Abstract

The invention discloses a membrane breaker for obstetrics and gynecology, which relates to the technical field of medical devices; it solves many problems existing in breaking the membrane with a needle; it specifically includes a bottom plate, the top outer wall of the bottom plate is fixedly connected with a lifting assembly, and the top outer wall of the lifting assembly is fixedly connected There is a propulsion component, the top outer wall of the propulsion component is fixedly connected with a connecting component, and the outer wall of one side of the connecting component is fixedly connected with a ruptured membrane component. In the present invention, a membrane-breaking component is arranged, wherein the two core rods rotate forward, the arc edge of the blade cuts the amniotic membrane, and at the same time, the four blades move together to form a wound on the surface of the amniotic fluid with the same diameter as the cutter head, and the two core rods reverse Turn, the right-angled edge of the blade hooks the surface of the amniotic fluid to wrap and tear, thereby expanding the wound surface, and pulling at the same time reduces the volume of the amniotic fluid and accelerates the discharge of amniotic fluid; It can take into account the dual functions of opening and extrusion drainage.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a membrane rupturer for obstetrics and gynecology. Background technique [0002] At present, most membrane rupturers use the needle puncture method, but the needle puncture method has the following problems. First, the feeding distance of the needle needs to be highly controllable, because the position of the fetus in the amniotic fluid environment is uncertain, and other Second, the opening area that can be formed by the needle is small, which makes it difficult to quickly empty the amniotic fluid. Third, once the opening is found to be small, the membrane must be ruptured again. The difficulty of breaking the membrane. [0003] After searching, the Chinese patent application number is 201710454159.4, which discloses a membrane disruptor for obstetrics and gynecology, which includes a vertically arranged cylinder with openings at both ends. The membrane breaking needle...
