A method for treating cartilage defects including providing a placental membrane preparation that comprises ground or minced placental membranes and optionally, a ground or minced cartilage and/or biocompatible glue, and introducing the preparation to a cartilage defect within a skeletal joint. The cartilage defect may comprise a hyaline cartilage defect, such as a chondral defect, or meniscal defect. The treatment may be provided in combination with other treatments such as marrow stimulation treatments and surgical repair treatments using sutures or other fixation techniques. The preparation promotes the regeneration of cartilage within the skeletal joint.

An apparatus for transforming teeth into bone material, which is suitable to treat the teeth by immersion in liquids and includes a reactor device including a contactor, a reaction chamber, an ejection chamber, a cartridge including a plurality of containers for the processing and washing liquids, separated liquid-tight from each other, a fragmentation device suitable to fragment teeth, a guide suitable to detachably connect the cartridge and the fragmentation device to the apparatus, and a movement device suitable to detachably connect at least partially the reactor device and allow it to sequentially withdraw the teeth from the fragmentation device and the liquids from the cartridge.

The present invention relates to cartilage morcellator for cutting various kinds of cartilage (including costal cartilage and the like) into small pieces by using an elevating-type cutting knife having a simple configuration such that same can be supplied to a plastic surgery part. The cartilage morcellator comprises: an upper body (2) and a lower body (3), which are separated from/coupled to each other; an upper groove (4) and a lower groove (5) formed on the upper and lower portions of the upper body (2), respectively; an isolation portion (6) formed between the upper groove (4) and the lower groove (5); a through-hole (7) formed perpendicularly at the center of the isolation portion (6); an elevating rod (8) fitted to the through-hole (7); a morcellating knife (10) fixed to the bottom surface of the elevating rod (8), the morcellating knife (10) having a zigzag-shaped knife portion (102) and a blade portion (103) formed thereon; a spring (11) fitted to the outer periphery of the elevating rod (8); and a striking portion (12) fastened to the upper portion of the elevating rod (8) and elastically supported by a spring (11). The cartilage morcellator further comprises: a morcellation chamber (13) formed in the lower body (3) and provided with a bottom; a prop plate (14) formed on the bottom of the morcellation chamber (13); a first gripping portion (21) formed on the outer periphery of the upper body (2) so as to have an outer diameter smaller than the outer diameter of the upper end of the upper body (2); a second gripping portion (22) formed to have an outer diameter larger than the outer diameter of the first gripping portion (21); and a plate body (101) having a predetermined thickness, which is fixed to the upper portion of the knife portion (102).

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 device for collecting a bone graft material comprises a canister extending defining a filter-receiving space therein, the canister including a connection for connecting to a vacuum source, a proximal end of the canister including a first locking feature and a filter element sized and shaped to be received within the filter-receiving space of the canister, the filter element including a channel extending therethrough, the channel defined via a mesh material and a proximal end of the filter element including a second locking feature releasably engageable with the first locking feature of the canister via a rotation of the filter element about a longitudinal axis thereof relative to the canister in combination with an extractor sized and shaped to be received within the channel of the filter element, the extractor defining a graft material receiving space therein and being releasably engageable with the extractor.

A device (10) for collecting and processing bone fragments is disclosed. The device comprises a chamber member (12), a press member (14), an intake port (16), and a vacuum port (18). A compression surface (20) and a filter support surface (22) 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.

A bone milling device for grinding bone during a bone grafting procedure including a pair of opposing dead stops, one or more provided on a rotating plate of a rotatable mill and one or more provided on a stationary plate to prevent adhesion of respective arrays of grinding teeth.

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.
