摘要:
System of implant components containing active agents, wherein each component is intended to function as an additive for an implant material produced with a powdery or finely granulated starting material and/or active agents and additives.Each component is powdery or finely granulated and includes at least one powdery or finely granulated active agent or additive having a higher dosage than the desired concentration for the application. The components themselves are made of a powdery or finely granulated starting material for the implant material, as well as of the active agent or additive. The active agents can be chemotherapeutical agents, such as antibiotics, whereas the additives can be x-ray contrast materials and/or or additives that alter the physical properties of the starting material, such as its elasticity or viscosity.

Blister packaging unit (10) for at least two components packed in separate individual packages, at least one of which has a pulverulent or granular consistency, which are to be prepared before use with the further packaged component(s) in a mixer or applicator to form a ready-to-use mixture. The individual packages of the components are inserted in correspondingly pre-shaped receptacles (32; 34) in the blister (30) of a suitable film or other material and this blister is closed on the side of the open mouth of the receptacles by a cover (36) of cardboard, plastic, metal or some other suitable material which may be torn off or opened in some other manner.The component(s) having the pulverulent or granular consistency is/are packaged in a respective individual blister pack (12; 14; 16) shaped at least approximately complementarily to the associated receptacle (32) in the blister packaging unit, the blister of which has the shape of an elongate trough element (12) of plastic material tapered at at least one end in the manner of a spout, which trough element(s) comprises a separate tear-off cover (16) of cardboard, plastic, metal or some other suitable material which may be torn off or opened in some other manner.
摘要:
A preparation and application device for implant materials consisting of at least one powder or granulate component and one liquid component, which are to be prepared immediately before use, is disclosed. The device comprises a first container which holds the powder or granulate component in a sterile, closed-off manner; and a second container which holds the liquid component in a sterile, closed-off manner and which can be connected to the first container. A mixing shaft which is hollow and located on a mixing mechanism is guided out of the first container is hollow and joins a hand pump for producing negative pressure at its external end. A measuring device which indicates the negative pressure can be connected to the first container and the housing of the hand pump is configured in such a way that it is suitable for use as a handle for moving the mixing shaft.
摘要:
The invention relates to a preparation and application device for materials which are to be prepared as a paste-like, flowable mass from at least one powder or granulate component and one liquid component, especially bone cement, with an elongated mixing cylinder for receiving the components to be mixed, comprising in one end region a sealable through-opening that can optionally be provided with a discharge unit for the paste-like material to be prepared, and a piston which can be inserted into the other, opposite, open end. The piston is displaceable in the cylinder and seals against the inner wall of the cylinder. The piston is penetrated by an elongated mixing shaft sealed against the piston, and a mixing mechanism is disposed at the cylinder inside-end of the mixing shaft and a handle disposed at the cylinder outside-end of the mixing shaft. The open end of the cylinder located opposite the through-opening and receiving the piston is additionally provided with a removable sealing cap that can be secured on and removed from the cylinder or piston and has a through-opening for the mixing shaft. The piston on the side of the sealing cap has a vacuum fitting adapted for connection to a vacuum source, which can produce a vacuum in the interior of the cylinder through a passageway provided in the piston. The sealing cap includes a through-opening through which the vacuum line that is connected to the vacuum source can be connected to the vacuum fitting in the piston.
摘要:
The powdery component of the implant material consists essentially of a mixture of hydroxyl apatite powder and calcium sulfate powder, wherein the hydroxyl apatite powder consists of synthetically prepared, precipitated crystalline nanoparticles of high purity, which have a crystal size of 10-20 nm width and 50-60 nm length. The specific absorbing BET surface area of the nanocrystals is preferably 100-150 m2/g.

The invention relates to a bone cement composed of a hydrophilic component and a hydrophobic component, wherein biodegradable material is deposited in pores of the bone cement via the hydrophilic component.
摘要:
Device and method for mixing bone cement, for injection into vertebra in particular, comprising a mixing beaker (1), manual stirring rod (6) and a cover (2), which fits in said mixing beaker (1) with a perfect fit, and the lowermost point of which features an extraction hollow cone (3) in which an extraction syringe for extraction by suction of bone cement mixed in said mixing beaker (1) is provided.
摘要:
The application relates to a vacuum mixing device (1) for bone cement, where the monomer is pressed into a mixing container (2) due to the surrounding vacuum and a gas volume present in the monomer container (10).
摘要:
A bone cement is provided that includes a solid component and a liquid component. The solid component and liquid component are mixed together to form the bone cement. After completion of the solid and liquid component mixing, the bone cement has an initial viscosity effective for manual application or manual injection onto or into a targeted anatomical location, e.g., bone, and the cement has stable viscosity range that over both time and temperature is effective for uniformly filling the targeted anatomical location, for example an osteoporotic bone or a fractured vertebral body, with minimal to no leakage of the cement from the targeted anatomical location. Additionally, both the initial viscosity and the stable viscosity of the bone cement are within a range that renders the bone cement effective for injection with a manually operated syringe or multiple syringes.
