Problems solved by technology

The disadvantage is therefore the complex construction and the inability of the contents of the cartridge to be mixed by means of a mixing system to be manipulated externally after the monomer liquid has been pumped in, since the feed-through of the mixing rod or mixing tube ( feed-through) permanent vacuum seal

Embodiment Construction

[0187] Figures 1 to 6 An exemplary embodiment of a first storage and mixing device of the present invention is shown. here, figure 1 A schematic cross-sectional view of a first exemplary storage and mixing device of the present invention is shown in an initial state. The storage and mixing device comprises a cartridge 1 with a cylindrical interior in which a plunger 2 is arranged to be linearly movable in the axial direction. On the front side of the cartridge 1 ( figure 1 and 3 to 5, at the top), the interior or cartridge 1 is closed by a cartridge head 3 similar to a cap or cap. The cartridge head 3 is sealed against the cartridge 1 by means of a circumferential seal. In the interior of the cartridge 1 , the bone cement powder 4 as the first matrix component 4 of PMMA bone cement is located between the plunger 2 and the cartridge head 3 .

[0188] The plunger 2 is in gas-tight contact with the inner wall of the interior of the cartridge 1 by means of a circumferential...

Abstract

The invention relates to a storage and mixing device for bone cement with a pressure pump, specifically to a storage and mixing device for two-component polymethyl methacrylate bone cements having a cartridge with a cylindrical interior. The invention further relates to a method of using the parental components of the storage and mixing device for bone cement with a pressure pump, specifically to a storage and mixing device for two-component polymethyl methacrylate bone cements.

Description

technical field [0001] The invention relates to a storage and mixing device for a two-component polymethylmethacrylate bone cement, said storage and mixing device having a cartridge with a cylindrical interior. [0002] The present invention also relates to a method of mixing a bone cement, in particular a matrix component of a two-component polymethylmethacrylate bone cement, using such a storage and mixing device. Background technique [0003] Polymethylmethacrylate (PMMA) bone cement dates back to the foundational work of Sir Charnley (Charnley, J.: Anchorage of the femoral head prosthesis of the femoral body). headprosthesis of the shaft of the femur). Bone and Joint Surgery (J. Bone Joint Surg.) 42(1960) 28-30). PMMA bone cement consists of liquid monomer components and powder components. The monomer component usually contains methyl methacrylate monomer and an activator (N,N-dimethyl-p-toluidine) dissolved therein. The powder component (also referred to as bone ceme...
