INTRODUCTION surgical instrument is a specialized tool or
device, typically made of steel use
during surgery to clamp, cut, dissect, retract, or otherwise manipulate
and/or modify biological tissue.
There are many different kinds of surgical instruments. Some surgical
instruments are designed for use across all types of surgeries, while
others are for specific surgeries. Surgical instruments must
be decontaminated and sterilized between uses to minimize both the
risks of infection and the introduction of foreign material during surgery.
Within hospitals, this is typically performed by a dedicated sterile
services utilizing steam autoclaves among other sterilization methods.

Classifying surgical instruments helps
In memorizing instruments names, and
To be familiar with the basic categories of instruments.
Surgical instruments have specific purposes and may be classified by
their functions most fall into one of four groups.
3
Instruments are classified by their
function
1. Cutting & Dissecting
2. Grasping & Holding
3. Clamping & Occluding
4. Exposing & Retracting
5. Suturing & Stapling
6. Viewing
7. Suctioning

type of surgical instruments
1. Cutting and Dissecting
Cutting instruments Have sharp edges/points.
They are used to dissect, incise,separate, penetrate, or excise tissue.
These instruments should be kept
separate from other instruments, and the
sharp edges should be protected during
cleaning, sterilizing, and storing.
To prevent injury to the handler and damage to the
sharp edges, proper precautions are necessary to
take during the handling and disposing of all
sharps, blades, or scalpels.
This group includes: scissors, knives, biopsy
punches, scalpels (blades), saws, osteotomes,
drills, curettes, needles, chisels, and etc.
Cutting and Dissecting
5
Main function
To cut and dissect Tissue
To cut sutures, clothing, bandages
Where used mostly .General surgery
Lister Bandage Scissors
Used to remove bandages and dressings
Probe tip is blunt; inserted under bandages with relative safet
6
Sharp/Sharp Scissors
Used to cut and dissect tissue
Both blade tips are sharp
Sharp/Blunt Scissors
Used to cut and dissect fascia and muscle
One blunt tip and one sharp tip
Curved Blunt/Blunt Scissors
7
Both blade tips are blunt
Can be curved or straight
Ear Curette
Can have sharp or blunt scraper ends
Used to remove ear wax from ear canal
2. Grasping and Clamping
A clamp is an instrument that clasps tissue between its jaws.
Clamps are available for use on nearly every type of body tissue,
from delicate eye muscle to heavy bone.
The most common clamps are the haemostatic clamps, designed to
grasp blood vessels, crushing clamps, noncrushing vascular clamps etc.
8
Grasping instruments are used to hold and manipulate structures.
Needle holder, tissue forceps, Allis forceps,bone holders, tenacula
(tenaculum, singular) etc. are included in this category
Sponge Forceps
9
Used to hold gauze squares or
sponge to “mop up” the surgical site
Jaws are serrated
Transfer Forceps
When sterile, transfer forceps;
arrange items on sterile tray
transfer items to sterile field
Toothed Tissue Forceps
Used for grasping and holding tissue, muscle or skin surrounding a
wound
Single toothed on one side; fits between two teeth on the other side
10
Plain Thumb Forceps
Used to hold tissue in place when applying sutures
Used to gently move tissues out of the way during exploratory
surgery
Used to insert packing into or remove objects from deep Cavitiey .
3. Exposing and Retracting
Soft tissues, muscles, and other structures should be pulled aside for
exposure of the surgical site.
Exposing and retracting instruments are those that hold tissue or
organs away from the area where the surgeon is working.
Retractors, like clamps, are available for use in all parts of the body.
They may be very shallow, as for skin retraction, or very deep, as for
the retraction of abdominal contents.
Retractors can be handheld or self-retaining
Skin Hook
Flat end is a blunt retractor
11
Three-prong end may be sharp to dull
12
Used to retract small incisions or secure a skin edge for Suturing
Malleable retractors
Malleable retractor is a flat length of low carbon stainless steel, silver
or silver plated copper that may be bent to the desired angle and
depth for retraction.
13
4 Probing and Dilating
A probe is used to explore a structure or to locate an obstruction
14
Probes are used to explore the depth of a wound orto trace the path
of a fistula.
Dilators are used to increase/enlarge the diameter of a lumen, such as
the urethra, uterine cervix, of esophagus.
15
16
Suturing and stapling
Suture material and different types of needles are covered in a separate
article.
However, it is worth mentioning that needle holders are a specific type
of hinged-forceps that are specifically designed to hold suture needles
17
between their teeth . eg skin staplerand steel suture clip stapler
18
Suction
Suction is used to clear the surgical field by removin blood or other
fluids.
The suction tip is attached to a vacuum piping outside of the sterile
field.
19
1. There are many different shapes of suckers (small and fine-
tipped, or large to prevent blockages) depending on the
operation being performed .

HOW TO CARE OF SURGICAL INSTRUMENT
Instruments should be cleaned and dried immediately after use.
If they aren't, water and chemical residue will cause staining.
Manufacturers recommend using distilled water and solutions with a pH
below 10 for cleaning, rinsing, and sterilization.
Always dry and sterilize instruments in an open positi
Here are general safegared when handling and
cleaning your surgical instruments.
Proper care and handling are key to the longevity of your surgical
instruments
Immediately after use, clean and dry your
instruments.
o Residue will cause staining if they are not rinsed right
after the procedure.
o It is recommended that you use warm or cool, distilled
water and solutions with a pH below 10 for cleaning,
rinsing, and sterilization.
o Dry instruments thoroughly to minimize the risk of
corrosion and water spots.
o For instruments such as forceps and scissors, make sure
they are dried in an open position.
o Store instruments in dry areas.
Instruments should be used for their
intended purpose only.
o Make sure you use the appropriate instruments for each
procedure.
21
o Incorrect use can damage the instruments beyond repair
or can impact its performance, which can lead to
frustration and delays in the OR
Don’t place instruments in saline or any other
harsh solution
Long-term exposure to saline can break down the surface of an
instrument which can cause corrosion, thus, shortening its
lifespan.
Use a softer brush for manual cleaning.
o Stiff plastic or nylon brushes are most effective for
manual cleaning.
o You should pay special attention to any hard-to-reach
areas and moving parts.
Lubricate all instruments that have any
metal-to-metal action before autoclaving
o Only use surgical instrument lubricates.
o Using a steel or wire brush will likely damage the
instrument.
o Never use WD-40, oil, or other industrial lubricants.
For instruments such as scissors or needle holders, sterilize them in
an open position
Never lock an instrument during autoclaving this will prevent the
steam from reaching and sterilizing the metal-to-metal surfaces.
Ultrasonic cleaning is one of the most
effective cleaning methods.
o Ultrasonic cleaning is the result of cavitation.
o The vibrate waves create bubbles in the solution which
grow until they finally implode, removing grime.
o Recommended exposure time is 5-10 minutes.
?
How do you care and storesurgical instruments
Don't forget to lubricate all moving parts after cleaning and before placing
them in the autoclave.
Be careful not to exceed the recommended exposure time when using
disinfecting and sterilizing solutions.
22
Store your instruments in dry areas and make sure they're thoroughly dried
before putting them into
If items were sterilized in an unwrapped state, they should be used
immediately.
Alternatively, you can store them in covered, sterile trays for a week or less.
Wrapped instruments should be kept in a cabinet in a warm and dry
environment.
