Description

Technical Field

[0001] This invention relates to the field of fundus fixation technology, and in particular to a fundus fixation device for an intrauterine contraceptive device. Background Technology

[0002] Intrauterine devices (IUDs) are commonly used in clinical practice for contraception and treatment of gynecological diseases. Mirena, a medicated IUD, is widely used clinically. However, in patients with excessively large uterine cavities or poor uterine contractions, the abnormal uterine cavity shape and insufficient restraint from muscle contractions can easily cause the Mirena to migrate or fall out, leading to contraceptive or treatment failure and requiring further surgical adjustment or removal. To address this issue of unstable Mirena fixation, various auxiliary fixation methods have been developed clinically, including a combination of clamps and a nail gun. The clamps are used to secure the nail gun... The device is inserted into the uterine cavity and uses clips to position and fix the Mirena at a designated location on the fundus. In the existing clamping forceps and nail gun combination structure, the nail gun can be rotated and adjusted by turning a dial to adapt to different operating angles in the uterine cavity and meet positioning requirements. However, the dial lacks an effective limiting mechanism. During the critical operation of fixing the clip by pressing the handle, the operator may accidentally touch it or the resistance in the uterine cavity may cause the dial to rotate, resulting in the nail gun angle deviation, causing the clip fixing position to deviate, the Mirena to fail to be positioned, and other operational errors, which in turn affect the safety of the operation and the treatment effect. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0004] In view of the problems existing in the fundus fixation devices of the above and / or existing intrauterine contraceptive devices, the present invention is proposed.

[0005] Therefore, the problem to be solved by the present invention is that the rotating dial of the special clamp for fixing the bottom caliper of the Mi Yue Le Palace does not have an effective limit when pressing the handle to fix it, which is prone to causing operational errors.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a fundus clip fixing device for an intrauterine contraceptive device, comprising a main body component including a gun body, a mirror body connected to one side of the gun body, a rotating dial fixed to the mirror body, a nail gun mechanism fixed to the end of the mirror body, a clip disposed in the nail gun mechanism, a fixing handle fixed to the gun body, and a handle rotatably connected to the gun body.

[0007] The mounting assembly, located on one side of the rotating dial, includes a mounting component. The mounting component includes a mounting sleeve fixed to one side of the rotating dial. A mounting base is fixed to one side of the gun body. The mounting sleeve is inserted into the mounting base. A locking block is slidably disposed in the mounting base. A first spring is fixed to one side of the locking block. A locking groove is provided on the mounting sleeve.

[0008] As a preferred embodiment of the fundus locking device of the intrauterine contraceptive device of the present invention, the mounting base is connected to a turntable by a bearing, the turntable is provided with an arc-shaped groove, a round block is slidably arranged in the arc-shaped groove, and the round block is fixed on the locking block.

[0009] As a preferred embodiment of the fundus locking device for the intrauterine contraceptive device of the present invention, a push block is fixed on the turntable, a fixing block is fixed on the mounting base, and pins are inserted into the push block and the fixing block.

[0010] As a preferred embodiment of the fundus fixation device of the intrauterine contraceptive device of the present invention, a stop block is fixed on the fixing block.

[0011] As a preferred embodiment of the fundus locking device for the intrauterine contraceptive device of the present invention, the installation assembly further includes a limiting member disposed at the bottom of the installation base, the limiting member including a limiting block slidably disposed in the installation base, an extension block fixed on the limiting block, a second spring fixed on one side of the extension block, and a plurality of limiting grooves opened on the installation sleeve.

[0012] In a preferred embodiment of the fundus locking device for the intrauterine contraceptive device of the present invention, a lifting column is slidably connected to the bottom of the mounting base, a fixing sleeve is provided over the lifting column, and the fixing sleeve is fixed to the mounting base.

[0013] As a preferred embodiment of the fundus locking device of the intrauterine contraceptive device of the present invention, the mounting base is fixed with a fixed shaft at the bottom, a rotating plate is rotatably connected to the fixed shaft, a sliding groove is provided on the rotating plate, a first slider is fixed on the limiting block, and a second slider is fixed on the lifting column, and both the first slider and the second slider slide on the sliding groove.

