Abstract: The invention relates to an irradiation-cooling combination for application in photodynamic therapy having an irradiation element (120), a cooling element (130) permeable by the emitted radiation in an irradiation pass-through direction, wherein said cooling element is designed for attachment between the irradiation element (120) and a treatment surface (160) of a patient. The cooling element (130) has an optical pass-through surface that can be cooled as an attachment to the treatment surface (160). Additional components of the invention are a first fastening device (150) for defined positioning of the irradiation-cooling combination opposite the treatment surface (160), a second fastening device (140) for attaching the irradiation element (120) on the cooling element (130), a control unit (110) and a power supply (100). The invention provides effective pain management during photodynamic therapy in connection with a mobile treatment system and larger treatment areas by means of a uniform radiation field.

Abstract: A setting tool for screwing a threaded rod into a receiving material includes a work driver formed by a sleeve-like member. A retainer part is secured within one end of the sleeve-like member for holding the threaded rod while it is inserted. The end of the threaded rod located in the retainer part bears against a piston positioned within the sleeve-like member. A hydraulic medium holds the piston against the end of the threaded rod so that the rod is held in the work driver. After a threaded rod has been set, the rod can be removed from the retainer part by relieving the pressure of the hydraulic medium acting on the piston. The pressure is built-up as the threaded rod is screwed into the receiving material. The pressure is released by opening a valve connected to the space in the sleeve-like member containing the piston and hydraulic medium.
