Abstract

The invention provides a nail-head component of a hemorrhoid anastomat, which at least comprises a nail tube and a nail anvil, wherein the nail tube comprises a housing; the rear end of the housing is used for connecting a hemorrhoid anastomat body; a rise stopping tube is arranged in the housing; the nail anvil comprises a nail anvil ring and a nail anvil shaft which are fixed and connected to each other; the through-hole of the rise stopping tube comprises at least two planes arranged along the axis of the rise stopping tube; guide grooves are respectively arranged on the planes; and at least two planes are correspondingly arranged on the nail anvil shaft, and guide ribs are respectively arranged on the planes in a way that the guide ribs can slide in the guide groove. The invention has the following beneficial effects that: by arranging two symmetrical guide ribs, the nail anvil shaft and the rise stopping tube are in finer fit, thereby ensuring the fit of the nail tube and the nail anvil and further ensuring the effect of anastomosis.

Description

technical field [0001] The invention relates to a hemorrhoid stapler, in particular to a nail head assembly of the hemorrhoid stapler, and belongs to the technical field of medical instruments. Background technique [0002] People have known about hemorrhoids for more than 4,000 years. The traditional methods of internal hemorrhoid treatment include sclerosing agent injection, rubber band ligation and various forms of surgical resection. These methods all treat the hemorrhoid itself, aiming at shrinking or disappearing the hemorrhoid. Among the surgical procedures for hemorrhoidectomy, there is a method called PPH surgery, which is suprahemorrhoidal circumcision with the help of a hemorrhoid stapler. [0003] U.S. Patent No. 6,083,241 discloses a hemorrhoid stapler. Its nail head assembly includes an anvil and a nail barrel. A nail bin, a nail pusher, and a nail are arranged in the nail barrel. The anvil and the nail barrel face each other. The mucosa on the hemorrhoid is ...
