The front end of the clamp head is an arc-shaped structure to avoid damage to the patient's body tissue during the clamping process;

[0019] An anti-dropping block is embedded inside the clamp head. During the interlaced closing process, the anti-dropping block can increase the friction of the IUD through the long tooth block and the short tooth block to prevent the IUD from falling off. The end faces of the long tooth block and the short tooth block are relatively flat to avoid damage to body tissues.

[0020] The long teeth and short teeth on the left and right sides of the clamp are arranged in a staggered manner. Through the height difference of the staggered arrangement, the IUD can be clamped more stably at the port of the IUD removal clamp.
