Hemorrhoids treatment method and associated instrument assembly including anoscope and cofunctioning tissue occlusion device
First Claim
1. A method for the treatment of hemorrhoids, comprising:
- providing an anoscope and a hemorrhoid occlusion device, said anoscope including a hollow body having a sidewall provided with a window, said hemorrhoid occlusion device having a distal end provided with a pair of jaws, at least a distal one of said jaws including a clamping member;
inserting said anoscope into an anal canal;
manipulating said anoscope so that hemorrhoidal tissues protrude through said window into said anoscope;
inserting said jaws of said occlusion device into said anoscope;
after the protruding of said hemorrhoidal tissues through said window and after the inserting of said jaws into said anoscope, manipulating said occlusion device so that said jaws are located on opposite sides of the hemorrhoidal tissues, the manipulating of said occlusion device including manipulating said occlusion device so that one of said jaws is located on a far or distal side of the hemorrhoidal issues, between the hemorroidal tissues and an inner or distal end of said anoscope, and so that another of said jaws is located on a near or proximal side of the hemorrhoidal tissues, between the hemorroidal tissues and an outer or proximal end of said anoscope;
thereafter closing said jaws to clamp the hemorrhoidal tissues; and
subsequently operating a tissue occlusion component of said occlusion device to permanently constrict a portion of said hemorrhoidal tissues.

Abstract
A surgical instrument assembly for the treatment of hemorrhoids includes an anoscope and a hemorrhoid occlusion device. The anoscope includes a hollow body closed at a distal end and at least partially open at a proximal end to define a longitudinal channel. The hollow body has a sidewall provided with a window spaced from the distal end and the proximal end. A shutter member is slidably attached to the hollow body for selectively covering the window during an insertion operation and for opening the window to allow hemorrhoidal tissues to protrude through the window into the anoscope. The hemorrhoid occlusion device includes an instrument shaft provided at a distal end with two jaws, at least one of the jaws including a C- or U-shaped clamping member movable alternately away and towards the other of the jaws for clamping and occluding hemorrhoidal tissues protruding through the window into the anoscope.
