Description

Technical Field

[0001] This utility model relates to the field of IUD removal equipment technology, specifically an intrauterine IUD removal device. Background Technology

[0002] An intrauterine device (IUD) is a contraceptive device placed inside the uterine cavity. Because early IUDs were mostly ring-shaped, they are commonly called IUDs, also known as intrauterine devices, or simply IUDs. They are typically made of materials such as stainless steel, plastic, or silicone rubber. IUDs without added medication are called inert IUDs. If progestin or copper is added to an IUD, its contraceptive effect can be improved; these are called medicated or active IUDs, and are one of the most commonly used types of contraceptive devices in my country. There are many types of IUDs; commonly used ones in China include single metal rings, spiral rings, mixed rings, IUDs, and T-shaped rings. They have advantages such as safety, effectiveness, economy, convenience, and no impact on fertility after removal.

[0003] An existing patent application (application number 202323524551.1) describes an intrauterine IUD retrieval device, including an expansion plate. A portable component allows for easy carrying via a hand strap, increasing convenience and preventing direct hand contact with the expansion plate surface, thus improving hygiene and effectiveness. The sliding plate and retrieval assembly allow for easy manipulation of the device by pushing it forward with tweezers; the fixed plate moves with the sliding plate, enabling precise tweezer removal of the IUD. The retrieval assembly also facilitates easy replacement, further enhancing the device's effectiveness. However, using rigid support for IUD removal can damage the vaginal cavity wall, compromising safety. Utility Model Content
