PLHX1003Endobronchial Ultrasound (EBUS) Training Model Main components Main airway, bronchi (second to fifth-level branches) It is applicable to device operation demonstration, clinical skill teaching, and doctor-patient communication Ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). The ultrasound bronchoscope or the micro ultrasound probe can be used to enter the endotracheal lumen for ultrasound scanning to obtain ultrasound imaging of the tracheal lymph. And the puncture needle can penetrate the trachea to obtain the simulated lymphoid tissue specimen. The trachea has seven enlarged lymph nodes: 2R, 4R, 10R, 2U4U 10L, 7. Mobile head, nasal cavity, larynx (epiglottis and glottis), main airway, bronchi (second to fifth-level branches) It is applicable to pediatric bronchial device operation, training and demonstration; clinical skill teaching, doctor-patient communication Pediatric bronchoscope operation training Pediatric bronchoscopic device operation training and device demonstration
