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.

Anoscope for hemorrhoidal surgery

A circular sapling instrument for the removal of hemorrhoids has a stapling end effector having a casing, a hollow staple driver within the casing, an annular blade having an open distal end is located within the staple driver, and a elongated interior drive shaft is reciprocable within the staple driver and the annular blade. A first inner chamber is defined between the staple driver and the interior drive shaft, and a second inner chamber is defined between the annular blade and the drive shaft. The first chamber communicates with the second chamber. The casing has an exterior surface and a substantially unobstructed passageway extends within the casing surface, into the first inner chamber, into the second inner chamber, and through the open distal end of the second inner chamber for insertion and withdrawal of a surgical instrument therethrough.

Circular stapler for hemorrhoidal surgery

A method for using a circular stapling instrument for the removal of hemorrhoids is disclosed. The circular stapling instrument has a stapling end effector having a stapling head assembly and an anvil assembly movable from an open position spaced away from the stapling head to a closed position adjacent to the stapling head. A first inner chamber and a second inner chamber communicate within the stapling head assembly wherein the second inner chamber has an open distal end when the anvil is in an open position. A substantially unobstructed passageway extends from an exterior casing surface of the stapling head assembly through the first inner chamber, through the second inner chamber, and through the open distal end of the second inner chamber. A suture is placed into the hemorrhoid of a patient and the open stapling end effector is placed into the anus of a patient. The open stapling end effector is positioned with the suture between the stapling head and the open anvil assembly and a surgical instrument is placed into the passageway to engage the suture through the open distal end of the second chamber. The suture is withdrawn out of the passageway with the surgical instrument. The suture is pulled by the surgeon to draw the hemorrhoids into the open distal end of the stapling end effector and into the first and second inner chambers. The open anvil is closed and the circular stapling instrument is fired to staple and cut the hemorrhoids. The circular stapling instrument and the hemorrhoids are then removed from the patient.
