Abstract: A device for clamping off organic tissue has a tissue clamp with clamping bars in holders. A proximal clamping bar can be displaced in a guide groove of an application crosspiece by a tappet, while the distal clamping bar maintains its position until the tissue has been clamped off. The clamping bars have guide pin, or the distal clamping bar has a fixation shoulder. The pins or shoulder fit into crosswise grooves in the application crosspiece, and thus the clamping bars can be inserted into them vertically. The proximal clamping bar has a holder pin on its base that engages into a holder bore of the distal clamping bar. This produces a force-fit and shape-fit connection with this bore, while simultaneously clamping off the organic tissue. The guide pins shear off if the force required to clamp off the organic tissue is exceeded.

Abstract: Device for clamping organic tissue, in particular blood vessels in minimal invasive surgery, with an application base for holding two clamping bars of absorbing material which, in their final position, are connectable to become a tissue clamp. The tissue clamp can be separated from the latter by means of an inner pusher. The application base (2; 23) perpendicular to its longitudinal guide slot is equipped with two clamping bars and these can be merged to a tissue clamp. The application bar and clamping bars have guides, holders and fixatives which serve to precisely align the elements of the device and their unclamping.

Abstract: Medical instrument for injecting liquids into a hollow organ and/or drawing off liquids from a hollow organ, in particular a bile duct. Clamping apparatus are associated with the hollow needle of the instrument, this instrument being constructed as a tubular shaft, and the tissue of the hollow organ can be securely enclosed by these clamping apparatus between an entrance opening in the hollow organ and an outlet opening of the hollow needle in such a way that no liquid can escape between the tissue and the hollow needle.

Abstract: A medical instrument for placement of a knot, in particular, for operating within closed spaces. With the use of such instrument, the thread can be held, guided and/or manipulated at least on one side of the knot and adjacent thereto by an instrument head in such a way that the knot can be pushed into the vicinity of a target point and placed exactly in the target point by spreading at least one free end of the thread.
