Abstract
A coupling mechanism for mechanically connecting a first structural part and a second structural part of a medical instrument includes a first component and a second component, which are designed to be connected to each other by a bayonet connection that permits a rotation of the second component relative to the first component about a rotation axis, and a detent mechanism for alternately locking the second component in several alternative and mutually different predetermined angle positions relative to the first component.
Claims18
A coupling mechanism for mechanically connecting a first structural part and a second structural part of a medical instrument, with:
- a first component;
- a second component, wherein the first component and the second component are designed to be connected to each other by a bayonet connection that permits a rotation of the second component relative to the first component about a rotation axis in the connected state;
- a detent mechanism for alternately locking the second component in a first predetermined angle position or in a second predetermined angle position relative to the first component.
A medical instrument with:
- A shaft;
- a work mechanism for working on part of a human or animal body;
- a coupling mechanism with several predetermined configurations, for mechanically connecting the work mechanism to the shaft;
- wherein a first configuration of the coupling mechanism permits a fitting together and a non-destructive separation of work mechanism and shaft,
- wherein, in a second configuration of the coupling mechanism, the work mechanism is mechanically connected to the shaft in such a way that the work mechanism is movable along the shaft between a proximal position and a distal position.
