Abstract: A slotted nozzle for discharging a liquid adhesive to a narrow edge of a substrate includes a nozzle body, a nozzle slot formed in the nozzle body, a passage in the nozzle body for supplying the adhesive to the nozzle slot, and a slot-shaped outlet opening of the nozzle slot. The nozzle body is configured in the region of averted ends of the nozzle slot that are based on the longitudinal extent of the nozzle slot in such a manner that an increased outlet of the adhesive through the outlet opening takes place in the region of the averted ends of the nozzle slot.

Abstract: The invention relates to an intervertebral disk implant having two implant plates contacting prepared vertebral body surfaces in the implanted state and an implant core which can be introduced between the implant plates. The invention further relates to a method for the manufacture of an intervertebral disk implant.

Abstract: Systems, devices, and processes for aspirating, fragmenting and extracting removable material from hollow bodies. A guide wire (11) is inserted into the hollow body (1) via an opening. Material is removed by means of a reducing catheter (3) having a working head (6) with stator (8) and rotor (9) that is connected to a feed screw (10). The stator (8) has a lateral inlet opening (8a) which is formed as two circular holes arranged in axial succession. Material forced into the inlet openings (8a) is sheared and/or fragmented. A flexible sleeve (7) serves to discharge the ablated material. Prior to this, a sheathing catheter (4) is inserted into the hollow body (1) until in front of the material to be removed. The cross-section of the hollow body (1) is occluded by the sheathing catheter (4), preventing detached fragments from being accidentally washed away.

Abstract: The invention relates to a targeting aid for the spatial fixing of a target device relative to spinal vertebrae of a patient, comprising a clamping tool which is formed as a pair of forceps and which has at least two clamping jaws with which the clamping tool can be fixedly clamped to the spinal vertebrae while bridging at least two adjacent spinal vertebrae, and comprising at least one target base which is fixedly connected to the clamping tool and which is formed for coupling to a separate target device.

Abstract: The invention shows a filling transfer apparatus for bone cement with a cylindrical, upwardly open mixing container (1) and a filling transfer piston (2) which can be inserted therein, which is removably connected to the sleeve (4) of a cement injector (3) and which has an opening (5) through which the mixed bone cement (6) can be transferred into the sleeve (4) through a pressing down of the filling transfer piston (2). In this an ejection piston (7) is inserted in the sleeve (4) and has an aperture (8) in the region of the opening (5) for the through-flowing cement which can be closed by a plug (9) after the removal of the cement injector (3).

Abstract: With the invention blocking systems for the medullary canal (1) of a tubular bone (2) are shown which have a blocking element (5) in order to hold bone cement (3) back from cemented prosthesis shafts (4). Because a deformable plug (6) which can be decomposed in the body is placed on between the blocking element (15) and the shaft end (7), which prevents an advance of liquid bone cement (3) in the capacity of a fill-in and which permits a penetration of the end (7) of the prosthesis shaft (4), a cement socket without a base arises which permits settling movements of the shaft in the hardened bone cement.

Abstract: A transport and processing apparatus for a two-component material, in particular for bone cement, has a liquid component (1) and a powder component (2) which are separated by a membrane (3) and each occupy a transport chamber (4, 5) in a closeable container (6, 7) which has an expulsion piston (8) at one end and an opening (9) for the expulsion of mixed two-component material at the opposite end. The transport chamber (4) for the liquid component has a ring shape and a central aperture (34) for expelling the mixed two-component material through the aperture (34). The membrane is destroyed by a relative movement between the transport chamber for the liquid component (1) and a solid body (12, 17) enclosed in the container in order to effect a flow of the liquid component (1) into the transport chamber (5) for the powder component (2) and to enable the mixing with a mixing piston (11).

Abstract: The invention shows a filling apparatus for the introduction of bone cement into the intramedullary cavity of a bone, preferably into the cavity of a femur bone. The apparatus has a filling cannula, at the end of which a rubber sleeve in the form of a sheet metal bell is fastened which projects with its movable part radially beyond the diameter of the filling cannula and axially beyond a lowermost outlet aperture of the filling cannula. Because the sleeve is executed in the lower expandable part with a thickness 1 mm<s<2 mm and is fastened above an uppermost outlet aperture of the filling cannula at a distance 3 mm<1<50 mm and projects with its lower edge beyond a lowermost deflection edge 11a of a lower outlet aperture by a distance 5 mm<a<50 mm, its cross-section adapts to the cavity wall when being introduced without getting caught up and seals it during the expulsion of the bone cement.
