Description
Technical field
The present invention relates to a kind of cervical dilatation technology, in particular to a kind of telescopic cervical dilator bar and application method.
Background technique
Cervical dilatation is artificial abortion in gynecology operation (just stopping the main means of unscheduled pregnancy at present), is placed or taken out in utero
The steps necessary of contraceptive, the preoperative gynecological surgery for needing cervix dilating.Cervical dilator bar is currently used for the main of cervical dilatation
Instrument.When carrying out cervical dilatation, different diameter specifications (φ 4.0mm, 6.0 7.0 mm of mm, φ of 5.0 φ mm, φ) are utilized
Cervical dilator bar, diameter are sequentially inserted into uterine neck from small to large and are expanded.The shortcomings that this expansion method, is: operating process compared with
To be cumbersome, and in process of expansion, need the expansion metal stick of multiple and different diameter specifications being sequentially inserted into uterine neck, expand
Uterus neck is easy to happen the adverse reactions such as infection, allergy, pain discomfort in journey.
Such as: China Patent Publication No. CN201005766, a kind of entitled cervical dilator bar of utility model, structure
It is provided with hollow connecting tube including handle and dilator bar, between handle and dilator bar, dynamics induction number is provided in connecting tube
According to processor, digital display screen is provided with right above connecting tube.Operating process is relatively complicated when in use for the utility model,
And in process of expansion, the cervical dilator bar by multiple and different diameter specifications is needed to be sequentially inserted into uterine neck, uterine neck in process of expansion
Position is easy to happen the adverse reactions such as infection, allergy, pain discomfort.
Summary of the invention
Present invention aim to address traditional cervical dilator bars when carrying out cervical dilatation, needs using multiple and different straight
The problem of cervical dilator bar of diameter specification is sequentially inserted into uterine neck and is expanded, and uterus neck is easy to happen infection in process of expansion,
A kind of telescopic cervical dilator bar and application method are provided, can be effectively reduced the risk of cervical infection.
The purpose of the present invention is what is be achieved through the following technical solutions: a kind of telescopic cervical dilator bar, including center is expanded
Stick, be socketed on central extension stick with the level-one dilator bar of central extension stick relative movement, be socketed on level-one dilator bar with
