Surgical Suction Apparatus
Whenever a surgical procedure is performed,
sterile instruments are essential. Since it is not
possible to sterilize all parts of the suction apparatus
attached to the dental unit, it is necessary to modify it
with a sterile surgical suction apparatus. In some cases,
you may use a mobile suction unit that also uses similar
items. These items are composed of the hose, handle,
and tips. The hose is used to connect the handle to the
suction apparatus and has a sterile tubing that is
available in various lengths. The handle has a bulbous
portion on one end and a chuck on the other end. The
bulbous portion is slipped into one end of the hose, and
the chuck holds the tips. There are several tips
available ranging from #1 to #4. The smaller #2 is
suitable for use in a tooth socket. When these parts are
properly joined and the loose end of the tubing is
connected to the suction, they function as a single
suction unit (fig. 5-2). Your job is to connect the parts,
operate the suction, and manipulate the handle and tip.
With experience, you should be able to perform these
tasks quickly and efficiently to keep the surgical site
clear for the dentist.
There are different kinds of retractors, but the
purpose is the same for each. Retractors are used to
hold back objects in the oral cavity.
tissue retractors hold tissue flaps away from the
treatment site to provide better visibility. Some
retractors have forklike prongs, as shown in figure 5-3.
This allows the handling of the tissue without causing
