Abstract: The inventive technology describes to a novel surgical device having a high-speed rotating hollow cutting needle capable of longitudinally cutting, sampling, removing and/or coring targeted tissue pathologies as well as the efficient collection and/or disposal of said tissue pathologies. In particular, the inventive technology may be suitable for application on lesions near the skin, and/or pathologies internal to the body, and perhaps even especially for procedures performed in conjunction with image guidance, particularly active X-ray, computerized tomography (CT), magnetic resonance imaging (MRI), and/or ultrasound scans, where the presence of a large electro-magnetic field may impose significant constraints on the design and operation of mechanical mechanisms.

Abstract: A surgical screw and driver arrangement whereby the end of the driver is vertically inserted and removed from the slotted end of the surgical screw and whereby the end of the driver is attached to and removed from the slotted end of the surgical screw by a quarter turn in the clockwise and counterclockwise directions. The driver includes an inner shaft connecting with a center locking cam at one end of the driver and an outer shaft that connects with a pair of blades, one on each side of the locking cam. The surgical screw includes a slotted head at one end and a tapered threaded rod attached to the head. A pair of dovetail slots extending perpendicular within the slotted head receives the locking cam when the driver inner shaft is rotated a quarter turn clockwise to fasten the surgical screw to the end of the driver.

Abstract: A system for and methods of easily and securely inserting and removing a fastener usable during orthopedic surgery to promote proper healing of injured bone are disclosed. In at least one embodiment, the invention provides a system for positive, complete tri-modal retention of a bone media fastener element by a bone media fastener driver element so that three types of positional divergence of the driver relative to the fastener—bi-axial, bi-rotational, and bi-lateral—may be prevented. At least one embodiment of a bone media fastener apparatus may comprise a shaft element, a threaded bone engagement element, and a head element that itself may comprise a fastener-side, positive, complete tri-modal retention element that is engageable with a driver-side, positive, complete tri-modal retention element of a bone media fastener driver element to prevent bi-lateral divergence, bi-rotational divergence, and bi-axial divergence.
