  • Patent number: 10828063
    Abstract: A medical instrument includes a proximal handle (3), for controlling a distal tool, including two grip pieces (4, 5) pivotable relative to one another, subjected to spring force and coupled in movement via a path guide with a path component (7). The path component includes a guide path (11), and a guide body (14) on a guide component (8). The guide body engages into the guide path. The components (7, 8) are arranged on one of the grip pieces and are subjected to a spring force, transversely to a pivoting plane of the grip pieces. One of the components (8) is pivotably arranged on a grip piece. Functionally independent of the guide body (14) and guide path (11), a latching body (12) is received by a latching receiver (16) on the components (7, 8) for a latching function, blocking pivoting movement of the grip pieces.

  • Patent number: 10548622
    Abstract: An instrument, a medical-endoscopic instrument or technoscope, includes a shank (2) and an instrument head (10), which is arranged at a distal shank end of the shank (2) and is bendable relative thereto via a joint. The instrument head (10) includes a tool with two jaw parts (20, 22) which are pivotable relative to one another and are coupled in each case to two pull cables (70, 72, 76), for the control of the jaw parts (20, 22). These pull cables (70, 72, 76), in the region of the joint, are guided around two deflecting rollers (78, 80, 82, 84, 86, 88, 90, 92). Deflecting roller pairs are arranged on both sides of a middle axis (A) of the instrument. Deflecting rollers (82, 84, 90, 92) of a first deflecting roller pair have a smaller diameter than deflecting rollers (78, 80, 86, 88) of a second deflecting roller pair.

  • Patent number: 10080553
    Abstract: A medical instrument includes instrument parts which can be releasably connected to one another. One part includes a hollow-cone-shaped receiving space and another part includes a cone-shaped coupling section which can be inserted into the receiving space to connect the parts. The coupling section includes a locking receiver for a locking element of the receiving space and which can be brought into and out of engagement with the locking receiver. A securing element moves between a position holding the locking element in a locking position, and a position releasing the locking element. An actuation element projects into the receiving space of the first instrument part, engages into the locking receiver in the locking position of the locking element and is movable in the direction of its middle axis. The middle axis of the actuation element is aligned in the proximal direction obliquely to a middle axis of the receiving space.
