An automatic machine for processing a tooth by a graft material includes: a body including a power supply supplying power to a controller, which controls the amount of supply solution and operation of a suction pump and a vibrator, and having a receiving space; a receiving container disposed in the receiving space, having a space for keeping a tooth bone graft material, and including a net and a cover having a handle; a cylinder having a space for keeping the receiving container, and inlets and outlets for supplying and discharging the supply solution; a vibrator fastened to the cylinder and generating vibration of 1 to 100,000 VPM; a supplying container supplying the supply solution to the cylinder; and a suction pump discharging solution in the cylinder to a discharging container.

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 mill head for replaceable attachment to a base so as to collectively form a bone mill. The mill head includes shell with: a first opening in which bone stock is introduced into the head; and a second opening through which the bone chips are discharged. A cutting device is mounted in the shell to both rotate and move laterally. Attached to the cutting device are coupling features for engaging a drive spindle able to rotate the cutting device. Also attached to the housing is an alignment feature. The alignment feature engages a complementary alignment feature associated with the drive spindle so as a result of the engagement of the alignment features, the cutting device moves within the shell so that the cutting device coupling features are positioned to engage the drive spindle.

A shaped cartilage matrix isolated from a human or animal where the cartilage has been crafted to facilitate disinfection, cleaning, devitalization, recellularization, and/or integration after implantation. Also, a process for repairing a cartilage defect with the cartilage matrix. The matrix is in the form of an osteochondral plug including a cartilage cap ad subchondral bone, wherein one or more gaps, slats, bores, or channels extend through the tidemark at the interface between the cartilage cap and the subchondral bone.

A cleaning module for cleaning bone stock used in surgical procedures. The cleaning module includes a shell. The shell defines a void space to receive the bone stock. A cutter is rotating mounted in the void space. A shaving tube, also able to rotate, is coaxially disposed about the cutter. The cutter and shaving tube have complementary edges. A drive assembly rotates the cutter and shaving tube at different speeds, at different times or in different directions relative to the cutter. As a result of the rotation of the cutter and shaving tube soft tissue adhering to the bone stock is cut away from the bone stock by the relative rotating of the cutting edges of the cutter and shaving tube.

A mill head for replaceable attachment to a base so as to collectively form a bone mill. The mill head includes shell with: a first opening in which bone stock is introduced into the head; and a second opening through which the bone chips are discharged. A cutting device is mounted in the shell to both rotate and move laterally. Attached to the cutting device are coupling features for engaging a drive spindle able to rotate the cutting device. Also attached to the housing is an alignment feature. The alignment feature engages a complementary alignment feature associated with the drive spindle so as a result of the engagement of the alignment features, the cutting device moves within the shell so that the cutting device coupling features are positioned to engage the drive spindle.

A cleaning module for cleaning bone stock used in surgical procedures. The cleaning module includes a shell. The shell defines a void space to receive the bone stock. A cutter is located within the void space. A shaving tube is coaxially disposed about the cutter to move at different speeds and/or directions relative to the cutter. When actuated, the cutter rotates to clean the bone stock by cutting soft tissue from the bone stock. A tumble plate reorients the bone stock, while an arm moves across the tumble plate from a disengaged position to an engaged position to press the bone stock into the cutter through a window in the shaving tube. A drive assembly actuates the cutter, shaving tube, arm and tumble plate.

A mill head for replaceable attachment to a base so as to collectively form a bone mill. The mill head includes: a first opening in which bone stock is introduced into the head; a cutting device that converts the bone stock into bone chips; a second opening through which the bone chips are discharged; and a third opening through which a motor integral with the base is attached to the cutting device. Internal to the mill head are containment rings. The containment rings prevent the discharge of material through the third opening. The containment rings are services the internal component of the mill head on which the cutting device rests.

Bone matrix compositions having nanoscale textured surfaces and methods for their production are provided. In some embodiments, bone matrix is prepared for implantation and retains nanoscale textured surfaces. In other embodiments, nanostructures are imparted to bone matrix wherein collagen fibrils on the surface of the bone matrix have been compromised, thus imparting a nanoscale textured surface to the bone matrix. Generally, these methods may be applied to mineralized or demineralized bone including partially or surface demineralized bone.

There is disclosed a system and method for dispersing sterile water from a circulating high-purity water system to a processing field containing allograft tissue. One embodiment includes a fluid inlet that is fluidly coupled with and configured to receive sterile water from the water system. The dispersion system also includes at least first and second fluid outlets that are selectively operable to deliver respective first and second fluid streams into different areas of the processing field. At least one of the first and second fluid outlets may be associated with a regulator valve configured to provide an adjustable flowrate to conserve water pulled from the circulating water system to meet the needs of the application taking place within the processing field. Other embodiments are also disclosed.
