Abstract
The utility model relates to a cervical dilator, which comprises a parent dilation section and a sub dilation section. The utility model is characterized in that the sub dilation section is arranged in the parent dilation section, and two elastic soft jackets are covered outside the parent dilation section and the sub dilation section.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically cervical dilator.
Background technology
At present, hospital is when having a manual miscarriage operation to the women, and employed cervical dilator divides a plurality of models by diameter, in to the cervical dilatation process, need ascending frequent replacing model, do like this that not only operation link is many, and cause certain misery to patient.
Summary of the invention
Technical assignment of the present utility model is at above weak point, provide a kind of simple in structure, be easy to process, safe and reliable cervical dilator.
The technical scheme that its technical problem that solves the utility model adopts is: this expander comprises female expansion section and sub-expansion section, and sub-expansion section is arranged in female expansion section, female expansion section and the flexible soft sheath of sub-expansion section overcoat.
Sub-expansion section and female expansion section are slided and are joined; Be provided with 2-4 sub-expansion section in female expansion section, sub-expansion section diameter reduces successively, and slip is joined each other; Sub-expansion section length is longer than female expansion section length, and the length between the sub-expansion section increases gradually with reduced; The sub-expansion section front end of diameter minimum is slick and sly head.
During use, with the son expansion joint insertion women cervix uteri mouth place of diameter minimum, after a period of time, draw back minimum son expansion joint earlier, insert the slightly expansion joint of any of diameter forward, change successively, to the last the cervix uteri mouth is expanded to requiring till the size.Because female expansion section and the flexible soft sheath of sub-expansion section overcoat when changing expansion section, can not hurt patient's uterine mucosa, avoid postoperative to cause stifled the staying of menses that cervical adhesion causes.
Cervical dilator of the present utility model is compared with prior art, have reasonable in design, simple in structure, easy to use, be easy to processing, characteristics such as safe and reliable.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further specified.
Accompanying drawing is the structural representation of cervical dilator.
Among the figure: 1, soft sheath, 2, female expansion section, 3, sub-expansion section, 4, slick and sly head.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to restriction of the present utility model.
Cervical dilator of the present utility model, its structure comprise female expansion section 2 and sub-expansion section 3, and sub-expansion section 3 is arranged in female expansion section 2, the flexible soft sheath 1 of female expansion section 2 and sub-expansion section 3 overcoats.
Its processing and fabricating of cervical dilator of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of description, be the known technology of those skilled in the art.
