Abstract: A method is provided for cleaning at least one filter of a vacuum cleaner, wherein the vacuum cleaner comprises a suction inlet and a dirt collection container, which can be subjected to negative pressure by a suction unit via the at least one filter and a suction extraction line, and wherein for cleaning purposes the at least one filter can be acted upon by external air on the clean side via at least one external air valve, which moves from a closed valve position via an open valve position back into the closed valve position for cleaning the at least one filter. So that the at least one filter can be cleaned particularly effectively, the suction power of the suction unit can be increased before transfer of the external air valve to the open valve position and reduced again later. A vacuum cleaner for performing the method is also provided.

Abstract: The present invention discloses a securing device that is used to secure a fixation device to two bone portions to promote healing between the two bone portions. The bone portions commonly include a skull bone portion and a skull bone flap or implant, and the fixation device is commonly a cranial clamp. The securing device provides for securing the fixation device in a uniform, single movement as opposed to currently available products. The securing device has two handles pivotably connected, and a gripping means moveably associated with one handle. As the handles are activated, the gripping means travels proximally along the one handle and grips an elongated section of the fixation device and exerts a tensioning force along the shaft of the elongated section prior to the cutting means cutting the elongated shaft to secure the fixation device in place.
