adhesive area 26 positioned such that the incision to be made by the scalpel 30 can be made through the non-adhesive portion thereby leaving an area adjacent to each opposite side of the incision where the member 22 is not adhesively attached to the skin.

FIG. 3 shows the subject embodiment 20 after the incision has been made with the non-adhesive areas 26 shown raised off the skin 32 along the incision 34 so that the areas adjacent to the incision are not subject to being restrained by the adhesive. This makes for less pulling of the skin by the member 20 and enables the surgeon to better control the operation in a manner more like usual surgery made directly into the skin and not through a skin closure device such as the present device. This also enables the surgeon to move the skin more easily without stressing the skin or the skin closure, and the width of the non-adhesive portion 26 can be varied depending upon the type of surgery to be performed and the amount of unrestrained movement of the skin that is desired. Once the surgery has been completed, the surgeon can again move the portions of the skin closure along opposite sides of the non-adhesive area 26 to a folded back condition so that the skin along opposite sides of the incision and along the non-adhesive portion 26 can be cleaned prior to closing the incision. In the folded back condition it is also possible for the surgeon to apply staples or sutures, subcutaneously or at the surface of the skin, to further close the incision prior to closing the subject skin closure over the incision. If desired, the non-adhesive portion 26 can be formed by attaching a member such the dotted member 26A (FIG. 1) that is non-adhesive but is adhesively attached to the member 22 in the area between the adhesive areas 24A and 24B and can optionally be removed at the conclusion of surgery so that the surgeon can if desired adhesively attach the entire surface of the member 22 to the skin even extending up to the edges of the incision.

Once the surgery has been completed and it is time to close the incision, the non-adhesive surface area 26 can be moved downwardly adhesively or non-adhesively as desired into engagement with the skin, and the opposite edges of the incision and the skin closure device can be brought together and held together by means such as by adhesive strips 36 which are strips of a plastic or plastic-like material with an adhesive on them. One form of the strips 36 is shown in FIG. 4. Markings 38 on the device can also be aligned during closure to improve the result.

One of the advantages of using strips 36 or like members including others that will be described later, is that there will be some spaces provided between the adjacent adhesive members 36 and the surface of the closure member 22 along the incision 34, and these spaces enable a member such as a foam member with a medication in it to be adhesively attached to the device along the incision so that the medication can seep into the space between the skin closure member and the incision to prevent infection and to aid the healing process. Such a strip is disclosed in U.S. Pat. No. 4,976,726.

FIG. 5 shows another way to use the subject device which has certain advantages that have been accepted in modern day surgery. FIG. 5 shows a flexible surgical drape 40 with an opening 42 at an intermediate location where surgery is to take place. The surgical drape protects the body of the patient and also provides the window 42 into which, or beneath which, or above which, the subject skin closure device can be positioned and attached if desired. The drape prevents the spread of body fluids about the patient's body and also provides some protection for the subject skin closure device. The manner in which the skin closure device is attached or installed in the window 42 can be as described above and at the conclusion of surgery when the incision has been closed, the surgical drape 40 can be removed and/or detached leaving the patient in a clean, yet surgically correct, condition.

FIG. 6 shows an embodiment 48 of the present device wherein two separate portions 50 and 52 of the subject skin closure device are adhesively attached to the skin 53 prior to surgery. The incision is made between them so that when the surgery is completed the two members can be brought together into adjacent or substantial alignment with the edges of the incision. The members 50 and 52 have adhesive portions 53 and 54 similar to the portions 24A and 24B which are attached to the skin and non-adhesive portions 56 and 58 which are not adhesively attached to the skin. The portions 56 and 58, as in the previous example, can be formed by having non-adhesive cover members 60 and 62 which can be removed to enable them to be adhesively attached to the skin along opposite sides of the incision, if desired.

FIG. 7 shows an embodiment 70 of the subject device which is similar to the embodiment 20 shown in FIGS. 1-4 but uses elongated flexible closure straps 72 which are flat straps with an adhesive on one side surface and a non-adhesive opposite surface. Except for this difference, the construction shown in FIG. 7 is similar to and is used similarly to the constructions described above.

