摘要:
A case for storing medical instruments contains a rotating bracket for holding the instruments. The bracket is connected to the tray and hinged lid of the case via a movable frame, and the bracket movement is controlled by opening and closing of the lid. When the lid is closed, the bracket points the tips of the instruments downward to minimize water collection; and when the lid is opened, the instrument holding bracket rotates so that the instruments it holds are moved to a vertical position, facilitating instrument selection.

A tool for delivering bio-compatible solid, fluid or mixed solid and fluid substances to an operating site within a patient. The tool has a tubular body or barrel with a central longitudinal through hole and a flow control valve for selectively allowing material to flow from a holding chamber within the barrel through an extender tip to a dispensing end of the tool. A plunger having a piston at one end may be inserted through the dispensing end of the barrel and drawn distally to aspirate material into the holding chamber using a syringe attached to the proximal end of the barrel, after which the valve is closed to retain the material in the chamber. The plunger, which fits into the through hole from either end of the barrel, is then removed and re-inserted into the proximal end of the barrel, the barrel valve is opened, and the plunger is pushed to move the material in the holding chamber through the extender tip and out the distal end of the barrel. An optional rod and multi-pronged blade mixing assembly may be inserted into the proximal end of the barrel to mix stored material after it is aspirated into the holding chamber and before it is dispensed.

A multifunctional ruler and protractor tool with the ability to form and scale a near infinite number of geometric shapes. The tool comprises both a standalone ruler and protractor unit. Rulers are capable of being added to each other successively, creating straight ruler assemblies of virtually any length. The protractor unit can be slid onto a single ruler or a straight ruler assembly containing any number of consecutively connected rulers, and is capable of fastening another ruler to its sides by a quick connect/disconnect mechanism. The protractor component of the protractor unit pivots, allowing for the creation of angles between rulers that are laterally fastened and slidably engaged to it. The sliding lock on the protractor unit can arrest both rotational and translational motion of the protractor unit along any ruler, if it is manipulated to do so. Multiple rulers and protractors can be connected to form both open and closed, regular and irregular, polygons, and other sided geometric shapes. Geometric configuration can be scaled to larger or smaller sizes.
