Abstract
The utility model discloses an obstetrical membrane rupture needle, which comprises a needle body. An operating rod is arranged on the periphery of the needle body, a connecting seat is arranged between the needle body and the operating rod, external threads are arranged at the front end and the rear end of the connecting seat, internal thread holes matched with the external threads are arranged at two ends of the operating rod, a central groove is arranged at the rear end of the operating rod, and the central line of the needle body is overlapped with that of each internal thread hole. The obstetrical membrane rupture needle is simple in structure, convenient in operation, fine in stability, high in accuracy and high in success rate, the size of a rupture opening is easily controlled, and the needle body can be stored in the central groove when not in use so that the obstetrical membrane rupture needle is portable, clean and hygienic.
Description
Technical field
This utility model relates to technical field of medical instruments, and especially a kind of obstetrics use the rupture of membranes pin.
Background technology
At present, clinical obstetrics does not still have special equipment when carrying out artificial rupture of membrane; Need custom, use syringe needle or vascular forceps to carry out its poor stability when syringe needle is used for artificial rupture of membrane according to every obstetrician; Accuracy is not high; Then can't operate during in 3 centimetres when the palace is young, the vascular forceps one-time success rate is low, brings many difficulties for obstetrician's operation.
The utility model content
The purpose of this utility model is to provide a kind of good stability and the high obstetrics of accuracy to use the rupture of membranes pin for addressing the above problem.
The technical scheme that this utility model technical solution problem adopts is: a kind of obstetrics use the rupture of membranes pin; Comprise needle body; The outer periphery of said needle body is equipped with action bars, is provided with Connection Block between needle body and the action bars, and the rear and front end of Connection Block is provided with external screw thread; The two ends of action bars are provided with the internal thread hole that is used with external screw thread, and the rear end of action bars is provided with central channel.
The central lines of said needle body and internal thread hole.
The two sides up and down of said action bars are respectively arranged with hand-held ring, and said hand-held ring is about the centrage symmetry of internal thread hole.
The beneficial effect that this utility model had is:
This utility model is simple in structure, and is easy to operate, good stability, and accuracy is high, controls the cut size easily, and success rate is high, can needle body be accommodated in the central channel when not using, and is easy to carry, clean hygiene.
Description of drawings
Accompanying drawing is the structural representation of this utility model.
