Description
Technical field
This utility model relates to the medical apparatus and instruments in a kind of supplementary reproduction medical procedure, and particularly, this utility model relates to a kind of novel asepsis single cavity ovum-picking needle device.Described asepsis single cavity ovum-picking needle device needle tubing diameter is thinner, and is littler to the ovary wound, adopts electromechanical interlocks, can keep dashing, inhaling simple to operate, reliable, the seriality of ovum process, possesses the function of single cavity ovum-picking needle device and double-cavity ovum taking needle simultaneously.
Background technology
Current society, because the continuous enhancing of the quickening of work rhythm and work competitive pressure, and under the combined influence of other various factorss, the number of infertile patient increases day by day.Implement to become pregnant with artificial supplementary mode clinically, become effective medical procedure.
The first routine test-tube baby---since Louis's cloth youth was born, huge variation took place in auxiliary procreation technology and application thereof in the world since 1978.The successful test-tube baby of first example is to get ovum with peritoneoscope in free period.Still have a minority to advocate in IvF, to use free period now, but almost generally adopt transvaginal to get ovum.Even laparoscopic use in gamete intra-Fallopian transfer (GIFT), is got ovum with peritoneoscope and abandoned mostly, it is first-selected method that transvaginal is got ovum.The aseptic invention of getting the ovum pin of disposable use, as a kind of important medical apparatus and instruments in the supplementary reproduction medical procedure, the hope that makes infertile patient finish fertility becomes possibility.
Transvaginal was got ovum since 1978 under the ultrasonic guidance, since getting ovum by peritoneoscope, get the ovum technology and had very much progress, guide down through skin bladder and per urethra bladder from abdominal ultrasonic, get ovum to modern Transvaginal Ultrasound, this easy and safe relatively method has improved the efficient of getting ovum, can carry out under local anaesthesia, and can combine with various auxiliary procreation technology (ART).
Updating of ultrasonic technique makes these progressive possibilities that becomes.Having had small-sized transvaginal sonography probe now, is 5MHz or 7.5MHz transvaginal probe such as frequency, and its resolution height uses patient's relative comfort.The resolution height helps accurately to distinguish and locate follicle, by rotating detector simply, in two dimensional image, determine the shape of follicle, low echo follicle is distinguished from same hypoechoic pelvic blood vessels, and each follicle can be sucked exactly like this, has improved the ovum rate of getting greatly.
Transvaginal probe also can provide a kind of device of fixedly ovary, by means of the support force from the pelvis wall, makes puncture needle lightly arrive ovary fast along the back, uterus.Ovary further fixing want armrest art assistant with hands from pubis or abdominal part finish.There are several needle guides should select according to different ultrasonic probes for choosing.
Getting the most normal 16G of selecting for use of ovum or 17G pin, can be single chamber pin or bilumen needle.Estimate to use double channel catheter when follicle need wash, such as external fertilization IvF in free period.Double channel catheter can be with sucking-off liquid and flushing liquor shunting, and making liquid is one-way flow at intracavity all the time, helps getting ovum.Puncture needle has a hyperechoic needle point, helps location, puncture and the sucking-off follicle of pin.Select sharp keen puncture needle to thrust follicle rapidly, alleviate patient's sense of discomfort, reduce moving of ovary.Therefore the first-selected disposable aspiration needle that uses.Through repeatedly getting ovum, repeat vaginal wall and enter, local organization meeting hypertonicity, contact tub wall or fallopian tube, syringe needle can rust or bending.Therefore, may in operation, change pin, especially when the follicle suction encounters difficulties.After entering the preceding and rapid taking-up of vagina each time, all to wash with treatment fluid.
The patent No. discloses a kind of single-lumen ovum pickup device for the utility model patent of " 200420097990.7 ", its structure comprises that the end is provided with the puncture needle in ultrasonic echo district, handle, collecting pipe, sealing-plug, negative pressure Connection Block and negative pressure connection tube, collecting pipe one end joins by handle and puncture needle, the other end passes sealing-plug, one through hole is set on sealing-plug, one end of negative pressure connection tube and the through hole on the sealing-plug join, and the other end and negative pressure Connection Block join.
The patent No. discloses a kind of ovum device of getting for the utility model of " 200820026603.9 ", belong to medical apparatus and instruments, its structure comprises that the end is provided with the puncture needle in ultrasonic echo district, handle, collecting pipe, test tube plug, vacuum extractor and negative pressure connection tube, collecting pipe one end joins by handle and puncture needle, the other end passes the test tube plug, at test tube one through hole is set beyond the Great Wall, an end of negative pressure connection tube and test tube through hole beyond the Great Wall join, and the other end and vacuum extractor join.
The shortcoming of above-mentioned patented technology is: its needle tubing diameter is done slightlyer, and is big to the ovary wound, thereby increased patient's misery.Make that patient's recovery period is long.Easy in the integrated operation, medical procedure is controlled
In addition, above-mentioned collecting pipe one end joins by handle and puncture needle, and the other end passes sealing-plug, and a through hole is set on sealing-plug, and an end of negative pressure connection tube and the through hole on the sealing-plug join, and the other end and negative pressure Connection Block join.Handling characteristics, be that transvaginal punctures to ovary under peritoneoscope or ultrasonography monitoring means, collect a plurality of ovums rapidly., but generally follicle often is trapped in and sticks on the ovarian wall, makes the success rate of manually getting ovum reduce.
For avoiding the deficiency of above-mentioned single-lumen ovum pickup chamber pin, also the someone has designed double-cavity ovum taking needle, promptly on operating grip, be with a divided manifold tee joint, after puncturing, ovary is washed with low-pressure washing liquid, make ovum avoid on ovarian wall, being detained and adhering to, to improve the success rate of manually getting ovum, the method of the little pin of big needle guard that adopts common double-cavity ovum taking needle realizes the purpose to ovum flushing in the ovary, make the ovum that is attached on the ovarian wall be in floating state, thereby make artificial absorption ovum become possibility, but because adopt the method for the little pin of big needle guard, it is little to make the diameter of large needle to do, and this just makes that the wound face of patient when carrying out medical rescue is relatively large.In addition, the overall diameter of existing bilumen needle can only accomplish that (1.6 ~ 1.69mm), in medical procedure, the doctor can't further select to use 16G according to patient's situation.
This utility model, replaces existing double-cavity ovum taking needle with single cavity ovum-picking needle device, and reach the said function of bilumen needle on function by improving at the deficiency of double-cavity ovum taking needle, reduces patient's medical wound face simultaneously, makes the faster rehabilitation of patient.