[0014] As a preferred embodiment of the fundus locking device for the intrauterine contraceptive device of the present invention, there are two sliding grooves, and the bottom of the lifting column can contact the handle.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1, referring to Figures 1-4 and Figure 8 This is the first embodiment of the present invention, which provides a fundus locking device for an intrauterine device (IUD). The fundus locking device includes a main component 1, comprising a gun body 11, a mirror body 12 connected to one side of the gun body 11, a rotating dial 13 fixed on the mirror body 12, the rotating dial 13 being able to rotate relative to the gun body 11, thereby driving the mirror body 12 to rotate, a limit mechanism provided on the gun body 11 to prevent perforation, a nail gun mechanism 14 fixed to the end of the mirror body 12, a locking pin 15 disposed within the nail gun mechanism 14, a fixed handle 16 fixed on the gun body 11, a handle 17 rotatably connected to the gun body 11, a torsion spring disposed within the gun body 11, the torsion spring being used to maintain the initial position of the handle 17, and under no other external force, there is a certain angle between the handle 17 and the fixed handle 16, and this angle is at its maximum. The scope body 12 can be inserted into the uterine cavity. The nail gun mechanism 14 mainly consists of a nail magazine and a release device. The nail magazine is used to hold the clip 15, and the release device is used to release the compressed clip 15. Pressing the handle 17 reduces the angle between it and the fixed handle 16, and the nail gun mechanism 14 moves the clip 15 so that it can penetrate the fundus muscle layer. The clip 15 presses against the transverse arm of the Mirena intrauterine device, finally completing the auxiliary positioning and firmly fixing the Mirena to the fundus muscle layer to prevent it from shifting downward or falling off. The handle 17 is equipped with a pressure tactile feedback mechanism, which can further press the handle 17 to form an obstacle after the insertion depth reaches the safe limit, preventing the clip from penetrating the entire uterine layer due to excessive gripping force on the handle 17. This is existing technology, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0031] The Card15 is made of biocompatible metal or absorbable polymer material. It is shaped like a "U" nail with barbed ends to prevent it from coming out. The middle section is a flat pressure plate to hold the Mirena horizontal. The diameter of the nail gun mechanism 14 is ≤5mm. It can be operated through the hysteroscope body 12. Before fixation, 1 to 3 Card15s are pre-loaded in the nail cartridge.

[0032] After confirming the position of Mirena under hysteroscopy, the scope body 12 is moved to move the release device of the nail gun mechanism 14 to the vicinity of the transverse arm of Mirena and align it with the fundus. Then, the handle 17 is pressed, and the pin 15 is inserted into the fundus muscle layer, pressing down on the transverse arm of Mirena. The left and right ends of the transverse arm are fixed by a pin 15, forming a "two-point fixation" to improve the stability of the fixation.

[0033] Mounting component 2, located on one side of the rotating dial 13, includes mounting piece 21. Mounting piece 21 is configured to quickly mount the scope body 12 and the rotating dial 13 onto the gun body 11.

[0034] Mounting component 21 includes a mounting sleeve 211 fixed to one side of the rotating dial 13, and a mounting base 212 fixed to one side of the gun body 11. The mounting base 212 has a mounting groove corresponding to the mounting sleeve 211. The mounting sleeve 211 is inserted into the mounting base 212. A locking block 213 is slidably disposed in the mounting base 212. A first spring 214 is fixed to one side of the locking block 213. The other end of the first spring 214 is fixed in the mounting base 212. A locking groove 211-1 is provided on the mounting sleeve 211. There are four locking blocks 213, and the number of first springs 214 corresponds to the number of locking blocks 213. The locking groove 211-1 is annular. The first spring 214 is used to apply a continuous pushing force to the locking block 213 to ensure that the locking block 213 can engage with the locking groove 211-1. The locking block 213 is rectangular. A corresponding rectangular groove is provided in the mounting base 212 to restrict the locking block 213 to only move in a specific direction.

[0035] The mounting sleeve 211 can be inserted vertically into the mounting base 212. When the locking block 213 engages with the locking groove 211-1, the relative positions of the mounting base 212 and the mounting sleeve 211 will be locked, and the two cannot be separated. This ensures that the two can be stably connected during use. At the same time, since the locking groove 211-1 is annular, the locking block 213 will not obstruct the rotation of the mounting sleeve 211, and thus will not affect the rotation of the rotating dial 13.

[0036] Example 2, refer to Figures 3-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, a turntable 215 is connected to the bearing inside the mounting base 212. An arc-shaped groove 215-1 is opened inside the turntable 215. A round block 216 is slidably arranged inside the arc-shaped groove 215-1. The round block 216 is fixed on the locking block 213. The turntable 215 and the round block 216 are used to simultaneously unlock four engagements with the locking groove 211-1.

