Abstract

The invention provides an anal canal cell sampling device, an introducing expander and an anal canal cell sampling method. The anal canal cell sampling device comprises a first connecting piece, a handle, a sampling part and a limiting assembly, wherein the handle and the sampling part are separately and fixedly connected to two ends of the first connecting piece; the limiting assembly is used forlimiting the extending distance of the sampling part in an anal canal, and is arranged on the first connecting piece in a sliding and sleeving manner; and soft hairs cover the outer surface of the sampling part, are wavy, and are arranged in the radial direction of the sampling part. A patient can independently complete the work of sampling cells on a mucous membrane of the anal canal through a noninvasive screening manner, so that the privacy of the patient can be protected, the patient can conveniently detect early-stage anal canal cancer and precancerous lesion, and the patient can seek medical advice in time, so that the survival rate of the patient is increased; and the whole operation process is simple and convenient.
