Description

Perianal flushing auxiliary device for colorectal and anal surgery

Technical Field

The invention belongs to the field of medical instruments, and particularly relates to a perianal flushing auxiliary device for colorectal and anal surgery.

Background

Anorectal disease refers to a disease that occurs in the anal and large bowel locations, with the largest occurrence in the anorectal bowel segment. The common diseases of the anus include hemorrhoids, anal fissure, anal fistula, perianal abscess, anal papilloma, anal cryptitis, suppurative hidrosis, anal stenosis, anal incontinence, anal condyloma, anal eczema, anal pruritus, perianal neurodermatitis, anal contact dermatitis, anal whitening spots, anal tinea, anal atresia, anal canal inflammation, puborectal syndrome, sacrococcygeal teratoma, benign and malignant tumors of the anus, anal skin defect, anorectal fistula, enterobiasis, rectal cancer, rectal carcinoma, rectal polyp, rectocele, procident, proctitis (ulcer, radioactivity, gonococcal, non-specific, etc.), Crohn's disease, rectovaginal fistula, intrarectal intussusception, anorectal injury and foreign body, fecal impaction, anorectal neurosis, solitary ulcer syndrome, etc.

While anal cleansing is an effective way to treat anorectal diseases, there are two methods of anal cleansing, one is scrubbing and the other is fumigation. The anus scrubbing is to lightly scrub the anus and surrounding tissues by dipping gauze in water, remove dirt on the anus and clean a wound or an operation incision on the anus. The anal fumigation means that the anus and the perineum are fumigated by hot steam, the secretion of the anus is eliminated, and the edema is reduced.

However, the anus is cleaned manually at present, and the patient can not clean the anus completely due to the fact that the anus is cleaned difficultly and cannot be cleaned continuously, and the corresponding treatment effect cannot be achieved.
