Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a device for stopping bleeding at the vaginal wall puncture point after assisted reproductive egg retrieval. Background Technology

[0002] Assisted reproductive egg retrieval surgery is a minimally invasive puncture procedure performed under vaginal ultrasound guidance. As a crucial step in the success of assisted reproduction, safe and effective hemostasis after the procedure directly affects surgical safety, complication prevention, and patient experience. Currently used hemostasis methods, such as gauze packing, simple mechanical compression devices, and basic balloon-type devices, generally have the following drawbacks: relying solely on friction, external traction, or natural cavity contraction for fixation, they are prone to displacement and dislodgement; the compression range is too large, and the pressure is dispersed, making it difficult to accurately apply pressure to the puncture site; the structure is too simple to adapt to differences in vaginal size and puncture location among different patients, resulting in unstable hemostasis, potential damage to surrounding tissues, and impact on patient comfort. Therefore, developing a vaginal wall puncture point hemostasis device that can achieve precise positioning, stable fixation, adapt to individual differences, and effectively improve hemostasis has significant clinical value and application prospects.

[0003] Patent CN116509487B discloses a hemostatic device for vaginal wall puncture points after assisted reproductive technology (ART) egg retrieval. The device includes a push tube, a rotating ring, a push frame, a hemostatic cotton ball, and a dilation mechanism. The push tube is rotatably connected to the rotating ring, and the push frame is slidably connected inside the push tube. A hemostatic cotton ball for hemostasis at the puncture point is placed inside the push tube, and the push tube is equipped with a dilation mechanism. In this invention, the rotating plate rotates counterclockwise to dilate the patient's vagina. The push frame then pushes the hemostatic cotton ball to the right, pressing it against the puncture point to stop bleeding. The medication layer reduces inflammation in the patient. Finally, rotating the rotating ring counterclockwise disengages the pull cord from the push tube, allowing the hemostatic cotton ball to be quickly removed by pulling the cord. The operation is convenient.

[0004] However, this hemostatic device still has the following problems when in use: (1) The hemostatic device mainly relies on the friction of the push tube and the dilation plate for fixation, and is easily displaced by the patient's movement or vaginal peristalsis; (2) The hemostatic device relies solely on the pressure of the cotton ball, which has a relatively simple function. Blood may flow into the deep part of the vagina or vulva, increasing the risk of infection. Furthermore, the cotton ball has a large pressure range, which can easily compress surrounding normal tissues. Summary of the Invention

[0005] To address the aforementioned problems, this invention aims to provide a hemostasis device for vaginal wall puncture points after assisted reproductive technology (ART) egg retrieval. The device uses a top and side fixing airbags in the fixing mechanism to clamp and fix the cervix, a hemostasis airbag in the hemostasis mechanism to achieve precise pressure hemostasis at the puncture point, and an anti-overflow airbag in the anti-overflow mechanism to form a closed barrier on both sides of the hemostasis airbag, effectively isolating the bleeding area at the puncture point, improving hemostasis, flexibly adapting to different patient differences, providing high patient comfort, and improving the postoperative recovery experience.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A device for stopping bleeding at vaginal wall puncture points after assisted reproductive technology (ART) egg retrieval, comprising: a housing, and further comprising: A fixing mechanism, movably disposed inside the housing, is used to clamp and fix the cervix. A hemostatic mechanism is symmetrically arranged on both sides of the fixing mechanism to apply pressure to the puncture point for hemostasis; An anti-spillage mechanism, connected to the hemostasis mechanism, is used to seal the puncture site area to prevent blood from spilling out.

[0007] Furthermore, the fixing mechanism includes: A movable rod extends through and is movably disposed inside the housing; A top airbag is located at the top of the movable rod; Two connectors are symmetrically and movably arranged on both sides of the movable rod, and each connector has two fixed airbags symmetrically provided at its end.

[0008] Furthermore, the fixing mechanism also includes: Two first springs are respectively disposed between the movable rod and the corresponding connecting member; Two pull ropes are inserted through the inside of the movable rod and are respectively connected to the two connecting pieces.

[0009] Furthermore, the hemostatic mechanism includes: Two movable columns are symmetrically arranged on both sides of the fixed mechanism and move through the housing. Two first support rods are respectively rotatably mounted on the corresponding movable columns; Two hemostatic airbags are respectively mounted on the corresponding first support rod.

