Abstract
The invention relates to a single-cavity oocyte collector. The collector comprises a puncture needle, a silica gel plug, a negative pressure connector, a negative conveying flexible tube, an extraction connecting tube, a sleeve tube and a handle. One end of the extraction connecting tube penetrates through the silica gel plug. The tail of a needle handle of the puncture needle is inserted into the other end of the extraction connecting tube. The position where the extraction connecting tube is connected with the puncture needle is wrapped by the connecting flexible tube. The sleeve tube penetrates through the extraction connecting tube. The puncture needle comprises a syringe needle and the needle handle. The inner diameter of the puncture needle ranges from 0.5 mm to 0.8 mm, the length of the puncture needle ranges from 15 cm to 20 cm, the length a of the syringe needle is 5 mm, and the angle alpha of the syringe needle ranges from 8 degrees to 12 degrees. The tail of the rear end of the syringe needle is designed in an arc shape. The inner wall and the outer wall of the tail of the rear end of the syringe needle are in circular arc transition. The tail of the front end of the syringe needle and the head of the rear end of the syringe needle are in circular arc transition. Due to the facts that the length of the syringe needle of the puncture needle is large and the angle is small, the puncture needle is sharper, an opening of the puncture needle is larger, the larger contact area is generated after rotation, and the single-cavity oocyte collector saves cost and can be produced in bulk.
Description
Technical field
The invention belongs to medical instruments field, relate to a kind of single chamber oocyte harvester.
Background technology
The sickness rate of infertility is more and more higher, and along with 1978 by adopting In vitro fertilization technology to be born in the world after first case baby, auxiliary procreation technology becomes the primary treatment means of infertility.Accept the process that the women of Assisted Reproductive Techniques Treatment inevitably will accept to get ovum, under ultrasonic guidance, with pin transvaginal puncture, enter ovary and draw ovum.Very pain of this process patient, often needs calm or anesthesia, and has vein, vagina, ovary bleeding due to trauma, and postoperative bellyache and pelvic cavity secondary infection.Now the normal ovum puncture needle bore of getting using has 16G, 17G, 18G, tetra-specifications of 20G, and needle point rhombus, is provided with and rinses chamber.
Have experiment report, use the thinner pin of bore to get ovum amount of bleeding fewer, patient's pain is lighter, and obtains ovum number without significant difference.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of single chamber oocyte harvester is provided.

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, for measuring puncture needle, insert the degree of depth of ovary.
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.
The present invention all needs sterilizing before dispatching from the factory, and is disposable use.
Beneficial effect of the present invention:
The present invention compares traditional puncture needle; the needle point of puncture needle of the present invention 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, reduced 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 the present invention substitutes exposed puncture needle part in vitro with other cheap hard materials, greatly cost-saving, can produce in a large number.
The present invention can collect 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.
