Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gynecological medical instruments, namely, an intrauterine contraceptive device placement sleeve and a propeller. Background Art
[0002] In the prior art, there are many types of contraceptive rings, such as the levonorgestrel intrauterine system (trademark: Mirena, commercially available product. hereinafter referred to as Mirena IUD) with a "T" stent structure, in which synthetic progesterone is stored in the longitudinal tube and supported in the uterine cavity. It can release synthetic progesterone, forming a high level of progesterone locally in the uterine cavity, causing changes in the endometrium, which is not conducive to the implantation of the fertilized egg and achieving contraception. At present, in addition to being used for contraception, the Mirena IUD can also be used to treat abnormal uterine bleeding, dysmenorrhea and menorrhagia caused by endometriosis and adenomyosis, postoperative management of endometrial polyps, endometrial proliferative diseases, prolonged menstruation caused by cesarean section diverticulum, and endometrial protection of menopausal hormone therapy. However, the Mirena IUD has a single model, and it is easy to move downward or even fall off after placement in a larger uterus, resulting in economic losses to patients, poor treatment effects, and poor compliance. In order to solve the problem of Mirena IUD falling off, the domestic use of hysteroscopy to sew Mirena IUD to the bottom of the uterine cavity is still cumbersome, with a long learning curve, and it is not easy for beginners to master hysteroscopy. At the same time, it increases the incidence of perioperative complications of hysteroscopic surgery and greatly increases the cost of surgery, which runs counter to the basic concept of health economics. Stentless fixed intrauterine contraceptive device (IN / S type), trademark: Jinni, commercial product, hereinafter referred to as Jinni IUD. The traditional Jinni IUD consists of six copper sleeves 5 arranged in sequence strung together by silk thread 9 (polypropylene silk thread), and the front end of the front copper sleeve has a sharp thorn, a barb thorn 7 and a knot 8. The pusher includes a sleeve 1 with a scale (without a notch), a push rod 2 is inserted into the sleeve 1, the front end of the push rod 2 is fixed with a cone connected to the Jinni IUD, and the rear end of the push rod 2 is connected with a push handle 3. The implant is inserted into the uterine cavity through the self-contained propeller, and the sharp thorns penetrate into the inner wall of the uterine cavity. The barbed thorns 7 make the Jini IUD hang in the upper wall of the uterine cavity (see Figure 3 The pusher includes a sleeve 1 with a scale, a push rod 2 is inserted into the sleeve 1, the front end of the push rod 2 is connected to the Jinni IUD, and the rear end of the push rod 2 is connected to a push handle 3 (see Figure 3 ), insert the sleeve 1 into the uterine cavity, push the push handle 3, push the Jini IUD out of the sleeve 1, insert the front end spikes and barb spikes 7 into the uterine cavity wall, and the Jini IUD is hung in the uterine cavity. The copper ions released by the copper sleeve 5 play a contraceptive role, but it has no therapeutic effect on the above diseases.
[0003] The two intrauterine contraceptive devices each have advantages and disadvantages. If they are placed together, they can complement each other and have a better treatment effect. However, due to the limitation of the thruster, the process of inserting two intrauterine contraceptive devices at the same time will interfere with each other, making them difficult to place. Utility Model Content
[0004] The purpose of the utility model is to provide an intrauterine contraceptive device placement sleeve and thruster that can be conveniently inserted into the uterine cavity after the Genesis IUD and the Mirena IUD are bound together to reduce the probability of the IUD moving downward and falling off, and is easy to insert and has good use effect.
[0005] The technical solution of the utility model is: an intrauterine contraceptive device placement sleeve comprises a sleeve with scales, and is characterized in that the sleeve is provided with a notch along the longitudinal direction.
[0006] Another solution is an intrauterine device pusher, comprising a graduated sleeve, a push rod inserted in the sleeve, a front end of the push rod connected to the Gini IUD, and a rear end of the push rod connected to a push handle, characterized in that the sleeve has a notch in the longitudinal direction. That is, the notch is directly opened in the longitudinal direction on the traditional sleeve, and other structures remain unchanged.
[0007] The notch is 2 mm wide and has a length equal to the length of the sleeve.
