Abstract
The utility model relates to a membrane rupturing needle for gynaecology and obstetrics. The membrane rupturing needle for the gynaecology and the obstetrics comprises a guide tube and a needle core, wherein the needle core is sleeved in the guide tube, and a trumpet-shaped sucking disc is arranged at the front end of the guide tube. Semi-circular-ring-shaped grasping parts are symmetrically arranged on outer walls of two sides of the rear end of the guide tube. An annular or hooked push-pull part is arranged at the tail end of the needle core, and the front end of the needle core is of a needle tip shape. The membrane rupturing needle for the gynaecology and the obstetrics is simple in structure, convenient and safe to use and high in accuracy. Due to the fact that the trumpet-shaped sucking disc is arranged at the front end of the guide tube, the stability is strong. Unnecessary damages produced by membrane rupturing are reduced, and pain of a puerpera is relieved. The cross infection is prevented from being caused, and the working difficulty of doctors in the gynaecology and the obstetrics is relieved.
Description
Technical field:
This utility model relates to a kind of medical instruments, is specifically related to a kind of obstetrics and gynecology department rupture of membranes pin.
Background technology:
At present, in clinical department of obstetrics and gynecology, the puerpera of rupture of membranes automatically when producing adopts rupture of membranes to clamp more or mosquito forceps comes rupture of membranes, and the safety of rupture of membranes is relatively poor, if amniotic fluid of pregnant woman is few, clamps fetal scalp easily, damages to fetus.If amniotic fluid of pregnant woman is many, during with rupture of membranes pincers or mosquito forceps rupture of membranes, the fetal membrane damaged area is big, very easily causes amniotic fluid to flow out in a large number, easily causes to infect and cause placental abruption and prolapse of cord, increases trouble and misery for anemia of pregnant woman and fetus.
The utility model content:
The technical problems to be solved in the utility model is the above-mentioned deficiency at prior art, provides a kind of simple in structure, easy to operate, and can reduce infection, safe and reliable obstetrics and gynecology department rupture of membranes pin.
For solving the problems of the technologies described above, this utility model adopts following technical scheme:
A kind of obstetrics and gynecology department rupture of membranes pin, comprise conduit and nook closing member, nook closing member is sleeved in the conduit, the front end of conduit is provided with trumpet-shaped sucker, the holding part that is provided with semi-annular shape of symmetry on both sides, the rear end outer wall of conduit, the tail end of nook closing member is provided with ring-type or hook-shaped push-and-pull parts, and the front end of nook closing member is tip-like.
Described nook closing member is made by rustless steel or medical plastic.
Described conduit is made by transparent medical plastic.
The beneficial effects of the utility model are: this utility model is simple in structure, safety easy to use, the accuracy height, because catheter proximal end is provided with trumpet-shaped sucker, its stability is strong, reduces the unnecessary damage that rupture of membranes produces, and has reduced puerpera's misery, avoid causing cross infection, alleviated gynecologist's work difficulty.
Description of drawings:
The structural representation of Fig. 1 this utility model embodiment.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
A kind of obstetrics and gynecology department rupture of membranes pin of the present utility model, comprise conduit 1 and nook closing member 3, nook closing member 3 is sleeved in the conduit 1, the front end of conduit 1 is provided with trumpet-shaped sucker 5, the holding part that is provided with semi-annular shape 2 of symmetry on both sides, the rear end outer wall of conduit 1, the tail end of nook closing member 3 is provided with ring-type or hook-shaped push-and-pull parts 4, and the front end of nook closing member 3 is tip-like, and nook closing member 3 is made by rustless steel or medical plastic.Conduit 1 is made by transparent medical plastic.
During childbirth, operator with thumbstall in the push-and-pull parts 4 of nook closing member 3 tail ends, two holding parts 2 that refer to clamp on the conduit 1 promote nook closing member 3 needle point are pushed into the position equal with the front end of conduit 1 in the right hand food, and the horn mouth of conduit 1 front end is attached to vaginal orifice, pin the front end of conduit 1 with two fingers in the left hand food, promote needle point and go deep into intravaginal, needle point withstands the proamnion capsule, and hand thumb is pushed ahead, amniotic fluid is arranged when horn mouth flows out, withdraw from the rupture of membranes pin and get final product.
