There is disclosed a system and methods for safely, precisely, and efficiently cutting cadaveric bone segments into a number of dimensionally standardized pieces. One embodiment provides a jig system for use with a band saw. The jig system may include a v-shaped trough riding upon a plate and at least one rail designed to glide within a corresponding groove formed in the band saw table and stretching parallel to the blade. The trough may include a channel having a series of incremental stops extending between its proximal and distal ends. A bone-advancement wedge may be advanced proximally along the channel between the incremental stops to advance at least one bone segment within the trough toward the proximal end of the trough such that, by sliding the rail(s) within the table groove(s), a desired incremental portion of the bone segment is introduced to the blade. Other embodiments are also disclosed.

Provided is an apparatus for processing teeth in bone material, including a reactor, configured for treating said teeth by immersion in liquids, and including connection means, with a cartridge including a plurality of containers for washing and processing liquids, separated liquid-tight from each other, a reaction chamber configured for containing the teeth during processing, and the washing and processing liquids, commandable transfer means of the liquids from the containers to the reaction chamber configured for placing only one of said containers at a time in fluidic connection with the reaction chamber, ejection means of the liquids from the reaction chamber.

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.

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 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 technique for knee replacement surgery that allow for the removal of an oval oblong-shaped allograft bone and cartilage plug from a donor distal femur. The technique uses instruments including (i) sizing guides to match the recipient's femoral size and curvature to that of a donor femur (the sizing guides also acting as a wide pin placement template for the donor distal femur); (ii) osteotomes that cut the curved and straight portions of the implant shape (these may be disposable or reusable); and (iii) templates that fit over the guide pins and have openings to allow the osteotomes to cut the donor femur plug to the correct size, shape and depth. The instruments allow for a non-circular shape to be extracted from a donor femur for use in a bone-saving osteoarthritis distal femur resurfacing procedure.

The present invention relates to medical apparatuses and procedures for reconstructing a ligament. There is provided a trephine (10) comprising an adaptor (11), an elongate reamer (12) coupled thereto, and a reamer support stem (13), wherein the reamer support stem is mounted concentrically within the reamer and adaptor, and wherein at least a portion of the reamer support stem is slidably moveable about a longitudinal axis of the trephine.

The present invention relates to minimally invasive graft delivery systems and devices. The systems and devices provide a means to deliver graft material minimally invasively, such as to a spacer within a disc space. A particular system can include a cannula, a syringe and an extrusion tool. The extrusion tool can be used to extrude material from the cannula and syringe, and can have multiple modes of operation to accommodate the extrusion of materials of different viscosities.
