Abstract

The invention discloses an internal orifice excision drainage device for treating anal fistula. The internal orifice excision drainage device comprises an anoscope and a broach and is characterized in that the anoscope comprises an anoscope body, a guide part and a handle, wherein the guide part is arranged at the bottom of the anoscope body, the handle is arranged on the right side face of the anoscope body, a first V-shaped groove and a second V-shaped groove are formed in the anoscope body, the first V-shaped groove is formed in the front side face of the anoscope body, and the second V-shaped groove is formed in the rear side face of the anoscope body; and a V-shaped blade is arranged on the edge of the broach, and the handle is arranged at the bottom of the broach. After an internal orifice is determined, the anoscope is placed in an anal tube, the top end of the opening of each V-shaped groove is placed above the internal orifice, the internal orifice is excised to the anal margin through the bevel broach, the internal orifice is completely excised and forms a double-V shape, drainage is sufficient, and the incision of the anal margin can extend properly so that drainage and healing can be facilitated. A simple operation instrument is provided for an anal fistula treatment operation, and the success rate of the anal fistula operation is greatly increased.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an internal orifice resection and drainage device for treating anal fistula. Background technique [0002] Anal fistula is the abbreviation of anorectal fistula, which is the sequelae of abscess ulceration or incision drainage that occurs around the anorectum. Anal fistula is a disease with two stages. A typical anal fistula is a smooth and complete duct with one end in the anal sinus and the other outside the anal verge, or in the rectal wall. Atypical anal fistula generally only has an internal opening but no external opening, or although there is an internal opening and an external opening, the middle fistula leads to nasal congestion. The key to treating anal fistula is the internal opening. The existing internal opening resection and drainage devices cannot completely remove the internal opening. [0003] Therefore, an internal orifice resection and drainage devi...
