Biodegradable material uterine cavity-intracervical contraceptive device and its placement device

Abstract

A novel biodegradable material uterine cavity-intracervical contraceptive device and its placement device, including a placer, the placer includes a cylinder, the front end of the cylinder is provided with a hemispherical end face, and the front end of the side wall of the cylinder is provided with an accommodation cavity. The arc-shaped sliding cover is installed on the side, and the two sides of the arc-shaped sliding cover are provided with protrusions. The guide grooves are arranged on the cylinders on both sides of the arc-shaped sliding cover. The protrusions cooperate with the guide grooves so that the arc-shaped sliding cover can move Sliding along the length direction, the arc-shaped sliding cover can cover the accommodating cavity. Some components of its IUD are made of degradable materials in the human body, which are safe, effective and have less adverse reactions. The matching device can push the IUD from the side to the side of the uterine fundus, which is naturally formed near the opening of the fallopian tube. In the space, avoid the hard contact with the uterine wall during the push-out process of the IUD and damage the uterine wall.

Description

technical field [0001] The invention relates to a contraceptive device and its placement device, more precisely, a biodegradable material uterine cavity-intracervical contraceptive device and its placement device. Background technique [0002] So far, my country has introduced and promoted intrauterine device IUD for 40 years, which has played an extremely important role in controlling the population of our country. Among the currently clinically used contraceptive methods for women, the usage rate of the intrauterine device (IUD) is as high as 50%, and it is widely used because of its advantages of being effective, safe, reversible, convenient, and long-acting. However, most of the currently used IUDs contain bare copper structures. Due to the explosive release (excessive release) of copper ions in bare copper at the initial stage of IUD placement, it is the most important cause of abnormal uterine bleeding, pain and irregular menstruation after IUD placement. In addition...

Problems solved by technology

In addition, the existing IUD placement devices all push the IUD into the uterine cavity at the end of the placer. If the operator does not operate properly during placement, the end of the placer is too close to the uterine wall, and the IUD will be pressed against the uterine wall when the IUD is released. Causes damage, can cause serious adverse effects after surgery
