Abstract: A surgical tool comprises a detachable tool assembly and tool actuating handle. The tool assembly comprises a tool such as scissors having jaws pivotably mounted via a pivot pin to an inner extension. An outer sleeve around the extension carries a drive pin which engages the tool. The actuating handle retains the inner extension in a fixed position but allows the tool to rotate. Moving a trigger on the actuating handle causes the outer sleeve to translate back and forth over the extension. As the sleeve moves, the drive pin engages the tool to open and close the jaws. The handle is available in a dual-port configuration in which the tool assembly may be inserted in one of two ports.
