Description

Technical Field

[0001] The utility model relates to the field of uterine sampling, in particular to an endometrial sampler. Background Art

[0002] Uterine cancer, also known as endometrial cancer or uterine cancer, is a common cancer in the female reproductive system. In order to detect it early, regular examinations are required. During the examination, the bristles of a disposable endometrial sampling brush are usually inserted into the uterus to a certain depth, and the mucosal fragments on the uterine wall are scraped for sampling. Then, professional technical means are used to test and determine whether there is a lesion.

[0003] For example, the endometrial sampler published in patent application No. 202122719852.4, the endometrial sampler of the utility model has a core rod provided with a brush section, the cross-section of the brush section is trapezoidal, and the protruding length of the bristles relative to the core rod decreases from the second end of the core rod to the first end, that is, when the endometrial sampler of the utility model is used to take samples, the length of the bristles gradually increases from the cervical ostium to the deep part of the uterus, and the overall shape of the brush section is basically the same as the shape of the uterine cavity. In this way, during sampling, the contact area between the bristles of the brush section and the wall of the uterine cavity is larger, and the bristles of the brush section can basically contact the wall of the entire uterine cavity and the tissue fluid in the cavity, so the sampling coverage area is increased, and the obtained samples are more representative, thereby effectively avoiding the phenomenon of unprepared test results due to incomplete sampling, and ensuring that the test results are more accurate.

[0004] The above disadvantages:

[0005] The length of the above-mentioned endometrial sampler is fixed. However, the depth of the uterine cavity of women in different regions and ages is different, that is, the depth to which the endometrial sampling brush is required to be inserted into the uterus of different women during sampling is also different. Therefore, it is necessary to design an endometrial sampler to solve this problem. Utility Model Content
