[0022] The present invention is described in detail below in conjunction with the accompanying drawings. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The present invention provides a push kit for fixing an intrauterine device without surgery under ultrasound guidance, which includes a push outer sleeve 1 that can pass through the cervical canal, and a cervical locator (not shown in the figure) is provided on the push outer sleeve to locate the push outer sleeve at the external cervical os, and the existing cervical locator on the market can be selected; the push kit also includes an intrauterine fixation system 3 connected to an intrauterine contraceptive device 2 and a push rod kit that cooperates with the push outer sleeve, and after the push outer sleeve 1 passes through the cervical canal, the push rod kit pushes the intrauterine fixation system placed in the push outer sleeve to implant the intrauterine bottom wall 4 so that the intrauterine contraceptive device is fixed in the uterus. It can be seen that the push kit of the present invention can achieve the fixation of the intrauterine contraceptive device without the need for hysteroscopic suturing surgery, providing a safer and more acceptable alternative for patients with enlarged uterus and severe dysmenorrhea symptoms who wish to retain their fertility, which not only has lower environmental requirements and improves the convenience of patients, but also reduces the medical burden associated with traditional surgical methods.

[0024] Specifically, the push rod kit includes a needle-shaped push rod 5 and a blunt push rod 6 that can be placed in the push outer sleeve. After the intrauterine fixation system and the intrauterine contraceptive device are placed in the push outer sleeve, the needle-shaped push rod can push the intrauterine fixation system to be implanted in the uterine bottom wall, and the blunt push rod can push the intrauterine contraceptive device into the uterus, thereby achieving the fixation of the intrauterine contraceptive device through the push rod kit. Preferably, the needle-shaped push rod 5 includes a needle rod 51, an intermediate rod 52 and a threading handle 53 connected in sequence, and the intrauterine fixation system 3 includes a copper indicator strip 31 and a resistance knot coil 32 connected to one end of the copper indicator strip, and the other end of the copper indicator strip is connected and fixed to the intrauterine contraceptive device through a connecting line 7. The copper indicator strip is easy to identify, and the connecting line and the resistance knot coil use polypropylene non-absorbable sutures. The resistance knot coil is tied into a knot through the suture to increase friction, so as to ensure that the intrauterine fixation system is not easy to fall off; at the same time, the resistance knot is wound into a coil to push the intrauterine fixation system. During the implementation process, after the needle tip of the needle rod penetrates the coil of the resistance knot coil, the needle tip is pushed into the bottom wall of the uterus by pushing the threading handle, thereby implanting the resistance knot coil into the bottom wall of the uterus.

[0025] The threading handle 53 of the present invention is provided with a thread hole 54, and the connecting line 7 includes a binding belt 71 and a tail wire 72 respectively connected to the other end of the copper indicator strip, the binding belt is tied and connected to the intrauterine contraceptive device, and the tail wire can pass through the thread hole so that the tail wire can pass out of the uterus. On the one hand, it can avoid the connection line blocking the push rod during the pushing process, and on the other hand, it is convenient to take out the intrauterine contraceptive device through the tail wire outside the uterus. Preferably, the blunt-headed push rod 6 includes a blunt-headed rod 61 at the front end and a push handle 62 at the rear end. The blunt head of the blunt-headed rod contacts and can push the intrauterine contraceptive device through the push handle, which not only ensures smooth pushing, but also avoids damaging the intrauterine contraceptive device. The blunt-headed push rod not only has a pushing function but also has a function of detecting the depth of the uterus, and a scale is provided on the blunt-headed rod to more accurately detect the depth of the uterus, which is convenient for medical staff to operate.

[0026] The present invention also provides a method for using the above-mentioned ultrasound-guided non-surgical fixed contraceptive device push kit, which comprises the following steps: First, the intrauterine contraceptive device is fixed with the binding belt of the intrauterine fixation system to connect the two together; then the needle tip of the needle-shaped push rod is passed through the coil of the resistance knot coil, and the tail wire is passed through the wire hole of the threading handle to ensure that the tail wire can be located outside the uterus.

[0027] Next, the assembled needle-shaped push rod is placed into the outer push tube, and the intrauterine fixation system is implanted into the uterine bottom wall by pushing the needle-shaped push rod; then the needle-shaped push rod is withdrawn from the outer push tube, and the intrauterine contraceptive device is pushed from the outer push tube into the uterus by the blunt push rod, thereby achieving the fixation of the intrauterine contraceptive device. When pushing the intrauterine contraceptive device, the specific operation process is as follows: Under ultrasound guidance, the uterine depth is first detected with a blunt-tipped push rod, the depth of which is indicated by the scale mark on the blunt-tipped rod; then the outer push tube is passed through the cervical canal, and the top of the outer push tube is brought into contact with the bottom wall of the uterus according to the detected uterine depth, and then the cervical locator of the outer push tube is used to locate the position of the outer cervical os to ensure that the position of the outer push tube is fixed; then the assembled needle-shaped push rod is placed in the outer push tube, and the needle tip is driven by pushing the threading handle to implant the resistance knot loop into the bottom wall of the uterus, and then the outer push tube is kept fixed, and the threading handle is pulled to withdraw the needle-shaped push rod, and the tail wire is thus released from the thread hole; then the tail wire is pulled to avoid interference, and then the blunt-tipped push rod is placed in the outer push tube, and the push handle is pushed to drive the blunt-tipped rod to push the intrauterine contraceptive device from the outer push tube to the uterus, and at this time, the tail end of the tail wire is still retained outside the uterus, and finally the blunt-tipped push rod and the outer push tube are withdrawn to complete the fixation of the intrauterine contraceptive device. Thus, the present invention is performed only under ultrasound guidance, without the need for hysteroscopic suturing, and provides a safer, more acceptable, minimally invasive and efficient alternative for patients with a history of LNG-IUS device prolapse.
