Device for the repeated piercing of an organic tissue, an application module and a method thereof

A method for repeated piercing of an organic tissue with a device having 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, said method comprises:

• displacement by way of the operating mechanism of the application tools relative to each other between an initial position and a penetration position repeatedly, in that the at least one application tool and one other application tool of the arrangement are moved relative to each other repeatedly;
• and
• countering an effect direction of an application force provided by the at least one application tool to an effect direction of the application force provided by the other application tool during the relative movement,
• 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, during piercing of the organic tissue, the respective distal end of each application element causes a pre-tensioning of the organic tissue such that the piercing of the organic tissue by the at least one application tool is supported by the other application tool, 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.

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 displaced relative to each other between an initial position and a penetration position repeatedly, in that the at least one application tool and one other application tool of the arrangement are configured to be move by the operating mechanism relative to each other repeatedly, and
• the at least one application tool is arranged to provide during the relative movement 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 with the device viewed in a direction perpendicular to the application force provided by the at least one application tool as well as by the other application tool, the at least one and the other application tool are arranged to cross each other at least in the penetration position, such that an angle between the at least one application tool and the other application tool is larger than 0° and less than 180°,
• 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, in operation as the at least one application tool pierces the organic tissue, a respective distal end of each application element is configured to cause a pre-tensioning of the organic tissue such that the organic tissue is supported by the other application tool, 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.
