Embodiment Construction

[0093] For simplicity, identical or similar components are identified with the same reference numerals in the figures. The cut surfaces are shown by hatching.

[0094] figure 1 A schematic cross-sectional view of a device according to the invention is shown. The device has a first container 1 with a cylindrical inner space which is filled or can be filled with a first component of PMMA bone cement. The first container 1 contained a slurry-like mass containing methyl methacrylate monomer as a first component. The first container 1 has on its side a wall 2 of a cylindrical plastic body for its boundary. The first container 1 is on its back (on figure 1 on the bottom in ) has a cylindrical dispensing plunger 4 for its border. The first container 1 is on its front side (in figure 1 on top of ) has a volume compensating element 6 in the form of a cylindrical plunger for its boundary. The dispensing plunger 4 as well as the volume compensating plunger 6 are arranged in the wa...

Abstract

A device stores, mixes, and applies polymethylmethacrylate bone cement. The device comprises a first container for a first pasty component of the bone cement, a dispensing plunger arranged in the first container such that it can be shifted and serves for pressing the content of the first container out of a dispensing opening, a mixing facility for mixing the content of the first container, whereby the mixing facility is arranged in the first container and the mixing facility can be moved in the first container from outside for mixing, and at least one second container for at least one second component of the bone cement is arranged in or on said first container. The second container can be opened, such that the contents of the first container and second container can be mixed with each other in the first container, whereby at least a boundary surface of the first container is formed by a mobile volume compensation element.

Description

technical field [0001] The present invention relates to a device for storing, mixing and applying polymethyl methacrylate bone cement and a method for producing polymethyl methacrylate bone cement using said device. [0002] The subject of the invention is therefore a device for storing and mixing a polymethylmethacrylate bone cement consisting of a paste-like component A and a separate powder-like or paste-like component B during storage and before mixing, and A method for mixing component A and component B. Background technique [0003] Polymethylmethacrylate bone cement (PMMA bone cement) has been used medically for decades for the permanent mechanical fixation of total joint endoprostheses. These are based on powder-liquid systems, whereby it is customary to use methyl methacrylate as monomer. Recently, polymethylmethacrylate bone cements based on the use of cement pastes have also been proposed (DE 10 2007 050 762B3, DE 10 2008 030 312A1, DE 10 2007 052 ​​116A1). The...
