The invention relates to a surgical instrument comprising a tool which can pivot in an oscillating manner around a rotational axis and a drive shaft which is driven in a rotating manner and which pivots an oscillating lever back and forth which is rotationally fixed to the tool by means of an eccentric. The aim of the invention is to adapt the pivoting angle of each tool in a simple manner. The drive shaft comprises at least two adjacent eccentrics having different eccentricity and an oscillating lever which can pivot around the axis of rotation of the tool is associated with each eccentric and the tool is rotationally connected to only one of the oscillating levers. |
