Description

Technical Field

[0001] This utility model relates to the field of artificial membrane rupture, and in particular to an artificial membrane rupture device for obstetrics and gynecology. Background Technology

[0002] If labor progresses slowly, an artificial rupture of membranes can be used. After the membranes rupture, amniotic fluid flows out, and the fetal head directly adheres to the lower segment of the uterus and the internal os of the cervix, which can induce reflexive uterine contractions, thereby strengthening the contractions and accelerating the progress of labor.

[0003] A search revealed Chinese Patent Publication No. CN221105978U, which discloses an artificial membrane rupture device for obstetrics and gynecology. The device includes a fixed tube with a membrane rupture mechanism on its outer side. The membrane rupture mechanism includes a connecting tube with a funnel fixedly connected to its top end. Fixing frames are fixedly connected to the inner walls of both the fixed tube and the connecting tube. A threaded rod is threaded onto the inner walls of both fixing frames. Two drainage pipes are fixedly connected to the outer surface of the connecting tube. A fixing seat is fixedly connected to the top end of the threaded rod. A fixing frame is fixedly connected to the upper surface of the fixing seat. A membrane rupture needle is engaged with the interior of the fixing frame and the interior of the fixing seat. Two sets of cross-threaded nails are positioned above the fixing frame. Two trapezoidal seats are fixedly connected to the upper surface of the fixing frame, and a bolt is provided on the outer side of each trapezoidal seat. This utility model, by incorporating a fixed tube, a connecting tube, a fixing frame, a lead screw, and a membrane-rupturing needle, can control the movement speed of the membrane-rupturing needle, thereby controlling the depth of the puncture. This avoids the problem of potential damage to the fetus inside the amniotic fluid due to improper depth control during the puncture process.

[0004] In the above technology, by setting up a fixed tube, a connecting tube, a fixed frame, a screw, and a rupture needle, the moving speed of the rupture needle can be controlled. However, there is a certain distance between the birth canal opening and the amniotic membrane, and the speed adjustment is relatively slow because the rupture needle is moved only by rotating the screw. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an artificial membrane rupture device for obstetrics and gynecology, which aims to improve the problem of slow speed in adjusting the position of the membrane rupture needle by rotating the screw in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an artificial membrane rupture device for obstetrics and gynecology, comprising a housing, a fixed ring fixedly connected to the inner wall of the front side of the housing, a movable ring slidably connected to the inner wall of the rear side of the housing, a fixed block fixedly connected to the outer wall of the right end of the movable ring, a long rod threaded through and connected to the inner wall of the movable ring, a movable rod slidably connected to the inner wall of the long rod, a limiting component provided on the inner wall of the bottom end of the housing for fixing the fixed block, and an elastic component provided on the inner wall of the long rod for moving the movable rod.

[0007] As a further description of the above technical solution:

[0008] The elastic component includes a limiting plate, the front end of which is elastically connected to the inner wall of the long rod by a spring.

[0009] As a further description of the above technical solution:

[0010] The limiting component includes an insert, the upper outer wall of which is elastically connected to the lower inner wall of the housing by a spring.

[0011] As a further description of the above technical solution:

[0012] One end of the spring is fixedly connected to the inner wall of the long rod, and the other end of the spring is fixedly connected to the outer wall of the front end of the limiting plate.

[0013] As a further description of the above technical solution:

[0014] The inner wall of the limiting plate is fixedly connected to the outer wall of the moving rod, and the outer wall of the limiting plate is slidably connected to the inner wall of the long rod.

[0015] As a further description of the above technical solution:

[0016] One end of the second spring is fixedly connected to the inner wall of the bottom end of the housing, and the other end of the second spring is fixedly connected to the outer wall of the upper end of the insert.

[0017] As a further description of the above technical solution:

[0018] The rear sidewall of the insert is inclined, the upper outer wall of the insert is slidably connected to the bottom inner wall of the housing, and the lower outer wall of the insert is engaged with the inner wall of the fixing block.

[0019] As a further description of the above technical solution:

[0020] A membrane-breaking needle is detachably installed on the inner wall of the front end of the movable rod.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by pushing the fixing block forward, the movement of the fixing block drives the moving ring and the long rod to move forward, so that the long rod extends into the birth canal opening. The fixing block squeezes the insert and causes it to retract to the inner wall of the shell. When the limiting groove inside the fixing block moves to the lower end of the insert, the insert pops out and snaps into the inner wall of the fixing block to fix the fixing block. The position of the long rod can be quickly adjusted, and then the long rod can be rotated to make slow adjustments, which can save the time for the rupture needle to move to the amniotic fluid membrane.

