Dr. 136 SUSPENSION LARYNGOSCOPY. 2—THE GALLOWS. The gallows is intended to provide a suitable suspension-point. Ihave used it as it stands now, for two years without altering it in anyway. It essentially consists of a column (Fig. G) bearing a horizontalarm (a). The arm extends to the middle of the operating-table. Itmay be fixed higher or lower, forward or backward. The elevation ischiefly adjusted by transposing the column. In addition the horizontalarm may be changed 20 cm. within the column. The forward and back-. FiS. g8. ward motion of the entire contrivance is accom])lished by means of ascrew (b) (compare Figs. 101 and 102). The gallows is screwed to theoperating-table on the right in the maimer shown in Figs. 99 and 116. ^—THE SUSPENSION-1101 IK. The suspension-hook was formerly more sim])le in form. It con-sisted of a straight rod which was curved at the ujtper end in the formof a hook. (Fig. 103 and 104). Compare my essay in Archiv fitrLaryngologie, Vol. 3G, 1912. According to Albrechts investigations,however, it was found necessary to put a joint in the rod (compare ). Within this joint a backward turning of the hook takes placeabout a horizontal axis (compare Fig. 106). This movement is accom- SUSPENSION 137 plished when one turns the thumb-screw clockwise. In this manner thehook may he turned almost to a horizontal ])Osition. The mechanism isbased upon the principle of the endless screw. The portion helowthe joint shows
