Description

Technical Field

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

[0002] Some pregnant women require induced labor due to special circumstances. A routine procedure includes artificial rupture of membranes (APRM), which involves a doctor manually puncturing the amniotic sac covering the fetus during labor to allow amniotic fluid to flow out, thus accelerating or inducing the labor process. This procedure requires the doctor to puncture the amniotic sac through the cervix within the narrow vagina. Typically, the doctor relies on experience and touch, using their index and middle fingers to hold the needle of a 5mL syringe to perform this operation. However, because the needle is short and the exposed tip lacks protection, this manual procedure is difficult, and injuries to the operator's fingers or failed rupture are frequent occurrences. Furthermore, the depth of insertion cannot be guaranteed. Utility Model Content

Through the setting of a limiting component, the insertion distance of the needle can be limited, preventing harm to the mother and fetus. Simultaneously, the needle remains within the receiving slot throughout its insertion, preventing scratches to the cervix. Through the setting of a fixing component, a suitable needle can be quickly clamped and used for membrane rupture based on the actual situation of the mother and fetus.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an obstetric artificial membrane rupture needle, characterized in that it comprises:

Detailed Implementation

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] This application provides an artificial membrane rupture needle for obstetric use, which can achieve (the first beneficial effect listed) the following detailed description of the artificial membrane rupture needle. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0024] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] Please see Figure 1-5 This embodiment provides an obstetric artificial membrane rupture needle, characterized in that it includes: a cylindrical body 1, with a receiving groove 102 and a moving groove 103 inside the cylindrical body 1, a needle 6 inside the receiving groove 102, and a connecting rod 3 inside the moving groove 103; a limiting component disposed between the cylindrical body 1 and the connecting rod 3, the limiting component including: a limiting groove 4, a limiting hole 401, and a limiting rod 403; and a fixing component disposed between the needle 6 and the connecting rod 3, the fixing component including: a moving plate 5, a connecting block 501, a slot 502, a mounting block 601, and a spring piece 603, an anti-slip sleeve 101 fixedly connected to the outside of the cylindrical body 1, and a threaded cap 2 threadedly connected to one end of the cylindrical body 1.

[0027] By setting the threaded cap 2, the internal space of the storage slot 102 can be sealed to prevent the storage slot 102 from being contaminated and causing the needle 6 to be infected. Then, by setting the anti-slip sleeve 101, it can be ensured that the doctor can hold the cylinder 1 stably to perform surgical operations.

[0028] The limiting component limits the insertion distance of the needle 6, preventing it from harming the mother and fetus. The needle 6 remains in the storage slot 102 throughout its insertion, preventing it from scratching the inside of the cervix. The fixing component allows for quick clamping of a suitable needle 6 to perform the membrane rupture operation based on the actual situation of the mother and fetus.

[0029] Example 2

[0030] Based on Embodiment 1, a limiting groove 4 is provided on one side of the cylinder 1, and multiple limiting holes 401 are provided on the surface of the cylinder 1. The multiple limiting holes 401 are evenly arranged in a horizontal direction and are connected to the limiting groove 4. A threaded rod 402 is provided inside the limiting hole 401. A push plate 301 is fixedly connected to one end of the connecting rod 3. A limiting rod 403 is provided inside the limiting groove 4, and one end of the limiting rod 403 is connected to the push plate 301.

[0031] During the membrane rupture process, to avoid excessive insertion depth of the needle 6 and potential damage to the mother or fetus, the maximum extension distance of the needle 6 needs to be limited. At this time, the threaded rod 402 can be removed from the limiting hole 401, and then, according to the required extension length, the threaded rod 402 can be inserted into the corresponding limiting hole 401. This allows the doctor to insert the cylinder 1 into the mother's body during the procedure, while the needle 6 remains in the receiving groove 102, preventing the needle 6 from scratching the mother during insertion. After the cylinder 1 reaches the designated position, the push plate 301 pushes the connecting rod 3 and the needle 6 to move, causing the needle 6 to move out of the receiving groove 102 for the membrane rupture procedure. During the movement of the push plate 301, the limiting rod 403 moves within the limiting groove 4 and contacts the threaded rod 402, thus limiting the maximum movement distance of the needle 6, the push plate 301, and the connecting rod 3.

[0032] Example 3

[0033] Based on Embodiment 1, the storage slot 102 is connected to the moving slot 103. One end of the connecting rod 3 extends into the storage slot 102. One end of the connecting rod 3 is fixedly connected to the moving plate 5. One side of the moving plate 5 is fixedly connected to the connecting block 501. A slot 502 is opened on the outer side of the connecting block 501. One end of the needle 6 is fixedly connected to the mounting block 601. One side of the mounting block 601 is opened to the mounting slot 602, and the mounting slot 602 matches the size of the connecting block 501. Multiple spring pieces 603 are fixedly connected inside the mounting slot 602.

[0034] During artificial rupture of membranes, different needle lengths and thicknesses are required depending on the different positions of the mother and fetus. For example, short needles are suitable for cases where the vagina is shallow or a smaller penetration depth is required. This type of needle can reduce the risk of damage to surrounding tissues. If the fetus is in a higher position or the mother's pelvic structure is special, a longer needle may be required. A finer needle can reduce the size of the puncture point, which helps to reduce the risk of infection and is more suitable for some more sensitive tissue areas. When there is too much amniotic fluid or when it is necessary to release amniotic fluid more quickly, a slightly thicker needle may be selected to ensure rapid and effective rupture of membranes.

[0035] Therefore, before surgery, the connecting block 501 on the moving plate 5 can be pushed out of the storage slot 102. Then, a suitable needle 6 can be picked up with sterilized tweezers and moved to the connecting block 501, so that the mounting slot 602 corresponds to the position of the connecting block 501. Then, the mounting block 601 is brought closer to the connecting block 501. At this time, the spring 603 is deformed by the pressure of the connecting block 501. After the connecting block 501 is fully inserted into the mounting slot 602, the spring 603 corresponds to the position of the slot 502 and rebounds, so that the spring 603 and the slot 502 are locked together, thereby fixing the needle 6. Then the needle 6 can be put back into the storage slot 102, completing the instrument preparation work before surgery.
