There are disclosed systems and methods for safely and effectively removing the articular cartilage and cortical bone layers from an articular surface of a human cadaveric femoral head. One embodiment includes an osseous-sanding accessory system installed upon a conventional band saw having a motor and a cabinet that houses a pulley coupled with a primary drive shaft rotated by the motor. The accessory system may include a threaded drive shaft coupled with the primary drive shaft, a grinding disk having an abrasive surface and affixed about a distal end of the threaded drive shaft, and a removable accessory table mounted to the band saw below the grinding disk. When the motor rotates the primary drive shaft, and thus the threaded drive shaft, the grinding disk rotates relative to the accessory table and abrades osseous tissues introduced to the abrasive surface of the grinding disk. Other embodiments are also disclosed.

Methods, apparatus and kits for preparing a medical mixture are disclosed. A method of preparing the medical mixture includes introducing a material into a tray, transferring the material from the tray to a scooper, releasably securing the scooper to the tray, and introducing a tubular member defining a lumen into the scooper such that the material within the scooper enters the lumen. A mixing apparatus includes a tray comprising a body defining a mixing receptacle configured to receive a material, a scooper having a proximal end with a proximal opening and a distal end with a distal opening, and a connector configured to releasably secure the scooper to the tray. A kit includes a tubular member, a stylet, a tray, and a scooper.

Systems and methods for delivering bone graft material, which utilize a graft material cartridge. The bone graft delivery system comprises an outer delivery unit and a graft material cartridge. The bone graft delivery system is configured to provide a mechanism that loads graft material through a delivery tube and not at the end or outside of it.

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.

A system and method of processing bone is disclosed. A tissue separator is utilized to separate tissue comprising at least one of muscle, periosteum and connective tissue from bone in a safe, sterile and efficient manner. In one aspect, the particle reducer can include an impeller positioned with respect to a cutting surface on a drum. At least one of the impeller and the drum is rotated by a power source such that harvested tissue frictionally engages the cutting surface. In another aspect, a source of pressurized fluid can be directed at tissue to separate bone from non-bone tissue.

A milling module (60) for converting bone stock into bone chips comprises a shell (34) adapted for releasable attachment to a base module (32). The shell has an inlet opening (152) through which bone stock is introduced into the shell and an outlet opening (96) through which bone chips are discharged from the shell. A milling element (170) is moveably disposed in the shell between the inlet opening and the outlet opening for converting bone stock into bone chips. The shell includes abase (62) adapted for releasable attachment to the base module. The base includes the outlet opening and a lid (126) removably attached thereto. The lid includes the inlet opening of the shell. The base and the lid are collectively configured so that removal of the lid from the base allows the milling element to be accessed.

A bone mill includes a housing, at least a first bone milling tool, a proximal bearing sleeve, and a distal bearing sleeve. The housing defines a work chamber. The work chamber has a first axial end, a second axial end, a feed input opening, and an output opening. The bone milling tool is configured to be disposed within the work chamber, and extends at least from a first axial end to the second axial chamber. The proximal bearing sleeve is supported by the housing proximate the first axial end, and a distal bearing sleeve supported by the housing proximate the second axial end. The proximal bearing sleeve and the distal bearing sleeve support the bone milling tool and allow rotation of the bone milling tool within the work chamber about an axis.

The actuation of the mill element converts the cleaned bone into bone chips.

Systems and methods are disclosed for harvesting tissue from a donor site. Exemplary embodiments include a first and second conduit through which a flexible saw component is guided. Certain embodiments include a mechanism which facilitates insertion of the flexible cutting member component parallel to the transverse plane and slicing the graft parallel to the coronal plane to extract the graft.

A bone cleaning assembly with cleaning elements that remove soft tissue from bone stock. The module also includes a clearing element that is periodically urged against the cleaning elements to remove bone stock trapped by the cleaning elements from the cleaning elements.
