Removal of a closed safety pin presents no difficulty if it is grasped
at one or the other end. A grasp in the middle produces a toggle
and ring action which would prevent extraction. When the
safety pin is open with the point downward care must be exercised
not to override it with the bronchoscope or to push the point through
the wall. The spring or near end is to be grasped with the side-curved
or the rotation forcep
(Figs. 19, 20 and 31) and pulled into the
bronchoscope, thus closing the pin. An open safety pin lodged point up
presents an entirely different and a very difficult problem. If
traction is made without closing the pin or protecting the point
severe and probably fatal trauma will be produced. The pin may be
closed with the pin-closer as illustrated in Fig. 37, and then removed
with forceps. Arrowsmith's pin-closer is excellent. Another method
(Fig. 87) consists in bringing the point of the safety pin into the
bronchoscope, after disengaging the point with the side curved
forceps, by the author's inward rotation method. The forceps-jaws
(Fig. 21) devised recently by my assistant, Dr. Gabriel Tucker, are
ideal for this maneuver. As the point is now protected, the spring,
seen just off the tube mouth, is best grasped with the rotation
forceps, which afford the securest hold. The keeper and its shaft are
outside the bronchoscope, but its rounded portion is uppermost and
will glide over the tissues without trauma upon careful withdrawal of
the tube and safety pin. Care must be taken to rotate the pin so that
it lies in the sagittal plane of the glottis with the keeper placed
posteriorly, for the reason that the base of the glottic triangle is
posterior, and that the posterior wall of the larynx is membranous
above the cricoid cartilage, and will yield. A small safety-pin may be
removed by version, the point being turned into a branch bronchial
orifice. No one should think of attempting the extraction of a safety
pin lodged point upward without having practiced for at least a
hundred hours on the rubber tube manikin. This practice should be
carried out by anyone expecting to do endoscopy, because it affords
excellent education of the eye and the fingers in the endoscopic
manipulation of any kind of foreign body. Then, when a safety pin case
is encountered, the bronchoscopist will be prepared to cope with its
difficulties, and he will be able to determine which of the methods
will be best suited to his personal equation in the particular case.
[FIG. 86.--Schema illustrating the upper-lobe-bronchus problem,
combined with the mushroom-anchor problem and the author's method
for their solution. The patient being recumbent, the bronchoscopist
looking down the right main bronchus, M, sees the point of the tack
projecting from the right upper-lobe-bronchus, A. He seizes the point
with the side-curved forceps; then slides down the bronchoscope to the
position shown dotted at B. Next he pushes the bronchoscopic
tube-mouth downward and medianward, simultaneously moving the
patient's head to the right, thus swinging the bronchoscopic level on
its fulcrum, and dragging the tack downward and inward out of its bed,
to the position, 1). Traction, as shown at C, will then safely and
easily withdraw the tack. A very small bronchoscope is essential. The
lip of the bronchoscopic tube-mouth must be used to pry the forceps
down and over, and the lip must be brought close to the tack just
before the prying-pushing movement. S, right stem-bronchus.]
