The internal diameter of described extraction connection tube is 1.5～2.0mm;
The material of described sleeve pipe is hard elastic material, and length is 18～25cm; On sleeve pipe, with scale, insert the degree of depth of ovary for measuring puncture needle.
Silica gel plug be shaped as truncated cone-shaped, for clogging oocytes collection device bottleneck, be applicable to the oocytes collection device of different bores;
Described puncture needle comprises syringe needle, needle handle, and the internal diameter of puncture needle is 0.5～0.8mm, and length is 15～20cm, and the length a of syringe needle is 5mm, and angle [alpha] is 8～12 degree.
Syringe needle rear end tails adopts arc line shaped design, makes the aperture area of syringe needle reach maximization, and syringe needle rear end tails inside and outside wall arc transition, does not produce sharp-pointed corner angle, is difficult for scratch vagina; Syringe needle front end afterbody and syringe needle rear end head arc transition, do not produce sharp-pointed corner angle, is difficult for scratch vagina.
Syringe needle front end adopts the inner arc design of syringe needle rear end extended line, makes needle point thinner, reduces the hemorrhage of patient and damage, reduces postoperative stomachache in art.
Needle handle lateral surface is provided with loop-shaped ultrasound recognition marks, and the close needle end of loop-shaped ultrasound recognition marks and syringe needle rear end tails distance b are 1～2mm.
This utility model all needs sterilizing before dispatching from the factory, and is disposable use.
The beneficial effects of the utility model:
This utility model is compared traditional puncture needle; the needle point of this utility model puncture needle is thinner, reduces the hemorrhage of patient and damage, reduces postoperative stomachache in art; thereby can reduce tranquilizer or narcotic using dosage or not use tranquilizer or anesthetis, patient recovers normal activity sooner.
The needle length of puncture needle is longer, angle is less, thereby make puncture needle sharper keen, the opening of puncture needle is larger, after rotation, produce larger contact area, more easily, clean the scraping of follicle content, without flushing, reduce operation time, reduce the probability of postoperative infection, can reach equally maximum and obtain ovum rate.
The arc design of needle handle, reduces cutting and tearing to tissue, reduces the damage to ovum-ovarian cumulus complex, has increased the safety of ovum.
Loop-shaped ultrasound recognition marks on needle handle forms by arranging point-like groove more, can be better by ultrasonic identification, better in ultrasonic lower location, under ultrasonic mediation from transvaginal puncture oocyte collection.
Tradition needle length is longer, and the material cost of puncture needle is higher, and this utility model substitutes exposed puncture needle part in vitro with other cheap hard materials, greatly cost-saving, can produce in a large number.
This utility model can be collected rapidly maximum oocytes, at utmost reduces cell injury and semitransparent layer breaks, and operating process is visual, flexible pipe size and use raw material are reasonable, strengthen serviceability, disposable use, prevent cross infection, safe advantage simple to operate.
