Teaching model based on antenatal diagnosis puncture technology and application method thereof

Abstract

The present invention belongs to the field of medical teaching tools, and relates to a teaching model based on an antenatal diagnosis puncture technology and an application method thereof. The teaching model based on the antenatal diagnosis puncture technology comprises a model main body, an assembling mechanism and an observation mechanism; and the model main body comprises a uterus model body, asupport, a lower abdomen model body, an upper abdomen model body, an umbilical cord model body and a placenta model body. When practicers perform simulation training, model images in the observationmechanism are employed to perform puncture operation, when puncture needles contact a mini acupuncture sensor arranged at the target puncture position of the model, the mini acupuncture sensor immediately emits alarm prompting signals to inform the practicers of completion of the puncture operation, the practicers establish space correspondence of two-dimensional images in a visual mirror and a three-dimensional entity of a puncture model through repeat training so as to improve the puncture operation accuracy and stability.

Description

technical field [0001] The invention belongs to the field of medical teaching appliances, and relates to a teaching model based on prenatal diagnosis puncture technology and a using method thereof. Background technique [0002] Prenatal diagnostic puncture technology is a diagnostic technique that takes placental or fetal cells for cytogenetic and molecular biological analysis of prenatal fetuses. According to different puncture and sampling sites, it can be divided into chorionic villi biopsy, amniocentesis and umbilical vein puncture. Chorionic villus biopsy is generally performed in the first trimester, while amniocentesis and umbilical vein puncture are performed in the second and third trimesters. [0003] In the current clinical practice, the above-mentioned operation techniques require doctors to perform invasive operations under the guidance of ultrasound. Improper operation may cause fetal injury, placental hematoma and the risk of miscarriage. In addition, the ac...

Problems solved by technology

Due to the professionalism of the above operations and the high risk of trauma, it is difficult for even specialist doctors to have the opportunity to perform actual patient operations

In recent years, simulation teaching has developed rapidly, but due to the complexity of prenatal diagnostic puncture technology, there is still no corresponding teaching model. Specialists can only rely on clinical observation to learn, and then carry out practical exercises on real patients. a great medical safety hazard
