Description

Technical Field

[0001] The utility model relates to the technical field of contraceptive devices, in particular to a contraceptive device pusher. Background Art

[0002] The IUD is a clinically recommended, highly effective, long-acting, and reversible contraceptive tool. It generally includes hormone-releasing IUDs and copper IUDs. Hormone-releasing IUDs release hormones to inhibit ovulation and endometrial growth. In addition to contraception, they can also treat some gynecological diseases. Copper IUDs prevent sperm from combining with eggs and prevent fertilized eggs from implanting by releasing copper ions. They are usually placed by doctors in professional medical institutions and are effective for 5-10 years.

[0003] The method of using the IUD in the prior art is: after measuring the depth of the uterine cavity, move the white positioning block on the preventer to the corresponding position, put the preventer into the uterine cavity along the direction of the uterine cavity, fix the transparent outer placement rod, pull out the white inner push rod, and then take out the preventer. Its disadvantages are that the pusher has no curvature, poor elasticity, and is overall thicker. If the internal cervical os is tight or the curvature of the uterus is large, it cannot be inserted into the uterine cavity, which increases the difficulty of placing the ring and even causes failure. The IUD and the push rod are connected by a groove, and the fixation is poor, which can easily cause the IUD to be placed improperly or even fall off. This pusher is not universal and is only suitable for metal rings. Utility Model Content

[0006] Preferably, a push-driving screw is rotatably inserted into the side surface of the positioning seat, and the push-driving screw and the movable connecting seat are penetrated by a threaded structure.

[0007] Preferably, the pushing drive screw is arranged relatively parallel to the pushing rod in the inner area of ​​the positioning seat, and a screw driving motor is installed at the other end of the pushing drive screw through a coupling.

[0008] Preferably, the main sleeve and the handle fixed shell are commonly connected to a handle movable shell, the screw drive motor is located between the positioning seat and the handle movable shell, a control key is installed on the side of the handle movable shell, and the control key is electrically connected to the screw drive motor through a motor driver.

[0009] Preferably, the screw drive motor drives the push drive screw to rotate forward or reversely, thereby driving the movable connecting seat forward or backward, thereby driving the push rod forward or backward.

[0010] Preferably, the cross-sectional dimension of the main sleeve is larger than that of the rubber tube, and an integral handle fixing shell is provided on the side of the main sleeve, and the handle fixing shell and the main sleeve form an L-shaped structure.

[0011] Preferably, the rubber tube and the IUD positioning sleeve are made of transparent material.

[0012] Preferably, the rubber tube and the push rod are both bendable structures.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the IUD pusher relatively connects the IUD positioning sleeve and the main sleeve through a bendable transparent rubber tube to form a detachable structure, and the rubber tube and the IUD positioning sleeve can be replaced and freely combined, thereby reducing the types of pushers and unnecessary material waste. When the IUD pusher is in use, the transparent rubber tube is sealed and clamped at the end of the main sleeve, making it easy to replace the rubber tube. At the same time, the IUD positioning sleeve is covered by the rubber tube to play a protective role. The IUD positioning sleeve can be replaced according to the type of IUD, making it easy to use the pusher. BRIEF DESCRIPTION OF THE DRAWINGS
