Zusammenfassung:The disclosure relates to a steering mechanism for a surgical instrument. The steering mechanism has two motorized drives and is designed to spatially align a swash plate over the control angle of the two drives, said swash plate being designed to control a distal bending mechanism of the surgical instrument. A first drive of the two drives has a first motor which drives a worm shaft that drives a worm wheel rim of a double gear consisting of a worm wheel rim and a bevel wheel rim), and a second drive of the two drives has a second motor which drives a worm shaft that drives a worm wheel rim of a double gear consisting of a worm wheel rim and a bevel wheel rim. The swash plate is arranged between the two bevel wheel rims, which face each other and lie on a common axis.
