Background
Amniotic fluid puncture examination is a method of prenatal diagnosis, and is generally suitable for prenatal diagnosis of middle-term pregnancy. The amniotic fluid puncture is performed by leading an elongated puncture needle to pass through the belly and the uterine wall of a pregnant woman under the guidance of ultrasonic equipment, and finally entering into a amniotic fluid cavity, and extracting a certain amount of amniotic fluid for testing. During the process of extracting amniotic fluid by using the injector, the puncture needle can shake and even be pulled out along with the extraction action, so that the risk of harm to pregnant women and fetuses exists, and the corresponding operation of medical staff is not facilitated; multiple groups of amniotic fluid can be extracted for chromosome detection, gene chip detection, immune detection and other examination respectively by one-time amniotic fluid puncture, and each group of amniotic fluid is extracted by using different syringes respectively, so that the puncture needles can be rocked when the syringes are replaced. The clinical practice generally needs to manually grab and stabilize the puncture needle and then replace the injector, but the operation is inconvenient, and meanwhile, a certain sensing and controlling risk is brought to the hand touching the puncture needle. There are some devices available in the prior art that can be used to secure amniotic fluid puncture needles, but such devices require fixation to the pregnant woman's undergarment prior to puncturing, limiting the position of the puncture needle during puncturing, and interfering with the puncturing operation.
The Chinese patent application No. CN201720191728.6 discloses a amniotic fluid puncture needle fixing device which comprises a chassis and a chassis fixing piece, wherein a round hole for penetrating a puncture needle head is formed in the chassis, the chassis and corresponding parts are fixed on the abdomen of a pregnant woman when the device is used, and then the puncture needle penetrates into the amniotic fluid cavity of the pregnant woman through the round hole. The operation is that the puncture needle must be pierced from the current round hole position once the chassis is fixed on the skin of the pregnant woman, and if the ultrasonic equipment finds that the fetus moves to the position or approaches the position, the needle can not be inserted from the position any more in order to avoid hurting the fetus, the needle insertion position needs to be selected again, and the whole device is removed and fixed at the newly selected needle insertion position again, so that the flexibility is reduced, and unnecessary work is increased; after the device is fixed, the puncture operation is performed, and the operation process of amniotic fluid puncture is influenced due to the existence of the device, so that the medical staff is prevented from performing needle insertion.

As a further technical improvement, the inner side of the clamping head on the fixing clamp is detachably provided with a clamping piece. The clamping piece can be a plastic piece, and can be detachably and replaceably fixed by sticking or penetrating pins or screws and the like into the fixing clamp and the clamping piece.
The using method of the amniotic fluid puncture needle fixture device comprises the following steps:
when in use, firstly, the amniotic fluid puncture position which avoids the fetus is selected through an ultrasonic instrument, and the amniotic fluid puncture needle is inserted into the amniotic cavity of the pregnant woman; placing the patch and the base on the abdomen of the pregnant woman, wherein the puncture needle is positioned at the puncture needle opening after passing through the avoidance opening; the device is stuck and fixed on the abdomen of the pregnant woman through a patch; the position and the height of the fixing clamp are adjusted through the arc sliding track and the telescopic rod, so that the position of the fixing clamp does not obstruct subsequent operation; the puncture needle is fixed through the fixing clamp, so that the puncture needle cannot shake and move, and finally, the subsequent operation can be continued; if the fixing clip prevents the operation in the subsequent operation of puncture, the fixing clip can be loosened, and the puncture needle can be clamped after the position of the fixing clip is adjusted through the arc-shaped sliding track and the telescopic rod.
The technical scheme of the utility model has the following beneficial effects:
1. the device can fix the puncture needle of amniotic fluid puncture through the fixing clamp, and prevent bending and shaking.
2. The device can be placed at the corresponding position after the puncture is completed through the avoiding port and the needle threading port instead of being placed at the beginning, so that the puncture position is not limited, and the puncture operation is not influenced.
