drive unit for an endoscope

摘要

The drive has a flexible endoscope (2) which can move in an axial direction (A). The drive (1) has two carrier elements (3, 4), which are moveably ascertainable relative to each other and perpendicular to the axial direction (A) of the endoscope (2) in an adjustment direction (s) and in a desired position. The two carrier elements have a drive roll whose axle (9) is arranged perpendicularly to the axial direction (A) of the endoscope (2) and perpendicular to the adjustment direction (s). The drive role is a friction drive and propelled by a steering wheel or an adjustable electric drive (10). The electric drive (10) has a pedal (11) connected to its operation stroke and or operation direction and affected by the rotating speed and or direction of rotation of the drive role. The two carrier elements (3, 4) are movable and adjustable relative to each other by means of a screw thread element (14). The screw thread element (14) has an unlocking position in which the two carrier elements (3, 4) are removable from each other without manipulation of the screw thread element (14).
