Description
Technical field
This utility model relates to medical gynecologic operating instruments, is a kind of combination type pregnant capsule detection puncture needle.
Background technology
In medicinal, scar pregnancy Wang, cornual pregnancy are all rare types in ectopic pregnancy, cause inhale palace not exclusively and then continue gestation and cause uterine rupture because cornual pregnancy position is special; And Cesarean esction cicatrix gestation increases due to the weak and fibrous tissue of cicatrix place flesh wall, there is the defect of inner membrance interstitial decidua; When germ cell implantation can cause the serious consequence such as massive hemorrhage and uterine rupture at Cesarean esction cicatrix place.Because current cesarean delivery rate increases, cicatrix position gestation showed increased, mainly adopts Drug therapy, operative treatment two kinds of methods at present.Medicine is expectant treatment, can systemic administration and local application, and systemic administration treatment course for the treatment of is long, therapeutic effect is poor; Another kind of operation method adopts double-cavity ovum taking needle puncture local injection, at pregnant intracapsular injection medicine, embryo lost activity; But find in Clinical practice, because double-cavity ovum taking needle is disposable apparatus, treatment cost is very high, carry out under needing special transvaginal sonography ripple to guide, cause medicine can not accurately enter in pregnant capsule again because puncture position is inaccurate, also there is puncture needle and easily stab uterine mucosa and muscle layer causes bleeding to occur, directly affect therapeutic effect.The disclosed patent No. is 2011204129511, name is called the technology of safety puncture injection needle, although stab uterine mucosa in order to avoid puncture needle and muscle layer causes bleeding to occur, sleeve pipe is connected in puncture needle outer tube sleeve, its sleeve pipe adds the safety of puncture, but because sleeve pipe visualization ratio under ultrasound wave is low, operator is with regard to its accuracy that punctures, paracentesis depth is not easy to grasp, cause puncture injection mortality high, cause patient to continue serious consequence that gestation causes massive hemorrhage and uterine rupture, turn increase the misery of patient, so far can not in clinical middle extensive use.
Utility model content
The purpose of this utility model is to provide a kind of combination type pregnant capsule detection puncture needle, because probe has supersonic wave development, so can judge the distance of probe head and pregnant capsule under ultrasonic leading clearly; There is development effect good, add pregnant capsule puncture injection accuracy, safety, drug dose control accurate, easy to operate, feature that patient treatment cost is low.
The purpose of this utility model is achieved through the following technical solutions: combination type pregnant capsule detection puncture needle, it comprises injector syringe, puncture needle and probe, injector syringe is connected with puncture needle, the handle end of probe is provided with opening, probe inner chamber is cavity, puncture needle inserts in probe cavity from opening part, puncture needle rear end and injector syringe junction are provided with scale marker, the needle point of puncture needle is positioned at inside the port of export of probe, and the length of puncture needle is identical with the length of probe.The scale marker that puncture needle rear end is provided with is blue color circle cast; Probe front end is provided with scale marker.The unit centimetre of probe front end high scale mark, the unit of the scale marker on puncture needle is millimeter.
Model case: 1, the Meng XX, 40 years old, menolipsis 2 months, from taking abortifacient before being in hospital, having no embryo and getting rid of, being hospitalized for treatment in August, 2013, be shown as scar pregnancy Wang through B ultrasonic, intrauterine enclosed mass size is 6.5 × 5.1 × 5 centimetres, blood chorionic-gonadotropin hormone 117790mIu/ml when being admitted to hospital; Clinical practice methotrexate 20 milligrams of intramuscular injection after being admitted to hospital, adopt this utility model combination type pregnant capsule detection puncture needle under monitoring ultrasonic to enclosed mass local puncture injection methotrexate 50 milligrams simultaneously, treat and detect blood chorionic-gonadotropin hormone 147.14mIu/ml afterwards in 56 days, decline 99.87%, prove that embryo loses activity.
2, health XX, 30 years old, the pregnancy period checked, be shown as cornual pregnancy through ultrasound diagnosis, gestation sac size is 2.2 × 1.4 × 0.9 centimetre, blood chorionic-gonadotropin hormone 25635mIu/ml when being admitted to hospital, and visible plumule and primitive heart tube are beaten; Clinical practice this utility model combination type pregnant capsule detection puncture needle after being admitted to hospital, detection puncture needle is bent to required angle, to gestation sac local injection methotrexate 50 milligrams under monitoring ultrasonic, local injection is after 26 days, detect blood chorionic-gonadotropin hormone 7179mIu/ml, decline 71.99%, prove that embryo loses activity.
3, Zhao X, 36 years old, the pregnancy period checked, be shown as scar pregnancy Wang through ultrasound diagnosis, gestation sac size is 3.9 × 3.3 × 2.9 centimetres, and blood chorionic-gonadotropin hormone 86529mIu/ml is shown in that plumule and primitive heart tube are beaten; After being admitted to hospital, the pregnant capsule of clinical practice this utility model combination type detects puncture needle under monitoring ultrasonic to gestation sac local injection methotrexate 50 milligrams, injection methotrexate after 14 days, detect chorionic-gonadotropin hormone 36590mIu/ml, decline 57.71%, prove that embryo loses activity.
4, open XX, 39 years old, pregnancy period checks, scar pregnancy Wang is shown as through ultrasound diagnosis, gestation sac size is 2.4 × 1.6 × 1.6 centimetres, see that plumule and primitive heart tube are beaten, blood chorionic-gonadotropin hormone 21681mIu/ml is detected when being admitted to hospital, after being admitted to hospital, the pregnant capsule of clinical practice this utility model combination type detects puncture needle under monitoring ultrasonic to gestation sac local injection methotrexate 50 milligrams, 5 days colporrhagia multirow uterine curettages after injection methotrexate, see floss hair, be in hospital and within 17 days, detect blood chorionic-gonadotropin hormone 97.67mIu/ml, decline 99.54%, proof embryo lose activity.
5, Song XX, 38 years old, pregnancy period checks, scar pregnancy Wang is shown as through ultrasound diagnosis, gestation sac size is 1.3 × 1.3 × 0.8 centimetre, see that plumule and primitive heart tube are beaten, blood chorionic-gonadotropin hormone 8616mIu/ml when being admitted to hospital, puncture needle is detected under ultrasonic monitoring to pregnant capsule local injection methotrexate 50 milligrams at the pregnant capsule of clinical employing this utility model combination type after being admitted to hospital, injection methotrexate detects blood chorionic-gonadotropin hormone 2880mIu/ml in 18 days afterwards, decline 66.57%, prove that embryo loses activity.
This utility model is proved by clinic trial: because probe has the good feature of development effect under ultrasonic leading, so namely can judge distance, the position relationship of probe head and pregnant capsule clear, accurately under conventional ultrasound guides; Utilize the pliability that probe possesses simultaneously, have under good bendability condition, the puncture angle of puncture needle can be operated arbitrarily, puncture accuracy is strong.Under ultrasonic leading, determine that the distance accuracy of probe head and pregnant capsule is very high, the round and smooth puncture needle that can prevent again of probe end stabs uterine mucosa and muscle layer simultaneously; And the scale marker determination paracentesis depth by puncture needle is established, precision reaches more than 98%, avoids due to puncture failure, causes patient to continue gestation and causes the serious consequence such as massive hemorrhage and uterine rupture; This utility model is accurate to drug dose after pregnant capsule puncture, minimizing drug waste; And probe of the present utility model is easy to sterilization, can reuses, and namely alleviates patient treatment cost, improve again and treated effect, structure is simple, practical.
