Product Components	Main airway, bronchi ( secondary to fifth level branches )
Product Materials	High soft silicone, hardness: 18A-30A
Size	Model Length: 28 centimeters (11 inches) Model Width: 28 centimeters (11 inches) Model Height: 14 centimeters (5.5 inches)
Product Function	Ultrasound guided transbronchial needle aspiration biopsy ( EBUS-TBNA )
Product Features	Based on adult lung CT data, a bronchial model was created using soft silicone and ultrasound materials. Ultrasound bronchoscopy or micro ultrasound probe can be used to enter the tracheal lumen for ultrasound scanning to obtain ultrasound imaging of tracheal lymph nodes. The puncture needle can penetrate the trachea to obtain a simulated lymphoid tissue specimen. There are seven enlarged lymph nodes in the trachea: 2R, 4R, 10R, 2L, 4L, 10L, 7.
