Patent ID: 7604648

Claim:
A dissector device useful for dissecting a tissue comprising: an elongated housing comprising an elongated tubular section and having proximal and distal ends and a lumen, said distal end being operative to be inserted within a surgical incision, said housing further comprising a viewing device positioned within the lumen, wherein the viewing device is oriented to view through the distal end of said housing; a tissue spreading dissector mechanism formed upon said distal end of said housing, said tissue spreading dissector mechanism operatively transitional between: a first neutral configuration wherein said tissue spreading dissector mechanism extends from the distal end of said housing; and an operative configuration wherein said tissue spreading dissector mechanism extends outwardly beyond a circumference defined by said elongated tubular section, and said tissue spreader dissecting mechanism comprising opposed blade members configured to provide at least one void formed thereon defining a channel through which said viewing device can view through the distal end of said housing; and an actuator mechanism formed upon said proximal end of said housing operative to selectively cause said tissue spreading dissecting mechanism and tissue spreaders to selectively transition between said neutral and operative configurations.
