A reference handbook of the medical sciences, embracing the entire range of scientific and practical medicine and allied science . y hard arteries, thy-mic tracheostenosis, and similar conditions introducean element of danger in bronchoscopy, and aneurjsmis a contraindication except for the removal of foreignbodies. Instruments.—AH bronchoscopes of practical usehave been straight and rigid tubes. The chief dif-ferences in the various forms have been in the methodof illumination. Ivillian in his earlj work used theIvirstein headlamp (Fig. 1152) and he stiU uses it for 532 direct larj-ngoscopy and direct laryngeal Brunings uses a hand lamp attached to theproximal end of the larj-ngeal speculum and thebronchoscopes shde through the larj-ngeal tube, thedistance of extension being regulated by a watchspring (Fig. 1153). Otto Kaliler^ uses a different formof proximal lamp. In all forms of proximsd lampsthe Ught is projected down the tube from the prox-imal end. The author, like Ingals and the majorityof American larjngologists, prefers the distal form ofillumination shown in Fig. 1154. B, in which a very. Fig. 1153.—Bruoings Bronchoscope. The iUuminating appa-ratus, -4, is shown swimg to the left to permit of the insertion ofthe inner tube, B, into the larj-ngeal tube, C. small lamp is carried down to the distal end of the in-strument on a hght carrier. Inasmuch as good workhas been done with all forms of illumination, it isprobable that successful work depends more upon theskill and especiaUy upon the amount of practice ofthe operator and the training of his assistants, thanupon the form of illumination. Various accessoryinstruments are needed, a few of which are the removal of particular foreign bodies manyspecial instruments have been devised, such as pincutters, safety-pin closers, mechanical spoons forfriable bodies, etc. Doubtless manj- more will needto be devised. Each case is a problem in itself, theproblem being not so much the removal
