Technical Field

[0001] The invention relates to the technical field of obstetrics and gynecology, and in particular to an intrauterine ring remover for obstetrics and gynecology. Background Art

[0002] The IUD is a safe and simple contraceptive method. It is relatively safe and effective. The IUD can be placed in the uterus for 5 to 7 years. After the ring is placed, if there are obvious discomfort symptoms, the ring needs to be removed or replaced, or the ring can be removed when planning to become pregnant. Therefore, the IUD needs to be removed from the uterus using an IUD removal device. The process of removing the IUD is: preoperative examination, confirmation of the position of the IUD, and removal of the IUD.

[0003] The prior art IUD removers include: first, a simple IUD remover with a hook at the end, which has a simple structure and is easy to operate. However, due to the limitations of the open hook during use, the ring is prone to fall off, requiring re-operation, which affects the efficiency of the operation and increases the risk; second, the IUD is clamped by designing a front-end opening and closing clamping structure, such as a pliers clamp, but the overall structure is relatively complex, and its large size is not conducive to observation during removal of the IUD, and the overall operation is inconvenient. In addition, due to the limitations of the cervix, the IUD is relatively inconvenient to remove and easily causes pain to the patient, requiring re-operation, resulting in reduced surgical efficiency.
