According to the measured depth and inclination of the uterine cavity, select the appropriate IUD; adjust the curvature of the placer and the position of the positioning block. Insert the midpoint of the upper edge of the IUD into the placement fork.Make the plane of the IUD parallel to the uterine cavity, gently send the IUD to the fundus of the uterus, fix the outer tube, and advance the push rod about 2mm, the IUD can be protruded from the fork and placed into the uterine cavity.Finally, exit the placer and the operation is complete.

      1. The main body of Yuangong Copper 270 is made of high-quality stainless steel wire, which has the advantages of good compatibility with the human body, moderate elasticity, corrosion resistance, and anti-aging. It can be effectively placed in the human body for more than 10 years. The copper wire is placed The stainless steel wire spiral tube ensures a constant copper ion dissolution rate and avoids local excessive stimulation caused by direct contact between the metal copper and the endometrium. (Stainless steel wire is the same material as the original metal single ring. According to clinical experience and literature reports by experts such as Zhuang Liuqi and Han Xiangyang, it can be placed in the human body for more than 20 years. Silicone rubber is a material for artificial heart valves, which is not easy to age. It can be placed for a long time. According to the ISO7439 international standard, the copper area should be greater than 200mm2, less than 380mm2, and the diameter of the copper wire should be greater than 0.25mm. The dissolution rate of metallic copper is 28.4-31.3μg/d. According to the calculation of the dissolution rate, the Yuangong IUD loaded The diameter of the copper wire is 0.32-0.37mm and can be released for 21.1 years. Yuangong IUD is made of the above three materials, and its service life can be set as 10 years.)


       2. The anti-arc structure and smooth end angle of the upper edge of Yuan Gong Copper 270 are compatible with the fundus and uterine horns. The semi-circular arc shape of the lower edge forms two supporting points with the uterine body. When the uterus contracts, The spiral tube at the upper edge is elastically deformed, and the two end horns move towards the uterine horns; when squeezed, the semicircular arc shape of the lower edge moves in the direction of the center of the circle, that is, the direction of the fundus of the uterus. Therefore, the physics of Yuangong IUD The shape conforms to the uterine morphology and uterine dynamics principle, which can effectively reduce the shedding rate and side effects.


       3. Yuangong copper type 270 increases the copper area and reduces the pregnancy rate with the device.


       4. The placer of Yuangong Copper 270, the concave fork of the fork head is tightly fitted with the IUD, which can automatically lock the IUD, and the IUD will not slip off or shift during the placement process, ensuring that the IUD is accurately placed in place. The placement device has good plasticity, and the curvature of the placement device can be adjusted according to the inclination of the uterus. The diameter of the placement device is only 3.8mm, and the cervix is generally not required to be expanded during placement. Its structure is reasonable and the operation is simple, which is suitable for popularization and application at the grassroots level.
