Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an intrauterine device for removing an IUD used in obstetrics and gynecology. Background Technology

[0002] Women who do not wish to have children often choose to have an intrauterine device (IUD) implanted for long-term contraception. However, IUDs have a limited lifespan and must be removed promptly upon expiration; failure to remove them can affect a woman's health. Chinese patent (publication number: CN111467120B) discloses an intrauterine device removal tool for obstetrics and gynecology, comprising an expansion frame and a cross frame, and a removal tool slidably connected inside the expansion frame. Several support seats are fixed inside the expansion frame by screws, and support frames are slidably mounted inside the support seats. Several connecting seats are slidably connected to the inner wall of the expansion frame, and connecting frames are slidably connected inside the connecting seats. A rotating shaft is rotatably connected to the outer surface of the removal tool, and the connecting frames are rotatably connected to the removal tool via the rotating shaft. Several receiving blocks are integrally formed on the outer surface of the expansion frame.

[0003] However, existing methods of intrauterine IUD removal have some drawbacks during implementation, such as:

[0004] Most existing methods of IUD removal are performed under endoscopic guidance. The IUD is hooked with a metal hook and then pulled out directly. Since the IUD is usually in an extended state when it is in the uterus, it is easy to scratch the inner wall of the cervix during the process of pulling it out of the narrow cervix, causing damage to the cervical mucosa. Without the protection of the cervical mucosa, the inner wall of the cervix is ​​prone to inflammation. Therefore, the traditional IUD removal process poses a safety risk to women's health. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide an intrauterine device for gynecological and obstetric use, so as to solve the problem that the process of pulling the contraceptive ring out of the narrow cervix can easily scratch the inner wall of the cervix, causing damage to the inner wall mucosa of the cervix. Without the protection of the cervical mucosa, the inner wall of the cervix is ​​prone to inflammation, which poses a safety hazard to women's health.

[0006] Based on the above objectives, the present invention provides an intrauterine device for gynecological and obstetric use, comprising: a cervical probe mechanism and a vaginal probe mechanism, wherein the cervical probe mechanism further comprises a cervical probe tube and a push rod, the push rod being movably inserted into the cervical probe tube, one end of the push rod inside the cervical probe tube being a hemispherical structure, and a probe rubber sleeve being fitted at the bottom end of the cervical probe tube, the probe rubber sleeve being a conical structure, the top end of the conical probe rubber sleeve being a hemispherical structure, the hemispherical structure at the end of the push rod cooperating with the hemispherical structure at the end of the probe rubber sleeve, and an operating hole being provided at the center of the top end of the probe rubber sleeve;

[0007] The vaginal probe also includes a vaginal dilator sleeve, which is fitted over the cervical probe.

[0008] Furthermore, a first push plate is fixedly connected to the end of the push rod away from the hemispherical structure, and a second push plate is fixedly connected to the end of the cervical probe away from the probe rubber sleeve, with the first push plate cooperating with the second push plate.

[0009] Furthermore, the inner wall of the cervical probe is provided with an endoscope channel, which is arranged along the direction of the cervical probe and is used to insert an endoscope. An endoscope insertion hole is opened on the side of the probe rubber sheath, and the endoscope insertion hole is correspondingly arranged with the endoscope channel.

[0010] Furthermore, a first limiting ring is fixedly provided on the outer wall of one end of the vaginal expansion sleeve, and a second limiting ring is fixedly provided on the outer wall of the vaginal expansion sleeve on one side of the first limiting ring.

[0011] Furthermore, it also includes a cervical clamping mechanism, which further comprises a cervical clamp, a rotating seat, and a limiting ratchet. The rotating seat is fixedly disposed on both sides of the vaginal dilator. The cervical clamp is rotatably connected to the rotating seat and is rotatably connected to the vaginal dilator through the rotating seat. The limiting ratchet is rotatably sleeved on the outside of the vaginal dilator and is disposed between the first limiting ring and the second limiting ring. The limiting ratchet cooperates with the cervical clamp.

[0012] Furthermore, the cervical clamp is a single-sided lever structure, and the rotating shaft in the middle of the cervical clamp is rotatably connected to the rotating seat.

