Description

Technical Field

[0001] The present invention relates to the technical field of obstetrics and gynecology instruments, and specifically to a multifunctional adjustable intrauterine device remover for obstetrics and gynecology. Background Technique

[0002] An intrauterine device remover is a commonly used medical device in obstetrics and gynecology, mainly used to remove intrauterine devices. Intrauterine devices are a common contraceptive tool, but sometimes they need to be removed due to the patient's physical condition, the service life of the intrauterine device, or the occurrence of complications. Removing the intrauterine device means that when the inserted intrauterine device has reached the specified age limit, it is necessary to go to the hospital in time to remove it to prevent the intrauterine device from deforming or becoming ineffective in the uterus. And different medical devices are required for removing the intrauterine device. In order to remove the intrauterine device from the body, a special intrauterine device hook is needed to determine the position of the intrauterine device and hook it, and then pull it outwards to remove it. The intrauterine device remover is a tool for pulling out the intrauterine device in the uterus.

[0003] However, there are still some deficiencies and areas for improvement in the actual use of existing intrauterine device removers. When using existing intrauterine device removers, the device needs to be inserted into the patient's vagina and uterine cavity. The existing method is to cooperate with a duckbill forceps and gradually adjust the bolt to open the patient's vagina and cervical orifice. This method has low overall efficiency during adjustment and use, and will increase the patient's psychological burden during the adjustment process. At the same time, existing intrauterine device removers cannot adjust the grasping angle according to the required angle during use. The existing method is to manually rotate the entire device by medical staff, which is inconvenient to use. Therefore, technicians in this field have provided a multifunctional adjustable intrauterine device remover for obstetrics and gynecology to solve the problems raised in the above background technique. Summary of the Invention

When in use, the upper expansion plate 401 and the lower expansion plate 402 are inserted into the patient's vagina. Subsequently, by slowly pressing down the adjustment plate 405, the patient's vagina is fully expanded, facilitating subsequent operations. After expansion, by pressing down the dial block 410 and the expansion plate 408, the telescopic rod 406 is stretched, and the expansion plate 408 slides in cooperation with the two limit plates 409 at both ends, while the two limit plates 409 are opened to both sides. When the expansion plate 408 cannot be pressed down any further, the distance between the lower expansion plate 402 and the upper expansion plate 401 is fixed, making the overall adjustment more efficient and the operation more convenient;

[0043] By pushing the grip rod 301 with the rotating rod 315 forward, under the push of the push rod 316, the first spring 311 is stretched, and the two clamping rods 319 are released from the restriction of the inner side walls of the storage groove 309. Under the elastic action of the two second springs 317, the two clamping rods 319 are opened. After grasping, by removing the push on the push rod 316, with the contraction of the first spring 311, the stop rod 310 is retracted into the interior of the storage groove 309, and the two clamping rods 319 are squeezed between the inner side walls of the storage groove 309 and return to their original state, thus clamping and taking out the intrauterine device;

[0044] The grasping angle can be adjusted according to the needs during use. By pulling out the adjustment gear 302 from the interior of the gear groove 314 and stretching the internal stretching rod, the adjustment gear 302 is released from the restriction of the gear groove 314 on its rotation. At this time, the sleeve 313 drives the connecting plate 307 and the front-end structure to rotate and adjust. The adjustment gear 302 can be rotated according to the needs during use to change the direction of the front end. Subsequently, by inserting the adjustment gear 302 back into the interior of the gear groove 314, the adjusted direction is restricted, facilitating use.