[0010] Furthermore, the hemostatic mechanism also includes: A fixing bar is provided between the two movable columns for synchronously pushing the two movable columns; A dial, mounted on the housing, is used to rotate the two movable columns outward or inward simultaneously.

[0011] Furthermore, the spillover prevention mechanism includes: Two second support rods are slidably mounted on the corresponding movable columns and are rotatably connected to the corresponding first support rods; Two anti-overflow airbag assemblies are rotatably mounted on their respective second support rods; Two drive components are respectively disposed inside the corresponding movable column and connected to the corresponding anti-overflow airbag components, for driving the two anti-overflow airbag components to rotate.

[0012] Furthermore, the second support rod is also provided with: The support block is mounted on the second support rod; A rotating shaft is mounted on the support block and is rotatably connected to the anti-overflow airbag assembly.

[0013] Furthermore, the anti-outflow airbag assembly includes: A rotating bushing is movably fitted onto the rotating shaft; An arc-shaped telescopic rod is disposed inside the rotating bushing and connected to the drive assembly; Two anti-overflow airbags are symmetrically arranged on both sides of the rotating bushing.

[0014] Furthermore, the housing is also provided with: An inflation / deflation button is located on the housing. The second gas conduit is connected to the inflation / deflation button, the two hemostatic airbags, and the two anti-overflow airbag assemblies.

[0015] The beneficial effects of this invention are: (1) The present invention uses the top airbag and the two side airbags in the fixing mechanism to clamp the cervix together to achieve “targeted clamping and positioning”, directly anchoring the core fixing point in the vagina, completely getting rid of the dependence on vaginal wall friction or external traction in the traditional method. Even if the patient moves or the vagina peristalsis, the device can still maintain a stable position and ensure that the hemostasis structure is always aligned with the puncture point. (2) The present invention uses an independently adjustable hemostatic balloon, and the compression range can be strictly limited to the local area of ​​the puncture point to avoid unnecessary compression and damage to the surrounding normal tissues. With the help of the dial to adjust the angle, it can further ensure that the hemostatic balloon is directly facing the puncture point, effectively improve the hemostatic effect, and is easy to remove. It is not easy to cause adhesion risk, and the patient's comfort is high, which is conducive to improving the postoperative recovery experience. (3) By setting up an anti-overflow balloon assembly, the present invention forms a closed barrier on both sides of the hemostatic balloon, effectively isolating the bleeding area at the puncture point and preventing blood from spreading to the deep part of the vagina or vulva. This not only reduces the possibility of cross-infection, but also provides a clear observation window for medical staff to facilitate real-time assessment of hemostasis. (4) The fixation mechanism and hemostasis mechanism of the present invention can be independently inflated and deflated, which can flexibly adapt to the differences in cervical size, vaginal shape and puncture point position of different patients. The continuous operation is achieved through the push rod, dial wheel, first spring, second spring, inflation / deflation button, pull rope to assist in retraction, etc. The operation process is simplified through mechanical transmission, reducing the dependence on the operator's personal experience and improving the convenience and efficiency of clinical use.

[0033] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments, and not all of the embodiments.

[0034] In the description of this invention, it should be understood that the terms "front", "rear", "left", "right", "upper", "lower", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0035] Example 1: See attached document Figure 1-16 This application discloses a hemostasis device for vaginal wall puncture points after assisted reproductive egg retrieval, comprising: a housing 1, wherein a fixing mechanism 2 is movably provided inside the housing 1 for clamping and fixing the cervix; hemostasis mechanisms 3 are symmetrically provided on both sides of the fixing mechanism 2 for applying pressure to stop bleeding at the puncture point; and an anti-overflow mechanism 4 is connected to the hemostasis mechanism 3 for sealing the puncture point area to prevent blood from overflowing.

