Abstract
The utility model discloses an obstetric membrane rupturing device, including the first dactylotheca of cover on the forefinger and the second dactylotheca of cover on the middle finger, the root of first dactylotheca and second dactylotheca is all connected in the basement, is provided with the sleeve pipe between first dactylotheca and second dactylotheca, and at the intraductal pjncture needle that is provided with of cover, the end of fixed of pjncture needle is provided with the slide rail with sliding block matched with on set inside pipe wall on the sliding block, and the sliding block is connected with the worm, is provided with the gyro wheel with worm engaged with in the basement. The utility model discloses find rupture of membranes point more easily than other apparatuses, moreover the utility model discloses a regulation roller promotes the pjncture needle and punctures the fetal membrane, and the degree of depth is mastered than easy, and just the accuracy was high by force for convenient to use, safety and sanitation, stability when medical staff carried out artifical rupture of membranes, had alleviateed medical staff's the work degree of difficulty.
Description
Technical field
This utility model relates to a kind of obstetrics medical apparatus and instruments, specifically relates to a kind of obstetrics film breaking unit.
Background technology
Artificial rupture of membrane and artificial mode intervention tear uteri position amniotic membrane, to observe amniotic fluid color, reinforcement uterine contraction, acceleration progress of labor, are a kind of induced labor modes comparatively common in spontaneous labor process.At present, the clinical apparatus being most commonly used to this operation is puncture needle, concrete operation method is: probe into vagina with two or three fingerhold syringe needles, finger stereognosis is relied on to judge the correct position that rupture of membranes punctures and opportunity, then make needle tip come out from the finger tip closed up, gently find fault with needle point and wear the object that amniotic membrane reaches rupture of membranes.Existing puncture needle structure is simple, higher to the skill requirement of doctor during operation, and when puncturing fetal membrane, the degree of depth is not easily grasped.
Utility model content
The purpose of this utility model is to provide a kind of obstetrics film breaking unit.
The technical solution that this utility model adopts is:
A kind of obstetrics film breaking unit, comprise the first fingerstall be enclosed within forefinger and the second fingerstall be enclosed within middle finger, the root of the first fingerstall and the second fingerstall is all connected in substrate, sleeve pipe is provided with between the first fingerstall and the second fingerstall, in sleeve pipe, be provided with puncture needle, the tail end of puncture needle is fixed on sliding shoe, and internal surface of sleeve pipe is provided with the slide rail matched with sliding shoe, sliding shoe is connected with worm screw, and substrate is provided with the roller be meshed with worm screw.
Preferably, the tail end of described puncture needle is provided with rubber bulb, and described sliding shoe is provided with draw-in groove, and rubber bulb snaps in draw-in groove.
Preferably, described sleeve pipe and the second fingerstall bond together, and the length of sleeve pipe is less than the second fingerstall.
Advantageous Effects of the present utility model is:
(1) the first fingerstall and the second fingerstall are enclosed within forefinger and middle finger by this utility model respectively, when finger closes up, puncture needle is positioned in the middle of two fingerstall, can safety put into birth canal, the stereognosis ability of finger is relied on more easily to find rupture of membranes point compared with other apparatuses, and this utility model promotes spike pierces fetal membrane by regulating roller, the degree of depth is more easily grasped, health easy to use, safe when medical worker carries out artificial rupture of membrane, stability is strong and accuracy is high, alleviates the work difficulty of medical worker.
(2) this utility model is provided with rubber bulb at the tail end of puncture needle, snaps in sliding shoe draw-in groove by rubber bulb, realizes puncture needle and is connected with the detachable of sliding shoe, changes after facilitating puncture needle to use.
(3) sleeve pipe and the second fingerstall bond together by this utility model, prevent sleeve pipe from misplacing, and add the accuracy of rupture of membranes operation.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 illustrates the concrete annexation of the parts such as puncture needle in this utility model.
Detailed description of the invention
By reference to the accompanying drawings, a kind of obstetrics film breaking unit, the root that the length comprising the first fingerstall 1 be enclosed within forefinger and the second fingerstall 2, first fingerstall 1 be enclosed within middle finger is less than the second fingerstall 2, first fingerstall 1 and the second fingerstall 2 is all connected in substrate 3.Sleeve pipe 4 is provided with between the first fingerstall 1 and the second fingerstall 2, sleeve pipe 4 is in elongated cylindrical, in sleeve pipe 4, be provided with puncture needle 5 along its length, the tail end of puncture needle 5 is fixed on sliding shoe 6, and sleeve pipe 4 inwall is provided with the slide rail 7 matched with sliding shoe 6.Sliding shoe 6 is connected with one end of worm screw 8, and substrate 3 is provided with the roller 9 be meshed with worm screw 8.
Work process of the present utility model is roughly as follows: be worn on forefinger by the first fingerstall 1 cover, second fingerstall 2 cover is worn on middle finger, when two fingers close up, puncture needle 5 is positioned in the middle of two fingerstall, can safety put into birth canal, after finding rupture of membranes point, worm screw 7 moving linearly can be driven by jog dial 8, and then promotion puncture needle 5 punctures fetal membrane.
As to further improvement of the utility model, the tail end of described puncture needle 5 is provided with rubber bulb 10, and described sliding shoe 6 is provided with draw-in groove, and rubber bulb 10 snaps in draw-in groove.Puncture needle 5 can be realized be connected with the fractionation of sliding shoe 6 by arranging above, facilitate puncture needle 5 to use rear replacing.
Further, described sleeve pipe 4 and the second fingerstall 2 bond together, and the length of sleeve pipe 4 is less than the second fingerstall 2.This setting can effectively prevent sleeve pipe 4 from misplacing, and adds the accuracy of rupture of membranes operation.
It should be noted that; above-described embodiment is only for illustration of this utility model; and do not lie in the restriction scope of application of the present utility model; after reading this utility model; any equivalents done by various equivalent modifications; or obvious variant, all should in protection domain of the present utility model.
