Description

Visual amniotic fluid puncture outfit Technical Field The utility model relates to the technical field of medical appliances, in particular to a visual amniotic fluid puncture outfit. Background Amniotic fluid puncture is a common prenatal diagnostic procedure for detecting the presence of chromosomal abnormalities or other genetic disorders in a fetus. This procedure involves the doctor taking a small sample of amniotic fluid from the amniotic cavity in the uterus of a pregnant woman under the guidance of b-mode for laboratory analysis and prenatal diagnosis of the fetus. Although this technology is well established, there are still certain risks and challenges. At present, most amniotic fluid puncture equipment is directly connected with the top end interface of a puncture needle by using a syringe, and after successful puncture, an operator needs to fix the puncture needle according to the guidance of b ultrasonic, and continuously negative pressure is used for extracting amniotic fluid samples. While modern amniotic fluid puncture is typically conducted under ultrasound guidance, not all puncture devices are designed to be convenient enough for use with ultrasound devices. In addition, since two amniotic fluids are required, when the syringe is replaced by extracting the amniotic fluids, the needle point can shake, and the fetal and maternal tissues can be damaged, so that there is room for improvement. Disclosure of utility model The utility model aims to solve the defects in the prior art and provides a visual amniotic fluid puncture outfit. The method has the advantages that a doctor can intuitively perform puncture operation, the risk of accidentally injuring fetal and maternal tissues is obviously reduced, the position and the puncture depth of the needle head can be accurately judged, and the amniotic fluid puncture efficiency is improved. In order to achieve the above purpose, the present utility model adopts the following technical scheme: the utility model provides a visual amniotic fluid puncture ware, includes superfine endoscope and puncture part, the puncture part includes T type drainage tube, the both sides of T type drainage tube all are provided with the drainage connector, the drainage connector is controlled through the flow valve, the bottom of T type drainage tube is provided with the puncture needle tubing, the top of T type drainage tube is connected with superfine endoscope through connecting the binding clasp, the bottom of superfine endoscope is provided with superfine endoscope camera lens, superfine endoscope lens inserts in the puncture needle tubing. Through the technical scheme, when the amniotic fluid puncture needle is used, a doctor firstly selects the optimal puncture point under the guidance of B ultrasonic, then the puncture needle tube is vertically punctured into the selected position, the doctor can accurately judge the puncture position and depth by means of the high-definition real-time image provided by the ultra-fine endoscope lens, ensure that the amniotic fluid can safely reach the amniotic fluid cavity, once the doctor confirms that the position is correct, the doctor can start the flow valve to acquire a proper amount of amniotic fluid according to the requirement, the doctor can intuitively perform the puncture operation, the risk of accidentally injuring fetal and maternal tissues is obviously reduced, the position and the puncture depth of the needle head can be accurately judged, and the amniotic fluid puncture efficiency is improved. The utility model is further arranged that the bottom of the puncture needle tube is in an inclined plane structure. Through the technical scheme, the bottom is designed to be of an inclined plane structure, so that damage to tissues is reduced, and good penetrating power is maintained. The connecting fastener further comprises a rotating sleeve, wherein the inner wall of the rotating sleeve is provided with internal threads, the top of the T-shaped drainage tube and the bottom of the superfine endoscope are respectively provided with external threads, and the internal threads are matched with the external threads. Through the technical scheme, the rotary sleeve can be rotationally locked, so that the superfine endoscope and the puncture part are firmly connected, and loosening or falling off is prevented. The utility model is further arranged that a sealing ring is arranged at the joint between the superfine endoscope and the puncture part.
