Induced abortion rotary scraping device

Abstract

The invention relates to an induced abortion rotary scraping device. The induced abortion rotary scraping device solves the defects of pain, uterine perforation, abdominal visceral injury and leakage suck in an existing negative pressure abortion surgery when the surgery is conducted. The induced abortion rotary scraping device comprises a pipe body stretching into a uterus, the tail end of the pipe body is provided with a handle, the front end of the pipe body is provided with a foldable rotary scraping body which is made of nickel-titanium-shaped memory alloy, the rotary scraping body is defined by a plurality of axial scraping pieces, the front ends of the scraping pieces are mutually connected into a whole, the rear ends of the scraping pieces are connected to the front end of the pipe body, the edges of the scraping pieces are scraping blades, the scraping pieces are folded to be in a pipe shape, and the scraping pieces are unfolded to be in an inverted pear shape which is matched with the shape of a uterine cavity. The nickel-titanium-shaped memory alloy maintains the pipe shape at normal temperature; when the rotary scraping body enters the human body, the scraping pieces are unfolded to be in the inverted pear shape due to the viscera temperature of the human body, the rotary scraping body is rotated, the scraping blades cut the inner wall of the uterine cavity, less pain exists, and uterine perforation, abdominal visceral injury and other complications are avoided.

Description

technical field [0001] The invention relates to an artificial abortion operation tool, in particular to an artificial abortion rotary scraper which extends into the uterus and expands evenly to match the shape of the inner wall of the uterus. Background technique [0002] At present, abortion or drug termination is often used in the 3 months of pregnancy in the world. Abortion is used as a remedy for contraceptive failure and unwanted pregnancy. It is also used for the prevention of congenital deformities or genetic diseases. Those who need to terminate the pregnancy. Abortion can be divided into surgical abortion and medical abortion in two ways. The commonly used methods are negative pressure suction induced abortion, forceps curettage induced abortion and medical abortion. [0003] Negative pressure suction abortion has been used in my country for more than half a century since 1958, and has played an indelible role in family planning and unwanted pregnancy in my countr...

AI Technical Summary

Problems solved by technology

[0005] Because uterine smooth muscle is sensitive to stretching, it will cause pain, but it is not sensitive to cutting and will not cause pain. The present invention solves the pain during the operation of the existing negative pressure artificial abortion by cutting, and the shape of the cutter is consistent with the shape of the uterine cavity. Cutting avoids the defects of uterine perforation, abdominal visceral damage, and suction leakage in the past, and provides a rotary scraper for artificial abortion. The end of the tube body is connected with a rotary scraper surrounded by scrapers or a ribbed balloon rotary Scraping body, the scraping blade can be stretched when it is heated, and will return to its original shape when it is cold. The air bag can be stretched when it is inflated, and it can be retracted when it is deflated, adapting to the shape of the pregnant uterus, without pain, uterine perforation, suction leakage, and internal organ damage. and other complications

[0006] The present invention also solves the problem that the existing negative pressure artificial abortion uses a rod-shaped suction tube to peel off the pregnancy with the edge of the suction window, which is prone to the defects of unclean peeling, and easily causes complications such as secondary infertility and endometriosis , the present invention provides a rotary scraper for artificial abortion. The end of the tube body is connected with a rotary scraper body surrounded by scrapers. The scraper is heated and stretched to form an inverted pear-shaped structure with an inner cavity. The cutting does not cause pain. The instrument is consistent with the uterine cavity, the curettage is clean, and there are few complications
