An anoscope adapted for the suturing of hemorrhoids during a hemorrhoid removal procedure is disclosed. The anoscope has a distal conical tip, a channel body extending proximally from the distal conical tip and a flange radiused outwardly from the channel. A slot is formed in the channel body and runs longitudinally from the distal conical tip through the flange and is flanked by a pair of mutually opposed finger wings that extend out from the flange. The finger wings each have a distal finger wing tip and a concave surface embedded within the finger wing tips. The concave surfaces are sized for the placement of a finger of a user therein.
