Description

Technical Field

[0001] This invention relates to the field of IUD fixation technology, and in particular to an intrauterine intelligent regulation and auxiliary reinforcement device. Background Technology

[0002] An intrauterine device (IUD) is a contraceptive device placed inside the uterine cavity. Because the devices used in the early days were mostly ring-shaped, they are commonly called IUDs, also known as intrauterine devices, or simply IUDs. There are many types of IUDs, and those commonly used in China include metal single rings, twisted rings, mixed rings, IUDs, and T-shaped rings.

[0003] Commonly used intrauterine devices (IUDs) are typically left loosely in the uterus, rather than being fixed in place, which carries the risk of spontaneous expulsion. Due to insufficient stability during insertion, they are also prone to displacement. Displaced IUDs can lose their contraceptive effect and cause pain, and in severe cases, vaginal bleeding, requiring removal or replacement, thus increasing the burden on the patient. This is especially true for patients with pathologically enlarged uterine cavities who require levonorgestrel-containing IUDs for treatment due to increased menstrual flow and dysmenorrhea. These patients often experience IUD expulsion or displacement, leading to more severe side effects and potentially requiring hysterectomy. Therefore, auxiliary devices are needed to secure the IUD within the uterus.

[0004] To address the aforementioned problems, an intrauterine intelligent regulation and auxiliary reinforcement device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an intrauterine intelligent regulation and reinforcement device, which solves the problem that common contraceptive rings in the background art are generally free-floating in the uterus and have the risk of spontaneous dislodgement. Due to insufficient installation stability, they are also prone to displacement.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intrauterine intelligent regulation and auxiliary reinforcement device, comprising an insertion tube that can be inserted into the uterine cavity and a pressing drive mechanism disposed on the insertion tube. A fixing component is disposed at the inner front end of the insertion tube. The fixing component is divided into a pushing mechanism and a needle puncture mechanism. The needle puncture mechanism includes a needle and a fixing line. The pressing drive mechanism is used to drive the pushing mechanism so that the needle layer inserts the fixing line into the myometrium of the uterine fundus and fixes the intrauterine device.

[0007] Furthermore, the pressing drive mechanism includes a first piston chamber, a first pipe, and a second pipe disposed inside the tube. The first pipe and the second pipe are respectively located at both ends of the first piston chamber. A first piston plate is slidably connected inside the first piston chamber, and a drive rod is fixedly connected to one side of the first piston plate.

[0008] Furthermore, the first pipe and the second pipe extend outward from the tail of the insertion pipe, and the tail of the insertion pipe is connected to a connector at the opening of the first pipe and the second pipe. The two sets of connectors are respectively connected to a first pinch ball and a second pinch ball via flexible hoses.

[0009] Furthermore, the fixing component includes a first fixing component, and the pushing mechanism includes a first sliding groove disposed inside the insertion tube. A second sliding groove and a first wire groove are disposed at the front end inside the insertion tube. The second sliding groove and the first wire groove are both connected to the first sliding groove. Two sets of second sliding grooves are disposed, and the two sets of second sliding grooves are located on both sides of the first wire groove. The second sliding groove has a certain inclination and extends outward to the outside of the top end of the insertion tube. The pushing mechanism includes a sliding plate slidably connected inside the first sliding groove, and the sliding plate is fixedly connected to one end of the drive rod.

[0010] Furthermore, the needle-punching mechanism includes a first needle head slidably connected inside the second sliding groove and a first fixed line placed inside the first wire groove. The tail end of the first needle head is fixedly connected to a movable rod. Movable grooves are provided on one side of the sliding plate, and the movable rod is movably disposed in the movable groove. An outward protrusion is provided near the top of the first needle head, and a groove is provided on the inner side of the first needle head. Both ends of the first fixed line pass through the groove and are provided with knots, and the knots are located in the receiving part.

[0011] Furthermore, the fixing component also includes a second fixing component, and the pushing mechanism also includes a second piston chamber disposed inside the insertion tube, and the second piston chamber communicates with the first piston chamber. A second piston plate is slidably connected inside the second piston chamber, and the second piston plate is fixedly connected to one end of the drive rod.

[0012] Furthermore, the pushing mechanism also includes an annular groove and an annular slide groove disposed inside the insertion tube near the top, and the annular groove and the annular slide groove are connected, the annular slide groove extends to the outside of the insertion tube, and the annular groove and the second piston chamber are connected by a connecting groove.

