Abstract: Disclosed is a bone fixation screw structure, particularly a bone fixation screw structure including a receiver configured to provide a space in which a bone screw is inserted into the lower end thereof, a pair of openings formed at facing sides of the receiver and provided in an open form along a longitudinal direction of the receiver, and a pair of closures formed at remaining facing sides of the receiver and provided in a closed form along the longitudinal direction of the receiver, thereby enabling a user to easily change a closed-type receiver to an open-type receiver and thus fundamentally preventing interference with a rod or an insert component.

Abstract: A system for increasing rates at which fluids may be manually forced through injection/aspiration elements, such as catheters and needles, includes the injection/aspiration elements, as well as a syringe including a pair of crossed handles, one associated with the barrel of the syringe, the other associated with the plunger of the syringe, to provide a mechanical advantage. The system may include and injection/aspiration element of small (e.g., 0.052 inch or smaller) inner diameter and small outer diameter (e.g., 5 French or less). Such systems enable the use of a single hand to hold and operate a syringe in a variety or procedures, including angiography, angioplasty, discography, glue/cement injection, and a variety of aspiration procedures (e.g., biopsy, sampling, media removal, etc.).

Abstract: A syringe includes a barrel and a rotatable element on the barrel; for example at a proximal location along the length of the barrel. The rotatable element rotates at least partially around the barrel. When a handle is associated with the rotatable element, the barrel may rotate as the handle his held substantially stationary or the handle may be rotated while the barrel and any peripheral device secured thereto remain substantially stationary. When handles are associated with a rotatable element that may be removed from a barrel, a barrel that is disassembled from the rotatable element may be replaced with another barrel of the same or a different configuration. Methods of using a syringe with a rotatable element on a barrel thereof are also disclosed.
