AI Technical Summary
Technical Problem
Existing traditional membrane rupture tools lack precise depth control mechanisms, which can lead to excessively deep insertion, increasing the risk of fetal injury, and also result in poor operational stability.
Method used
It employs a threaded engagement mechanism between a rotating handle and an advance rod, combined with an arc-shaped amniotic rupture needle and a transparent collection box, to achieve precise control of insertion depth and stable operation. It is also equipped with a scale for easy monitoring of amniotic fluid.
Benefits of technology
It improves the safety and accuracy of the amniotic fluid rupture process, reduces the risk of fetal injury, enhances operational stability, and provides a convenient means of amniotic fluid monitoring.

Abstract
The utility model relates to the technical field of medical instruments, in particular to a fetal membrane puncturing device for gynaecology and obstetrics, which comprises a connecting handle, the front end of the connecting handle is rotatably connected with a rotating handle, a pushing rod is arranged in the connecting handle in a sliding and penetrating mode, one end of the pushing rod extends into the rotating handle, and an external thread is arranged on the surface of the end portion of the pushing rod. And an internal thread matched with the rotating handle is arranged in the rotating handle. By adding a thread matching mechanism of the rotating handle and the pushing rod, accurate control over the feeding amount and the puncturing depth of the membrane rupturing needle is achieved, the risk caused by too deep puncturing to a fetus is reduced, the stability and accuracy of operation are remarkably improved, the uncertainty caused by manual operation is reduced, and therefore the safety of the membrane rupturing process is improved.