[0008] The advantages of the utility model are: 1. The intrauterine contraceptive device placement sleeve adopts a front-opening long notch structure, so that the Mirena IUD and the Gini IUD can be bound together, and the Gini IUD pusher is used to send them into the uterine cavity, so that the two IUDs can be used at the same time. The Mirena IUD is fixed in parallel with the Gini IUD, which reduces the chance of the Mirena IUD moving down and falling off. It is easy to insert and reliable to use, and the use effect is improved. 2. The intrauterine contraceptive device placement sleeve can be provided separately and used in conjunction with the Gini IUD pusher. The sleeve in the Gini IUD pusher can also be replaced with the intrauterine contraceptive device placement sleeve as a pusher replacement product. 3. It is non-destructive to use, and does not require the use of a hysteroscope for intrauterine suture operations, which can effectively reduce treatment costs. 4. After binding the Mirena IUD and the Genie IUD, insert them into the uterine cavity through this device, making full use of the respective advantages of the two intrauterine contraceptive devices, reducing the probability of the IUD moving downward or falling off, so that the Mirena IUD can be worn to its effective service life and achieve better treatment effects. This device can solve the problem that the placement system of the two IUDs cannot efficiently and accurately place the two IUDs at the same time and the probability of secondary damage is high. It does not require the use of hysteroscopy for intrauterine suture operations, which can effectively reduce the economic cost of treatment. 5. The two IUDs can be used at the same time, which can be applied to abnormal uterine bleeding in a larger uterine cavity, dysmenorrhea and menorrhagia caused by endometriosis and adenomyosis, postoperative management of endometrial polyps, endometrial proliferative diseases, prolonged menstruation caused by cesarean section diverticulum, endometrial protection of menopausal hormone therapy, etc., to increase patient satisfaction and compliance, so that the Mirena IUD can be worn to its effective service life.

[0013] See also Figure 1 , 2 , 3. The names of the parts are as follows: sleeve 1, push rod 2, push handle 3, notch 4, copper tube 5, scale 6, barb 7, knot 8, tail wire 9, Mirena IUD 10, lower binding wire 11, connecting wire between the first copper tube and the second copper tube 12, connecting wire between the fifth copper tube and the sixth copper tube 13, upper binding wire 14.
[0014] See also Figure 1 , 2 , the intrauterine contraceptive device placement sleeve comprises a sleeve 1 with scales, and the sleeve 1 has a notch 4 along the longitudinal direction. The notch 4 is 2 mm wide and the length of the notch 4 is the same as the length of the sleeve 1. Usage: The intrauterine contraceptive device placement sleeve is configured separately. Replace the sleeve 1 in the traditional Genie contraceptive ring pusher with the intrauterine contraceptive device placement sleeve (see Figure 2 ), the Mirena IUD 10 is bound against the Gini IUD, two horizontal binding lines are generated, namely the lower binding line 11 and the upper binding line 14, and the IUD is placed on the sleeve, and the notch 4 is used for the horizontal lower binding line 11 and the upper binding line 14 to pass through. The Mirena IUD 10 is outside the sleeve 1, and the Gini IUD is inside the sleeve 1, and the push handle 3 of the propeller is pushed, so that the Gini IUD moves upward and drives the Mirena IUD 10 to move up with it. After the Gini IUD is sent into the uterus, the Gini IUD is pushed to move up, so that the Gini IUD is hung on the uterine wall, and the Mirena IUD 10 is driven to be sent into the uterus together for support and fixation. Because the Mirena IUD 10 is bound to the Gini IUD, the Mirena IUD 10 is not affected by its single model, which overcomes the shortcomings of being easy to fall off due to the single model and different sizes of the uterine cavity. This intrauterine contraceptive device placement sleeve can be supplied independently, and can also be used in conjunction with the traditional Genie IUD pusher, that is, an additional intrauterine contraceptive device placement sleeve is separately provided in the pusher packaging box. When two IUDs need to be used at the same time, the sleeve in the traditional pusher can be replaced with the intrauterine contraceptive device placement sleeve, so that the two IUDs can be combined and inserted.
