Description

Technical Field

[0001] The present application relates to the field of anorectal staplers, and in particular, to an anorectal stapler with an adjustment function. Background Art

[0002] A stapler is a medical device that replaces manual suturing. Its main working principle is to use titanium nails to separate or staple tissues, similar to a stapler. Anorectal refers to the anus and rectum. Surgery for some anorectal diseases (such as hemorrhoids) is generally performed with a stapler. The length of a traditional anorectal stapler is fixed, and the length of its tail cannot be adjusted. During the operation, due to the patient's obesity and other reasons, after the top of the anorectal stapler is inserted into the patient's anorectum, the tail end of the anorectal stapler will be closer to the patient's buttocks, which makes it inconvenient for medical staff to operate the anorectal stapler. Utility Model Content
