Abstract

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.

Claims

1. An anoscope adapted for suturing of internal hemorrhoids in a hemorrhoid removal procedure, said anoscope being substantially symmetrical about a longitudinal axis and comprising:

a distal conical tip;

an elongated channel body extending proximally from said distal conical tip;

a flange extending from said channel body, said flange radiused outwardly from said channel body;

a slot formed in said channel body, said slot extending from said distal conical tip through said flange;

a pair of mutually opposed finger wings extending from said flange, said finger wings flanking said slot, each of said finger wings having a distal finger wing tip, and said finger wing tips each having a concave surface embedded therein, wherein said concave surfaces are sized for placement of a finger of a user therein.

2. The instrument of claim 1 wherein said concave surfaces have at least one texture ring raised thereon, said texture ring reducing slippage of the finger placed within said concave surfaces.

3. The instrument of claim 2 wherein said concave surfaces are appropriately spaced from each other for the insertion of a thumb into one of said concave surfaces and an index finger into the other of said concave surfaces.

4. The instrument of claim 2 wherein said concave surfaces are appropriately spaced from each other for the insertion of a thumb into one of said concave surfaces and a middle finger therein into the other of said concave surfaces.
