Embodiment Construction

[0026] like figure 1 As shown, a rat intrauterine device includes a copper wire part 1, the front end of the copper wire part 1 is connected with a wire loop 2 made of silk thread, and the front end of the wire loop is tied with a wire knot 21; the copper wire part 1 The rear end is connected with a pulling wire 3.

[0027] like figure 2 As shown, a rat intrauterine device placer mainly includes a push core 4 and a rigid external sleeve 5 .

[0028] like image 3 As shown, the head end of the push core 4 is provided with a fork 41 , and the tail end is provided with a handle 42 . The fork 41 is formed by separating the head ends of the two fork legs 411 and connecting the tail ends together. The head ends of the two fork legs 411 are needle-like, as Figure 4 shown.

[0029] like figure 2 As shown, the inner diameter of the rigid outer casing 5 is greater than the width of the widest part formed by the separation of the two prongs 411 and the outer diameter of the push...

Abstract

The invention discloses an intrauterine device for rats, a placer for the intrauterine device and a manufacturing method for noninvasive type contraceptive rat models with the intrauterine device. The intrauterine device comprises a copper wire part, wherein the front end of the copper wire part is connected with a wire ring made of silk threads; and the rear end of the copper wire part is connected with a traction silk thread. The placer comprises a push core, wherein a fork head is arranged at the head end of the push core; a handle is arranged at the tail end of the push core; the fork head is formed by separating head ends of two fork legs and connecting tail ends of the two fork legs; the head end of each fork leg has a needle point shape; the inner diameter of a rigid outer casing is greater than the width of the widest part formed by separating the two fork legs and the outer diameter of the push core; and the length of the rigid outer casing is smaller than that of the push core. According to the preparation method for the rat models, the intrauterine device for the rats and the placer for the intrauterine device are adopted, so that the rats are not required to receive an open surgery, the intrauterine device is placed through the way of cervix-intrauterine, the contraceptive rat models with intrauterine device, which is in accordance with the clinical contraceptive method through the intrauterine device, are prepared; and the manufacturing method is easy and convenient to operate, the risk is low, and the efficiency is high.

Description

technical field [0001] The invention relates to a device for birth control of rats and a simulated placement method of the birth control device, in particular to a rat intrauterine device and its placement device and a method for preparing a non-invasive intrauterine device contraceptive rat model. Background technique [0002] At present, in animal experiments, for the birth control of rats, there is no IUD specially suitable for rats. All of them open the uterine cavity through the abdomen, cut or change the shape of the human IUD, put it into the uterine cavity and suture and fix it on the uterine wall. The surgical procedure is not consistent with clinical IUD placement, and a similar animal model cannot be provided for clinical research. The surgical operation is complicated, the efficiency is low, and the animal mortality rate is high. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the object of the present...
