Abstract: The invention relates to a device for retaining and moving a laparoscope during an operation, which comprises a securing unit for securing on a retaining arm, a receiving unit for retaining the laparoscope, as well as a main body. Furthermore, the device has a lever via which the receiving unit is secured to the main body. The main body is mounted on the securing unit in a rotatable manner about a first rotation axis via a first rotation unit. The lever is mounted on the main body in a rotatable manner about a second rotation axis via a second rotation unit. Furthermore, a first drive unit is provided, which, upon activation, drives the first and the second rotation unit in such a manner that the main body is rotated about the first rotation axis, and the lever is rotated about the second rotation axis by the same rotation angle in the opposite rotation direction.

Abstract: The invention relates to a device for suction of liquids and/or particles from body orifices, wherein the device comprises a suction channel (16) through which the liquid and/or particles can be aspirated and a vacuum pump (14) for generating an underpressure in the suction channel (16). The suction channel (16) is provided with an opening for supplying additional air for adjusting the underpressure, wherein the volume flow of this additional air is adjustable via an additional air adjustment unit (24). Further, the device (10) has a manually operable adjustment unit (26) for adjusting the additional air adjustment unit (24), wherein the adjustment of the adjustment unit (26) in each case by a same preset adjustment way effects in each case the same change in the underpressure.
