Description
Technical field
The invention belongs to medical instruments field, relate to a kind of single chamber oocyte collector.
Background technology
The sickness rate of infertility is more and more higher, and be born in the world after first case baby by adopting In vitro fertilization technology along with 1978, auxiliary procreation technology becomes the essential therapeutic arsenals of infertility.The women accepting Assisted Reproductive Techniques Treatment inevitably will accept the process of getting ovum, namely enters ovary with pin transvaginal puncture under ultrasound guidance and draws ovum.This process patient very pain, normal needs calm or anesthesia, and have vein, vagina, destroying in overy are hemorrhage, and postoperative bellyache and pelvic cavity secondary infection.Now the normal ovum puncture needle bore of getting used has 16G, 17G, 18G, 20G tetra-specifications, and needle point rhombus, be provided with and rinse chamber.
Have Experimental report, use the thinner pin of bore to get ovum amount of bleeding fewer, patient 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, provide a kind of single chamber oocyte collector.
The present invention includes puncture needle, silica gel plug, negative pressure union joint, negative pressure transportation flexible pipe, extract connection tube, sleeve pipe, hands handle;
One end of negative pressure transportation flexible pipe is connected with negative pressure union joint, other end through-silicon plug; Negative pressure union joint is for pinning negative pressure device; Extract one end through-silicon plug of connection tube, the needle handle afterbody of puncture needle inserts the other end extracting connection tube; The junction extracting connection tube and puncture needle is coated with connecting hose, and for preventing puncture needle from departing from extraction connection tube, and connecting hose fixture is fixed; Sleeve pipe runs through extraction connection tube, and one end fixture screw thread of sleeve pipe is fixed, and the other end inserts handle and is fixedly connected with; The diameter of this sleeve pipe is less than the oriented diameter of the present invention's puncture supporter in use used;
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; With scale on sleeve pipe, insert the degree of depth of ovary for measuring puncture needle.
The shape of silica gel plug is truncated cone-shaped, for clogging oocytes collection device bottleneck, is applicable to the oocytes collection device of different bore;
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, do not produce sharp-pointed corner angle, not easily scratch vagina; Needle tip afterbody and syringe needle rear end head arc transition, do not produce sharp-pointed corner angle, not easily scratch vagina.
Needle tip adopts the inner arc design of syringe needle rear end extended line, makes needle point thinner, reduces the hemorrhage of patient and damage, reduce stomachache postoperative in art.
Needle handle lateral surface is provided with loop-shaped ultrasound recognition marks, and close needle end and the syringe needle rear end tails distance b of loop-shaped ultrasound recognition marks are 1 ~ 2mm.
The present invention all needs sterilizing before dispatching from the factory, and is single 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 stomachache postoperative in art; thus tranquilizer or narcotic using dosage can be reduced or do not use tranquilizer or anesthetis, patient recovers normal activity sooner.
The needle length of puncture needle is longer, angle is less, thus make puncture needle sharper keen, the opening of puncture needle is larger, larger contact area is produced after rotating, easily that the scraping of follicle content is cleaner, without the need to rinsing, reduce operation time, decrease the probability of postoperative infection, can reach maximum equally and obtain ovum rate.
The cambered design of needle handle, reduces the cutting to tissue and tearing, reduces the damage to ovum-ovarian cumulus complex, add the safety of ovum.
Loop-shaped ultrasound recognition marks on needle handle forms by arranging point-like groove more, can 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 other hard materials that the present invention is cheap substitute exposed puncturing needle part in vitro, greatly cost-saving, can produce in a large number.
The present invention can collect rapidly maximum oocytes, and at utmost minimizing cell injury and semitransparent layer break, and operating process is visual, hose size and use raw material rationally, strengthen serviceability, single use, prevent cross infection, safe advantage simple to operate.
