[0002] An endometrial sampler is a device used to extract samples from the endometrium, usually for medical research or diagnosis. The endometrial sampler can obtain different types of samples, such as exfoliated cells, secretions, and cell fragments, by sampling at different stages of the menstrual cycle to better understand the physiological and pathological changes of the endometrium. On the 12th to 14th day of the menstrual cycle, usually 7th to 10th day before the next menstruation, the doctor or nurse can use the endometrial sampler to take a sample from the endometrium and then put it into a special sample collector. The sample can be further analyzed in the laboratory using various reagents to understand the physiological and pathological changes of the endometrium.

[0003] When using the sampler, the outer sleeve is inserted into the sampling position, and the sleeve core is pulled outward to move the piston at one end of the sleeve core, thereby generating negative pressure inside the outer sleeve, and tissue fluid is drawn into the sampling hole at one end of the outer sleeve for sampling. This sampler does not require scraping and has low pain. However, the tip of this sampler is relatively sharp, and there is still a certain pain during the insertion process. Therefore, the utility model proposes a painless endometrial sampler to solve the problems existing in the prior art. Utility Model Content
