The invention discloses a gynecological and obstetrical membrane rupturing device and a use method thereof, and belongs to the field of gynecological and obstetrical medical instruments. The problem that due to the existing membrane rupturing technology, operation is complex, infection is likely to be caused, and the operation environment is poor is solved. The gynecological and obstetrical membrane rupturing device comprises a membrane rupturing barrel and a supporting base. The membrane rupturing barrel comprises a barrel body, a movable plate, a piston and a connecting rod, a fixed plate and the movable plate are arranged at the front end in the barrel body, the surfaces of the fixed plate and the movable plate adhere, and the fixed plate and the movable plate are rotationally connected. A membrane rupturing needle is arranged on a needle containing groove of the fixed plate, the piston stretches into the membrane rupturing barrel from the bottom of the barrel body, and the supporting base comprises a base and a supporting frame. The supporting frame comprises a bottom face, a telescopic rod and an arc-shaped concave support detachably connected with the membrane rupturing barrel, and a third sliding channel, a fourth sliding channel and the telescopic rod on the supporting frame provide a proper position adjusting mode for the membrane rupturing barrel. A needle returning groove of the movable plate can effectively retract the needle, and the movable plate and the fixed plate rotate to achieve membrane rupturing and cavity sealing operation. According to the device, fast membrane rupturing can be effectively achieved, and it is avoided that amniotic fluid flows out to cause infection.
