Bone marrow harvesting device and storage methods
Bone harvesting tools and methods of use thereof are disclosed. In an embodiment, the tool comprises a chamber having a first aperture, a second aperture, an internal cavity, and a suction source fluidly connected with the chamber. The suction source is effective to generate negative pressure within the internal cavity of the chamber. The tool also has a reamer having a reaming portion, the reamer being sized to extend through the first and second apertures of the chamber, wherein the reamer is movable relative to the chamber. Additionally, the tool includes a storage container fluidly connected to the internal cavity of the chamber and effective to receive bone and/or cellular material extracted from the patient, the bone and/or cellular material being extracted during reaming a bone of the patient with the reamer.
COLLECTING AND HARVESTING CUT BONE FROM KERRISON RONGEUR
A collector includes a container body defining an interior containment space and having an open end for access, and a cap in covering relation to the open end and having an opening for receiving therein a distal end of a kerrison-type rongeur. An improvement includes the cap including a first plurality of scrapers in the form of fingers for engaging and dislodging cut bone from the cutting area of the distal end of the rongeur and a second plurality of scrapers in the form of wipers for engaging and dislodging cut bone from the cutting area of the distal end of the rongeur when the distal end of the rongeur is withdrawn through the opening from the collector, the second plurality being arranged so as to permit insertion of the distal end of the rongeur through the opening into the collector without engaging the distal end of the rongeur.
INSTRUMENTS AND INSTRUMENT KIT FOR LATARJET PROCEDURE
Disclosed is a positioning instrument that includes: two branches equipped at the proximal end thereof with an opposite jaw between which the graft is positioned, the two branches moving closer to one another by a translation movement; and a drill bush including a first hole and a second hole, separated by a distance and sized for the passage and guidance of a bone drill bit. Also disclosed are an instrument kit as well as a method for attaching a graft.
BONE SCAFFOLD IMPROVEMENTS
Bone graft scaffold arrangements are described that can be used in minimally invasive posterolateral spinal fusion. The bone graft scaffold apparatus comprise a housing which comprises a cavity for receiving bone growth promoting materials and a plurality of apertures. In use these allow bone and blood vessels to grow through the plurality of apertures to form the bone bridge between vertebrae. Further the bone graft scaffold apparatus comprise at least one opening in the housing for receiving a shaft of an orthopaedic device, such as rod linking pedicle screws, or the shaft of a pedicle screw, or another suitable shaft in another surgical procedure. The apparatus can be attached to structural components such as rods and screws and used to form a continuous scaffold between vertebras to assist in forming a bone bridge.
Manifold for medical waste collection device
Medical waste collection manifolds that that may connect to a vacuum system to create suction, such that liquid, semi-solid, or solid biological or medical waste may be collected are provided. The manifold may be configured to collect hazardous waste in a manner to ensure proper containment.
Device for severing and removing tissue parts
A device for severing and removing tissue parts (20), from a body of a living being, by means of a fixed guide rail (1, 30) along which a slide rail (6, 31) is movable, wherein the guide rail (1, 30) and the slide rail (6, 31) form, in the distal region, a cutting or punching mouth (17, 32) for severing the tissue part (20), wherein a conduit (18) for supplying a liquid is assigned to the cutting or punching mouth (17).
Coring device for preserving living tissue
Improved coring devices suitable for articular cartilage and bone, wherein the cutting device is capable of slicing through a tough protective tangential zone, delicately separating the shock absorbing columns of cells in the radial zone of the cartilage, and finally cutting into the hard underlying bone in a manner that preserves the viability of osteochondral cells. The coring device features an annulus having a flat annular cutting edge interrupted by at least one serration having neutral cutting angles. A method for concurrently removing cartilaginous and bony tissue using an improved coring device that preserves the viability of osteochondral cells.
Tissue harvesting
The present disclosure relates to a tissue collection apparatus. The tissue collection apparatus comprises a housing defining an inlet and an outlet, a first filter disposed within the housing, a second filter disposed within the housing, the second filter configured to isolate tissue particles of a desired size that pass through the first filter under the application of an aspiration force applied through the housing. A method of harvesting tissue is also disclosed.
Crafting of cartilage
The invention is directed to producing a shaped cartilage matrix isolated from a human or animal where the cartilage has been crafted to facilitate disinfection, cleaning, devitalization, recellularization, and/or integration after implantation. The invention relates to a process for repairing a cartilage defect and implantation of a cartilage graft into a human or animal by crafting the cartilage matrix into individual grafts, disinfecting and cleaning the cartilage graft, applying a pretreatment solution to the cartilage graft, removing cellular debris using an extracting solution to produce a devitalized cartilage graft, implanting the cartilage graft into the cartilage defect with or without an insertion device, and sealing the implanted cartilage graft with recipient tissue. The devitalized cartilage graft is optionally recellularized in vitro, in vivo, or in situ with viable cells to render the tissue vital before or after the implantation. The devitalized cartilage graft is also optionally stored between the removing cellular debris and the recellularizing steps.
SURGICAL INSTRUMENT FOR SCRAPING AND COLLECTING BONE PARTICLES
A surgical instrument (10) for scraping and collecting bone particles, comprising: a gripping handle (20); a blade (30) supported by the handle (20); and a collection chamber (40) of particles scraped by the blade (30), wherein the blade (30) comprises a plurality of cutting edges (320) separated from each other.
