The beginner in the study of bronchoscopic technic finds that obtaining suitable material for study of the bronchoscopic field is not the least of his problems.
Teachers of bronchoscopy in general, and Dr. Chevalier Jackson1 in particular, emphasize the dangers attending the use of the special bronchoscopic armamentaria on the human subject without prolonged and painstaking studies on both the cadaver and the living dog. Dr. Jackson advocates daily practice of from one to two hours until several hundred hours have been passed in the use of bronchoscopic instruments for training both the eyes and the hands in the many delicate adjustments and manipulations necessary for the development of a satisfactory technic.
Cadaveric material and living dogs not being easily available, Jackson2 has recommended the use of a specially prepared rubber tube to simulate the trachea which is held fast in a small iron vise, providing a simple, always at
