A system for cleaning bone that includes a base unit with a motor, a cleaning head with a cleaning element and a mill head with a mill element. Both the cleaning head and the mill head are designed to be coupled to the base unit. Both the cleaning element and mill element have features that facilitate their coupling to the motor. When the cleaning head is attached to the base unit, a motor in the base unit rotates the cleaning element to remove soft tissue from the bone so as to clean the bone. The mill element is placed on the base unit and the cleaned bone placed in the mill head. The actuation of the base unit motor results in the actuations of the mill element. The actuation of the mill element converts the cleaned bone into bone chips.

System for processing bone stock including a bone cleaning head, a bone milling head and base that powers both the cleaning head and the milling head

A device () for collecting and processing bone fragments is disclosed. The device comprises a chamber member (), a press member (), an intake port (), and a vacuum port (). A compression surface () and a filter support surface () configured to support a filter are defined by said chamber and/or press member. The intake port is on the chamber and/or press member and is configured to receive a composition comprising bone fragments. The vacuum port is on the chamber and/or press member. The chamber member and the press member are rotationally coupled with one another. The composition is acquired through the intake port and collected between the compression surface and the filter support surface. The application of rotational force to the chamber and/or press member in a first direction moves the compression surface and the filter support surface together to compress the composition therebetween to compact, and further remove filtrate from the composition.

Bone fragment collector and processor

A mobile cart that holds a bag for receiving solid waste generated during a medical or surgical procedure. The cart includes a sensor that monitors whether or not an object containing metal is placed in the bag. A processor monitors the signal output by the sensor. If the sensor signal indicates that an object with a minimal amount of metal is placed in the bag, the processor momentarily asserts an audible alarm and continuously asserts a light alarm. The light alarm remains asserted until turned off. If, while the light alarm is on, the sensor signal indicates a second object with the minimal amount of waste is placed in the container, the processor again momentarily asserts the audible alarm. This provides notice that it may be necessary to investigate the contents of the bag to determine if not one but two or more objects were inadvertently discarded.

A system for cleaning and milling bone to form bone chips. The system includes a shell into which bone stock is introduced. Internal to the shell is a cleaning element that removes soft tissue and other material surrounding the bone stock. The cleaned bone stock is transferred through an opening in the shell to a mill unit. The mill unit has a milling element against which the bone is disposed. The milling element, when actuated coverts the bone stock into bone chip. A motor drives both the cleaning element and the mill element. The shell and mill unit may be part of a head unit. The head unit is removably attached to a base in which the motor is disposed.

A solid medical waste collection system for collecting solid medical waste. The system includes a mobile cart with a bag for storing the waste. A pre-detection apparatus detects metal-containing objects prior to placing them inside the bag to reduce costs to the facility in which the cart is employed. The system may also include a bag-tensioning mechanism for securing the bag to the cart.

A bone cement mixing and delivery assembly is disclosed for mixing a powdered copolymer and a liquid monomer to form a bone cement and delivering the bone cement. The assembly includes a cartridge having a distal end and a proximal end and defining a mixing chamber between the distal end and the proximal end. A transfer mechanism having a cap and a stem supporting a piston and a plunger is connected to the distal end. The transfer mechanism includes a first advancement mechanism for advancing the piston and plunger in unison and a second advancement mechanism for moving the plunger independent of the piston. The assembly further includes a removable handle having a shaft for attachment of a mixing blade and a quick-release connector and a release button for locking and unlocking the mixing blade from the removable handle.

A delivery apparatus for injecting cement from a cartridge includes a cradle, a cartridge, a button, and a threaded rod. The cradle has an axial cavity extending therethrough for supporting the cartridge of cement. The cartridge dispensing mechanism is coupled to the cradle. The button includes threads and defines an axial bore. The button is moveable into and out of threaded engagement with the threaded rod. The threaded rod extends into the axial cavity of the cradle.
