A device is provided, including a cutting rib, the cutting rib including an arcuate portion having an outer sharp edge and a centralizer configured to receive the cutting rib through a radial slot, the radial slot forming a gap with the cutting rib. The arcuate portion of the cutting rib is formed into a profile that follows a surface of the centralizer, the outer sharp edge of the arcuate portion of the cutting rib has a wavy profile that forms a tunnel in the gap between the centralizer and the cutting rib, and the outer sharp edge of the arcuate portion of the cutting rib protrudes outwardly from the surface of the centralizer. A method for using the device to cut bone in a surgical configuration is also provided.

A method of treating soft tissue conditions. A harvesting device is provided. The harvesting device is operably connected to a tissue processing device using tubing. An aperture is formed in a bone. The bone has an interior. The harvesting device is inserted through the aperture in the bone and into the interior of the bone. The harvesting device is manipulated to dissociate connective tissue progenitor cells in the interior of the bone. Tissue is aspirated from the interior of the bone. The connective tissue progenitor cells are separated from the aspirated tissue. The separated connective tissue progenitor cells are injected in a region of a body that is experiencing a soft tissue condition to treat the soft tissue condition.

Arthroscopic devices adapted for minimally invasive procedures, such as bone augmentations and reconstructive surgery, are provided. The arthroscopic devices include a drill guide adapted for efficiently and accurately positioning pilot holes and surgical instrumentation relative to the bone; a surgical cable, such as an elastomeric surgical cable, adapted for applying a compressive force across the bone fragments after the surgical repair to promote healing; and a tensioner and crimping device for applying tension to the surgical cable and securing the surgical cable in place. A surgical procedure is also disclosed where a cerclage is applied arthroscopically by passing a member such as an elastomeric ribbon through the glenoid and a bone graft, where the member is tensioned and fixed into place to hold the bone graft in firm contact with the glenoid to facilitate healing.

A cartilage repair technique employs a cutter-tissue trap combination device to harvest cartilage tissue from a low-weight-bearing site of a subject. Cut tissue is aspirated though a lumen of a tissue cutter. The lumen includes an outer shaft having a first distal window and an inner shaft having a second distal window. Edges of the first distal window and the second distal window cooperate to provide a cutting action there-between upon rotation of the inner shaft within the outer shaft. A tissue trap coupled to the tissue cutter is configured to collect tissue shavings of a desired size to efficiently deliver the collected shavings to a repair site during surgery. The tissue trap includes a filter in a housing configured between a removable inflow chamber and a removable outflow chamber.

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 dental drill has a main body and a collecting hood. The main body has a first cutting member and a second cutting member, and both of the first cutting member and the second cutting member have a blade on two sides. A drill is formed by the first cutting member and the second cutting member with their respective bottom ends, a top end of the drill connected to a drill shank. The collecting hood has a closed end and a circular wall forming an accepting space in the collecting hood. The closed end having an engaging hole accepting the drill shank, and, a bottom inner face of the closed end has four clefts arranged in a cross shape and four pairs of the scrapers with a scraping section inbetween.

Devices and methods for an autovance intraosseous device. The autovance intraosseous device can include a trigger activated system or pressure activated system that causes a needle to advance distally for a predetermined distance. The predetermined distance ensures a needle tip extends through the bone cortex, to access the medullary cavity, without penetrating a far wall of the medullary cavity. The advancement can be driven by a spring based system or an electric motor.

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.

Various surgical tools having a movable handle mechanism including a positioning handle are disclosed. The movable handle mechanism may be configured to move forward and backward in a longitudinal direction along the housing and rotate clockwise and counterclockwise around the housing. In various embodiments, the housing may include a plurality of channels and each channel may have at least one detent. The movable handle mechanism may be configured to securely couple to the housing via one channel of the plurality of channels and one detent of the plurality of detents. At least one surgical tool may include a drill having an angled tip portion and a sleeve configured to protect adjacent structures from lateral edges of the drill bit when the drill bit is rotating. Another surgical tool may include a screwdriver having an elastic retaining clip configured to progressively release a bone screw therein at an extraction force.

Reamer instruments and related methods are disclosed herein, e.g., for reaming bone to facilitate in situ assembly of a bone anchor. In some embodiments, the instrument can include a feedback mechanism configured to alert the user when sufficient bone has been removed to facilitate assembly of the bone anchor. The feedback mechanism can be triggered by a movable shaft of the instrument that is displaced by the shank portion of the bone anchor as the surrounding bone is reamed.
