Fig. 1 is the structural representation of this utility model embodiment;
Fig. 2 is the structural representation that this utility model embodiment handle 4 folds.
Detailed description of the invention
With reference to the accompanying drawings detailed description of the invention of the present utility model is made a detailed explanation below.
According to shown in Fig. 1 to Fig. 2, a kind of cervical dilator, comprise interconnective expansion successively 1, extending frame 2, connecting rod 3 and two side handles 4, described expansion 1 rear end is connected with described extending frame 2, expansion 1 and extending frame 2 are circular hollow structure, extending frame 2 comprises top sector 6, bottom sector 7 and monosymmetric expanding plate 8, the upper end of top sector 6 is provided with two symmetrical fulcrums 9 that are fixedly hinged, the lower end of top sector 6 is provided with two and symmetrical is movably hinged fulcrum 10, the upper end of bottom sector 7 is provided with two and symmetrical is movably hinged fulcrum 10, the lower end of bottom sector 7 is provided with two symmetrical fulcrums 9 that are fixedly hinged, described expanding plate 8 is half arcuate structure, the fulcrum 10 that is movably hinged being movably hinged fulcrum 10 and bottom sector 7 of the top sector 6 of side is connected on this side expanding plate 8, the fulcrum 10 that is movably hinged being movably hinged fulcrum 10 and bottom sector 7 of the top sector 6 of opposite side is connected on opposite side expanding plate 8, the upper end of top sector 6 is provided with activity adjustment face 11, activity adjustment face 11 is flexible material, activity adjustment face 11 is connected with the fulcrum 9 that is fixedly hinged at top sector 6 two ends, the both sides, lower end of extending frame 2 are connected to connecting rod 3, what connecting rod 3 was connected to bottom sector 7 is fixedly hinged on fulcrum 9, connecting rod 3 connects described handle 4 respectively, handle 4 is equipped with press strip 12, two lateral layering 12 symmetries are interconnected to intermediate, inclined and are connected with an inner core 13 in junction, inner core 13 is in described expansion 1 and described extending frame 2, the other end head of inner core 1 is provided with pusher head 14.The pusher head 14 of described inner core is connected with the centre point in activity adjustment face 11 all the time, and the expanding plate 8 described in two panels folds the outer ring of outer ring together and described extending frame 2 on same arcwall face.
Top sector 6 and bottom sector 7 respectively with the unfolding mode that be fixedly hinged fulcrum 9 and the connected mode that is movably hinged fulcrum 10 are existing umbrella or tent, be prior art, both sides outer edge one circle of expanding plate 8 is integuments of soft material, the outer ring that integument is only wrapped in single expanding plate 8 is not respectively interconnected, integument connects top sector 6 and bottom sector 7, also there is the protective layer of soft material the outer ring of top sector 6 and bottom sector 7, the centre of top sector 6 and bottom sector 7 has the broken line of gathering respectively gatherings many for flexibility material interior under rounding state, and the integument of both sides is drawn close mutually, under open mode, top sector 6 and bottom sector 7 are strutted completely, and as the state that tent or umbrella class are opened, and the integument of centre separates, the space communicated before and after intermediate formation one.
In use, first handle 4 is in separated position, and now the pusher head 14 of inner core 13 withstands on the centre point in activity adjustment face 11, and activity adjustment face 11 is states of an almost level.When dilator is inserted in cervix uteri, because described expansion 1 front end is provided with arc protection 5, so cervix uteri can not cause damage, more described expansion 1 external diameter is less than the external diameter of described extending frame 2, so just achieves primary expansion.When extending frame 2 is in cervix uteri inner wall outside, hands executes pressurized handgrip 4, and handle 4 folds, and press strip 12 is tightened up, and inner core 13 is by pull backward.Because the pusher head 14 of inner core 13 front end is connected with activity adjustment face 11 all the time, a little distortion can be caused for flexible material in activity adjustment face 11, but what simultaneously active force had acted on the top sector 6 being connected to both sides, activity adjustment face 11 is fixedly hinged on fulcrum 9, the fulcrum 9 that is fixedly hinged conduction gives and is movably hinged fulcrum 10, be movably hinged fulcrum 10 to be subject to power and outwards to strut, owing to being unconnected between two expanding plates 8, what two expanding plates 8 were connected to again both sides is movably hinged on fulcrum 10, so power allows expanding plate 8 strut to both sides, driven bottom sector 7 to be movably hinged fulcrum 10 stressed, until upper and lower two are movably hinged fulcrum 10 on same lateral surface.Inwall due to cervix uteri is the expansible of softness, and the power receiving expanding plate 8 will be compressed, and cervix uteri has just been easily inserted into the expanded.When needing dilator to regain, directly extract also passable, if but inserted dark, the inwall of cervix uteri head is not expanded, and directly extracts and can cause damage, so first will regain the outer ring of extending frame.Now only need to unclamp hands, the inwall of such cervix uteri has had the expanding plate 8 of necessarily a small amount of force compresses both sides, firmly strut laterally again, inner core 13 driven forward, due to the effect of restoring force, inner core 13 can exceed the centre point of certain force activity compression adjusting range 11, activity adjustment face 11 power is upwards allowed to conduct to the fulcrum 9 that is fixedly hinged of both sides like this, the fulcrum 9 that is fixedly hinged gives power conduction and is movably hinged fulcrum 10, coordinate both sides expanding plate 8 by the power of cervix uteri inwall again, be movably hinged fulcrum 10 and start inside recovery, the inner side returning to two panels expanding plate 8 connects, expanding plate 8 folds the outer ring of outer ring together and extending frame 2 on same arcwall face, now handle 4 is in separated position again, this completes a cervical dilatation.
