It is built-in with opening up horn-like sucker, the small end perforation of the sucker, which is connected with, to be sequentially passed through knife rest bottom and push rod and prolong
The suction pipe outside push rod lower end surface is extended to, the lower end oral area of the suction pipe is connected with suction capsule.A kind of obstetrics of the present invention are with safety-type
Amnion film breaking unit inhales capsule and suction pipe to drive sucker suction amnion, between increasing between amnion and fetus by manipulation
Gap, and certain fixed function to amnion is played by adsorption capacity, it can be conducive in this way by pushing with swivelling tool-holder come fast
Speed punctures amnion, and avoids the damage to fetus.
Preferably, being provided with limit stop ring on the outer tube wall, being provided on the push rod can match with limit stop ring
The circular baffle plate of conjunction, the circular baffle plate are located on the downside of limit stop ring, convenient for control knife rest extreme position, avoid the damage to fetus
Wound.
Preferably, the circular baffle plate downside on the push rod is provided with resetting spring, the push rod lower end is provided with hand
Handle is convenient to operation.
Preferably, the multiple bayonet is uniformly distributed in a ring, convenient for quickly puncturing amnion.
Preferably, the working face of the bayonet is triangular shape, it is highly 0.5-1 millimeters, amnion can be punctured and protected
Protect fetus.
Preferably, the bayonet is threadedly coupled with knife rest, it is conveniently replaceable and assembles.
Preferably, the outer tube top, which is provided with private parts, struts circle, it is convenient for surgical procedure.
It is made using flexiplast or rubber material preferably, the private parts struts circle, can avoid that private parts is caused to damage
Wound.
Preferably, the private parts struts outer diameter of the outer diameter more than outer tube of circle, it is convenient for surgical procedure.
Preferably, the sucker is made using flexiplast or rubber material, it is ensured that its adsorption capacity.
Compared with prior art, a kind of advantageous effect of the safety-type amnion film breaking unit of obstetrics of the present invention：Pass through design
Rational amnion adsorbs and fixes and punctures structure, and realization rupture of membranes that not only can be rapidly and efficiently operates, but also can be to the maximum extent
The damage caused by fetus is avoided, there is very strong practicability.
