Negative pressure endometrium sampler and use method thereof

Abstract

The invention belongs to the field of medical apparatuses, and particularly relates to a negative pressure endometrium sampler and a use method thereof. The negative pressure endometrium sampler comprises a negative pressure adsorption device, a pressure regulating device and a rotatable adsorption tube, wherein the rotatable adsorption tube comprises a rotating sleeve tube and an adsorption tubeassembly, the adsorption tube assembly comprises an adsorption tube and a protecting tube arranged outside the adsorption tube, scrapers and absorbing holes are peripherally distributed at one end away from the rotating sleeve tube, of the adsorption tube, one end of the rotating sleeve tube is connected with the pressure regulating tube, and the inner part of the other end of the rotating sleevetube and the outer wall of the adsorption tube are in cooperation and rotating connection through a bearing; a rotating block is arranged at the connecting end of the adsorption tube and the rotatingsleeve tube; a clamping block in movable connection is arranged between the protecting tube and the rotating block; the rotating block and the protecting tube can perform magnetic suction and adsorption; an end socket is arranged at the top of the adsorption tube; and when the clamping block is mounted, the protecting tube and the end surface of the end socket are in contact and cooperation. The device can remove liquid in a womb before endometrium scraping, so that the endometrium sampling quality can be improved.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a negative pressure endometrium sampler and a using method thereof. Background technique [0002] Some patients with endometrial cancer or suspected endometrial cancer need to extract endometrial samples for pathological examination before diagnosis. At present, when obstetricians and gynecologists do endometrial pathological examination, they mostly use dilatation and curettage. Sampling, metal endometrial curettes are mostly used during curettage, and the scraping head is in the shape of a scoop or spoon. During operation, the endometrial curette is inserted along the direction of the cervix to the bottom of the uterus, and it is close to the uterine wall from the top Then scrape several slices to obtain endometrial specimens. [0003] The existing method of sampling the endometrium using an endometrial curette has the following problems: [0004] 1. When using a ...

AI Technical Summary

Problems solved by technology

[0004] 1. When using a curette, the medical operator needs to use a lot of force. The curette has a greater pressure on the uterine wall, greater damage to the uterine wall, and greater pain for the patient. What is more serious is that if the medical staff does not operate properly, it is easy to cause The patient’s uterus is perforated, causing massive bleeding and life-threatening; 2. The sampling effect of using a curette is poor, and continuous sampling of multiple parts cannot be carried out; 3. When a small amount of liquid is stored in the uterus, if it is not cleared first, the sampling sample will be reduced Quality; while the traditional method is to remove the fluid in the uterus first, and then extract the sample, and this repeated entry into the uterus will bring pain to the sampler, and in severe cases, it will cause external bacteria to enter the uterus and cause infection, so it needs to be designed A new type of negative pressure endometrial sampler to overcome the above-mentioned technical defects
