A device for shaping and cutting a bone graft comprises a main body (2) extending along a longitudinal axis (X) from a lower end (2i) to an upper end (2s) and having inside it a housing (3) for the insertion of the bone graft (100) to be shaped, an upper opening (4), located at the upper end (2s), for the insertion of the bone graft (100) into the housing (3), a lower support (5) designed to support the bone graft and an upper surface (6) defining a cutting plane, placed at the upper end (2s) and containing said upper opening (4) which is inclined with respect to the longitudinal axis (X) by an angle (a) ranging between 90° and 30°, preferably between 90° and 60°.

A method for the execution of implants, surface finishes of implants the manufacture of a particulated bone material, and with the particulated bone material obtained, a method for the manufacture of a bone-biopolymer filament may be performed, to obtain a bone-biopolymer filament. The filament may be used, for example, in a method for the manufacture of implants by 3D-printing. A method for the manufacture of bone implants by machining; once a bone implant has been obtained by the method of manufacture of implants by 3D-printing or the method of manufacture of bone implants by machining, it is subjected to a texturisation to enable the osseointegration thereof.

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.

Techniques are described for bone-graft harvesting in orthopedic surgery. Processing circuitry may obtain a virtual model of a bone graft to be harvested from a donor bone, wherein the virtual model of the bone graft specifies a volume of the donor bone to be harvested as the bone graft; and output for display, via a visualization device, a graphical representation of the specified volume to be harvested relative to a portion of the donor bone viewable via the visualization device.

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 bone grinder is provided herein. The bone grinder may have a grinding chamber, an intermediate zone, and a primary cutting element and a secondary cutting element. The intermediate zone may have a first wall and a second wall within the grinding chamber, and the intermediate zone may separate the primary cutting element from the secondary cutting element. The first wall and the second wall may slope inward such that a distance between the first wall and the second wall generally decreases from the primary cutting element to the secondary cutting element. The primary cutting element and the secondary cutting element may be positioned within the grinding chamber to sequentially perform primary cutting operations and secondary cutting operations on a bone. A drive mechanism may operatively engage the primary cutting element and the secondary cutting element.

A bone cleaning assembly (102, 602) with cleaning elements (690, 724, 1230, 1264) that remove soft tissue from bone stock. The module also includes a clearing element (778) that is periodically urged against the cleaning elements to remove bone stock trapped by the cleaning elements from the cleaning elements.

Methods of harvesting cancellous bone and bone marrow include extracting loosened cancellous bone and bone marrow—including a liquid component thereof—to a collection container that has a first cup and a suction port to which a suction source is connected. After extraction, the suction source is disconnected and a lid of the collection container is removed and replaced with a lid having a plunger with a press head that is configured to filter the extracted liquid by depressing the plunger toward a bottom of the first cup. The filtered liquid is poured through a suction port into a second cup while depressing the plunger, thereby separating the liquid from a semi-solid mass of cancellous bone that remains. The bone is extracted through a cortical opening in the femur, tibia, or calcaneus, or from an intermedullary canal that is preferably formed by reaming of the tibia using an orthopedic reamer.

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

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.