[0036] Further, the fixing mechanism 2 includes a movable rod 5, two first springs 6, a first gas pipe 7, a top airbag 8, two connecting pieces 9, and four fixed airbags 10. The movable rod 5 passes through and is movably disposed inside the housing 1. The top airbag 8 is disposed at the top of the movable rod 5. The two connecting pieces 9 are symmetrically and rotatably disposed on both sides of the movable rod 5. Each end of the connecting piece 9 is symmetrically provided with two fixed airbags 10. The first gas pipe 7 passes through the movable rod 5 and communicates with the top airbag 8 and the four fixed airbags 10 for inflating the top airbag 8 and the four fixed airbags 10. The two first springs 6 are respectively disposed between the movable rod 5 and the corresponding connecting piece 9, with one end connected to the movable rod 5 and the other end abutting against the corresponding connecting piece 9, for ejecting the two connecting pieces 9 from inside the housing 1.

[0037] In the initial state, the end of the movable rod 5 near the top airbag 8 is located inside the housing 1, and the two connecting pieces 9 and the four fixed airbags 10 are also located inside the housing 1. At this time, the suspended ends of the two first springs 6 respectively abut against the corresponding connecting pieces 9, and the two first springs 6 are compressed. When the device is used, the end of the movable rod 5 away from the top airbag 8 is pushed, so that the end of the movable rod 5 near the top airbag 8 extends out from inside the housing 1. At the same time, the two connecting pieces 9 are ejected from inside the housing 1 under the elastic action of the corresponding first springs 6. At this time, the top airbag 8 and the four fixed airbags 10 are inflated through the first gas pipe 7 until the top airbag 8 and the four fixed airbags 10 clamp the cervix, thereby achieving stable fixation of the device.

[0038] As attached Figure 2 As shown, the overall length of the device in its initial state is about 15 cm, and the diameter of the shell 1 (i.e., the overall diameter of the device) is about 5 cm, ensuring that the patient does not experience significant discomfort when the device is placed inside the patient's body.

[0039] Furthermore, the hemostasis mechanism 3 includes two movable columns 11, which are symmetrically arranged on both sides of the fixing mechanism 2 and penetrate the housing 1. Two push rods 14 are respectively connected to the two movable columns 11. By pushing the two push rods 14, the two movable columns 11 can be extended out of the housing 1. A fixing strip 15 is connected between the two push rods 14 to ensure that the moving distance of the two push rods 14 is synchronized, thereby ensuring that the extension height of the two movable columns 11 is consistent. A dial wheel 13 is provided on the housing 1. Rotating the dial wheel 13 can make the two movable columns 11 rotate outward or inward at the same time. Each movable column 11 has a groove, and a first support rod 19 is rotatably arranged in the groove. A hemostatic airbag 18 is provided on the first support rod 19. The hemostatic airbag 18 is used to compress the puncture point for hemostasis.

[0040] Furthermore, the anti-spillage mechanism 4 includes two second springs 17, two anti-spillage airbag assemblies 20, two second support rods 21, and two drive assemblies 22. The two second support rods 21 are slidably disposed in the grooves of the corresponding movable column 11 and are rotatably connected to the corresponding first support rod 19. The two anti-spillage airbag assemblies 20 are rotatably disposed on the corresponding second support rods 21 to seal the puncture point area and prevent blood from spilling out. The two second springs 17 are also disposed in the grooves of the corresponding movable column 11, with one end connected to the corresponding movable column 11 and the other end abutting against the corresponding second support rod 21 to push the second support rod 21 to slide upward. The two drive assemblies 22 are disposed in the grooves of the corresponding movable column 11 at the ends away from the second springs 17 and are connected to the corresponding anti-spillage airbag assemblies 20 to drive the anti-spillage airbag assemblies 20 to rotate.

[0041] Furthermore, the drive assembly 22 includes a linear drive rod 23 and a fluid conduit 24 communicating with the linear drive rod 23. The fluid conduit 24 connects the linear drive rod 23 and the anti-overflow airbag assembly 20. When the second support rod 21 slides upward, the linear drive rod 23 is compressed, and the fluid inside the linear drive rod 23 enters the anti-overflow airbag assembly 20 along the fluid conduit 24, driving the anti-overflow airbag assembly 20 to rotate.

[0042] More specifically, the second support rod 21 is also provided with a support block 25, the support block 25 is provided with a rotating shaft 26, the anti-overflow airbag assembly 20 is movably sleeved on the rotating shaft 26, and the rotating shaft 26 is also provided with a contact point 27.

