The content of the invention
The present invention provides a kind of obstetrics membrane breaking device, to solve defect of the prior art.
The present invention is achieved by the following technical programs:
Obstetrics membrane breaking device, including sleeve, the front end of sleeve is provided with two arc strips, and one end and the sleeve of arc strip are hinged, arc Be provided with torsion spring at the jointed shaft of bar and sleeve, the two ends of torsion spring connect arc strip and sleeve respectively, torsion spring all the time to arc strip to The power opened outside;One end of the other end connecting stay wire of arc strip, the other end of bracing wire is located at the rear end of sleeve, the rear end of sleeve Provided with end cap, open up through hole on end cap, through a screw rod in through hole, coordinate on screw rod and be provided with nut, the other end of bracing wire with Nut is connected, and nut is located at the outside of end cap;It is provided with sleeve in several bearing fixed seats, sleeve and is provided with rotating bar, rotating bar It is connected by bearing and bearing fixed seat;Cutter head is installed in the front end of rotating bar, and cutter head is located at the front end of sleeve;Rotating bar Rear portion periphery, which is provided with external screw thread, the external screw thread of rotating bar to coordinate, is provided with swivel nut, and poke rod, the side of sleeve are installed in the outside of swivel nut Wall opens up through groove, and poke rod passes through through groove.
Obstetrics membrane breaking device as described above, the leading inside of described sleeve is provided with directive wheel, and bracing wire coordinates with directive wheel, The inside of sleeve is provided with several guide sleeves, is drawstring through guide sleeve.
It is an advantage of the invention that:In the present invention, adjusting nut makes two arc strips closure, point diameter of the invention compared with It is small, it can easily be inserted into the birth canal of puerpera, behind in-position, by adjusting nut, screw rod be extended inwardly into, in torsion spring In the presence of arc strip open be attached on amniotic fluid film.Poke rod is now stirred, poke rod is moved along through groove, swivel nut is moved in the lump Dynamic, under threaded function, rotating bar is rotated, so as to be scratched amniotic fluid film by the cutter head of end, completes rupture of membranes.The present invention It can prevent from scratching fetus during rupture of membranes, while convenient pass in and out in puerpera's birth canal.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing There is the accompanying drawing used required in technology description to be briefly described, it should be apparent that, drawings in the following description are this hairs Some bright embodiments, for those of ordinary skill in the art, without having to pay creative labor, can be with Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the present invention;Fig. 2 is Fig. 1 A direction views.
Reference:The bearing of 1 sleeve, 2 arc strip, 3 torsion spring, 4 bracing wire, 5 end cap, 6 through hole, 7 screw rod, 8 nut 9 is fixed The guide sleeve of 16 directive wheel of seat 10 rotating bar, 11 bearing, 12 cutter head, 13 swivel nut, 14 poke rod, 15 through groove 17.
Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is A part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
Obstetrics membrane breaking device, as illustrated, including sleeve 1, the front end of sleeve 1 is provided with two arc strips 2, the one of arc strip 2 End is hinged with sleeve 1, is provided with torsion spring 3 at the jointed shaft of arc strip 2 and sleeve 1, the two ends of torsion spring 3 connect respectively arc strip 2 and Sleeve 1, torsion spring 3 gives the outward power of arc strip 2 all the time;One end of the other end connecting stay wire 4 of arc strip 2, bracing wire 4 it is another One end is located at the rear end of sleeve 1, and the rear end of sleeve 1, which is provided with end cap 5, end cap 5, opens up through hole 6, through a screw rod in through hole 6 7, coordinate on screw rod 7 and be provided with nut 8, the other end of bracing wire 4 is connected with nut 8, nut 8 is positioned at the outside of end cap 5;In sleeve 1 Provided with several bearing fixed seats 9, rotating bar 10 is provided with sleeve 1, rotating bar 10 is coordinated by bearing 11 and bearing fixed seat 9 and connected Connect;Cutter head 12 is installed in the front end of rotating bar 10, and cutter head 12 is located at the front end of sleeve 1;The rear portion periphery of rotating bar 10 is provided with outer spiral shell Coordinate on line, the external screw thread of rotating bar 10 and be provided with swivel nut 13, poke rod 14 is installed in the outside of swivel nut 13, and the side wall of sleeve 1 is opened up Through groove 15, poke rod 14 passes through through groove 15.In the present invention, adjusting nut 8 closes two arc strips 2, and front end of the invention is straight Footpath is smaller, easily can be inserted into the birth canal of puerpera, behind in-position, and by adjusting nut 8, screw rod 7 is extended inwardly into, Arc strip 2 is opened and is attached on amniotic fluid film in the presence of torsion spring 3.Poke rod 14 is now stirred, poke rod 14 is moved along through groove 15 Dynamic, swivel nut 13 is moved in the lump, under threaded function, and rotating bar 10 is rotated, so as to by the cutter head 12 of end by amniotic fluid film Scratch, complete rupture of membranes.The present invention can prevent from scratching fetus during rupture of membranes, while convenient pass in and out in puerpera's birth canal.
