Because the occluder is a three-dimensional device, the second plane and the first plane are arranged at an included angle of 90 degrees, the overall outline of the occluder can be more comprehensively displayed, the developing effect is improved, and the situation that the displacement of the occluder in the process of being implanted into a human body affects the developing angle of the first developing wire 20 is avoided. However, it should be noted that the number of the developing wires and the degree of the included angle formed by the winding can be adjusted according to the actual situation.

The above-mentioned manner of withdrawing from the human body by pulling the control end of the developing wire is a preferred embodiment of the present invention, as shown in fig. 3, in one embodiment, the present invention further includes a separately disposed control wire 50, the control wire 50 is disposed outside the supporting body 10, the control wire 50 is connected to the position where the developing wire is threaded around the second end 12 of the supporting body 10, the end of the control wire 50 away from the end connected to the developing wire is an operation end 51, wherein the operation end 51 extends outside the human body, and in order to prevent the control wire 50 from affecting the smooth threading of the developing wire on the stopper, the control wire 50 can be connected to the developing wire after the completion of the disposing of the developing wire. After the release of the occluder is finished, the two ends of the developing wire are simultaneously pulled out from the second end part 12 by pulling the operation end 51 of the control wire 50, so that the speed of detaching the developing wire from the occluder and withdrawing the developing wire from a human body is increased, and the working efficiency is improved.

Because the developing wire made of metal materials is generally high in elastic modulus, hard in material and poor in compliance, the developing wire is difficult to weave on the plugging device in a penetrating and winding mode or withdraw from the plugging device, and deformation of the plugging device can be caused; the developing wire prepared by adopting the high polymer material has lower elastic modulus, is more favorable for the developing wire to be woven on the plugging device in a penetrating and winding way, does not influence the shape and the supporting performance of the main body of the plugging device, can better reflect the real shape of the plugging device and improves the developing effect; meanwhile, the development silk is prevented from possibly damaging the tissue in the withdrawing process due to high elastic modulus, and the human tissue is protected.

The wire body 40 is further coated with a lubricating layer 42, and the lubricating layer 42 covers the surface of the developing layer 41. The arrangement of the lubricating layer 42 reduces the frictional resistance between the developing wire and the supporting body 10, thereby reducing the resistance of the developing wire in the withdrawing process, further ensuring that the human tissue is not damaged, and avoiding causing complications.

In one embodiment, as shown in FIG. 5, a hydrogel material is used for silk body 40 of the development silk, and development particles 43 are contained in silk body 40. The developing silk made of hydrogel material has low elastic modulus and lubricity, can reduce the resistance of the developing silk in the withdrawing process, further ensures that human tissues are not damaged, and avoids complications; meanwhile, the developing particles 43 are added into the hydrogel material, so that the silk main body 40 has a developing function, and the mechanical strength of the silk main body 40 is enhanced.
