Cervical canal inner membrane and tissue substance scratching and collecting device

Abstract

The invention discloses a cervical canal inner membrane and tissue substance scratching and collecting device, and the device comprises an operating rod, wherein a curettage head is arranged at the top end of the operating rod, and a first protrusion is arranged in the middle of the operating rod; a sliding block which is coaxially arranged on the operating rod and located below the first protrusion, wherein the sliding block is matched with the first protrusion; and scratching strips, wherein the two ends of each scratching strip are connected with the curettage head and the sliding block respectively, and the number of the curettage strips is not less than two. The device is simple in structure, easy to operate, low in cost, free of harm to human organs and suitable for being used in diagnosis and examination of women of various age groups.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for scraping and collecting endocervical endometrium and tissues. Background technique [0002] Cervical canal scraping usually refers to scraping into the cervical canal with a special small curette, repeatedly scraping the endometrium and tissue of the cervical canal, and taking out the cervical canal tissue for pathological examination to confirm the diagnosis. It is a commonly used diagnostic method in gynecology . For example, when colposcopy is performed on the cervix, the tissue on the surface of the cervix needs to be biopsied, and at the same time, a circular curettage of the cervical canal is sent for pathological examination to rule out cervical cancer and cervical precancerous lesions. The biopsy and scraping pathological diagnosis under colposcopy are also the gold standard and recognized means of cervical disease examination. [0003] In the prior...

Problems solved by technology

[0003] In the prior art, curettage is often performed with a curette. This method is more traditional and has been used until now. In the scraping and scraping process, it may be encountered that the cervical opening is not smooth, there is more cervical mucus or too much blood clots will affect the scraping tissue. In the process of operation, repeated scratching or excessive force will cause strong vagal reflex, resulting in slow heart rate, profuse sweating, severe and even coma, cardiac arrest, clinically known as "vagal response syndrome". At the same time, it may also damage the normal tissue of the cervical canal and cause cervical canal adhesion. For postmenopausal women or patients after cervical LEEP surgery, cervical atrophy and scar contracture, it is usually difficult to enter with a curette, and additional uterine dilatation is required. Only when the uterus is gradually dilated can the curette be sent into the cervical canal for sexual intercourse, which has caused many troubles for the operator. For example, in patients with endocervical atrophy, repeated scraping sometimes fails to scrape the tissues, and there are few tissues Specimens cannot be made into slices, which brings troubles to diagnosis