[0013] Furthermore, the top end of the insertion tube is provided with a second wire groove and a fitting groove. The needle-punching mechanism also includes an annular rod that is slidably connected inside the annular groove. One end of the annular rod is fixedly connected to a piston block, and the piston block is slidably connected inside the annular groove. The needle-punching mechanism also includes a second fixed wire provided inside the second wire groove, a second needle head fixedly connected to one end of the second fixed wire, and a needle seat fitted inside the fitting groove.

[0014] Furthermore, the inner side of the ring rod is provided with a receiving groove for accommodating the second fixing line. The other end of the second fixing line is fixedly connected to the needle seat. The outer wall of the second fixing line is provided with a fitting part corresponding to the receiving groove. Under the action of the second fixing line and the fitting part, the second needle head approaches the other end of the ring rod. The inside of the second needle head is provided with movable cavities at the top and bottom. A spring is installed in the movable cavity, and the spring is V-shaped. The inside of the needle seat is provided with a slot corresponding to the second needle head. The inside of the needle seat is also provided with a slot corresponding to the spring.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention provides an intrauterine intelligent control and reinforcement device. By pressing the first pinch ball, the drive rod pushes the sliding plate forward. The sliding plate extends the first needle outward from the second sliding groove and inserts it into the myometrium in a Y-shape. During insertion, the two ends of the first fixing line are brought into the myometrium. Then, pressing the second pinch ball retracts the first needle. When the first needle retracts, the knots at both ends of the first fixing line separate from the first needle from the receiving part and the groove and remain in the myometrium to fix the IUD. This effectively prevents the IUD from falling out or shifting. When the IUD needs to be removed, only the first fixing line needs to be cut. The operation is simple.

[0016] 2. The present invention provides an intrauterine intelligent control and auxiliary reinforcement device. After replacing the fixation component, pressing the first pinch ball causes the piston block and the ring rod to rotate counterclockwise. The second needle at the other end of the ring rod drives the ring rod and the second fixing line through the myometrium. Finally, the second needle and the needle seat are connected, and the spring clip is locked inside the slot. Then, pressing the second pinch ball again causes the ring rod to rotate clockwise and retract. At this time, since the second needle and the needle seat are connected, the ring rod separates from the second needle and the second fixing line. As the ring rod retracts from the myometrium into the ring groove, the second fixing line, the second needle, and the needle seat form a ring and fix the IUD to the inner wall of the uterine cavity. Then, the insertion tube is pulled out, and the needle seat separates from the groove. When it is necessary to remove the IUD, the second fixing line can be cut, and the needle seat can be clamped to remove the second needle and the second fixing line from the body. Then, the IUD can be removed from the body. This method does not leave the fixing thread in the body, and because the second fixing line, the second needle, and the needle seat form a ring, the fixation is more stable.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0020] Figures 1-4 As shown, an intrauterine intelligent regulation and reinforcement device includes an insertion tube 1 that can be inserted into the uterine cavity and a pressing drive mechanism 2 disposed on the insertion tube 1. The front end of the insertion tube 1 is provided with a fixing component, which is divided into a pushing mechanism and a needle puncture mechanism. The needle puncture mechanism includes a needle and a fixing line. The pressing drive mechanism 2 is used to drive the pushing mechanism so that the needle layer inserts the fixing line into the myometrium of the uterine fundus and fixes the IUD.

[0021] The pressing drive mechanism 2 includes a first piston chamber 21, a first pipe 22, and a second pipe 23 disposed inside the insertion tube 1. The first pipe 22 and the second pipe 23 are respectively located at both ends of the first piston chamber 21. A first piston plate 28 is slidably connected inside the first piston chamber 21, and a drive rod 29 is fixedly connected to one side of the first piston plate 28.

[0022] The first pipe 22 and the second pipe 23 extend outward from the tail of the insertion tube 1, respectively. The tail of the insertion tube 1 is connected to a connector 24 at the opening of the first pipe 22 and the second pipe 23. The two sets of connectors 24 are respectively connected to a first pinch ball 26 and a second pinch ball 27 via hoses 25. By pressing the first pinch ball 26, the gas inside the first pinch ball 26 enters the lower part of the first piston chamber 21, which can drive the first piston plate 28 and the drive rod 29 to move towards the front end of the insertion tube 1. By pressing the second pinch ball 27, the first piston plate 28 and the drive rod 29 can move towards the tail of the insertion tube 1.

