The disposable endometrium sampling brush is usually used for stretching the brush hair into the uterus to a certain depth during examination, scraping mucosa fragments on the uterine wall for sampling, and detecting by a professional technical means to determine whether lesions exist. Referring to fig. 1, the female's intrauterine space is divided into an upper uterine cavity 101 and a lower cervical 102, and an endometrial sampling brush is to brush a sample on the inner wall of the uterine cavity 101.

Referring to fig. 2, the prior art endometrium sampling brush comprises a connecting rod 203, a bristle, a limiting ball 201, a protecting tube 202 and a handle 204, wherein the bristle is arranged on a section of the top of the connecting rod 203. When the uterine endometrium sampling brush is used, the protection tube 202 is firstly abutted with the limiting ball 201, then one section of the top of the uterine endometrium sampling brush is stretched into the uterine cavity, and then the protection tube 202 is pulled down to be abutted with the handle 204, so that the brush head is positioned outside the protection tube 202 for rotary sampling, and after sampling, the protection tube 202 is pushed upwards again, so that the protection tube 202 is abutted with the limiting ball 201, and samples on the brush head are protected and sealed. However, women of different regions and ages have different uterine depths, i.e. the depth to which the endometrial sampling brush is required to extend into the uterus of different women is different when taking a sample.

When the protecting tube 202 is abutted against the handle 204, a section of the protecting tube 202 needs to be kept in the cervix 102, if the distance of the protecting tube 202 is too long, the protecting tube 202 is completely withdrawn from the cervix 102, and when the protecting tube 202 is pushed again after sampling, the protecting tube 202 is extruded to the inner wall of the cervix 102, so that a testee feels uncomfortable; if the distance the protective tube 202 is withdrawn is short, the bristles may not be completely detached from the shielding of the protective tube 202, affecting the sampling. However, when the protection tube 202 is abutted against the limit ball 201, the distance between the bottom end of the protection tube 202 and the handle 204 is fixed, so that the distance by which the protection tube 202 is withdrawn is always fixed regardless of the depth of the penetration of the endometrium sampling brush into the uterus. The length of protective tube 202 remaining within cervix 102 is the difference between the depth to which the endometrial sampling brush extends and the distance from which protective tube 202 exits. The prior art endometrial sampling brush has a fixed withdrawal distance of the protective tube 202, and when the endometrial sampling brush is extended into the uterus of different depths, the protective tube 202 cannot be withdrawn to a reasonable position.
