Embodiment 1

[0109] Such as figure 1 As shown, the amniocentesis device of the present application includes a U-shaped guide rail 100, a guide rail moving assembly 200, a puncture needle moving assembly 300, an amniotic fluid suction assembly 400, a developing assembly 500, a control unit and an energy supply assembly.

[0110] The main body of the U-shaped guide rail 100 is U-shaped, essentially a guide rail, which is positioned on the guide rail moving assembly 200 and guides the movement of the puncture needle moving assembly 300 .

[0111] The guide rail moving assembly 200 plays a role in moving the U-shaped guide rail 100; the guide rail moving assembly 200 includes a base 210, a guide column 220, a beam 230 and a guide rail driving unit 250; the base 210 Positioned on the ground, it is used to support and position the guide column 220; the guide column 220 is fixedly connected to the base 210, the main body is cylindrical, and the axial direction is perpendicular to the horizontal g...

Embodiment 2

[0121] Considering that the process of amniotic fluid extraction will bring certain pains and may cause the pregnant woman to move, although it is more efficient for pregnant women to extract amniotic fluid standing (no need for the user to lie down), it is not as safe as lying down; therefore, this embodiment is described in Embodiment 1. The structure of the guide rail moving assembly 200 is changed on the basis of the above, so that the user can lie down for extraction, such as figure 2 As shown, the guide rail moving assembly 200 includes a bottom plate 240 and a guide rail driving unit 250 , and the U-shaped guide rail 100 slides on the bottom plate 240 along the height direction of the user under the drive of the guide rail driving unit 250 .

[0122] During the actual operation of the embodiment of the present application, the initial position of the U-shaped guide rail 100 is located at one end of the base plate 240; the user lies on the base plate 240; the device oper...

Embodiment 3

[0126] In order to further improve the working efficiency of the amniocentesis device and avoid the process of transferring amniotic fluid from the syringe to other containers by the device user, this embodiment performs the amniocentesis assembly 400 of the amniocentesis device of Embodiment 1 or Embodiment Change;

[0127] Specifically: if Figure 12 , Figure 13 , Figure 14 , Figure 19 and Figure 20 As shown, the amniotic fluid suction assembly 400 includes a needle assembly 420 and a negative pressure liquid storage tube 460 .

[0128] Such as Figure 14 As shown, the needle assembly 420 includes a needle body 421, a needle body positioning assembly 422, a needle shield 423 and a puncture membrane assembly 424; the needle body 421 is a puncture needle, and the needle body 421 passes through the needle body The positioning assembly 422 is detachably and fixedly connected to the negative pressure liquid storage tube 460, and the needle positioning assembly 422 plays...

Abstract

The invention discloses an amniotic cavity puncture device, which comprises a developing assembly, a control unit and an energy supply assembly, and further comprises a U-shaped guide rail, a guide rail moving assembly, a puncture needle moving assembly and an amniotic fluid suction assembly, wherein the U-shaped guide rail main body is U-shaped, the U-shaped guide rail is actually a guide rail, is positioned on the guide rail moving assembly and is used for guiding the movement of the puncture needle moving assembly, the guide rail moving assembly plays a role in moving the U-shaped guide rail, the puncture needle moving assembly is used for moving a puncture needle, enables the puncture needle to have multiple degrees of freedom and can complete the actions of moving the puncture needleto a puncture position and conducting puncture, the amniotic fluid suction assembly is positioned on the puncture needle moving assembly and plays a role in extracting amniotic fluid, the developing assembly is used for developing, the control unit comprises a control handle and a failure assembly, the failure assembly comprises an acceleration sensor, a logic controller and a cut-off switch, andwhen the moving acceleration of the control handle exceeds a specific value, the logic controller controls the cut-off switch to cut off signal transmission.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an amniocentesis device. Background technique [0002] Amniocentesis, as the name suggests, is a method of prenatal diagnosis, generally suitable for prenatal diagnosis in the second trimester. Amniotic fluid exists in the amniotic cavity; the fertilized egg forms the amniotic cavity on the seventh day of fertilization and produces amniotic fluid. [0003] In the existing major hospitals, when pregnant women are given prenatal diagnosis to check whether the fetus has congenital defects, such as whether there is a cleft lip or congenital diseases, it is usually necessary to use a syringe to connect the puncture needle. Under the development of the probe, the amniotic fluid is inserted into the amniotic cavity of the pregnant woman to manually extract the amniotic fluid, so that it can be sent to the laboratory for chromosome cultivation. [0004] In hospitals, there ...
