INSTRUMENTS
CLASSIFICATION BY USAGE
Surgical instruments
are designed to perform
either diagnostic or therapeutic operations; to
locate the cause of a problem, or to treat a
problem once it has been found. Each
instrument is designed to perform a specific
function. Those functions may be generally
categorized under one of the following uses:
1. To cut or incise:
Instruments used for this purpose are
frequently referred to as “sharps”. They include
scissors,
knives,
scalpels,
chisels
and
osteotomes, among others.
2. To retract tissue:
Hand-held and self-retaining retractors serve
this purpose, as well as instruments such as
skin and bone hooks
3. To grasp, hold or occlude:
These include the many types of forceps,
including hemostats, dressing and tissue
forceps, as well as bone holding forceps. Also
included in this group are needle holders
.
4. To dilate or probe:
These instruments are used to dilate or enlarge
openings or to find an area or foreign object.
5. To cannulate or drain:
These instruments including catheters, drains
and cannulas, are generally used to drain a
wound.
6. To aspirate, inject or infuse:
These instruments serve to remove unwanted
fluids as well as to inject needed fluids into a
patient. Among these instruments are
syringes, some needles, trocars and cannulas.
7. To suture or ligate
:
Suture or ligation is used to close or rejoin a
wound or an area of operation, e.g., a vessel,
a nerve or tissue. There are a variety of
sutures and clips, as well as suture needles
and ligating instruments.

l
Clinical Tip:
Because scalpel blades dull rapidly
after being pressed against bone they should be
changed between incisions if more than one flap
is to be reflected.
Periosteal Elevators
Molt # 9 & Woodson
# 1
Seldin
Clinical Tips for periosteal
Elevators
Pry Stroke:
Using the tooth as a fulcrum, the sharp
pointed end of the elevator is used to reflect the MPF by
first prying the IDP free from the underlying bone
.
Push Stroke:
Using the broad end of the elevator in a
push stroke, the attached gingiva and alveolar
mucosa are reflected to the desired extent.
Pull Stroke:
Using the periosteal elevator in a pull
stroke can sometimes shred the periosteum.
Periosteal elevators
are used to reflect mucoperiosteum,
to loosen soft tissue from teeth before extraction, and to
retract small flaps
Tissue Retractors
Seldin
Austin
Minnesota
Tissue Retractors: Clinical
Tips
1. For small flaps, use the periosteal elevator
for retraction
2. For large flaps use Minnesota or Austin
retractor
3. Place retractor beneath the flap resting on
sound bone
4. Avoid trapping of flap between retractor
and bone
5. RETRACT PASSIVELY
: no attempt is made to
pull the flap out of the field

Operating Scissor
SCISSORS
come in a tremendous variety of styles and sizes.
They come in straight, curved and angular versions.
Useful Tips in Usage:
1. The curved patterns are preferred by most surgeons for
dissecting, since they provide a better field of vision for the
areas to be cut.
2. Straight scissors are used when a straight cut is desired,
such as in sutures, nerves, vessels.
3. Scissors are also used to spread and probe the area of
incision (dissection & undermining tissues). The smaller
sizes are used at the surface, the larger sizes deeper in the
cavities.
4. Dedicate the different types for their specific purpose for
example, using fine dissecting scissors to cut suture can
ruin the cutting edge.
5. Special care instructions: To maintain scissors in peak
operating condition, they must be sharpened regularly.

Needle Holders Vs Hemostats
1. Needle holders look similar to hemostats, but jaws
are thicker and shorter.
2. Face of shorter beak of needle holder is crosshatched
to ensure positive grip on needle but hemostat has
parallel grooves that do not allow a firm grip on needle.
Needle Holder: Clinical Tips
Needle holders are available in many styles and sizes.
Shorter ones are used for working close to the surface.
Longer ones are for deeper cavities.
The smaller the needle, the smaller the jaws of the needle
holder.
If the needle is too large to be held securely, select a
larger size needle holder. Otherwise, the needle may slip, or
the needle holder may be overstressed, causing fatigue or
breakage
INSTRUMENTS FOR BONE
SURGERY
Bone Curette:
To curette or remove soft tissue
from bony cavities
Volkmann
Brun
Halle
Bone Curette
Bone File:
for final smoothing of bone before
suturing the MPF back into position
Bone File:
Clinical Tips
1. Use the bone file in a pull stroke, because the
teeth of the file are arranged in such a fashion
to remove bone only in this direction.
2. Avoid cross filing or pushing the bone file,
because this results in burnishing and
crushing of bone.
3. Carefully Cleanse the instrument by wiping the
grooved ends with a sponge. By failure to do
this, dust or chips may easily remain in the
wound.
Bone Rongeur:
to remove bone by
shearing on a planned action
Bone Rongeur: Clinical Tips
1.
Smaller amount of bone
should be removed in each
of multiple bites but never
large amount of bone in a
single bite.
2.
A constant cleansing of
the blades is necessary.
3.
Rongeurs are delicate
and relatively expensive
therefore,
NEVER
remove
teeth with rongeurs.
Chisels and Gouges:
To score, cut, scrape, and sculpt bone
Osteotomes
:
To shape and sculpt bone,
or section a tooth
Chisels:
To cut a window in the bone
cortex for access or to allow harvesting