[0038] When the locking block 213 engages with the locking groove 211-1, the round block 216 is located in the arc groove 215-1, closest to the center of the turntable 215. When the turntable 215 rotates, the round block 216 will slide away from the center of the turntable 215 within the arc groove 215-1. Under the limitation of the rectangular groove of the mounting base 212, the locking block 213 will gradually move away from the locking groove 211-1 until the two are completely separated. After that, the mounting sleeve 211 can be directly and vertically pulled out of the mounting base 212 to complete quick disassembly, which facilitates the subsequent disinfection work.

[0039] Specifically, a push block 217 is fixed on the turntable 215, and a fixing block 218 is fixed on the mounting base 212. Through holes are formed in both the push block 217 and the fixing block 218, and pins 219 are inserted into them. Threaded grooves are formed in the through holes, and the pins 219 are threaded into the through holes. One end of the push block 217 extends to the outside of the mounting base 212. A rotation groove corresponding to the push block 217 is formed on the mounting base 212. Pushing the push block 217 moves it, causing the turntable 215 to rotate. When the push block 217 moves to the position where it coincides with the fixed block 218, the corresponding locking block 213 can engage with the locking groove 211-1. Then, the pin 219 is inserted into the through hole in the push block 217 and the fixed block 218 to restrict the movement of the push block 217, lock the position of the push block 217 relative to the mounting base 212, and thus lock the rotation of the turntable 215. This limits the movement of the locking block 213 and prevents the mirror body 12 from shifting due to the displacement of the locking block 213 during use.

[0040] Specifically, a stop block 218-1 is fixed on the fixed block 218. The stop block 218-1 prevents the operator from applying too much pushing force to the push block 217, and the stop block 218-1 can limit the extreme position of the movement of the fixed block 218.

[0041] Specifically, the mounting component 2 also includes a limiting member 22 set at the bottom of the mounting base 212. The limiting member 22 is set to ensure that the rotating dial 13 cannot rotate during the fixing process. In the non-fixed working state, the rotation of the rotating dial 13 is not restricted, and it does not affect the normal angle adjustment operation, adapting to diverse clinical surgical scenarios.

[0042] The limiting component 22 includes a limiting block 221 slidably disposed within the mounting base 212. The limiting block 221 is rectangular, and an extension block 222 is fixed on the limiting block 221. The mounting base 212 has a moving groove corresponding to the limiting block 221 and the extension block 222. A second spring 223 is fixed on one side of the extension block 222, and the other end of the second spring 223 is fixed on the mounting base 212. The mounting sleeve 211 has multiple limiting grooves 211-2. The second spring 223 is used to apply a continuous pushing force to the limiting block 221 to ensure that the limiting block 221 can engage with the limiting grooves 211-2. When the two are engaged, the mounting sleeve 211 cannot rotate relative to the mounting base 212, thereby locking the rotation of the rotating dial 13.

[0043] Specifically, a lifting column 224 is slidably connected to the bottom of the mounting base 212. A fixing sleeve 225 is provided on the outer sleeve of the lifting column 224. The fixing sleeve 225 is fixed on the mounting base 212. The fixing sleeve 225 is set to restrict the movement direction of the lifting column 224, so that it can only move up and down in the vertical direction.

[0044] Example 3, referring to Figures 1-8 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0045] Specifically, a fixed shaft 226 is fixed to the bottom of the mounting base 212, and a support block 226-1 is fixed on the fixed shaft 226. The support block 226-1 is fixed to the mounting base 212. A rotating plate 227 is rotatably connected to the fixed shaft 226. A sliding groove 227-1 is provided on the rotating plate 227. A first slider 228 is fixed on the limiting block 221, and a second slider 229 is fixed on the lifting column 224. Both the first slider 228 and the second slider 229 slide on the sliding groove 227-1. Through the cooperation of the first slider 228, the second slider 229 and the sliding groove 227-1, when the lifting column 224 moves vertically upward, the second slider 229 slides in the sliding groove 227-1, and the rotating plate 227 will rotate around the fixed shaft 226. At this time, the first slider 228 slides in another sliding groove 227-1, thereby driving the limiting block 221 to move downward, so that the limiting block 221 separates from the limiting groove 211-2.

[0046] When the lifting column 224 moves downward, the limiting block 221 can move upward with the cooperation of the first slider 228, the second slider 229 and the slide groove 227-1, and then engage with the limiting groove 211-2, thereby restricting the rotation of the rotating dial 13.

[0047] Specifically, there are two slides 227-1. The bottom of the lifting column 224 can contact the handle 17. In the initial state, the angle between the handle 17 and the fixed handle 16 is the largest. The torsion spring set at the handle 17 has a large elastic force, which is much greater than the elastic force of the second spring 223. At this time, the handle 17 contacts the lifting column 224 and applies an upward pushing force to the lifting column 224, which overcomes the pushing force of the second spring 223. At this time, the limiting block 221 is in the lowest position and is separated from the limiting groove 211-2. Therefore, it will not restrict the rotation of the rotating dial 13. The operator can adjust the rotation of the mirror body 12 according to the needs of use, so that the release of the nail gun mechanism 14 is aligned with the position to be fixed.