[0023] 2. In this utility model, by pushing the moving rod forward, the limiting plate moves forward to squeeze the spring, causing the rupture needle to extend out of the long rod and puncture the amniotic membrane. Then, the moving rod is released, and the elastic force of the spring causes the limiting plate to move the moving rod backward, causing the rupture needle to retract to the inner wall of the front end of the long rod. This can realize the retraction of the rupture needle and avoid accidental needle puncture of pregnant women or medical staff. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3This utility model provides an embodiment of an artificial membrane rupture device for obstetrics and gynecology, comprising a housing 1. A collar is provided on the outer wall of the housing 1 for stable gripping by the user. The interior of the housing 1 is hollow, providing protection for the front outer wall of a long rod 2. A fixing ring 7 is fixedly connected to the inner front wall of the housing 1, providing support for the sliding of the long rod 2. A movable ring 8 is slidably connected to the inner front wall of the housing 1, moving synchronously with the movement of a fixing block 9. The position of the movable ring 8 is fixed by fixing the fixing block 9. The movement of the movable ring 8 drives the movement of the long rod 2. The right end of the movable ring 8... A fixing block 9 is fixedly connected to the wall. The fixing block 9 slides on the housing 1 to drive the movement of the moving ring 8. A long rod 2 is threaded through and connected to the inner wall of the moving ring 8. The outer wall of the front end of the long rod 2 is arc-shaped to avoid injury to the human body when it extends. A moving rod 4 is slidably connected to the inner wall of the long rod 2. The moving rod 4 is used to install the membrane rupture needle. The membrane rupture needle is detachably installed on the inner wall of the front end of the moving rod 4. A limit component is provided on the inner wall of the bottom end of the housing 1. The limit component is used to fix the fixing block 9. The movement of the fixing block 9 can drive the movement of the moving ring 8. An elastic component is provided on the inner wall of the long rod 2. The elastic component is used to move the moving rod 4.

[0032] Reference Figure 1 and Figure 2 The elastic component includes a limiting plate 6, which limits the movement of the moving rod 4 to prevent rotation during movement. When the moving rod 4 moves forward, it drives the limiting plate 6 forward to compress the spring 5, causing the rupture needle to extend out of the long rod 2 and releasing the moving rod 4. The elastic force of the spring 5 causes the limiting plate 6 to move backward. The inner wall of the limiting plate 6 is fixedly connected to the outer wall of the moving rod 4, and the outer wall of the limiting plate 6 is slidably connected to the inner wall of the long rod 2. The front end of the limiting plate 6 is elastically connected to the inner wall of the long rod 2 through the spring 5. One end of the spring 5 is fixedly connected to the inner wall of the long rod 2, and the other end of the spring 5 is fixedly connected to the front outer wall of the limiting plate 6.

[0033] Reference Figure 3 and Figure 4 The limiting component includes an insert 3, which is used to fix the fixing block 9. When the outer wall of the front end of the fixing block 9 presses against the inclined surface of the insert 3, the insert 3 is compressed and retracts upward to the inner wall of the housing 1. When the limiting groove inside the fixing block 9 moves to the lower end of the insert 3, the insert 3 pops out and engages with the inner wall of the fixing block 9 by the elastic force of the second spring 10. The rear side wall of the insert 3 is inclined. The upper outer wall of the insert 3 is slidably connected to the bottom inner wall of the housing 1. The lower outer wall of the insert 3 is engaged with the inner wall of the fixing block 9. The upper outer wall of the insert 3 is elastically connected to the bottom inner wall of the housing 1 by the second spring 10. One end of the second spring 10 is fixedly connected to the bottom inner wall of the housing 1, and the other end of the second spring 10 is fixedly connected to the upper outer wall of the insert 3.

[0034] Working principle: By inserting a finger into the collar to grasp the amniotic rupture device, and pushing the fixed block 9 forward, the movement of the fixed block 9 drives the moving ring 8 and the long rod 2 forward, allowing the long rod 2 to extend into the birth canal. The outer wall of the front end of the fixed block 9 presses against the inclined surface of the insert 3, causing the insert 3 to retract upwards onto the inner wall of the housing 1. Once the inner limiting groove of the fixed block 9 moves to the lower end of the insert 3, the insert 3 pops out and engages with the inner wall of the fixed block 9 under the elastic force of the second spring 10, fixing the fixed block 9 and fixing the position of the moving ring 8. Then, by rotating the long rod 2, the long rod 2 is slowly moved forward. After the outer wall of the front end of the long rod 2 contacts the amniotic membrane, pushing the moving rod 4 forward drives the limiting plate 6 forward, pressing the first spring 5, causing the rupture needle to extend out of the long rod 2 and rupture the amniotic membrane. Then, the moving rod 4 is released, and the elastic force of the first spring 5 causes the limiting plate 6 to move the moving rod 4 backward, causing the rupture needle to retract back to the inner wall of the front end of the long rod 2, completing the rupture operation.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
