MEDICAL INSTRUMENT

The invention relates to a medical instrument, comprising two instrument branches pivotally coupled to each other, each of the instrument branches having a proximal handling portion and a distal jaw portion, the distal jaw portions forming an instrument mouth which is movable, by a pivotal movement of the instrument branches, between a closed state, in which the jaw portions are moved inwardly toward each other, and an open state, in which the jaw portions are moved outwardly away from each other, wherein at least one of the instrument branches comprises a branch member and a jaw member, the branch member being elongated along a proximal/distal axis and having one of the proximal handling portions and a distal coupling portion, the jaw member forming one of the jaw portions and having a proximal complementary coupling portion, and wherein the coupling portion and the complementary coupling portion form a releasable connection to exchangeably attach the jaw member to the branch member. According to the invention the coupling portion is a wedge-shaped protrusion and the complementary coupling portion is a complementary wedge-shaped recess, or vice versa, wherein the wedge-shaped protrusion comprises two wedge surfaces opposing each other along a medial/lateral axis, wherein the opposing wedge surfaces are inclined in proximal direction toward each other by a first angle of inclination, and wherein the opposing wedge surfaces are inclined inwardly toward each other by a second angle of inclination.