[0048] At the start of fixation, the operator presses the handle 17, making the angle between the handle 17 and the fixing handle 16 smaller. The handle 17 gradually separates from the lifting column 224. When the two are completely separated, the lifting column 224 is no longer subjected to upward thrust. Then, under the action of the second spring 223, the limiting block 221 can move upward and engage with the limiting groove 211-2, thereby restricting the rotation of the rotating dial 13. This prevents the rotating dial 13 from rotating during the fixation process, which would cause the release device of the nail gun mechanism 14 to shift, ultimately causing the card 15 to shift, thus affecting the auxiliary fixation effect of the IUD in the Mirena.

[0049] Specifically, one end of the locking block 213 is inclined. By setting it in an inclined shape, when the mounting sleeve 211 is vertically inserted into the mounting base 212, the inclined surface of the locking block 213 will first contact the end face of the mounting sleeve 211. The end face of the mounting sleeve 211 applies a pushing force to its inclined surface, and the first spring 214 is compressed. At this time, the locking block 213 will not hinder the movement of the mounting sleeve 211. When the mounting sleeve 211 moves to the limit position in the mounting base 212, all four locking blocks 213 will be coaxial with the locking groove 211-1. Under the action of the first spring 214, all four locking blocks 213 will engage with the locking groove 211-1, thereby preventing the mounting sleeve 211 from separating from the mounting base 212.

[0050] Specifically, the lifting column 224 is provided with a protrusion, and the fixing sleeve 225 is provided with a corresponding groove. The protrusion and the groove correspond to each other, ensuring that the lifting column 224 can be raised and lowered stably within the fixing sleeve 225, and the two will not separate.

[0051] In use, the mounting sleeve 211 is vertically inserted into the mounting base 212. The inclined surface of the locking block 213 will first contact the end face of the mounting sleeve 211. The end face of the mounting sleeve 211 applies a pushing force to its inclined surface, and the first spring 214 is compressed. At this time, the locking block 213 will not hinder the movement of the mounting sleeve 211. When the mounting sleeve 211 moves to the limit position in the mounting base 212, all four locking blocks 213 will be coaxial with the locking groove 211-1. Under the action of the first spring 214, all four locking blocks 213 will engage with the locking groove 211-1, thereby preventing the mounting sleeve 211 from separating from the mounting base 212. The pin 219 is inserted into the through hole in the push block 217 and the fixing block 218 to restrict the movement of the push block 217 and lock the position of the push block 217 relative to the mounting base 212, thereby locking the rotation of the turntable 215. Thus, the movement of the locking block 213 is limited, preventing the mirror body 12 from shifting due to the displacement of the locking block 213 during use.

[0052] After confirming the position of the Mirena under hysteroscopy, the scope body 12 is moved, causing the release mechanism of the nail gun 14 to move near the transverse arm of the Mirena and align it with the fundus. Then, the operator presses the handle 17, reducing the angle between the handle 17 and the fixed handle 16. The handle 17 gradually separates from the lifting column 224. Once completely separated, the lifting column 224 is no longer subjected to upward thrust. Then, under the action of the second spring 223, the limiting block 221 can move upward and engage with the limiting groove 211-2, from... The rotation of the rotating dial 13 is restricted to prevent the release mechanism of the nail gun mechanism 14 from shifting during the fixing process, which would cause the card 15 to move and affect the auxiliary fixing effect of the IUD in the Mirena. After fixing, the handle 17 is released, and the torsion spring drives the handle 17 to return to its original position, applying an upward thrust to the lifting column 224, which overcomes the thrust of the second spring 223. At this time, the limiting block 221 is in the lowest position and separates from the limiting groove 211-2, so it will not restrict the rotation of the rotating dial 13.

[0053] When it is necessary to disassemble the mirror body 12, remove the pin 219 from the push block 217 and the fixing block 218, and then push the push block 217 to drive the turntable 215 to rotate. The round block 216 will slide in the arc groove 215-1 away from the center of the turntable 215. Under the limit of the rectangular groove of the mounting base 212, the locking block 213 will gradually move away from the locking groove 211-1 until the two are completely separated. Then the mounting sleeve 211 can be directly pulled out vertically from the mounting base 212 to complete the quick disassembly and facilitate the subsequent disinfection work.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
