It is inside provided with piston, the end of piston is connected with push rod, runs through on push rod along the central axes of push rod and offer threaded hole, threaded hole
It is inside bolted with membrane puncture needle adjusting rod, one end of the membrane puncture needle adjusting rod far from piston is exceptionally exposed to outside sleeve, and exposes to sleeve
It is provided with graduation mark on outer membrane puncture needle adjusting rod, is opened up on piston by there is circular hole, membrane puncture needle installation is slidably fitted in circular hole
Seat, the membrane puncture needle mounting base and membrane puncture needle adjusting rod are integrally formed, and are equipped with membrane puncture needle in the membrane puncture needle mounting base, described
Threaded hole, circular hole and membrane puncture needle perforation three's coaxial line.
Preferably, membrane puncture needle perforation is other to be symmetrically arranged with mounting hole, headlamp, mounting hole are installed in the mounting hole
On glass lamp shade is installed.
Preferably, integrally formed with drainage device on the sleeve.
Preferably, the drainage device includes being integrally formed and sleeve outer wall and the drainage tube that communicates with sleeve inner
And it is bolted in the drainage bottle on drainage tube.
Compared with prior art, the beneficial effects of the present invention are:
The configuration of the present invention is simple, design rationally, the telescopic distance of membrane puncture needle are accurately controlled by using the mode that screw thread is adjusted
From, and the extended length for reacting membrane puncture needle is understood by the scale on threaded rod, it is convenient for the accurate rupture of membranes of doctor, and complete rupture of membranes
Afterwards, membrane puncture needle is retracted in circular hole, avoids membrane puncture needle secondary injury, while headlamp is set by membrane puncture needle perforation, just
Rupture of membranes situation is observed when operation.

Specific embodiment
The present invention is further illustrated with attached drawing combined with specific embodiments below.
Embodiment one
As shown in Figure 1, a kind of membrane rupturing device used in obstetrics, including sleeve 1, the left and right ends of sleeve 1 are open setting, sleeve 1
Front inner wall integrally formed with baffle 2, baffle 2 is arc-shaped, and the membrane puncture needle perforation being machined on baffle 2 through baffle 23 and is drawn
Fluid apertures 4, membrane puncture needle perforation 3 are located at the center of baffle 2, and guiding fluid hole 4 is distributed on baffle 2, and piston 5 is provided in sleeve 1, living
Plug 5 is connected with push rod 6 backwards to one end of baffle 2, runs through on push rod 6 along the central axes of push rod 6 and offers threaded hole 7, threaded hole 7
It is inside bolted with membrane puncture needle adjusting rod 8, one end of the membrane puncture needle adjusting rod 8 far from piston 5 is exceptionally exposed to outside sleeve 1, and is exposed to
Graduation mark 9 is machined on membrane puncture needle adjusting rod 8 outside sleeve 1,5 center of piston is machined with the circular hole 10 through piston 5, circular hole 10
It is inside slidably fitted with membrane puncture needle mounting base 11, membrane puncture needle mounting base 11 is bonded with the inner wall of circular hole 10, and membrane puncture needle mounting base 11
