When soft, friable substances, such as a bolus of
meat, become impacted in the upper esophagus, the short mechanical
spoon (Fig. 30) used through the esophageal speculum is of great aid
in their removal. The blade in this instrument, as the name suggests,
is a spoon and is not fenestrated as is the safety-pin closer, which
if used for friable substances would allow them to slip through the
fenestration. A longer form for use through bronchoscopes and
esophagoscopes is shown in Fig. 36.
A laryngeal curette, cautery electrodes, cautery handle, and laryngeal
knife are illustrated in Fig. 34. The cautery is to be used with a
transformer, or a storage battery.