[0043] Furthermore, the anti-outflow airbag assembly 20 includes a rotating bushing 28, an arc-shaped telescopic rod 29, a communicating chamber 30, and two anti-outflow airbags 31. The rotating bushing 28 is movably sleeved on the rotating shaft 26, and a groove is formed on the inner side wall of the rotating bushing 28. When the rotating bushing 28 is engaged with the rotating shaft 26, the contact point 27 is precisely slidably engaged in the groove of the rotating bushing 28. The arc-shaped telescopic rod 29 is also provided in the groove of the rotating bushing 28. Rod 29 is connected to the fluid pipeline 24. When the fluid pipeline 24 delivers fluid into the arc-shaped telescopic rod 29, the arc-shaped telescopic rod 29 extends, thereby pushing the contact point 27. The contact point 27 causes the rotating bushing 28 to rotate the entire anti-overflow airbag assembly 20 through the reaction force. The connecting chamber 30 is disposed on the rotating bushing 28, and the two anti-overflow airbags 31 are symmetrically disposed at both ends of the connecting chamber 30 and are both connected to the connecting chamber 30.

[0044] In the initial state, both movable columns 11 and both hemostatic airbags 18 are located inside the housing 1, with both hemostatic airbags 18 positioned near the movable rod 5. The two anti-overflow airbag assemblies 20 are parallel to their corresponding second support rods 21. The two contacts 27 abut against the telescopic ends of their corresponding arc-shaped telescopic rods 29, and the two second springs 17 are compressed. When the device is in use, pushing the two push rods 14 causes the two movable columns 11 to extend from the housing 1. At this time, under the elastic action of the two second springs 17, the two second support rods 21 slide upwards, causing the connecting ends of the corresponding first support rod 19 and second support rod 21 to pop out from the grooves of the corresponding movable columns 11. Simultaneously, the two linear drive rods 23 are compressed. The fluid inside the two linear drive rods 23 enters the corresponding arc-shaped telescopic rods 29 along the corresponding fluid pipes 24. The two arc-shaped telescopic rods 29 extend, pushing the two contact points 27, and the two rotating bushings 28 begin to rotate. Since the groove length on each rotating bushing 28 only supports the corresponding anti-overflow airbag assembly 20 to rotate 90 degrees, the two anti-overflow airbag assemblies 20 stop rotating when they are perpendicular to the corresponding second support rod 21. At this time, the two anti-overflow airbags 31 on each anti-overflow airbag assembly 20 are symmetrically distributed on both sides of the corresponding hemostatic airbag 18 to ensure the sealing effect on the puncture point area. Then, the dial 13 is rotated to make the two movable columns 11 rotate outwards simultaneously until the two hemostatic airbags 18 are facing the puncture point.

[0045] Furthermore, the housing 1 is provided with an inflation / deflation button 12, and a second gas pipe 16 is connected to the inflation / deflation button 12. The second gas pipe 16 is located inside the two movable columns 11 and is connected to the two hemostatic airbags 18 and the two communicating chambers 30. Pressing the inflation / deflation button 12 can inflate the two hemostatic airbags 18 and the four anti-overflow airbags 31. Pulling out the inflation / deflation button 12 will deflate the two hemostatic airbags 18 and the four anti-overflow airbags 31.

[0046] Furthermore, each of the two connecting members 9 is provided with a pull rope 32, and both pull ropes 32 pass through the interior of the movable rod 5. After hemostasis is completed, pull the two pull ropes 32 to pull the two connecting members 9 closer to the movable rod 5 until the two first springs 6 are compressed again. At this time, pull the end of the movable rod 5 away from the top airbag 8 so that the movable rod 5 and the two connecting members 9 are retracted into the housing 1.