[0013] Furthermore, a resistance spring is installed at the pinching end of the cervical clamp, and the resistance spring is used to provide a holding force at the clamping end of the cervical clamp.

[0014] Furthermore, it also includes a uterine pull-out mechanism, which further comprises a sliding positioning ring, a limiting block, and a multi-stage limiting sleeve. The multi-stage limiting sleeve is movably sleeved outside the vaginal dilator, and is located on the side of the first limiting ring away from the second limiting ring. The sliding positioning ring is slidably sleeved outside the vaginal dilator, and is located on the side of the multi-stage limiting sleeve away from the first limiting ring. The limiting block is fixedly connected to the sliding positioning ring, and cooperates with the multi-stage limiting sleeve.

[0015] Furthermore, a baffle is fixedly provided between the sliding positioning ring and the limiting block.

[0016] The beneficial effects of this invention are:

[0017] This invention utilizes a push rod to hold the rubber sheath at the end of a cervical probe, inserting the probe into the uterus. A metal hook then passes through the rubber sheath and extends into the uterus from inside the probe, pulling the contraceptive ring into the probe. Finally, the entire probe is pulled out. Because the contraceptive ring is pulled out from inside the probe, it does not damage the cervical wall. Furthermore, the soft rubber sheath and smooth outer wall of the probe also prevent damage to the cervical wall. Therefore, the contraceptive ring can be safely removed, avoiding damage to the cervical mucosa and ensuring the woman's safety and health during the removal process. Attached Figure Description

[0034] like Figures 1-6 As shown: A gynecological intrauterine device for removing an IUD includes: a cervical probe mechanism 100 and a vaginal probe mechanism 200. The cervical probe mechanism 100 further includes a cervical probe tube 101 and a push rod 103. The push rod 103 is movably inserted into the cervical probe tube 101. One end of the push rod 103 inside the cervical probe tube 101 has a hemispherical structure. A probe rubber sleeve 105 is fitted onto the bottom end of the cervical probe tube 101. The probe rubber sleeve 105 has a conical structure, and the top of the conical probe rubber sleeve 105 has a hemispherical structure. The hemispherical structure at the end of the push rod 103 cooperates with the hemispherical structure at the end of the probe rubber sleeve 105. An operating hole is opened at the center of the top of the probe rubber sleeve 105.

[0035] Since the diameter of the cervical probe 101 is larger than the cervical opening, the cervical probe 101 cannot be directly inserted into the cervical opening. Therefore, a conical probe rubber sheath 105 needs to be fitted onto the end of the cervical probe 101 so that the thinner cone tip of the probe rubber sheath 105 enters the cervical opening first. As the probe rubber sheath 105 widens the cervical opening, the cervical probe 101 can smoothly pass through the cervix and enter the uterus.

[0036] Furthermore, if the probe rubber sheath 105 is directly fitted onto the end of the cervical probe tube 101, the diameter of the probe rubber sheath 105 will be larger than the diameter of the cervical probe tube 101, causing the probe rubber sheath 105 to protrude. When the cervical probe tube 101 is pulled out of the cervix, the protruding probe rubber sheath 105 may easily scratch the inner wall of the cervix. Therefore, it is necessary to provide an inward groove at the end of the cervical probe tube 101 so that the probe rubber sheath 105 will not protrude when fitted onto it, ensuring that the outer wall of the cervical probe tube 101 is smooth. In order to prevent the probe rubber sheath 105 from falling off, a harmless water can be applied between the probe rubber sheath 105 and the cervical probe tube 101 to make them more secure.

[0037] The push rod 103 is a rigid rod that can be made of any material, such as metal, wood, or plastic. The hemispherical structure at the top of the push rod 103 is designed to fit the inner wall of the probe rubber sheath 105. Since the probe rubber sheath 105 is made of a relatively soft material, it cannot directly penetrate the cervix. Therefore, the push rod 103 is used to lift the probe rubber sheath 105, giving it the strength to enter the cervix. At the same time, a lubricant can be applied to the end of the probe rubber sheath 105 to make it easier for it to enter the cervix.

