Abstract

The present invention relates to a device for adhering to the skin of a patient, suitable to make a skin incision there through, as well as to the use of such a device for allowing an incision or excision wound to be made through the said device, and for subsequent closing the wound. In particular, the device is suitable for adhering to the skin at the location the incision or excision is to be made, where after the incision or excision is made through the device in the skin at the envisaged location. The device comprises one or more basic layers (1, 2) that do not abut one another at the location of the wound. In contrast, an open skin area (3) is defined by the basic layer(s), which area is covered by an adhesive surface of a covering sheet (4). Further, adhesive strips (13, 23) are provided that are suitable to be adhered to the skin at both sides of the incision, therewith closing the skin in a highly controlled manner, and enabling excision wounds to be conveniently closed as well
