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. The inner bearing element has a second pair of outer openings and a second pair of inner openings. A thread-like tensioning element is provided which is threaded through the openings of the outer and inner bearing elements in a displaceable manner, such that, when tensioned, the tensioning element draws the inner bearing element and the outer bearing element together.

Abstract: To avoid a maximum displacing force being exceeded in the case of a device for pushing together a thread loop which is formed by a slip knot at the distal free end of the thread which can be displaced along the thread, with a displacing element which can be displaced on the thread in the direction of the loop, it is proposed that the displacing element or the proximal portion of the thread disposed at the end of the displacing element remote from the loop has connected to it a gripping element which releases the connection between itself and the displacing element or the proximal portion of the thread when a specific holding force is exceeded.

Abstract: In order to provide an implant for fixing adjacent bone plates, in particular cranial bone plates, which has an inner abutment element by means of which a separation gap between the bone plates can be overlapped at a bone plate inner side and has an outer abutment element for overlapping the separation gap at a bone plate outer side lying opposite the bone plate inner side and which is easy for a surgeon to use and by means of which the bone plates may be securely fixed, it is proposed that at least one tension band is guided displaceably through the outer abutment element, by means of which, when a tensile stress is exerted, the inner abutment element and the outer abutment element are mutually braceable, and that the at least one tension band is fixable on the outer abutment element.

Abstract: In an implant for fixing neighbouring bone plates of the cranial bone comprising an inner bearing element which covers a spacing gap between the bone plates, an outer bearing element which covers the spacing gap and a connecting device which penetrates the spacing gap and which, when said bearing elements approach one another, connects the bearing elements together by means of a latching or a clamping connection in such a manner that they are no longer able to be moved apart, it is proposed that the two bearing elements be additionally connected by a thread-like tensioning element which is passed through the outer bearing element in displaceable manner and, when tensioned, moves the inner bearing element towards the outer bearing element in order to simplify the process of applying the implant and to ensure a secure connection of the bearing elements.

Abstract: In order to simplify the structure and production in the case of a surgical clip with two clamping arms, which may be swivelled relative to one another around a rotational axis and in one clamping position have a clamping region where they essentially abut one another, said clamping arms respectively having a free end and an end provided with a bearing, wherein a joint shaft defining the rotational axis is disposed in the two bearings, and with a tension element assigned to the two clamping arms and holding these under prestress in the clamping position, it is proposed that the shaft is formed by the tension element.

Abstract: The invention relates to a head clamping device (1) comprising a frame composed of two elements (2,3) exhibiting each first ends (7) flexibly connected to each other and second ends (5) with spikes (13,19) for fixing the head. The aim of the invention is to increase the mechanical stability of such a device. For that purpose, the frame elements (2,3) are mounted in such a way that they can rotate relatively to each other around a common rotation axis (4).

Abstract: In order to make an improved securing of the plastic sheath on the holder possible in a surgical tubular-shafted instrument with a shaft, at the distal end of which at least one tool is arranged on a holder which, for its part, is secured in position on the shaft, and with a plastic sheath partially covering the holder, it is suggested that the plastic sheath engage at its edge beneath projections on the holder.

Abstract: In a surgical applicator for U-shaped clips comprising a handle, a tubular shaft adjoining the handle, a forceps-type applicator tool at the free end of the tubular shaft, a closing mechanism for the applicator tool arranged in the tubular shaft and actuatable from the handle, an advancing mechanism for the clips arranged in the tubular shaft and also actuatable from the handle, two separate actuating elements on the handle, each being movable between a rest position and a work position, one of the actuating elements being associated with the closing mechanism and the other with the advancing mechanism, in order to improve the safety measures and the actuating aids, it is proposed that a locking member be mounted on one of the actuating elements and enter into operative connection with the other actuating element, thereby to prevent each of the two actuating elements from moving so long as the respective other actuating element is not in its rest position.

Abstract: To facilitate the production of a surgical vascular clip having two arms with clamping jaws, the arms being resiliently pressable against each other and meeting at an end section of the clip, and also having a tensioning section adjoining the end section in the direction towards the clamping jaws and being surrounded by a ring displaceable in the longitudinal direction of the tensioning section, it is proposed that the arms with the clamping jaws, the tensioning section and the end section be designed as a one-piece component.

Abstract: A surgical instrument including a shank, at least one tool mounted for swivel movement at the end of the shank, a swivel element mounted for swivel movement about an axis of rotation for swivelling the tool between an open position and a closed position, and an actuating member actuatable from an end of the shank located opposite the tool for swivelling the swivel element about the axis of rotation. The high closing forces required for plastic deformation of objects can also be achieved without excessive forces being transmitted to the drive mechanisms. The actuating member is an arm which is articulatedly connected at a first articulation point to the swivel element, and that in the open position of the tool, the arm be at an incline to an axis of the swivel element extending perpendicularly to the axis of rotation through the first articulation point and in the closed position of the tool, be essentially perpendicular to the axis of the swivel element.

Abstract: To enable easier manufacturability of the clamping ring for a surgical clip comprising two arms which are elastically pivotable towards each other and each have one clamping jaw, an end section in which the arms meet, and located therebetween a tensioning section on which the clamping ring surrounding the arms is displaceable in the longitudinal direction, with a part connected to the clamping ring engaging between the arms, it is proposed that the clamping ring carry diametrically opposed projections integrally formed on the clamping ring and protruding inwardly into the area surrounded by the clamping ring.

Abstract: A tubular-handled surgical instrument has two mutually articulated grip shanks. A tube is secured on one of the shanks, with a tool fitted at its end. A rod-like actuator for the tool is fitted to move longitudinally in the tube and articulated on the other shank via a cylindrical or spherical end. A releasable connection is provided between the tube and the actuator on the one hand and between the two shanks on the other. The tube is insertable into a tubular recess in one shank and axially securable therein by at least one radially movable spherical locking member making a friction fit with the tube in one end position. The radial movement of the locking member is limited by a stop bearing on the outside of the locking member formed by a sleeve axially movable on the tubular recess. The sleeve is movable in relation to the locking member in such a way that the locking member can be moved radially outwards to differing extents.
