  • 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.

  • Publication number: 20180263656
    Abstract: The medical instrument comprises a proximal handle (3) for controlling a distal tool. The handle (3) comprises two grip pieces (4, 5) which are arranged in a pivotably movable manner relative to one another, are subjected to spring force and are coupled in movement to one another via a path guide (11, 14), wherein the path guide (11, 14) comprises a path component (7) which comprises a guide path (11), and a guide body (14) on a guide component (8), said guide body engaging into the guide path (11). The components (7, 8) are arranged on one of the grip pieces (4, 5) and are subjected to spring force to one another transversely to a pivoting plane of the grip pieces (4, 5). One of the components (8) is pivotably arranged on a grip piece (4, 5). At least one latching position, in which the pivoting movement of the grip pieces (4, 5) is blocked in one direction, is formed between the components (7, 8).

  • Publication number: 20180256012
    Abstract: A medical-endoscopic shank instrument includes a hollow shank (2), a distal side housing (8) in the hollow shank, an electronic picture sensor (14) and/or a light located in the housing. The housing is linearly movable to move the picture sensor and/or the light from within an inner lumen (22) of the hollow shank to outside the inner lumen. The housing is displaceable through an opening (20) formed on a peripheral wall of the hollow shank. An inner-lying outer side (26), opposite and away from the opening, is formed on a peripheral wall of the hollow shank and is supported on an elongate carrier (32) which is guided in the hollow shank. The elongate carrier (32) is configured elastically resiliently transverse to longitudinal extensions thereof and extends essentially over a whole length of the hollow shank and is fixed in a region of the proximal end/proximally of the hollow shank.

  • Publication number: 20170143189
    Abstract: A shank instrument, particularly a medical-endoscopic shank instrument includes a hollow shank which between two rigid parts includes a part which is bendable transversely to a hollow shank longitudinal extension. The bendable part is fixedly connected to at least one of the rigid parts, in a manner such that two projections which are formed on a peripheral wall of one of the parts connected to one another, are arranged lying opposite one another on a peripheral wall and project in a direction of a longitudinal axis of the part, positively engage into two recesses which are formed lying opposite one another on a peripheral wall of the other part and which completely break through the peripheral wall. At the outer periphery, the parts of the hollow shank which are positively connected to one another, in the region of the positive connection are surrounded by a component.

  • Patent number: 8327518
    Abstract: With a method for manufacturing a bendable tube, which is preferably envisaged for an endoscopic instrument, first a tube is separated into several tube sections in a manner such that adjacent tube sections engage into one another with a positive fit in the axis direction of the tube. After the separation of the tube into several tube sections, one envisages peripherally arranging means for providing a positive fit transversely to the axis direction of the tube, on the regions of the tube sections, which are situated in engagement with one another.
