Obstetrical clinical antenatal diagnosis and examination device

Abstract

The clinical antenatal diagnosis and examination device comprises a shell, a puncture needle and a sample collection needle cylinder, an ultrasonic probe is installed in the shell, a driving motor is installed at the lower end of the shell, a sliding groove is formed in the position, above the driving motor, of the shell, and a threaded shaft connected with the driving motor is rotationally connected into the sliding groove; a magnet sliding block is slidably connected into the sliding groove, and a threaded hole which is in threaded connection with the threaded shaft downwards penetrates through the magnet sliding block. A sliding rail is arranged on the outer side, close to the sliding groove, of the shell and slidably connected with a sliding iron sheet matched with the magnet sliding block, the sliding iron sheet is outwards and horizontally provided with a U-shaped clamp used for clamping a puncture needle, a puncture guide block is arranged at the position, at the lower end of the sliding rail, of the shell, and a guide hole for the puncture needle to penetrate through is formed in the position, at the lower end of the sliding rail, of the shell and penetrates through the puncture guide block downwards. And one end of the sample collection needle cylinder is detachably connected with the puncture needle. Ultrasonic imaging can be combined for automatic puncture, the puncture depth is automatically judged according to ultrasonic waves, and the puncture depth is more accurate.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an obstetric clinical prenatal diagnosis and examination device. Background technique [0002] Prenatal diagnosis refers to the detection and diagnosis of the developmental status of the embryo or fetus and whether it is suffering from diseases before birth. In order to grasp the opportunity, for curable diseases, choose the appropriate time for intrauterine treatment. Prenatal diagnosis in a narrow sense, only for diseases with abnormal fetal chromosome number or structure, fetal-derived cells are obtained by invasive diagnostic methods (chorionic villus sampling, amniocentesis and percutaneous umbilical puncture) during pregnancy, and chromosome nucleus is performed. Type detection, detection and diagnosis, can terminate pregnancy as soon as possible before delivery. [0003] Among them, amniocentesis is to puncture the amniotic cavity with a puncture needle, and then...

Problems solved by technology

However, the puncture is a doctor who combines the ultrasound image and his own experience to puncture the puncture needle from the abdomen of the pregnant woman. The puncture depth is judged by the doctor's experience, and there is a risk of insufficient puncture depth or puncture the fetus.
