Abstract
The utility model relates to a medical gynecologic operating instrument, in particular to a gynecologic operating air bag cervical dilator. The duct interface of the air bag cervical dilator is communicated with a baseball-shaped dilation bar through the duct; air holes for communicating inside and outside of the dilation bar are arranged in the wall of the dilation bar, and the dilation bar is enwrapped by a membrane air bag. The utility model which is simple in structure, low in cost and easy in manufacture not only simplifies the structure of a prior cervical dilator to reduce operation sequence but also retains the advantage of gradual and continuous dilation of a prior hydraulic pressure cervical dilator to alleviate pains of patients suffering from operation. Moreover, continuity of aseptic manipulation is guaranteed and uterine cavity infection is prevented.
Description
Technical field:
This utility model relates to hospital's gynecologic operating instruments, relates in particular to a kind of air bag cervical dilator that is used for gynecilogical operation.
Background technology:
The uterus cervical dilator that prior art adopts when termination of pregnancy is done artificial miscarriage or done diagnostic curettage is made up of one group of different round metal bar of thickness.Use Shi doctor to have only, could enlarge cervix uteri gradually pole repeatedly inserting successively in patient's the cervix uteri from fine to coarse.Circle metal bar dilator simple in structure operate also uncomplicatedly, but to bigger by the stimulation of operator, easily causes the uterine cavity infection simultaneously.The hydraulic pressure cervical dilator has then alleviated by the stimulation of operator, but need join liquid and the corresponding apparatus that transmits expansionary force in addition, increases associated auxiliary operation, therefore uses also to be restricted.
Summary of the invention:
The purpose of this utility model is intended to overcome the deficiencies in the prior art, provides a kind of simple in structure, is easy to make, and is easy to operate, greatly alleviates by the stimulation of operator, prevents the air bag cervical dilator that causes cervix uteri to infect simultaneously.
The technical solution of the utility model is:
The catheter interface of this air bag cervical dilator by conduit be excellent spheric dilator bar and be communicated with, have on the dilator bar wall and link up the inside and outside passage of dilator bar, the outside of dilator bar is with the thin film air bag.
This utility model is simple in structure, with low cost, be easy to make, simplify the structure of cervix dilating apparatus, reduced operation sequence, kept the advantage of the continuous expansion of hydraulic dilatation cervix uteri device gradual change of prior art simultaneously again, alleviated the misery the when patient is performed the operation, in addition, can guarantee the seriality of aseptic technique, prevent to cause uterine cavity to infect.
Description of drawings:
Accompanying drawing is the structural representation of this utility model embodiment.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
The catheter interface 5 of this air bag cervical dilator is communicated with by the dilator bar 2 that conduit 4 and front end are bat shape, described dilator bar 2 adopts the most small size cervical dilator bar that is using at present, the outer thin film air bags 1 that are with of dilator bar 2 are being provided with the different directions of linking up inside and outside the dilator bar and the passage 3 of position on the dilator bar 2.
This utility model adopts the most small size cervical dilator bar that is using at present, and before unaerated, the thin film air bag is close on the dilator bar, and external diameter is very thin.During use, the catheter interface of afterbody knot syringe is inwardly inflated with syringe, and syringe seals simultaneously, the chap of inflation rear film airbag inflation, and during operation, other are discharged by the contraction of thin film air bag, and the thin film air bag is close on the dilator bar, then extracts.
Claims (1)
1, a kind of air bag cervical dilator is characterized in that: catheter interface (5) is communicated with the dilator bar that is bat shape (2) by conduit (4), and the dilator bar wall is provided with the inside and outside passage (3) that connects, and is with thin film air bag (1) outside dilator bar.
