A fiber producing apparatus and method for producing fibers having at least two different dimensions or characteristics. The apparatus cuts fibers of varying length, thickness, and width by varying a cutting stroke length, using a cutting plate having different cutting blades, and applying varying pressure on a material during the cutting process. The fibers of the present invention are moldable and can be used as an implant having a structure that mimics native or natural bones. The ability to mimic natural bone improves cellular infiltration and bone growth.

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 workstation having a pair of posts on either side of a clamping plate where a donor bone may be placed on sequentially cut in three separate cutting paths. Cutting gates are attached to the posts and used to provide cutting paths that can be precisely oriented with respect to the meniscus of the donor bone part using visual alignment without any manual measurements. The graft is affixed to a machining clamp and shaved to appropriately shape the sides and form a radius on the bottom of the graft. A tibia is then prepared by using a drill guide to form a pilot hole and then to drill out a large hole for the graft. The drilled hole is expanded and shaped using a rod guide and chisel and then a rasp. The shaped graft may then be implanted into the shaped hole and sutured in place.

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.

Methods of harvesting cancellous bone and bone marrow include extracting loosened cancellous bone and bone marrowincluding a liquid component thereofto 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.

A surface contour gauge is provided for use in surgical transplantation procedures. Surface contour gauges provide quick and efficient surface contour matches between a patient's bone defect and a prepared allograft plug.

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.

The invention provides a method of making a biological disc graft. In one embodiment, the biological disc graft is useful for treating back or neck pain. In one embodiment, the biological disc graft is useful for treating any joint pain. The invention also provides a method of implanting said biological disc graft in a way that is minimally invasive and less dangerous.

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.
