  • Patent number: 9655636
    Abstract: A medical instrument with a handle arranged at the proximal end, with a shank arranged on the handle, and with a tool arranged at the distal end of the shank. The medical instrument can provide several functionalities, for example the rotation about the longitudinal axis of the medical instrument, the pivoting of the tool relative to the longitudinal axis of the medical instrument and/or the actuation of the tool, for example the opening or closing of scissors. Some of these functionalities are activated with the aid of a single common actuation element. By moving the actuation element between several switch positions, different functionalities are selected, and these are activated, e.g. by rotation of the actuation element.

  • Patent number: 9445792
    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.
