Abstract

The invention discloses an anal hemorrhoid nailing stapler component. The anal hemorrhoid nailing stapler component comprises a C-shaped stapler nail bin, a clamping spring tube, a connecting shaft and a nail supporting seat; and the C-shaped stapler nail bin and the nail supporting seat are detachably installed through the snap spring tube arranged at a central hole of the C-shaped stapler nail bin and a connecting shaft fixed at the circle center of the nail supporting seat in a mode of snap spring fit. When the component is used for rectal mucosa excision operation, cutting anastomosis integrity can be kept, so that elasticity of mucosa tissues at the position can be kept, and postoperative complications such as anastomosis stenosis and the like can be avoided.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a stapler assembly for anal hemorrhoids. Background technique [0002] According to the latest survey results, the incidence of anorectal diseases in my country is increasing year by year, and the current incidence is as high as 59.1%, of which hemorrhoids account for 87.2%. A tissue located between the anal canal and the rectum in the human body is called the anal cushion. The anal cushion is a ring-shaped band of tissue above the dentate line in the anal canal. The ring-shaped tissue band is thick and soft and is a highly specialized blood vessel Sexual liner is a normal tissue of the human body, but due to reasons such as diarrhea, constipation, and increased abdominal pressure, pathological hypertrophy occurs, and it is called hemorrhoids when it moves down. At present, the suprahemorrhoidal mucosal excision and anastomosis (PPH) is used clinically to move the anal cushion...
