Abstract: An endoscopic instrument having an instrument body configured in a long, slim and flexible manner. The instrument may be completely or partly wound in one or more windings that allows the instrument to be packed in a space-saving and easy-to-handle manner. To keep the instrument body in this position, a holding device is provided that is arranged on the instrument body and is preferably undetachably held there. The holding device has a gripper rotatably supported around the instrument body. The instrument body has a latch to hold and fasten the windings.

Abstract: The invention relates to an electrosurgical instrument, especially for argon plasma coagulation, with a handle (10), an outer shaft (12) that surrounds an electrode and/or an inner shaft (11, 111) and is held in the handle (10), and an actuation mechanism (13) on the handle (10) to move the outer shaft (12) in the axial direction relative to the electrode/to the inner shaft (11, 111). The invention is characterized in that the inner shaft and/or the electrode (11, 111) are mechanically connected with one another in a distal end area (65) of the outer shaft (12) in such a way that the inner shaft and/or the electrode (11, 111) can be bent by moving the outer shaft (12) relative to the inner shaft and/or to the electrode (11, 111).

Abstract: A method increases the spatial resolution of a source image based on an auxiliary, co-registered image of a higher spatial resolution. Each of the source and auxiliary images includes a plurality of pixels with corresponding spectral intensities and the method includes reducing, identifying, deriving, subdividing and modifying steps. Multiple auxiliary images can be used with the method. In the reducing step, a spatial resolution of the auxiliary image is reduced to a common resolution with the source image. Then in the identifying step, corresponding groups of pixels at the common resolution in the source and auxiliary images are identified. Then in the deriving step, a mapping function is derived which relates the rate of change of intensity of each group in the auxiliary image and the corresponding rate of change of intensity in the corresponding group in the source image to the intensity vector. This map can be conditioned on any number of auxiliary image planes.
