Surgical blade package

A surgical blade package facilitates the mounting of a surgical blade on to the forwardly-projecting cleat on a scalpel handle; and following use in the O.R., the surgical blade package facilitates stripping the used blade off the scalpel for disposal in a sharps container. The cleat is inserted beneath the rear end portion of the blade, and between the blade and the bottom wall of the blade package; and forward and upward movement of the scalpel snaps the blade on to the scalpel in a continuous movement. The opposite procedure is used to demount the used blade from the scalpel and encase it in the original blade package for disposal in a sharps container.

Ultrasonic surgical blade with improved cutting and coagulation features

The present invention is directed to an ultrasonic surgical blade including a top surface, a bottom surface and a cutting-edge. The cutting-edge is defined by a cutting-surface intermediate the top surface and the bottom surface, and the top surface has a width greater than the width of the bottom surface. The blade may be straight or curved. In one embodiment of the invention, at least a portion of the cutting-surface is substantially parallel to at least a portion of the top surface. In still another embodiment of the invention first and second side-walls intersect the top surface to form first and second cutting-edges that may be sharp or blunt. Alternately, a second cutting-edge may be defined by a second cutting surface intermediate the top and bottom surfaces. Depending on the angle between the intermediate cutting-surface and the top surface, the cutting-edge may be sharp or blunt. In yet another embodiment of the present invention, a central ridge is provided on the bottom surface of the blade to eliminate blade burrowing and improve precision during coagulation. The cutting-edge is optimized to increase cutting speed of the blade while providing desirable hemostasis. The invention is of particular benefit for breast surgery, due to its cutting and coagulation characteristics.