[0038] The probe rubber sheath 105 has a small through hole at its top. When the push rod 103 pushes against the probe rubber sheath 105 and enters the cervix, the contact area between the hemispherical structure at the top of the push rod 103 and the probe rubber sheath 105 is large, so it will not pass through the through hole at the top of the probe rubber sheath 105. However, when the doctor uses a medical metal hook to forcefully push against the through hole at the top of the probe rubber sheath 105, the contact area between the medical metal hook and the probe rubber sheath 105 is small, and the medical staff pushes the medical metal hook forcefully. At the same time, the probe rubber sheath 105 has a certain degree of elasticity, which makes it easier for the medical metal hook to pass through the through hole at the top of the probe rubber sheath 105. When the medical metal hook catches the contraceptive ring, the medical staff only needs to pull the medical metal hook outward to pull the contraceptive ring into the cervical probe tube 101. At the same time, the probe rubber sheath 105 may also be pulled into the cervical probe tube 101. Afterward, it can be pushed out using the push rod 103.

[0039] The vaginal probe mechanism 200 also includes a vaginal dilator 201, which is sleeved on the outside of the cervical probe 101. A first limiting ring 202 is fixedly provided on the outer wall of one end of the vaginal dilator 201, and a second limiting ring 203 is fixedly provided on the outer wall of the vaginal dilator 201 on one side of the first limiting ring 202.

[0040] The vaginal dilator 201 needs to be inserted into the vagina during use. To facilitate its entry, the end of the vaginal dilator 201 that enters the vagina is equipped with a tapered opening. The inner diameter of the smallest part of the tapered opening needs to be larger than the outer diameter of the cervical probe 101. For easy observation, the observation gap between the cervical probe 101 and the tapered opening should be as large as possible. When inserting the vaginal dilator 201 into the vagina, the end with the smaller diameter should enter the vagina first, and then the cervical probe 101 should be passed through the vaginal dilator 201 and inserted into the cervix. Furthermore, to facilitate the entry of the vaginal dilator 201 into the vagina, a personal lubricant can be applied to its outer surface.

[0041] In use, first, the vaginal dilator 201 is inserted into the vagina of the person to be removed from the IUD, so that the medical staff can clearly observe the position of the cervix. Then, the push rod 103 is inserted into the cervical probe 101. The push rod 103 is used to hold the probe rubber sheath 105 at the end of the cervical probe 101. Then, the cervical probe 101 and the push rod 103 inside it are passed through the vaginal dilator 201 and inserted into the cervix. After the cervical probe 101 enters the uterus, the push rod 103 is removed and replaced with a medical metal hook. The medical metal hook is passed through the probe rubber sheath 105 and entered into the uterus. With the help of an endoscope, the IUD in the uterus is hooked into the cervical probe 101 and removed from the end of the cervical probe 101 that is outside the body. Then, the cervical probe 101 is carefully pulled out and finally the vaginal dilator 201 is removed.

[0042] This invention utilizes a push rod 103 to press against the insertion rubber sheath 105 at the end of the cervical probe 101, allowing the cervical probe 101 to be inserted into the uterus. A metal hook is then used to pass through the insertion rubber sheath 105 from inside the cervical probe 101 and extend into the uterus to pull out the contraceptive ring. Because the contraceptive ring is pulled out from inside the cervical probe 101, it does not damage the cervical wall. Furthermore, the soft material of the insertion rubber sheath 105 and the smooth outer wall of the cervical probe 101 also prevent damage to the cervical wall. Therefore, the contraceptive ring can be safely removed, avoiding damage to the cervical mucosa and ensuring the woman's safety and health during the removal process.

[0043] Furthermore, a first push plate 104 is fixedly connected to the end of the top rod 103 away from the hemispherical structure, and a second push plate 102 is fixedly connected to the end of the cervical probe tube 101 away from the probe rubber sleeve 105. The first push plate 104 and the second push plate 102 cooperate with each other.

[0044] By setting a first push plate 104 and a second push plate 102, after the push rod 103 is inserted into the cervical probe tube 101, in order to avoid excessive force pushing the push rod 103 out of the through hole at the end of the probe rubber sheath 105, the first push plate 104 can be set in a suitable position. By pinching the first push plate 104 and the second push plate 102 together, it can be ensured that the push rod 103 is pressed against the inner wall of the probe rubber sheath 105. There is no need to worry that when the cervical probe tube 101 enters the cervix, due to the long length of the push rod 103, the medical staff will use excessive force to puncture the probe rubber sheath 105.

