The invention relates to a device (1) for creating an intercostal transcutaneous access to an, in particular endoscopic, operating field comprising a base body (3), which surrounds an incision (2) frame-shaped and with at least two webs (4) mounted on the base body (3), which can be introduced into an intercostal space (10), by which two ribs (5) arranged next to each other can be moved apart. To create a device (1) for creating an intercostal transcutaneous access to an, in particular endoscopic, operating field which allows individual pressing apart of the ribs (5), it is proposed according to the invention that the at least two webs (4) are mounted adjustable relative to each other on the base body (3).