[0023] The fixing component is selected as the first fixing component 4. The pushing mechanism includes a first sliding groove 41 disposed inside the insertion tube 1. A second sliding groove 42 and a first wire groove 43 are disposed at the front end inside the insertion tube 1. The second sliding groove 42 and the first wire groove 43 are both connected to the first sliding groove 41. Two sets of second sliding grooves 42 are disposed, and the two sets of second sliding grooves 42 are located on both sides of the first wire groove 43. The second sliding groove 42 has a certain inclination and extends outward to the outside of the top end of the insertion tube 1. The pushing mechanism includes a sliding plate 44 slidably connected inside the first sliding groove 41, and the sliding plate 44 is fixedly connected to one end of the drive rod 29.

[0024] The acupuncture mechanism includes a first needle 45 slidably connected inside a second sliding groove 42 and a first fixed wire 46 placed inside a first wire groove 43. A movable rod 451 is fixedly connected to the tail end of the first needle 45. Movable grooves 441 are provided vertically on one side of the sliding plate 44, and the movable rod 451 is movably disposed within the movable grooves 441. An outward protrusion 452 is provided near the top of the first needle 45, and a groove 454 is provided on the inner side of the first needle 45. Both ends of the first fixed wire 46 pass through the groove 454 and are provided with knots 461, which are located within a receiving portion 453. This mechanism is used in conjunction with an electronic endoscope. Insert the insertion tube 1 into the uterine cavity, with the front end of the insertion tube 1 facing the IUD and close to the inner wall of the uterine cavity. Then press the first pinch ball 26 to move the first piston plate 28 and the drive rod 29 to the front end. The drive rod 29, through the sliding plate 44, causes the first needle 45 to be inserted into the myometrium at the bottom of the uterine cavity. At this time, the first fixing line 46, under the action of the first needle 45, wraps around the IUD from left to right and is placed in the myometrium. The second pinch ball 27 causes the first fixing line 46 to retract. The knots 461 at both ends of the first fixing line 46 separate from the first needle 45 at the receiving part 453 and the groove 454. The first fixing line 46 is finally left at the bottom of the uterine cavity.

[0025] Specifically, during the operation, the insertion tube 1 is inserted into the uterine cavity through the vagina. With the help of an electronic endoscope, the insertion tube 1 is aligned with the IUD and placed close to the uterine cavity wall. Then, pressing the first pinch ball 26 causes the drive rod 29 to push the sliding plate 44 forward. The sliding plate 44 extends the first needle 45 outward from the second sliding groove 42 and inserts it into the myometrium in a Y-shape. During insertion, the two ends of the first fixing line 46 are brought into the myometrium. Then, pressing the second pinch ball 27 causes the first needle 45 to retract. When the first needle 45 retracts, the knots 461 at both ends of the first fixing line 46 separate from the first needle 45 from the receiving part 453 and the groove 454 and remain in the myometrium to fix the IUD. When it is necessary to remove the IUD, simply cut the first fixing line 46. The operation is simple. Example

[0026] Figure 1 and Figures 5-9 As shown, an intrauterine intelligent regulation and reinforcement device includes an insertion tube 1 that can be inserted into the uterine cavity and a pressing drive mechanism 2 disposed on the insertion tube 1. The front end of the insertion tube 1 is provided with a fixing component, which is divided into a pushing mechanism and a needle puncture mechanism. The needle puncture mechanism includes a needle and a fixing line. The pressing drive mechanism 2 is used to drive the pushing mechanism so that the needle layer inserts the fixing line into the myometrium of the uterine fundus and fixes the IUD.

[0027] The pressing drive mechanism 2 includes a first piston chamber 21, a first pipe 22, and a second pipe 23 disposed inside the insertion tube 1. The first pipe 22 and the second pipe 23 are respectively located at both ends of the first piston chamber 21. A first piston plate 28 is slidably connected inside the first piston chamber 21, and a drive rod 29 is fixedly connected to one side of the first piston plate 28.

[0028] The first pipe 22 and the second pipe 23 extend outward from the tail of the insertion tube 1, respectively. The tail of the insertion tube 1 is connected to a connector 24 at the opening of the first pipe 22 and the second pipe 23. The two sets of connectors 24 are respectively connected to a first pinch ball 26 and a second pinch ball 27 via hoses 25. By pressing the first pinch ball 26, the gas inside the first pinch ball 26 enters the lower part of the first piston chamber 21, which can drive the first piston plate 28 and the drive rod 29 to move towards the front end of the insertion tube 1. By pressing the second pinch ball 27, the first piston plate 28 and the drive rod 29 can move towards the tail of the insertion tube 1.

