Description

Endometrium sampler under hysteroscope

Technical Field

The invention relates to the field of medical instruments, in particular to a hysteroscope lower intimal sampler.

Background

When the existing infertility patient carries out accurate location biopsy of endometrium, the sampling and sampling device of endometrium adopts biopsy forceps with frame grooves to grab samples for assay, and because the length of the sampled endometrium sample forceps and the sample amount obtained once when the frame grooves are small, the accuracy of the made pathology is not high, the sampling is often repeatedly needed, and the operation time is prolonged. Sometimes, in order to improve pathological accuracy and extract a plurality of sample quantities, medical personnel can take relatively large instruments such as a doctor blade to remove blind scraping and sampling, so that the fixed point for taking materials is inaccurate, the intima is easily excessively injured, and the pain of a patient is severe and the operation risk is high. There are also other endometrial samplers known as a method for sampling endometrium, including samplers and sampling methods, as disclosed in application No. CN 202210558616.5. The sampler is mainly formed by connecting a guide tube, a brush head, a guide shaft and a push rod; the lead shaft is driven by the push rod to pull the brush head to move longitudinally on the surface of the endometrium, and the sampling layer of the brush head rubs and brushes endometrial cells to obtain a diagnosis sample. The device picks up the sample through the brush and relies on the sample to glue and take out on the brush, and this method and sample mode still have the sample and easily lose, and the volume of getting is uncontrollable or too little result. Repeated brushing also easily causes discomfort or excessive specimen collection.
