Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to an artificial membrane rupture device. Background Art
[0002] In obstetrics and gynecology, the amniotic fluid capsule will rupture naturally before delivery, allowing the amniotic fluid to flow out, so that the fetus can be delivered smoothly. When the woman's uterine contraction is insufficient, the pelvic shape is abnormal, the fetus is too large or the posture is abnormal, etc., which lead to difficult delivery, midwifery may be necessary. The doctor will use an artificial rupture device to rupture the amniotic fluid sac, reduce the pressure on the head, and help the fetus pass through the birth canal. The artificial rupture device is generally used for midwifery and delivery. It can rupture the membrane to allow the amniotic fluid to flow out, reduce the difficulty of delivery, and make it easier for the child to pass through the birth canal. The following problems exist in the existing technology:
[0003] The traditional artificial rupture device is a curved tool that doctors use to puncture the amniotic sac through the birth canal, thereby breaking the membrane and allowing the amniotic fluid to flow out, reducing the difficulty of delivery. However, due to the different thicknesses of the actual amniotic sac, sharp or blunt tools are often prepared during the operation to make it easier to puncture the amniotic sac. However, preparing multiple rupture devices to replace operations in different situations increases the number of surgical instruments and wastes time. Obviously, this needs to be improved in the time-sensitive fetal delivery environment.
[0004] Based on this, an artificial membrane rupture device is proposed. Utility Model Content

Under the premise of giving priority to ensuring safety during surgery, a blunt membrane rupture end can be selected. If the membrane rupture fails, the pointed membrane rupture end can be quickly replaced, saving surgical instruments and facilitating operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In the present embodiment, when the artificial rupture device is used to rupture membranes, the insertion mechanism 1 is first inserted into the birth canal of the parturient through one end of the conical head 13. The left end of the conical head 13 has a larger diameter than the right end, which is convenient for insertion into the birth canal of the parturient and enhances passability. The columnar insertion body 12 is relatively smooth, which reduces the discomfort of the parturient during insertion. After insertion, the operating port 11, whose left end has a larger diameter than the right end, will be exposed outside the parturient's body, making it convenient for the doctor to insert relevant medical devices into the parturient's body through the insertion mechanism 1 for operation.
[0027] like Figure 4 As shown, the utility model provides a technical solution: preferably, the elastic mechanism 2 includes a support plate 23, the left end of the support plate 23 is fixedly connected with an arc-shaped elastic plate 21, the outer surface of the support plate 23 is sleeved with an anti-slip sleeve 22, and the right end of the support plate 23 is provided with a mounting opening 24, the elastic mechanism 2 is fixedly clamped on the inner wall of the insertion mechanism 1 through the arc-shaped elastic plate 21, and the elastic mechanism 2 is installed with the membrane breaking mechanism 3 through the mounting opening 24.
[0028] In this embodiment, the membrane rupture mechanism 3 is installed at the right end of the elastic mechanism 2. The elastic mechanism 2 is clamped in the installation groove 14 opened on the inner wall of the top of the left end of the insertion mechanism 1 through the arc-shaped elastic plate 21. Then, by moving the support plate 23, one end of the membrane rupture mechanism 3 at the right end can be moved, thereby puncturing the amniotic fluid membrane. The anti-slip sleeve 22 plays an anti-slip role to prevent the doctor from slipping during operation. After the elastic mechanism 2 is installed, the doctor can operate it with one hand, which makes it easy to operate in a relatively narrow birth canal operating space.
[0029] like Figure 5 As shown, the utility model provides a technical solution: preferably, the membrane rupturing mechanism 3 includes a membrane rupturer 34, the left end of the membrane rupturer 34 is fixedly connected with a blunt membrane rupturer end 32, the right end of the membrane rupturer 34 is fixedly connected with a sharp membrane rupturer end 35, the middle part of the membrane rupturer 34 is rotatably plugged with a plug-in column 31, the bottom of the plug-in column 31 is fixedly installed with a screw rod 36, the bottom of the plug-in column 31 passes through the elastic mechanism 2 and the membrane rupturer 34 and is threadedly installed with a nut 33, and the membrane rupturer 3 is installed on the elastic mechanism 2 through the plug-in column 31.
[0030] In this embodiment, due to the different thicknesses of the actual amniotic sac, traditional artificial rupture of membranes is often prepared with a sharp or blunt tip to make it easier to puncture the amniotic sac. The membrane rupture mechanism 3 of the artificial membrane rupture device has a quick replacement mechanism. After the membrane rupture mechanism 3 is installed in the insertion mechanism 1 through the elastic mechanism 2, the right end is exposed from the right end of the insertion mechanism 1. By loosening the nut 33 threadedly installed at the bottom of the plug-in column 31, the connection between the membrane rupture device 34 and the support plate 23 is loosened, so that the membrane rupture device 34 can be rotated to replace the original blunt membrane rupture end 32 at one end with a sharper pointed membrane rupture end 35. Under the premise of ensuring safety first during surgery, the blunt membrane rupture end 32 can be selected. If the membrane rupture fails, the pointed membrane rupture end 35 can be quickly replaced, saving surgical instruments and facilitating operation.
[0031] The working principle of the artificial membrane rupture device is described in detail below.
[0032] like Figure 1-5 As shown, when the artificial membrane rupture device is used to rupture membranes, the insertion mechanism 1 is first inserted into the birth canal of the parturient through one end of the conical head 13. The left end diameter of the conical head 13 is larger than the right end, which is convenient for insertion into the birth canal of the parturient and enhances passability. The columnar insertion body 12 is relatively smooth, which reduces the discomfort of the parturient during insertion. After insertion, the operating port 11 with a left end diameter larger than the right end will be exposed outside the parturient's body, which is convenient for the doctor to insert relevant medical equipment into the parturient's body through the insertion mechanism 1 for operation. The membrane rupture mechanism 3 is installed at the right end of the elastic mechanism 2. The elastic mechanism 2 is clamped in the installation groove 14 on the inner wall of the top of the left end of the insertion mechanism 1 through the arc-shaped elastic plate 21. Then, by toggling the support plate 23, one end of the membrane rupture mechanism 3 at the right end can be moved, thereby puncturing the amniotic fluid film. The anti-slip sleeve 22 plays an anti-slip role to prevent the hand from slipping during operation. The elastic mechanism 2 is installed After installation, the doctor can operate it with one hand, which makes it easy to operate in a relatively narrow birth canal operating space. Due to the different thicknesses of the actual amniotic sac, traditional artificial rupture of membranes often prepares sharp or blunt ones to make it easier to puncture the amniotic sac. The membrane rupture mechanism 3 of the artificial membrane rupture device has a quick replacement mechanism. After the membrane rupture mechanism 3 is installed in the insertion mechanism 1 through the elastic mechanism 2, the right end is exposed from the right end of the insertion mechanism 1. By loosening the nut 33 threadedly installed at the bottom of the plug-in column 31, the connection between the membrane rupture device 34 and the support plate 23 is loosened, so that the membrane rupture device 34 can be rotated to replace the original blunt membrane rupture end 32 at one end with a sharper pointed membrane rupture end 35. Under the premise of giving priority to ensuring safety during surgery, the blunt membrane rupture end 32 can be selected. If the membrane rupture fails, the pointed membrane rupture end 35 can be quickly replaced, saving surgical instruments and facilitating operation.
