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

Abstract

The invention relates to an indicating safety device of a disposable anorectal selective cutting anastomat, belongs to the field of medical apparatuses, is used for matching the disposable anorectal selective cutting anastomat for use, and is especially applicable to anorectal hemorrhoid cutting anastomosis. The indicating safety device comprises an observing window, a pointer, a pointer spring, an adjusting block, a guiding screw, a compression spring, a pointer drag hook and a triggering safety lug boss, wherein pointer and the pointer spring are mounted and fixed to a pointer mounting bulge and a pointer spring mounting bulge on a fixing handle respectively; the outer shape of the pointer is U-shaped; a screw rod runs through the pointer; a circular hole is formed in the pointer drag hook and sleeves the screw rod; a drag hook is arranged at the front end of the pointer drag hook and is hooked to the pointer; an avoiding slot is formed in the front end of the pointer drag hook; the observing window is mounted into an observing window mounting hole in the fixing handle; through the observing window, the position of the pointer can be observed; the compression spring sleeves the screw rod at the back end of the pointer drag hook; a long waist-shaped hole is formed in the adjusting block; the adjusting block is fixed to the screw rod through the guiding screw; the long waist-shaped hole can adjust the position of the adjusting block manually.

Description

technical field [0001] The invention relates to an indicating safety device for 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...
