Abstract
The invention relates to a medical instrument consisting of at least two instrument parts, which is provided with a coupling for releasably connecting the two instrument parts, wherein the coupling having a locking element which may be moved between a released and a locked position, as well as at least one magnet element which produces a magnetic restoring force which retains the locking element in the locked position.
Claims18
A medical instrument comprising:
- a first element extending along an axis and a second element, the first and second elements being axially, directly and releasably coupled to one another;
- a locking element displaceable between a released position and a locking position so that when the locking element is in the locking position the first and second elements are locked together by the locking element and so that when the locking element is in the released position the first and second elements are releasable from one another;
- and
- a magnet element coupled to at least one of the first element and the locking element, the magnet element being operative to produce a magnetic force to urge the locking element into the locking position.
