1. A device for the repeated piercing of an organic tissue with:
a penetration device which has an operating mechanism and an arrangement of application tools each of which is connected to the operating mechanism and has a distal tool end which is formed for at least one application tool with a penetration element,
the operating mechanism is configured to cause the application tools to displace relative to each other between an initial position and a penetration position, in that the at least one application tool and one other application tool of the arrangement are configured to be moved by the operating mechanism relative to each other, and
in which, as the at least one application tool and one other application tool of the arrangement move relative to each other, the at least one application tool is arranged to provide an effect direction of an application force that is counter to an effect direction of the application force provided by the other application tool, and
a mechanical actuation device which is connected to the operating mechanism and which is suitable for repeatedly effecting the relative displacement of the at least one application tool between the initial position and the penetration position with an operating frequency,
wherein the application tool and the other application tool each are formed with a comb component on which several adjacent application elements are arranged transverse to a longitudinal extension of the device such that, in operation, all of the several adjacent application elements make contact with the organic tissue at the same time,
wherein, a respective distal end of each application element is configured to cause a pre-tensioning of the organic tissue such that the other application tool supports the organic tissue as the at least one application tool pierces the organic tissue, and
wherein the penetration device is arranged in a housing, wherein the application elements of the application tools extend at least partly through a slit opening which is formed in the housing such that, in operation, organic tissue is removed from the application elements by an edge of the slit opening when moving the application tools from the penetration position to the initial position.
