Figure 3: Diagrammatic depiction of the mechanics involved in grasping the smooth spherical foreign body with the jaws of the forceps. (1) Bronchial wall, (2) Bronchial mucosa with varying degrees of edema depending upon duration of foreign body and its nature (organic vs. inorganic), (3) Intra-bronchial passage, (4) Smooth, spherical foreign body; necklace bead intended to be depicted in the figure, and (5) Optical alligator foreign body forceps. (A) Direction of forceps applied by the closing jaws of the optical alligator foreign body forceps. (B) The equator of the spherical foreign body. It may be noted that the jaws will rarely reach beyong the equator. The airway is narrow and limits the permissible size of the jaws and their width. (C) The foreign slips the grasp and is displaced distally as a result of cumulative effect of the forces applied by the jaws of the forceps. The smooth surface and the spherical shape both predispose to such an event
