Technical field
The utility model is related to a kind of obstetrics' membrane puncture needle, belongs to Medical instruments Appliances technical field.
Background technology
At present, obstetrics there is no special equipment when carrying out artificial rupture of membrane, need to be used according to the custom of every obstetrician
Syringe needle or vessel forceps are carried out.When syringe needle is used for artificial rupture of membrane, syringe needle need to be clamped in food, middle interphalangeal and enter vagina, and its stability is poor,
Accuracy is not high, can not then be operated when palace mouthful is less than 3 centimetres；When vessel forceps are used for artificial rupture of membrane, because vessel forceps are long
Degree is limited, and pincers top is more blunt, need to clamp fetal membrane and tear, so uncontrollable cut size, one-time success rate is low, to medical worker
Add great work difficulty.
The patent of Patent No. 201320087847.9 discloses a kind of obstetrics' membrane puncture needle, including body, it is characterized in that
The front end of body, which is provided with sucker, sucker, is provided with membrane puncture needle, and the rear end of body is provided with piston, and piston is provided with pull handle.Though its
Easy to use, stability is strong, alleviates the work difficulty of medical worker, but it haves the shortcomings that very big, is on the one hand difficult to control
The size of the dynamics of entrance, easily causes pain；On the other hand when not in use, naked expose outside of syringe needle easily causes infection or touched
Bad, so as to have to what is renewed again, cost is larger.
Utility model content
The technical problems to be solved in the utility model is：The deficiencies in the prior art are overcome there is provided one kind is simple in construction, it is painful
Small and syringe needle not easy infection or the obstetrics' membrane puncture needle broken.
The utility model solves the technical scheme that its technical problem used：Obstetrics' membrane puncture needle, it is characterised in that：Bag
Include syringe and sucker, sucker, which is detachably connected in syringe lower end, syringe, is provided with piston, piston by pull bar and syringe outside
Handle be fixedly connected, syringe bottom, which is provided with inside some pin holes, syringe between pin hole and piston, is provided with dials, dials lower end
Provided with some needle bodies corresponding with pin hole.
It is preferred that, described syringe outer wall upper end is provided with graduation mark, and the dynamics of handle is pressed according to scale line traffic control, so that
The pain of patient can effectively be mitigated.
It is preferred that, described sucker is threadedly coupled with syringe.
It is preferred that, described dials is provided with some needle trays, and needle body is detachably connected with needle tray, is easy to clean and changes bad
The needle body fallen.
It is preferred that, described handle side is provided with lighting apparatus, and lighting apparatus is electrically connected with the battery on the inside of handle, can be with
Sufficient light is provided, unnecessary surgical errors are reduced.
It is preferred that, described lighting apparatus is LED.
It is preferred that, described handle presses switch, lighting apparatus is shinny provided with switch when using, save the energy.
It is preferred that, described handle is ellipse, is adapted with the man-computer cooperation of human thumb, uses comfort and convenient.
Compared with prior art, the utility model is had an advantageous effect in that：
1st, dials is located inside syringe, when not in use draw back dials in syringe, has been subtracted needle body infection and has been broken
Drawback.
2nd, syringe outer wall upper end is provided with graduation mark, the dynamics of handle is pressed according to scale line traffic control, so as to effectively subtract
The pain of hypopathia people.
3rd, unnecessary surgical errors are reduced in handle side provided with lighting apparatus there is provided sufficient light.
4th, dials is provided with some needle trays, and needle body is detachably connected with needle tray, is easy to clean and changes the needle body that breaks down, into
This is low, easy to utilize.
