A mixing apparatus (130) for a syringe (110), the mixing apparatus comprising a dock (134) configured to receive the syringe and having an agitation component actuator (132) integral to the dock configured for magnetically coupling to an agitation component (136) of a magnetic material located within a chamber of said syringe, and configured for manipulation of said agitation component within said chamber when coupled; wherein the actuator is in the form of a drum having a series of magnets attached thereto offset in relation to one another so as to manipulate said actuation component in a reciprocating motion upon rotation of the drum.

A combination plunger, a mixing device and a mixing syringe including the same are provided. The mixing syringe includes concentric outer and inner barrels that form an outer chamber, the inner barrel having an inner chamber. The combination plunger includes a mixing plunger and a delivery plunger and a biasing means. The mixing plunger is slidably located in the outer chamber and translated by coordinated depression of the delivery plunger to transfer a first substance from the outer chamber to mix with a second substance in the inner chamber. After the mixing stage is complete, the delivery plunger is disengaged from the mixing plunger and permitted, such as by rotation, to be further depressed in the axial direction to deliver fluid contents of the mixing syringe to a recipient. The mixing syringe needle is then retracted as result of engagement by the delivery plunger and activation of the biasing means.

A container for bone cement includes a first member defining a chamber, which contains a first ingredient. The chamber also includes a second member movably coupled to the first member. The second member includes a mixing device that is movably disposed within the first chamber, and the second member defines a second chamber containing a second ingredient. The container additional includes an opening device that selectively opens the second chamber and allows the second ingredient to enter from the second chamber into the first chamber. The mixing device is movable within the first chamber to promote mixing of the first ingredient and the second ingredient to prepare the bone cement. A corresponding method of preparing bone cement is also disclosed.

Device for the mixing of polymethylmethacrylate bone cement and for storing a monomer liquid and a cement powder as starting components of the bone cement, comprising a cartridge having an internal space closed on one side by a mobile dispensing plunger; a monomer container for a monomer liquid and/or a connector for attachment of a monomer container which can be opened in the device so that the monomer liquid flows from the monomer container into the device; and a connecting conduit through which the monomer liquid can be guided into the internal space of the cartridge; having a pumping plunger that can be shifted axially in the hollow cylinder arranged in the hollow cylinder, which can be used to push monomer liquid from the hollow cylinder through the connecting conduit into the internal space of the cartridge by actuating the pumping plunger.

A powered surgical tool that includes a housing with a head and a handle that extends from the head. An electric motor is disposed in the head. A trigger extends from the handle. There is a void space in the handle. A plate separates the motor from the handle. Internal to the handle void space there is a rotor sensor and a control circuit. The rotor sensor is able to monitor the magnetic fields emitted by the motor rotor and that pass through the plate. The control circuit receives signals from the rotor sensor representative of the rotational orientation of the rotor and is further able to monitor the actuation of the trigger. Based on the rotor orientation signals and the actuation of the trigger, the control circuit generates signals that result in the selective generation of power signals to the motor rotor.

A manual mixer serves to facilitate mixing and agitating materials for use during surgery. For example, the manual mixer includes a body portion defining an interior area, a mixing assembly provided in the interior area of the body portion, a crank assembly for actuating the mixing assembly, and a valve assembly. The mixing assembly serves to mix and agitate the materials provided in the interior through rotation of a plunger portion and a spring attached thereto, and through upwards and downwards movement of the plunger portion in the interior area. Rotation of the crank assembly serves to rotate the plunger portion and the spring attached thereto, and effectuate upwards and downwards movement of the plunger portion. The valve assembly can be opened to facilitate dispensing of the materials from the interior area.