[0045] Furthermore, the inner wall of the cervical probe 101 is provided with an endoscope channel 106, the endoscope channel 106 is arranged along the direction of the cervical probe 101, the endoscope channel 106 is used to insert an endoscope, and the side of the insertion rubber sheath 105 is provided with an endoscope insertion hole 107, the endoscope insertion hole 107 is correspondingly arranged with the endoscope channel 106;

[0046] When in use, after the cervical probe 101 is fully inserted into the uterus, the endoscope probe is passed through the endoscope channel 106 and the endoscope insertion hole 107 into the uterine cavity, so that medical personnel can observe the position and status of the IUD through the endoscope. Since the endoscope enters the uterine cavity through the cervical probe 101, the endoscope will not damage the inner wall of the cervix.

[0047] like Figures 7-8 As shown, the cervical clamping mechanism 300 further includes a cervical clamp 301, a rotating seat 302, and a limiting ratchet 304. The rotating seat 302 is fixedly disposed on both sides of the vaginal dilator 201. The cervical clamp 301 is rotatably connected to the rotating seat 302 and is rotatably connected to the vaginal dilator 201 through the rotating seat 302. The limiting ratchet 304 is rotatably sleeved on the outside of the vaginal dilator 201. The limiting ratchet 304 is disposed between the first limiting ring 202 and the second limiting ring 203, and the limiting ratchet 304 cooperates with the cervical clamp 301; the cervical clamp 301 is a single-sided lever structure, and the rotating shaft in the middle of the cervical clamp 301 is rotatably connected to the rotating seat 302; a resistance spring 303 is installed at the pinching end of the cervical clamp 301, and the resistance spring 303 is used to provide a clamping force to the clamping end of the cervical clamp 301;

[0048] The clamping end of the cervical clip 301 is bent inward to facilitate its entry into the vagina.

[0049] Among them, the cervical clamp 301 is a single-sided lever structure. The single-sided lever structure means that the power arm and the resistance arm of the cervical clamp 301 are on the same side. Unlike scissors, where the power arm and the resistance arm are on opposite sides of the fulcrum (middle pivot) and are arranged in a cross manner, the power arm and the resistance arm of the cervical clamp 301 in this application are on the same side of the fulcrum (middle pivot). Its structure is similar to a clothespin. The purpose of this arrangement is to facilitate the installation of the resistance spring 303. The elastic potential energy of the resistance spring 303 extending outward can enable the clamping end of the cervical clamp 301 to continuously have clamping force, without the need for manual pinching of the cervical clamp 301 to provide external force.

[0050] When in use, since the vaginal dilator 201 needs to be inserted into the vagina, and the cervical clamp 301 is installed outside the vaginal dilator 201, the clamping end of the cervical clamp 301 will first extend into the vagina. Medical personnel can observe the position of the cervical clamp 301 through the channel inside the vaginal dilator 201, and then pinch the tail of the cervical clamp 301 so that the cervical clamp 301 can clamp the two sides of the cervical opening. Then, the limiting ratchet 304 is rotated to open the cervical clamps 301 on both sides of the vaginal dilator 201 so that the cervical clamps 301 can open the cervical opening, which facilitates the entry of the cervical probe 101.

[0051] like Figures 9-10 As shown, the uterine pull-out mechanism 400 further includes a sliding positioning ring 401, a limiting block 403, and a multi-stage limiting sleeve 404. The multi-stage limiting sleeve 404 is movably sleeved outside the vaginal dilator 201 and is located on the side of the first limiting ring 202 away from the second limiting ring 203. The sliding positioning ring 401 is slidably sleeved outside the vaginal dilator 201 and is located on the side of the multi-stage limiting sleeve 404 away from the first limiting ring 202. The limiting block 403 is fixedly connected to the sliding positioning ring 401 and cooperates with the multi-stage limiting sleeve 404. A baffle 402 is fixedly provided between the sliding positioning ring 401 and the limiting block 403.

