Clinical antenatal diagnosis and examination device for obstetrics and gynecology department

Abstract

The clinical antenatal diagnosis and examination device comprises an operating table, and sliding grooves are formed in the left side and the right side of the operating table in the front-back direction; the number of the first screw rods is two, the rear ends of the two first screw rods are rotatably arranged on the rear side of the inner cavity of the sliding groove through bearings, and the front ends of the first screw rods extend out of the front side of the operating table; the belt pulley sleeves the front side of the outer wall of the first screw rod; the two ends of the belt are connected to the outer walls of the two belt wheels in a sleeving mode correspondingly; the rear end of the rocker is arranged at the front end of the first screw on the right side; the sliding block is inserted into the middle of an inner cavity of the sliding groove in a matched mode, and the sliding block is connected to the middle of the outer wall of the first screw in a threaded mode. The device can prevent the puncture needle from swinging greatly when the needle tube is inserted and pulled out, further can prevent a fetus from being accidentally injured, eliminates potential safety hazards, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a clinical prenatal diagnosis and inspection device for obstetrics and gynecology. Background technique [0002] Prenatal diagnosis refers to the detection and diagnosis of the developmental status of the embryo or fetus, whether it is suffering from diseases, etc. before birth, so as to grasp the opportunities, choose the appropriate time for intrauterine treatment for curable diseases, and select the appropriate time for intrauterine treatment for untreatable diseases. , able to make informed choices; [0003] Amniocentesis is currently the most simple and effective method of clinical prenatal diagnosis of congenital genetic diseases. When performing amniocentesis, the pregnant woman needs to lie flat on the operating table first, and the surgeon uses ultrasound to check whether the fetal heartbeat is normal. Normal, and the puncture site is determined. After the punct...

Problems solved by technology

[0004] However, when amniocentesis is performed, the traditional puncture method usually cannot effectively fix the puncture needle. Because in order to avoid maternal cell contamination, it is usually necessary to draw two milliliters of amniotic fluid first, and pull out the needle tube from the needle to remove the two milliliters of amniotic fluid. Abandon it, replace it with a new needle tube and insert it on the needle head, and if multiple inspections are required, the needle tube needs to be inserted and pulled out multiple times, and when amniocentesis is performed, the puncture needle needs to be inserted into the amniotic cavity, and the fetus grows again In the amniotic cavity, since the traditional puncture method cannot fix the puncture needle, it is very easy to cause the puncture needle to swing greatly in the inner cavity of the amniotic cavity when inserting and pulling out the needle tube, thereby causing the risk of accidentally injuring the fetus, and there is a large Potential safety hazards, inconvenient to use
