    Abstract: A tool for a dismantlable medical instrument includes a first component, which surrounds a cavity for receiving a distal end of a shank, and a second component with a catch, which protrudes into the cavity surrounded by the first component to form a bayonet connection with a distal end of a shank protruding into the cavity, by engagement of the catch in a slit or a groove at the distal end of the shank. The first component has a recess into which the second component is fitted.

    Abstract: A medical instrument having a shaft, at the proximal end of which a handle is arranged, wherein the shaft is rotatable about its longitudinal axis and can be secured in various positions of rotation relative to the handle via a licking mechanism. In order for a medical instrument with a shaft rotatable about its longitudinal axis to be designed in such a way that, while being easy to handle, it permits a large number of secure and positionally precise rotations of the shaft with respect to the handle, the licking mechanism is designed as a latching mechanism which has a perforated disk with recesses and latching elements, wherein the latching elements and/or the perforated disk are spring-loaded relative to each other, and at least one of the latching elements engages in a corresponding recess of the perforated disk in order to fix the shaft.

    Abstract: A medical instrument according to the invention has an elongate shank, and a tool which is arranged on a distal end portion of the shank and which comprises two tool elements interacting with each other, of which at least one tool element is movable by a longitudinally displaceable first transmission element. A distal end portion of the first transmission element has a surface inclined with respect to a direction of displacement, and the distal end portion of the shank, or an element connected non-displaceably thereto, has a mating surface which is inclined with respect to the direction of displacement and which, with the inclined surface, forms an interspace dependent on a displacement of the distal end portion of the first transmission element.
