Description
Technical field
The present invention relates to obstetrics' technical field, especially a kind of suction tire formula obstetric apparatus.
Background technique
Vacuum extractor and obstetric forceps are common obstetric apparatus；Vacuum extractor has that rigidity is poor, and when delivery of fetus is difficult to
Make the deficiency of delivery of baby by rotating；Although obstetric forceps rigidity is preferably, make delivery of baby conducive to by rotation, existing easily makes
Fetus is damaged deficiency；Therefore, delivery of baby can be made by rotation when designing a kind of delivery of fetus, fetus is not easily vulnerable
Tire formula obstetric apparatus is inhaled, urgent problem to be solved is become.
Summary of the invention
Poor the purpose of the invention is to overcome current vacuum extractor to there is rigidity, when delivery of fetus, is difficult to pass through
Rotation makes the deficiency of delivery of baby；Although obstetric forceps rigidity is preferably, make delivery of baby conducive to by rotation, existing easily makes fetus
Be damaged deficiency, can make delivery of baby by rotation when providing a kind of delivery of fetus, the not easily vulnerable suction tire formula of fetus helps
Produce device.
The specific technical solution of the present invention is:
A kind of suction tire formula obstetric apparatus, comprising: the handle tube there are two handle is set, equipped with the negative pressure sucker being connected to handle pipe orifice
And the sucker connecting with handle tube lower end, the rotation auxiliary device on the outside of sucker, the negative pressure set on handle tube upper end are adjusted
Device.The suction tire formula obstetric apparatus is in use, the inner hole of regulation pipe is connected to negative pressure device is taken out；When childbirth, sucker is in negative pressure
The head that fetus is sucked under effect carries out midwifery；It is adjustable negative pressure by rotating negative pressure adjusting device, to be made with the smallest suction
Delivery of baby；Handle is pulled, handle tube drives sucker rotation, makes the synchronous rotation in top and bottom of sucker by rotating auxiliary device
Turn, so that fetus is smoothly given birth to and fetus not subject to damage by rotation.
Preferably, the rotation auxiliary device includes: to connect with side wall outside sucker coaxial arrangement and upper end and handle tube
The protective plate connect, several between protective plate and sucker and circumferential chain group, be set to the outer side wall of handle tube and
With the annular groove of handle tube lower end perforation, be set in annular groove and with several one-to-one engaging lug groups of chain group；Chain group packet
Several circumferential chains are included, engaging lug group includes number engaging lug pair identical and one-to-one with chain number；
The axis direction of the articulated shaft of chain is the normal direction of the distribution circle where chain；The upper end of chain is located at two companies of engaging lug pair
It is between lug and hinged by pin shaft and engaging lug；The lower end of protective plate envelopes chain lower end and connect with sucker lower end.By
The normal direction for being distributed circle where the axis direction of the articulated shaft of the chain of rotation auxiliary device is chain, both made sucker in negative pressure
The lower head that fetus can swimmingly be sucked of effect carries out midwifery, and since chain is not easy lateral bending, torque is transmitted through chain, and makes to inhale
It the top and bottom of disk can synchronous rotary.
Preferably, there are three the chain groups；One chain group is located at the rear side of sucker, and another two chain group is one by one
The corresponding outside for being located at sucker two sides；Two handles correspond the two sides for being located at handle tube.When childbirth, doctor knows tire with feel
The preceding face position of youngster, a chain group is opposite with the rear portion of fetal head, another two chain group respectively with the left and right sides of fetal head
Relatively, make fetal head uniform force when driving sucker rotation conducive to hand pipe.
Preferably, the rotation auxiliary device includes: to connect with side wall outside sucker coaxial arrangement and upper end and handle tube
The protective plate connect, several are set to the outer side wall of handle tube between protective plate and sucker and circumferential arc strip group
Lower part and with several one-to-one groups of slots of arc strip group；Arc strip group includes several circumferential arc strips,
Groups of slots includes number slot identical and one-to-one with arc strip number；The width of arc strip is the octuple to 16 of thickness
Times, the width direction of arc strip is the normal direction of the distribution circle where arc strip；The width of arc strip is adapted to the width of slot, and
In the upper end insertion slot of arc strip；The lower end of protective plate envelopes arc strip lower end and connect with sucker lower end.Due to rotation
The thinner thickness of the arc strip of auxiliary device and the width direction of arc strip are the normal direction of the distribution circle where arc strip, both make to inhale
The head that fetus can be swimmingly sucked in disk under the action of negative pressure carries out midwifery；And since arc strip is not easy lateral bending, torque is through arc
Item transmitting, and make the top and bottom synchronous rotary of sucker.
Preferably, there are three the arc strip groups；One arc strip group is located at the rear side of sucker, another two arc strip
Group corresponds the outside for being located at sucker two sides；Two handles correspond the two sides for being located at handle tube.
When childbirth, doctor knows the preceding face position of fetus with feel, and an arc strip group is opposite with the rear portion of fetal head, another two
A arc strip group is opposite with the left and right sides of fetal head respectively, makes fetal head uniform force when driving sucker rotation conducive to hand pipe.
Preferably, the negative pressure adjusting device includes: that side wall lower part is equipped with several circumferential adjustment holes
And the regulation pipe being connect with handle tube upper end, it is sheathed on the adjusting set that outside regulation pipe and internal diameter is adapted to adjusting pipe outside diameter；It adjusts
The cross-sectional shape in hole is the isosceles triangle that apex angle is located at lower end；Upper part is equipped with external screw thread on the outside of regulation pipe；In adjusting set
