ABSTRACT:
A blunt dissector instrument for laparoscopic surgical protocols is disclosed which is adapted for defining an anatomical structure from investment tissue. The dissector is formed from an elongate member which extends longitudinally between a working end and a control end, and is provided with a tip region having a blunt dissector tip and a lateral dissector region. A rough surface is circumferentially disposed about the tip portion and is effective for tactilely retaining and abrading the investment tissue for its substantially atraumatic removal from the anatomical structure.