[0029] The fixing component is selected as the second fixing component 5. The pushing mechanism also includes a second piston chamber 51 disposed inside the insertion tube 1. The second piston chamber 51 is connected to the first piston chamber 21. A second piston plate 511 is slidably connected inside the second piston chamber 51. The second piston plate 511 is fixedly connected to one end of the drive rod 29.

[0030] The pushing mechanism also includes an annular groove 52 and an annular slide groove 53 disposed inside the insertion tube 1 near the top end, and the annular groove 52 and the annular slide groove 53 are connected. The annular slide groove 53 extends to the outside of the insertion tube 1. The annular groove 52 and the second piston chamber 51 are connected by a connecting groove 512. The top end of the insertion tube 1 is provided with a second line groove 54 and a fitting groove 55.

[0031] The needle-punching mechanism also includes an annular rod 56 slidably connected inside the annular groove 53. One end of the annular rod 56 is fixedly connected to a piston block 562, and the piston block 562 is slidably connected inside the annular groove 52. The needle-punching mechanism also includes a second fixing line 57 disposed inside the second line groove 54, a second needle head 58 fixedly connected to one end of the second fixing line 57, and a needle seat 59 fitted inside the fitting groove 55.

[0032] The inner side of the ring rod 56 is provided with a receiving groove 561 for accommodating the second fixing wire 57. The other end of the second fixing wire 57 is fixedly connected to the needle holder 59. The outer wall of the second fixing wire 57 is provided with a fitting part 571 corresponding to the receiving groove 561. The second needle head 58 approaches the other end of the ring rod 56 under the action of the second fixing wire 57 and the fitting part 571. The interior of the second needle head 58 is provided with movable cavities 581 at the top and bottom. A spring piece 582 is installed in the movable cavity 581, and the spring piece 582 is V-shaped. The interior of the needle holder 59 is provided with a slot 591 corresponding to the second needle head 58. The interior of the needle holder 59 is also provided with a slot corresponding to the spring piece. When the drive rod 29 moves towards the top of the insertion tube 1, it slides inside the second piston chamber 51 via the second piston plate 511, forcing the gas above the second piston chamber 51 into the annular groove 52. This causes the annular rod 56 to carry the second fixing line 57 and the second needle 58 through the muscle layer and finally combine with the needle seat 59. The second fixing line 57, the second needle 58, and the needle seat 59 form a ring. As the drive rod 29 retracts, the annular rod 56 retracts, and the annular rod 56 separates from the second fixing line 57 and the second needle 58, ultimately leaving only the second fixing line 57, the second needle 58, and the needle seat 59 in the uterine cavity.

[0033] Specifically, the fixing component in Embodiment 2 is an alternative structure to the fixing component in Embodiment 1. Pressing the second pinch ball 27 retracts the drive rod 29, causing the second piston plate 511 to slide backward within the second piston chamber 51. The piston block 562 in the annular groove 52 drives the annular rod 56 and the second needle 58 to rotate clockwise, ensuring that the second needle 58 is close to the needle seat 59 but not in contact during operation, preventing the second needle 58 from scratching the vaginal wall. Subsequently, the insertion tube 1 is inserted into the uterine cavity from the vagina. The insertion tube 1 is aligned with the IUD and placed close to the uterine wall. At this time, pressing the first pinch ball 26 causes the piston block 562 and the annular rod 56 to rotate counterclockwise. The second needle 58 at the other end of the annular rod 56 drives the annular rod 56 and the second fixing line 57 to pass through the muscle layer. Finally, the second needle 58 and the needle seat 59... The spring 582 is engaged and locked inside the slot 592. Then, the second pinch ball 27 is pressed again to rotate the ring rod 56 clockwise and retract it. At this time, since the second needle 58 is engaged with the needle seat 59, the ring rod 56 is separated from the second needle 58 and the second fixing line 57. As the ring rod 56 retracts from the muscle layer into the ring groove 52, the second fixing line 57, the second needle 58 and the needle seat 59 form a ring and fix the IUD to the inner wall of the uterine cavity. Then, the insertion tube 1 is pulled out, and the needle seat 59 is separated from the fitting groove 55. The advantage of this embodiment is that when it is necessary to remove the IUD, the second fixing line 57 can be cut, and the needle seat 59 can be clamped to remove the second needle 58 and the second fixing line 57 from the body. Then the IUD can be removed from the body. This method will not leave the fixing line in the body.
