Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of obstetrics film breaking unit.
Background technology
Rupture of membranes is operation commonly used in the obstetrics, rupture of membranes instrument commonly used is puncture needle and vascular forceps in the hospital at present, very inconvenient when operating with the puncture needle doctor, than higher, and the degree of depth is difficult for grasping when puncturing fetal membrane to doctor's requirement, thrusts the degree of depth and crosses deeply and may damage fetus, puncture needle causes damage to vagina during by vagina easily, dangerous, vascular forceps then is difficult for clipping broken fetal membrane, and operation easier is bigger.
Summary of the invention
Technical assignment of the present utility model is at the deficiencies in the prior art, and a kind of reasonable in design, obstetrics' film breaking unit that result of use is good is provided.
The technical scheme that its technical problem that solves this utility model adopts is:
A kind of obstetrics film breaking unit, comprise sleeve pipe, be provided with funnel and be connected with its bottom at an end of sleeve pipe, the sleeve pipe other end is provided with rotary switch and hinged with it, inside pipe casing near funnel is provided with puncture needle and sliding seat, and the puncture needle rear end is arranged in sliding seat one side and with it fixedlys connected, and is provided with screw rod in the sleeve pipe of sliding seat opposite side, screw rod one end penetrates sliding seat and is threaded with it, and the other end is fixedlyed connected with aforementioned rotary switch.
A kind of obstetrics film breaking unit, its described sliding seat is provided with through hole.
Obstetrics of the present utility model film breaking unit compared with prior art, the beneficial effect that produces is:
The utlity model has characteristics such as reasonable in design, simple in structure, easy to use, practicality, puncture needle is arranged in the sleeve pipe, can make vagina avoid being subjected to puncture needle to injure, can control preferably by rotary switch and to thrust the degree of depth, injured fetus deeply in order to avoid in operation process, thrust, funnel can make fetal membrane and bell mouth be close to, and by funnel and cover Tube Drain, prevents that fetal membrane from puncturing flow through cervical canal and injury of birth canal face of afterwaters and causing amniotic embolism; Because described sleeve pipe is transparent casing, can better hold in the operation and thrust the degree of depth.
Description of drawings
Accompanying drawing 1 is front portion structure sketch map of the present utility model.
Among the figure: 1, rotary switch, 2, sleeve pipe, 3, screw rod, 4, sliding seat, 5, through hole, 6, puncture needle, 7, funnel.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is done following detailed description the in detail.
As shown in drawings, obstetrics of the present utility model film breaking unit, its structure comprises sleeve pipe 2, be provided with funnel 7 and be connected with its bottom at an end of sleeve pipe 2, sleeve pipe 2 other ends are provided with rotary switch 1 and hinged with it, sleeve pipe 2 inside near funnel 7 are provided with puncture needle 6 and sliding seat 4, puncture needle 7 rear ends are arranged in sliding seat 4 one sides and with it fixedlys connected, be provided with screw rod 3 in the sleeve pipe 2 of sliding seat 4 opposite sides, screw rod 3 one ends penetrate sliding seat 4 and are threaded with it, the other end is fixedlyed connected with aforementioned rotary switch 1, and described sliding seat 4 is provided with through hole 5.
During use, funnel 7 is attached on the fetal membrane, rotate rotary switch 1, make screw rod 3 promote sliding seat 4 thereby change, sliding seat 4 promotes puncture needle 6 and punctures fetal membrane, funnel 7 can be close to fetal membrane, by funnel 7 and sleeve pipe 2 drains, prevents that fetal membrane from puncturing flow through cervical canal and injury of birth canal face of afterwaters and causing amniotic embolism.
Obstetrics of the present utility model its processing and fabricating of film breaking unit is simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except the described technical characterictic of description, be those skilled in the art's known technology.
