The front end of the original disposable anorectal hemorrhoid stapler used in the operation is integrated and inseparable, and there is no pocket hole at the front end to adjust the amount of resected tissue. The steps are cumbersome and lengthen the operation time

[0003] The current disposable anorectal cutting stapler is directly fixed and connected with the adjusting bolt, which is inconvenient to use. The current disposable anorectal cutting stapler adopts a straight-grip trial fixed handle, which is very inconvenient to use, and it is easy for the surgeon to operate during the operation. The pinched hand affects the normal operation of the operation, affects the quality of the operation, and brings unnecessary pain to the patient
