Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a hemorrhoid stapler capable of purse-string suture-free and a kit containing the hemorrhoid stapler. Background technique [0002] Anal hemorrhoid disease is a common anorectal disease with many patients. When the anal cushion is loose and hypertrophic, bleeding or prolapse, the symptoms of hemorrhoids will occur. According to the location of hemorrhoids, anal hemorrhoids are divided into three types: internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids, all of which have the characteristics of recurrent attacks and cause a lot of inconvenience to people's daily life. [0003] Suprahemorrhoidal circumcision (PPH) with hemorrhoidal stapler is currently a mature surgical procedure in anorectal surgery, which is widely used clinically and has definite curative effect. The operation modes of various hemorrhoid staplers are basically the same. Du...

AI Technical Summary

Problems solved by technology

[0004] Therefore, at present, purse string suture of the rectal mucosa under direct vision cannot be avoided in the circumcision of suprahemorrhoidal mucosa. Both the depth of the suture needle can easily lead to injury, and the different pull-in force will lead to an unstable range of mucosal resection. For example, when the circular resection deeply hurts the muscular layer Stenosis due to scar contracture

Therefore, when the current hemorrhoidal stapler is used for hemorrhoidal mucosal circumcision, skilled suturing techniques and moderate pulling force are required. Inadvertent operation is prone to submucosal hematoma, uneven resection, muscle layer damage, postoperative bleeding, and complications. Stenosis etc.
