Problems solved by technology

First, the model and size of the IUD are relatively fixed, but the shape and size of the uterine cavity vary greatly among individuals. It is still impossible to accurately measure the shape and size of the uterine cavity clinically, resulting in the difference between the currently placed IUD and the uterine cavity. Poor fit, causing the IUD to shift and fall off, resulting in placement failure
The second is that most of the IUDs are made of hard materials such as stainless steel and plastic, which have poor deformability and cannot adapt to the changes in contraction and contraction of the uterus. Subject suffers pain and bodily damage

Embodiment Construction

[0009] Such as figure 1 As shown, the present invention provides an IUD adaptable to various uterine cavities, the main body of which is made of nickel-titanium memory alloy wire, stainless steel wire, metal copper wire, medicine and soft elastic materials such as silicone rubber and other traditional materials. Its main body shape is two longitudinal arms 1 and two cross arms 2. The lower ends of the two longitudinal arms 1 are connected in a "U" shape, and the upper ends of the two longitudinal arms 1 are respectively connected to the left and right sides with the two cross arms 2. The two ends of each transverse arm 2 are designed as ends 3 with a tooth-like structure made of soft elastic material.

[0010] Such as figure 2 As shown, the present invention provides an IUD adaptable to a variety of uterine cavities, which exhibits shape 4 in a normal state, and deforms in shape 5 when the cross arm is stressed. The cross-arm width of shape 5 is significantly smaller than ...

Abstract

The invention provides an intrauterine device adaptive to various uterine cavities. A body is made of traditional materials such as nickel titanium memory alloy wires, stainless steel wires, metal copper wires, medicine and soft elastic materials like silicone rubber. According to the shape of the body, two longitudinal arms and two horizontal arms are included, the lower ends of the two longitudinal arms are connected in a U shape, the upper ends of the two longitudinal arms are connected with the two horizontal arms to the left side and the right side respectively, and the two ends of the two horizontal arms are designed to be end heads which are made of the soft elastic materials and are of a tooth-shaped structure. According to the design, the suitability of the intrauterine device and a uterine cavity is increased, and intrauterine device displacement and falling off can be effectively avoided.

Description

technical field [0001] The invention relates to a medical device, in particular to an intrauterine contraceptive device adapted to various uterine cavities. Background technique [0002] There are many shapes and types of IUDs currently in use, and although they all have a certain contraceptive effect, there are still the following two problems that have not been resolved in the actual use process. First, the model and size of the IUD are relatively fixed, but the shape and size of the uterine cavity vary greatly among individuals. It is still impossible to accurately measure the shape and size of the uterine cavity clinically, resulting in the difference between the currently placed IUD and the uterine cavity. Poor fit, causing the IUD to shift and fall off, resulting in placement failure. The second is that most of the IUDs are made of hard materials such as stainless steel and plastic, which have poor deformability and cannot adapt to the changes in contraction and contr...