[0052] Among them, the sliding positioning ring 401 has a small thickness, so it will not protrude too much and make the user feel uncomfortable;

[0053] During use, since the uterus is naturally curved, and a curved uterus makes it difficult for the medical metal hook to retrieve the IUD, after the cervical clamp 301 holds the cervix, it needs to be pulled outward to straighten the uterus. Since the cervical clamp 301 is fixedly connected to the vaginal dilator 201, it is only necessary to pull the vaginal dilator 201 outward. After the sliding positioning ring 401 is placed on the outside of the vaginal dilator 201, since the area of ​​the baffle 402 is larger than the vaginal opening, the sliding positioning ring 401 will not slide into the vagina. By rotating the multi-level limiting sleeve 404, the multi-level limiting sleeve 404 gradually moves away from and is locked on the limiting block 403. Since the multi-level limiting sleeve 404 moves away from the limiting block 403, it will pull the vaginal dilator 201 outward through the first limiting ring 202, thus indirectly pulling the uterus outward to achieve a straightened state.

[0054] In summary:

[0055] When using it, first, insert the vaginal dilator 201 into the vagina of the person to be removed from the IUD, so that the medical staff can clearly observe the position of the cervix. Since the vaginal dilator 201 needs to be inserted into the vagina, and the cervical clamp 301 is installed outside the vaginal dilator 201, the clamping end of the cervical clamp 301 will first extend into the vagina. The medical staff can observe the position of the cervical clamp 301 through the channel inside the vaginal dilator 201. Then, pinch the tail of the cervical clamp 301 so that the cervical clamp 301 can clamp the two sides of the cervix. Then, rotate the limiting ratchet 304 to open the cervical clamps 301 on both sides of the vaginal dilator 201 so that the cervical clamps 301 can open the cervix, making it easier for the cervical probe 101 to enter.

[0056] Then, since the uterus is naturally curved, and a curved uterus is not convenient for medical metal hooks to retrieve the IUD, after the cervical clamp 301 clamps the cervix, it is necessary to pull the cervical clamp 301 outward to straighten the uterus. Since the cervical clamp 301 is fixedly connected to the vaginal dilator 201, it is only necessary to pull the vaginal dilator 201 outward. After the sliding positioning ring 401 is placed on the outside of the vaginal dilator 201, since the area of ​​the baffle 402 is larger than the vaginal opening, the sliding positioning ring 401 will not slide into the vagina. By rotating the multi-level limiting sleeve 404, the multi-level limiting sleeve 404 is gradually moved away from and locked on the limiting block 403. Since the multi-level limiting sleeve 404 will pull the vaginal dilator 201 outward through the first limiting ring 202 when it moves away from the limiting block 403, the uterus can be indirectly pulled outward to achieve the state of straightening the uterus.

[0057] Finally, insert the push rod 103 into the cervical probe 101, using the push rod 103 to hold the probe rubber sheath 105 at the end of the cervical probe 101. Then, pass the cervical probe 101 and the push rod 103 inside it through the vaginal dilator 201 into the cervix. After the cervical probe 101 enters the uterus, remove the push rod 103 and replace it with a medical metal hook. Pass the medical metal hook through the probe rubber sheath 105 into the uterus. With the help of an endoscope, hook the contraceptive ring in the uterus into the cervical probe 101 and remove the contraceptive ring from the end of the cervical probe 101 that is outside the body. Then, carefully pull out the cervical probe 101 and finally remove the vaginal dilator 201.

[0058] This invention utilizes a push rod 103 to press against the insertion rubber sheath 105 at the end of the cervical probe 101, allowing the cervical probe 101 to be inserted into the uterus. A metal hook is then used to pass through the insertion rubber sheath 105 from inside the cervical probe 101 and extend into the uterus to pull out the contraceptive ring. Because the contraceptive ring is pulled out from inside the cervical probe 101, it does not damage the cervical wall. Furthermore, the soft material of the insertion rubber sheath 105 and the smooth outer wall of the cervical probe 101 also prevent damage to the cervical wall. Therefore, the contraceptive ring can be safely removed, avoiding damage to the cervical mucosa and ensuring the woman's safety and health during the removal process.