FIG. 8 shows an embodiment wherein the closure member 80 has an adhesive covering the lower surface except for the outlined area 82 which may be non-adhesive or may be a non-adhesive member attached adhesively to the surface of the member 80 at the location shown. With this construction, the incision (not shown), which may be short, can be made through the member 80 in non-adhesive area 82 but generally will not extend across the full length of the member 80. This construction enables the portion of the non-adhesive area 82 to be slit at an angle adjacent opposite ends of the incision as at 84 and 86 to facilitate moving it from the closed to the open condition. Except for this difference, the construction shown in FIG. 8 is similar and operates similarly to the constructions described above.

FIG. 9 shows an embodiment wherein the closure member 90 has an adhesive layer on the lower surface thereof, and the adhesive is covered over by three separate members 92, 94 and 96. The members 92 and 94 are located to extend to adjacent opposite side edges 98 and 100 of the member 90 and the member 96 covers the adhesive in the area between the members 92 and 94. The construction shown in FIG. 9 can be made in any desired length or width and can be rolled up for storage as shown in FIG. 11 and unrolled so that the surgeon can cut off appropriate lengths as needed.

FIG. 10 shows the same device 90 shown in FIG. 9 in position wherein the non-adhesive cover layer 92 is being removed from the adhesive on the member 90 therebelow. The similar cover member 94 can also be removed in a similar manner as can the cover layer 96, if used. However, the cover layer 96 will usually remain in place until after the incision has been made and the surgical procedure completed. At that point, the surgeon can make up his mind whether he wants to adhesively reattach the portion of the adhesive layer covered by the member 96 or whether he prefers not to do that in the manner indicated above. The cover members 92, 94 and 96 each is shown having a tab 92A, 94A and 96A to make it easier to get a hold of them.

FIG. 11 shows a roll 110 formed as described in connection with FIG. 9.

FIG. 12 shows a piece of the subject skin closure device located above an arm 120 which has a line 122 inscribed at the location where an incision is to be made. A similar line 124 is drawn or otherwise applied to the skin closure device at the location where the incision is to be made. If the closure device is formed of a transparent material, the lines 122 and 124 can be positioned in alignment with each other to facilitate installing the skin closure device in the desired position. Once this is done, the surgeon can make the incision through the device where the aligned lines 122 and 124 are positioned.

FIG. 13 is an exploded view showing an embodiment 130 of the subject device installed on the skin of a patient. The device as shown has two flaps 132 and 134 which are folded back. The flaps 132 and 134 are non adhesive or are covered with non adhesive cover layers. The device 130 also has connected end portions 136 and 138 which together with the inner edges of the flaps 132 and 134 define the area of the skin 140 where the incision 142 is located. The incision in this case is shown closed by surgical staples 144 which is possible with the present construction because there are no adhesive parts that extend up to the incision. The flaps 132 and 134 can be brought together and laid on the skin extending up to the incision 142. After this is done, a medication strip 146 can be placed on the closed flaps 132 and 134. The medication strip 146 can be adhesively attached or can be positioned and held in place as by placing a gauze member 148 thereover. If the gauze member 148 is used it can be attached and held in place by adhesive strips 150. It is also contemplated with the construction shown in FIG. 13 to hold the closed flaps 132 and 134 in a closed condition using elongated adhesive members 36 such as those described above.

FIG. 14 shows the subject device installed in the window 42 of the surgical drape 40. The desired form of the skin closure device is as described above. With this construction the skin closure device can be installed in the window prior to surgery after being marked up or otherwise prepared and can be removed from the window 42 at the conclusion of surgery whereby the skin closure device will remain attached to the body of the person who had the surgery and the drape 40 will be removed. The subject skin closure can be installed in the drape using the various means described above including zipper means, snap fasteners, VELCRO, hook and loop fasteners and it can be made integral with the drape and removed by cutting it around the periphery of the window at the desired time. It can also be attached along one or more sides of the window 42, as desired, using the desired attaching means.

Thus there has been shown and described several embodiments of a skin closure device which is flexible and provides the surgeon with many different options and advantages. The subject skin closure device also minimizes one of the problems with known devices, namely, the problem of having the skin closure device expand and contract at a different rate than the skin to which is it attached. This is accomplished with the present device by making the area adjacent to the incision non adhesive at least during the surgery although it may be made adhesive by removing cover flaps therefrom at the conclusion of surgery when there is no longer the problem of producing a stressed condition between the skin and the skin closure device.
