Description

technical field [0001] The invention relates to a firing driving device of a disposable anorectal selective cutting stapler, which is used in conjunction with the disposable anorectal selective cutting stapler, belongs to medical equipment, and is especially suitable for anorectal hemorrhoid cutting and anastomosis. Background technique [0002] Anorectal hemorrhoids, commonly known as hemorrhoids, are common and frequently-occurring diseases unique to humans. According to relevant census data, the incidence rate of anorectal diseases is 59.1%, and hemorrhoids account for 87.25% of all anorectal diseases, and among them, internal hemorrhoids are the most common, accounting for 52.19% of all anorectal diseases. Both men and women can get the disease, the incidence rate of women is 67%, and the incidence rate of men is 53.9%. It can occur at any age, and it will gradually increase with age, so there is a saying of "nine hemorrhoids out of ten". General surgical treatment incl...

AI Technical Summary

Problems solved by technology

The operation is troublesome, and the doctor's clinical experience is required during the operation. A little carelessness in the operation will cause excessive bleeding, increase the pain of the patient, prolong the operation time, the success rate of the operation is low, the incision is not smooth and smooth, and the wound suture is not beautiful.

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 one-time anorectal cutting and stapler (PPH) surgical method is stapler hemorrhoidectomy. During the operation, the entire anorectal tissue is resected and anastomosed together, resulting in the cutting off of the superior rectal artery supplying hemorrhoids. Decreased tissue blood supply, long postoperative recovery time
