Amniocentesis positioning device used for obstetrics and gynecology department

Abstract

The invention discloses an amniocentesis positioning device used for the obstetrics and gynecology department. The positioning device comprises a positioning device body and first fixing blocks, the two first fixing blocks are fixedly connected to the front face of the positioning device body, the opposite faces of the two first fixing blocks are fixedly connected with the two ends of a sliding rod respectively, the surface of the sliding rod is sleeved with a sliding bush, the front face of the sliding bush is movably connected with the back face of a needle tube through a pin shaft, and a positioning needle is arranged on the lower surface of the needle tube. A first hook and loop fastener, a second hook and loop fastener, fixing bands, sponge cushions, sliding blocks, sliding grooves, bearings, the needle tube, the positioning needle, waist-protecting cushions, telescopic rods, springs, connecting plates, clamping rods, clamping grooves, positioning bands, a fixing buckle, the sliding rod and the sliding bush are used in cooperation, the positioning needle can accurately puncture a pregnant women, in this way, the difficulty of puncturing is lowered, the accuracy of puncturing is improved, and the working difficulty of a doctor is lowered.

Description

technical field [0001] The invention relates to the technical field of amniocentesis, in particular to an amniocentesis positioning device for obstetrics and gynecology. Background technique [0002] Amniocentesis is a method of prenatal diagnosis. The puncture site is selected. The pregnant woman is placed in the supine position. After a comprehensive routine ultrasound examination of the fetus, observe the location of the placenta and understand the location of the fetal head, trunk, limbs, and umbilical cord. The distribution of the amniotic fluid, and then focus on the observation of the amniotic fluid, and then select the puncture point. The principle of puncture point selection: choose the front abdomen, not the side abdomen, choose the part with more amniotic fluid and close to the body surface, choose no placenta, fetal limbs and umbilical cord, and pregnant women Structural parts such as blood vessels. After the puncture point is determined, it is necessary to meas...
