Abstract
An exemplary embodiment provides a steering gear () for a surgical instrument () which has two motorised drives and is designed to spatially align a swash plate () via the adjustment angles of the two drives, which is designed to control the distal bending mechanism () of the surgical instrument (). The first drive has a first drive pinion () which can be driven by a first motor () via a first drive shaft () which defines a first drive axis (C) and which is connected to a first drive wheel rim () of a first drive wheel () in operative connection. The second drive has a second drive pinion (') which can be driven by a second motor (′) via a second drive shaft (′) which defines a second drive axis (C′) and is connected to a second drive wheel rim (′) of a second drive wheel (′) in operative connection. The first and the second drive wheel (′) are designed as double wheels (′), each of which has the corresponding drive wheel rim (′) and a deviation wheel rim (′), wherein between the two drive wheels (′) which have a common axis of rotation (A), the swash plate () is arranged, and the deviation wheel rims (′) are arranged facing each other on the axis of rotation (A). A surgical instrument () with such a steering gear () is also disclosed.
