Abstract: An instrument is provided for applying light, particularly laser light, to the human or animal body. A tubular shaft is provided into which a flexible light waveguide may be inserted, where a light-emitting end of the waveguide comes to rest at a distal end portion of the tubular shaft. The distal end portion of the tubular shaft is pivotally connected with the remaining portion of the tubular shaft, so that the distal end portion may be pivoted away from the longitudinal axis of the tubular shaft. Manipulating devices are provided at the proximal end of the tubular shaft for pivoting the distal end portion. The manipulating devices include at least one movable operating element, which is directly connected to the distal end portion by means of an actuator element.
