Abstract
A surgical instrument for spreading apart the internal organs of a patient. The instrument includes a scissors-like main body portion having a plurality of blades that open to spread apart the area being examined so that a surgical tool can be inserted therein. The instrument can be withdrawn or moved out of the area of view by allowing the surgical tool to pass through a gate formed between the spread-apart blades while maintaining the spread-apart condition of the area being examined. The blades can then be restored to their closed position after the tool is withdrawn.