[0047] The working principle of the device described in this embodiment is as follows: First, push the movable rod 5 away from the top airbag 8 so that the movable rod 5 extends out of the inside of the housing 1. At the same time, the two connecting pieces 9 pop out from the inside of the housing 1 under the elastic action of the two first springs 6. At this time, the top airbag 8 and the four fixed airbags 10 are inflated through the first gas pipe 7 until the top airbag 8 and the four fixed airbags 10 clamp the cervix. Then, push the two push rods 14 to make the two movable columns 11 extend out of the housing 1. At this time, the two second support rods 21 slide upward under the elastic action of the two second springs 17, causing the connecting ends of the corresponding first support rods 19 and second support rods 21 to pop out from the grooves of the corresponding movable columns 11. At the same time, the two linear drive rods 23 are compressed, and the fluid enters the interior of the corresponding arc-shaped telescopic rods 29 along the corresponding fluid pipes 24. The two arc-shaped telescopic rods 29 extend and push the two contact points 27. The two rotating bushings 28 drive the two anti-overflow airbag assemblies 20 to rotate until they are perpendicular to the corresponding second support rods 21 and then stop. At this time, the two anti-overflow airbags 31 on each anti-overflow airbag assembly 20 are symmetrically distributed on both sides of the corresponding hemostatic airbag 18. Then, turn the dial 13 to make the two movable columns 11 rotate outwards at the same time until the two hemostatic airbags 18 are facing the puncture point. Press the inflation / deflation button 12 to inflate the two hemostatic airbags 18 and the four anti-overflow airbags 31 to achieve compression hemostasis at the puncture point and closure of the puncture point area to prevent blood from overflowing. After hemostasis is completed, first pull up the inflation / deflation button 12 to deflate the two hemostatic airbags 18 and the four anti-overflow airbags 31. Then, turn the dial 13 in the opposite direction to make the two movable columns 11 rotate inward at the same time, and retract the two hemostatic airbags 18 and the four anti-overflow airbags 31 into the inside of the device. Then, deflate the top airbag 8 and the four fixed airbags 10 through the first gas pipe 7. Then, pull the two pull ropes 32 to pull the two connecting parts 9 towards the movable rod 5 until the two first springs 6 are compressed again. Then, pull the end of the movable rod 5 away from the top airbag 8 to retract the movable rod 5 and the two connecting parts 9 into the housing 1 and remove the device.

[0048] Specific application examples: Following egg retrieval in assisted reproductive technology, safe and effective hemostasis of the vaginal wall puncture site is crucial to reduce the risk of postoperative infection. Currently used hemostasis methods, such as gauze packing, simple mechanical compression, and basic balloon-type hemostasis, all have limitations: gauze packing lacks reliable fixation and easily shifts with patient movement; simple mechanical compression devices often rely on external fixation straps, which are prone to loosening and difficult to conform to the irregular shape of the vagina; while basic balloon-type devices can prevent slippage deeper, they cannot prevent the balloon from rotating or shifting, causing the compression point to deviate from the puncture site. Furthermore, existing methods generally have a large compression range and dispersed pressure, failing to precisely focus on the puncture site, which not only affects hemostasis but may also cause damage to surrounding tissues and patient discomfort. A vaginal wall puncture site hemostasis device that can achieve precise positioning, stable fixation, adapt to individual differences, and effectively improve hemostasis can replace traditional hemostasis methods, improving the accuracy and stability of hemostasis while also enhancing the patient's postoperative recovery experience.

[0049] Taking a vaginal wall puncture point hemostasis device after assisted reproductive egg retrieval as an example, the usage process of this device will be explained in detail: Step 1: After inserting the device into the patient's vagina near the cervix, push the movable rod 5 to make the two connecting pieces 9 pop out from the inside of the housing 1, and inflate the top airbag 8 and the four fixed airbags 10 through the first gas pipe 7 until the top airbag 8 and the four fixed airbags 10 clamp the cervix. Step 2: Push the two push rods 14 to make the two movable columns 11 extend out of the housing 1. When the two anti-overflow airbag assemblies 20 rotate to be perpendicular to the corresponding second support rod 21, rotate the dial 13 until the two hemostatic airbags 18 are directly opposite the puncture point. Step 3: Press the inflation / deflation button 12 to inflate the two hemostatic airbags 18 and the four anti-overflow airbags 31 to begin applying pressure to the puncture site to stop bleeding; Step 4: After the hemostasis is completed, first pull up the inflation / deflation button 12 to deflate the two hemostatic airbags 18 and the four anti-overflow airbags 31. Then turn the dial 13 in the opposite direction to retract the two hemostatic airbags 18 and the four anti-overflow airbags 31. Step 5: Then deflate the top airbag 8 and the four fixed airbags 10; Step 6: Pull the two ropes 32 until the two first springs 6 are compressed again, then pull the movable rod 5 to retract the two connecting parts 9 into the housing 1 and remove the device.
