Flexible Metal Canula.—In cases of compression of the trachea fromgoitre or other tumors, it is sometimes necessary to use a very long tube,and under these circumstances a canula which is flexible, but yet suffi-ciently rigid to resist pressure, is most suitable. In Konigs tube thecurved portion is like an ordinary canula, the upper three inches of thedescending part is made of silver wire spirally twisted, and the lowestinch is again a solid tube. This canula has answered its purpose in sev-eral cases. Pocket Canula.—To meet the emergency of sudden suffocation,2 mypocket canula will be found very convenient. It consists of a medium-sized tracheal canula with a hollow pilot or key, which contains a Fig. 105.—The Pocket Canula (largest size): c, canula; w and w, wings, which, when not in use, lieflat against the canula, but which, when ready for service, are brought forward and form the shield; p,pilot, projecting from extremity of canula ; A-, knife, projecting from handle, in order that it may be moreeasily withdrawn ; s, slit in handle, showing how it opens when withdrawn from the canula. The shield is made of two pieces of stout wire, which, when the instru-ment is not in use, bend backward against the sides of the tube.
