Uterine curettage device for gynecological diagnosis

Abstract

The invention provides a uterine curettage device for gynecological diagnosis, which is applied to the field of uterine curettage diagnosis. The uterine curettage device mainly comprises a vaginal dilatation module and a telescopic curette module. By arranging the telescopic curette module, curettes can be expanded by stretching and retracting to be in contact with tissue cells on the inner wall of the uterine cavity, then the curettes can be rotated by rotating tube bodies to scrape off the tissue cells to serve as detection samples, and operation is easy and convenient; a telescopic tube mechanisms with different outer diameters is arranged, and the cervix uteri is opened by gradually pushing the tube body, so that the tube body is convenient to move and sample; sampling can be performedby rotating the tube bodies, and the phenomenon that a traditional curette needs to be drawn back and forth, so that the inner wall of a uterine cavity and a vagina are prone to being abraded by thetraditional curette, and bleeding occurs after diagnosis and curettage is avoided; and by arranging an outer tube sleeve, the tube bodies can be further isolated from a human body, and abrasion causedby contact between the hard tube bodies and the fragile uterine cavity and vagina is avoided.

Description

technical field [0001] The invention relates to the field of dilatation and curettage diagnosis, in particular to a dilation and curettage device for gynecological diagnosis. Background technique [0002] Curettage refers to the operation of scraping the endometrium or the contents of the uterine cavity. Minor surgery often performed in obstetrics and gynecology is one of the methods of induced abortion. There are two types of dilatation and curettage (referred to as curettage) and therapeutic curettage. Curettage is divided into general curettage and segmental curettage. General diagnosis and curettage, suitable for endocrine abnormalities need to understand the changes of endometrium and the response to sex hormones, whether there is ovulation, whether there is tuberculosis and other diseases. Segmented diagnosis and curettage refers to scraping the cervical canal first and then curettage of the uterine cavity, and sending the scrapings to pathological examination separ...

Problems solved by technology

[0003] Through the feedback from the gynecological medical staff of the existing hospitals, the team learned about the shortcomings of the existing curettage devices, and also visited major hospitals to conduct research on the curettage devices, and after a massive search, found that the existing curettage devices The structure of the device is mainly US4641662A, CN109498129B, CN108210027B and CN103815955B, the comprehensive above diagnosis and curettage device can know that the existing curettage device mainly includes a dilatator and a curettage spoon, wherein the curettage spoon includes an operating rod, a spatula and a handle; The spoon and the handle are respectively arranged at the two ends of the operating rod. The vagina is expanded through the vaginal dilator, and then the spatula is penetrated into the uterine cavity, and then rubbed back and forth after contacting the wall of the uterine cavity. This operation often requires the operation rod and Frequent friction between the vagina and the cervix can easily cause damage to the fragile vagina and cause frequent bleeding in patients after the examination. After resisting the protective effect of external bacteria, it is prone to bacterial infection
