    摘要: A bone screw driving system includes a screw having a head and a shaft extending from the head. The screw includes a stepped opening extending in the shaft that includes a first portion and a second portion having a greater cross-sectional dimension than the first portion. The bone screw driving system further includes a screw driver having a driver shaft that defines a tip configured to engage the screw head. The driver further includes a pin extending from the tip and sized to fit within the opening. The pin includes an abutment movable to a locked configuration in the second portion of the opening, wherein the abutment defines a cross-sectional dimension greater than that of the first portion of the opening.

    摘要: A process for preparing an alginate rope, which process comprises the steps of: (a) extruding an aqueous solution of a water soluble alginate into a coagulation bath; (b) contacting the extruded water soluble alginate with a source of a cation capable of forming a water insoluble alginate salt so as to produce a tow of water insoluble alginate fibers; (c) twisting the water insoluble alginate fibers of the tow; and (d) stretching the fibers up to 250% of their original length. The alginate rope prepared according to the process of the invention may be used as a surgical pack material or in the treatment of cavity wounds.
