Abstract: An apparatus for video endoscopy, in particular for industrial video endoscopy, has a device part which has a housing and an electronics component arrangement which is arranged in the housing. The electronics component arrangement is arranged within a sealed-off region in the housing. A heat sink is arranged in the housing, the said heat sink being thermally coupled to the electronics component arrangement in order to absorb heat from the electronics component arrangement. A fan for generating an air flow of ambient air is arranged in the housing, the said air flow flowing out of the housing along the heat sink in order to discharge the heat from the heat sink, wherein the air flow does not come into contact with the electronics component arrangement.

Abstract: The invention relates to a power unit which is receivable in or at a medical handheld medical device in a disengageable manner, wherein the power unit includes at least a voltage source, a motor and/or a circuit board, wherein the power unit includes an arrangement for identifying which is configured to identify at least one feature of the medical handheld device and to emit a signal caused by the identified feature or based on the identified feature. The invention furthermore relates to a medical handheld device, comprising at least one power unit according to one of the preceding claims and/or at least one feature which is provided to be identified through the identification arrangement. The invention furthermore relates to an arrangement for identifying a medical handheld device that is connected with the power unit according to the invention.

Abstract: A light system for medical photodynamic applications comprises an incoherent light source emitting a light with a power and a light guide which has a distal end and an entrance interface. The entrance interface and the light source have a position relative to one another and are able to be positioned relative to one another. The light system further comprises a luminous power meter for measuring a luminous power emitted at the distal end of the light guide, a motorized positioning unit for positioning the entrance interface and the light source relative to one another, and a control unit which controls the positioning unit as a function of the luminous power measured by the luminous power meter.
