Abstract
A handling device for a micro-invasive surgical instrument includes a gripping device to manually hold and guide the handling device, a shaft coupling to detachably mechanically couple the handling device with a proximal end of a shaft, a rod coupling that can slide inside the handling device for detachable mechanical coupling with a proximal end of a transmission rod that can be slid inside a shaft coupled with the shaft coupling, and an orientation device to rotate a proximal end of a transmission rod, which has been inserted into the handling device, into a predetermined orientation or into one of several predetermined orientations.
Claims10
A handling device for a micro-invasive surgical instrument, having:
- a gripping device for manual holding and guiding of the handling device;
- a shaft coupling for detachable mechanical coupling of the handling device with a proximal end of a shaft;
- a rod coupling that can be at least either slid or rotated in the handling device for detachable mechanical coupling with a proximal end of a transmission rod, which can either slide or rotate in a shaft that is coupled with the shaft coupling;
- an orientation device to rotate a proximal end of a transmission rod inserted in the handling device into a predetermined orientation or into one of several predetermined orientations.

- a rod coupling that can be at least either slid or rotated in the handling device for detachable mechanical coupling with a proximal end of a transmission rod, which can either slide or rotate in a shaft that is coupled with the shaft coupling;
- an orientation device to rotate a proximal end of a transmission rod inserted in the handling device into a predetermined orientation or into one of several predetermined orientations;
- wherein a distal end of the shaft is mechanically connected or connectable with a tool;
- and
- the transmission rod transmits at least either a force or a torque from the handling device to the distal end of the shaft,
- such that the transmission rod comprises on its proximal end a non-rotation-symmetrical shape that corresponds to the shape of the orientation device.
