Patent ID: 8131380

Claim:
A surgical tool for use in rectal inspection and surgical removal of hemorrhoidal tissue therefrom, said surgical tool comprising: a) an anoscope having a substantially conical shape with a proximal end and a distal end wherein said proximal end is larger in diameter than said distal end, and further having a first slot near said proximal end and a second slot near said distal end, said second slot being located 90 degrees from said first slot; b) an obturator also having a substantially conical shape with a proximal end and a distal end, said obturator being of a size smaller in diameter than said anoscope so that said obturator fits within said anoscope, said obturator including a slot formed in one side thereof beginning at the proximal end; c) a cylindrical shaped light cover with a longitudinal axis and having an open proximal end and a closed distal end, said light cover including a flange extending around the periphery near said closed end, said flange being disposed at an angle with said longitudinal axis and including a groove around the periphery thereof for engaging said first slot of said anoscope, said closed end further comprising a receptacle that comprises a lens in one end thereof, said receptacle being disposed for receipt of a light source, whereby light is disbursed within said surgical tool for enabling inspection and surgical operations therein when a light source is inserted into said light cover, and d) a monopolar probe passing through the obturator and exposed at a distal end of the obturator slot and at the second slot of the anoscope so that tissue captured in the second slot can be excised wherein the probe comprises: a base having a proximal end and a distal end, wherein the base is comprised of a water-degradeable material; extending from the distal end of the base, at least one elongated monopolar probe electrode comprising a proximal end and distal end, wherein the distal end terminates in a distal tip adapted for electricity-conducting engagement with a hemorrhoidal lesion; and a keying block extending from the proximal end of the base configured for engaging the probe base to a handpiece in electricity conducting engagement.
