Ring instrument is got by a kind of gynecological
Technical field
The present invention relates to a kind of medical apparatus and instruments, specifically, relate to a kind of gynecological and get ring instrument.
Background technology
At present, the contraceptive device of China to married woman at reproduction age mainly contains barrier contraception, medical contraception, natural family planning etc., and wherein intrauterine device (IUD) is safer, more convenient contraceptive device widely.Intrauterine device is the annular (also known as intrauterine contraceptive loop, intrauterine device) made with materials such as rustless steel, plastics or silicone rubber, T-shaped, the Y type etc. of band copper, and the main anti-fertilization of its effect also stops germ cell implantation, thus reaches the object of contraception.Permanently effective after placing, need can take out and not affect fertility during gestation.Intrauterine contraceptive loop clinically need be generally Hook for removal of intrauterine device with apparatus when taking out, namely intrauterine is stretched into by cervix uteri, take out intrauterine contraceptive loop, but this to get ring mode one-time success rate low, often to again and again get several times, inefficiency, and careless slightly Hook for removal of intrauterine device may injure uterus inwall, thus person brings larger misery to being got ring.
In addition, some intrauterine contraceptive loops are due to the time longer distortion of band or incarceration, or because of other reason, when getting ring, very pain, needs to carry out anesthesia and palliate the agonizing sufferings, and anesthesia needs special apparatus, makes whole ring process of getting become complicated; According to clinical investigation, the women of most band, there is difference in uterus.
Summary of the invention
The technical problem to be solved in the present invention overcomes above-mentioned defect, provide a kind of easy to use, one-time success rate is high, not easily injure the gynecological of vaginal walls gets ring instrument.
For solving the problem, the technical solution adopted in the present invention is:
Ring instrument is got by a kind of gynecological, and comprise tubular shell, described shell one end is provided with ring flange, and the other end is hemispherical configuration, and centre is provided with gets annular distance, it is characterized in that: be provided with hollow support bar in described housing;
Pull bar is provided with in described support bar;
One end that pull bar is positioned at outside support bar is provided with draw ring;
The other end of pull bar is provided with two Hook for removal of intrauterine device;
One end of two Hook for removal of intrauterine device is articulated with the end of pull bar;
Compress Spring is provided with in the middle of two Hook for removal of intrauterine device;
Described support bar inwall is provided with the first bracing frame;
Described pull bar is through the first bracing frame;
The end winding support of described support bar near the one end of getting annular distance is provided with photographic head;
Described photographic head is provided with wire, and wire is positioned at the inside of support bar;
Described photographic head is connected with display screen by wire;
Described display location is in the outside of housing.
Improve as one:
The end of described housing is provided with the second bracing frame, and described support bar is through the second bracing frame.
The setting of the second bracing frame, is convenient to support bar aligning and gets annular distance, and then be convenient to alignment ring, improve success rate.
As further improvement:
Described second bracing frame is cross structure, is provided with LED near the side of getting annular distance.
The setting of LED, can improve enough light to doctor, make it find ring accurately, and then once gets ring success.
Owing to have employed technique scheme, the present invention is preserved from, by arranging the first bracing frame and the second bracing frame, to find the ring that will get accurately by tubular shell protection vaginal walls; And the setting of photographic head and display screen, make doctor only need watch the position that display screen just can know Hook for removal of intrauterine device when getting ring, operation support bar and pull bar make Hook for removal of intrauterine device alignment ring, then pull draw ring, ring is taken off from cervix uteri, simple to operation, one-time success rate is high, substantially increases work efficiency.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.

Detailed description of the invention
Embodiment: as depicted in figs. 1 and 2, ring instrument is got by a kind of gynecological, comprises tubular shell 1, and described housing 1 one end is provided with ring flange, and the other end is hemispherical configuration, and centre is provided with gets annular distance 13, is provided with hollow support bar 3 in described housing 1;
Pull bar 4 is provided with in described support bar 3;
Pull bar 4 one end be positioned at outside support bar 2 is provided with draw ring 5;
The other end of pull bar 4 is provided with two Hook for removal of intrauterine device 12;
One end of two Hook for removal of intrauterine device 12 is articulated with the end of pull bar 4;
Compress Spring 11 is provided with in the middle of two Hook for removal of intrauterine device 12;
Described support bar 3 inwall is provided with the first bracing frame 9;
Described pull bar 4 is through the first bracing frame 9;
The end winding support of described support bar 3 near the one end of getting annular distance 13 is provided with photographic head 10;
Described photographic head 10 is provided with wire 7, and wire 7 is positioned at the inside of support bar 3;
Described photographic head 10 is connected with display 6 by wire 7;
Described display 6 is positioned at the outside of housing 1.
The end of described housing 1 is provided with the second bracing frame 2, and described support bar 3 is through the second bracing frame 2.
Described second bracing frame 2 is cross structure, LED 8 is provided with near the side of getting annular distance 13, the quantity of LED 8 can be one and also can be two, three or four, arrange as required, its power supply can for being arranged on the battery on the second bracing frame 2, also can be drawn outside housing 1 by wire, be connected with power supply.
During use, housing 1 is slowly extend into intravaginal, opens LED 8, promote support bar 3, aim at the ring that will take away, then stretched into by pull bar 4 alignment ring, two Hook for removal of intrauterine device 12 open under the tension force of Compress Spring 11, until two Hook for removal of intrauterine device 12 after correct position, pull draw ring 5, under the effect on two Hook for removal of intrauterine device 12 edges in support bar 3 end, ring is blocked, continue to pull draw ring 5, just ring can be taken away from cervix uteri.Whole process operation is simple, and one-time success rate is high, and effectively protects vaginal walls, substantially increases work efficiency.
