Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular, relates to an anorectal stapler with a drug-adding treatment function. Background Art

[0002] The tubular anorectal stapler is a disposable surgical instrument suitable for anorectal anastomosis of the human body. Its principle is to retain the anal cushion, perform circular excision and anastomosis of part of the internal hemorrhoids and the mucosa and submucosal tissue above the hemorrhoids, and perform instant anastomosis at the same time, which not only blocks the blood supply of the hemorrhoids, but also suspends and fixes the slipped tissue, and restores the pathological anorectal rectum to a normal anatomical state. The tubular anorectal stapler mainly includes an anvil assembly, a staple cartridge assembly, a fixed handle assembly, an adjusting screw assembly, a pointer mechanism, a movable handle assembly, a push rod assembly, and a safety block assembly. When in use, the anvil of the anvil assembly is connected to the screw of the adjusting screw assembly through the connecting shaft, and the adjusting nut is turned clockwise to cause the screw to drive the connecting shaft to move backward, thereby driving the anvil to move backward. When the anvil and the staple cartridge assembly reach the specified anastomosis distance, the pointer mechanism will be displayed in the safe green zone, the safety block assembly is manually opened, and the movable handle assembly is pulled to fire the push rod assembly. The inner annular knife of the staple cartridge assembly is used to cut excess tissue through the push rod assembly. At the same time, the suture staples in the staple cartridge assembly are pushed out to anastomose the tissue.

[0003] At present, the tubular anorectal stapler can only simply remove the mucosa above the dentate line of the patient's anorectal cavity, which is prone to anorectal mucosal damage, tearing or bleeding, and even anastomotic bleeding. Therefore, during the operation, if the surgical site cannot be treated with medication in time, the patient usually has postoperative adverse phenomena such as pain, edema, and bleeding at the surgical site. In severe cases, it may also cause problems such as postoperative exogenous contamination. Summary of the invention

[0004] The purpose of the embodiments of the present invention is to provide an anorectal stapler with a medication treatment function that can simultaneously perform medication treatment on the surgical site while removing the mucosal tissue on the dentate line of the anorectal rectum, so as to solve the technical problem that the tubular anorectal stapler existing in the prior art can only simply remove the mucosa on the dentate line of the anorectal rectum, but cannot perform medication treatment on the surgical site in a timely manner, resulting in pain, edema, and bleeding at the surgical site of the patient.
