Abstract: In order to ensure in any case, in the case of scissors for medical purposes comprising two scissor parts which are pivotally mounted on one another at a joint and each comprise a scissor blade, that the scissor blades of the scissor parts abut on one another under tension during the closure movement, it is suggested that the two scissor parts or parts securely connected to them have biasing elements, that the biasing elements of the two scissor parts abut on one another during their movement relative to one another when the scissor parts are pivoted and that the biasing elements be shaped such that the two scissor parts pass during closure from a rest position, in which the two scissor blades are not or only slightly biased against one another in the direction of their pivot axis, into a biasing position, in which the two scissor blades are brought closer to one another in the direction of their pivot axis and are thereby biased against one another.

Abstract: With an insertion catheter for inserting a vascular prosthesis into a vessel, with an elongate, substantially tubular catheter cover having a proximal and a distal end, with an outlet for the vascular prosthesis provided at the distal end, in order to make insertion of the vascular prosthesis into the vessel particularly safe and simple, in particular, to provide the vascular prosthesis with protection against twisting, it is proposed that the outlet have a cross-sectional shape differing from a circular shape, and that the cross-sectional area defined by the outlet area be smaller than the cross-sectional area of the vascular prosthesis inserted in the vessel in the opened, unexpanded state.

Abstract: An implant is provided for fixing neighbouring bone plates of the cranial bone in a simple and reliable manner. The implant comprises an outer bearing element for covering a spacing gap between the bone plates, which sits on outer surfaces of the bone plates. The outer bearing element has a first pair of outer openings and a first pair of inner openings. An inner bearing element is provided for covering the spacing gap between the bone plates, which sits on inner surfaces of the bone plates.

Abstract: A surgical, tubular-shafted instrument comprises a shaft, an operating rod mounted for displacement in the shaft, a handle part for actuating the operating rod and a connector that detachably connects the handle part to the shaft. The shaft is secured in an axial direction in an inner sleeve of the handle by a locking member that is displaceable radially in the inner sleeve and dips into a recess of the shaft. The radial outward movement of the locking member is limited by a stop element that is displaced into a position releasing the radial outward movement of the locking member. A holding element fixes the stop element in a release position and can be acted upon by the shaft to release the stop element due to displacement of the shaft in the inner sleeve. The holding element is guided for displacement in the handle part outside the inner sleeve.
