Abstract
The utility model relates to an obstetric film breaking device, which comprises a cannula and a puncture needle, wherein a hopper is arranged at the front end of the cannula; the puncture needle is arranged in the cannula; the film breaking device is provided with a gear rack device; a stripped groove is formed at the tail end of the cannula; scales are formed beside the stripped groove; a mark is arranged at a position which corresponds to the stripped groove on the puncture needle; the gear rack device comprises a rack arranged on the puncture needle, and a gear fixed on the cannula; a part of the gear is exposed out of the cannula; and the gear rack device is provided with a limiting device. After the adoption of the structure, the puncture needle is pushed forwards through the gear rack device, so that only one hand is needed for operating during use; the scales are formed at the tail end of the film braking device, so that greater convenience is brought to observation; and the tail end of the film breaking device provided with the scales can be taken as an operating handle.
Description
Technical field
This utility model relates to a kind of obstetrics medical apparatus and instruments, relates in particular to a kind of obstetrics' membrane-repturing device that comprises sleeve pipe.
Background technology
Artificial rupture of membrane is to be used for one of medical intervention means commonly used that promote stages of labor in the obstetrics.At present, the clinical apparatus that is most commonly used to this operation is puncture needle, concrete operation method is: probe into vagina with two or three fingerhold syringe needles, rely on the finger stereognosis to judge correct position and the opportunity of rupture of membranes puncture, the syringe needle front end is come out from the finger tip that closes up, gently find fault with needle point and wear the purpose that amniotic membrane has reached rupture of membranes.In addition, use mosquito forceps to probe into vagina in addition, thereby tear amniotic membrane and realize rupture of membranes by pinching folder.Yet, no matter be to carry out the artificial rupture of membrane operation with puncture needle or with mosquito forceps, in actual mechanical process, often there are disadvantage and hidden danger: use syringe needle to carry out the rupture of membranes operation, experience to the doctor is had relatively high expectations, and the degree of depth is difficult for grasping when puncturing fetal membrane, thrusts too deeply and may hurt fetus; Mosquito forceps then is difficult for clipping broken fetal membrane, and operation easier is bigger.
Some obstetrics' membrane-repturing devices of safety have also appearred at present.China utility model prospectus CN201987641U discloses a kind of obstetrics membrane-repturing device, comprises sleeve pipe, is provided with puncture needle in the sleeve pipe, the sleeve pipe other end is provided with screw feeding mechanism, puncture needle pushes forward by screw feeding mechanism, can control preferably to thrust the degree of depth, avoids hurting the baby.But, use screw feeding mechanism to need a hand-held membrane-repturing device, the peaceful bolt of turn-knob must be operated by two handss simultaneously on the other hand, and is very inconvenient.
The utility model content
The purpose of this utility model provides a kind of safe obstetrics' membrane-repturing device, and this obstetrics' membrane-repturing device only needs a hands just to be convenient to operation.
For solving the problems of the technologies described above, obstetrics of the present utility model membrane-repturing device comprises sleeve pipe and puncture needle, and the sleeve pipe front end is provided with funnel, and puncture needle is arranged in the sleeve pipe, and the rack-and-pinion device is set on the membrane-repturing device.
Described sleeve pipe tail end has a strip groove, and strip groove next door is provided with scale, is provided with labelling with strip groove relevant position on the described puncture needle.
Described rack-and-pinion device comprises the tooth bar that is arranged on the puncture needle and the gear that is fixed on the sleeve pipe, and the part of described gear is exposed outside the sleeve pipe.
Described rack-and-pinion device is provided with stopping means.
After adopting such structure, because puncture needle pushes ahead by the rack-and-pinion device, only need a hands to operate during use, scale is arranged on the membrane-repturing device tail end, more convenient observation, the handle when the membrane-repturing device tail end that has a scale also can be used as operation
Description of drawings
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.
Fig. 1 is the structural representation of this utility model obstetrics membrane-repturing device.
Fig. 2 be among the membrane-repturing device Fig. 1 of this utility model obstetrics A part along vertical part sectioned view of I-I line.
The specific embodiment
Obstetrics of the present utility model membrane-repturing device comprises sleeve pipe 1 and puncture needle 2 as shown in Figure 1, and sleeve pipe 1 front end is provided with funnel 3, and puncture needle 2 is arranged in the sleeve pipe 1, and puncture needle 3 is to push ahead by rack-and-pinion device 4.Sleeve pipe 1 tail end has a strip groove 5, and strip groove 5 next doors are provided with scale 6, is provided with labelling 7 with strip groove 5 relevant positions on the puncture needle 2.As shown in Figure 2, rack-and-pinion device 4 comprises the tooth bar 8 that is arranged on the puncture needle 2 and the gear 9 that is fixed on the sleeve pipe 1, and the part of gear 9 is exposed sleeve pipe outer 1.Rack-and-pinion device 4 is provided with stopping means 10.
During use, hold the membrane-repturing device tail end, funnel 3 is attached on the fetal membrane, thumb wheel gear 9 promotes tooth bar 8 forward, punctures fetal membrane thereby promote puncture needle 2, can observe the degree of depth that puncture needle 2 advances by the labelling 7 on the puncture needle 2 and the scale 6 on the sleeve pipe 1.
