INSTRUMENTATION

Concorde Career College
1
Objectives
• Discuss the relationship between
instrumentation, equipment, and supplies and
quality patient care in the OR
• Identify basic instruments by type, function,
classification, and name
2
Manufacturing
• Most are stainless steel
– Carbon, chromium, iron, alloys
• High carbon makes instruments harder and less likely to
wear
• Chromium increases resistance to corrosion
5
Manufacturing
• Three types of finishing
– Highly polished = increased resistance to
corrosion, but increases glare from OR lights
– Satin (dull) = less reflective, reduces glare
– Ebonized = non-reflective, eliminates glare
• Used for laser procedures because it prevents
reflection of laser beam

ACCESSARY INSTRUMENTS
7
CUTTING/DISSECTING
• One or more sharp edges
– Used for incision, sharp dissection, or excision of
tissue
– Include knives, scalpels, scissors, and bone cutting
instruments – osteotomes, curettes, chisels,
gouges, and rongeurs
– May be classified as cutting instruments – saws,
drills, biopsy punches, adenotomes, and
dermatomes
– -tome – refers to a cutting instrument
8
CUTTING/DISSECTING
• The term knife and scalpel are
interchangeable although typically scalpels
have a detachable disposable blade and nondisposable handle and knives refers to nondisposable handle and blade such as an
amputation knife
• Scalpels handles sizes include #3, #4, #7, and
#9; Beaver blade handle
9
CUTTING/DISSECTING
• Disposable blades are made from carbon steel
• Blades should be loaded and removed with an
instrument such as a needle holder
• #10, #11, #12, #12B, #15, #15C, #20, #21, #22,
#23, #25
• Blades fit specific handles - #10, #11, #12,
#12B, #15, #15C blades fit #3, #7, #9 handles
10
CUTTING/DISSECTING
• #20, #21, #22, #23, #25 blades fit on a #4 knife handle
• Any size Beaver blade will fit on a Beaver blade handle
• #10 blades are the most frequently used blades and
should be loaded on a #3 knife handle; do not load
#10’s on a #7 knife handle
• #11, #12, #15 blades are loaded on a #7 knife handle,
although a #15 blade is used on a #3 knife handle for
small skin incisions
11
CUTTING/DISSECTING
• Blades become dull very quickly. 2 or 3 cuts usually
dulls the blade
• The blades have to be changed as needed
• For safety reasons, if the blade has been changed, the
surgeon should be informed that it is a new blade
when passing it
12
CUTTING/DISSECTING
• Scissors
– Tissue scissors, suture scissors, wire scissors, or
bandage scissors
– Tissue scissors should only be used to cut tissue
because others materials will dull them; an
exception would be CV surgeons, they use Metz to
cut the small sutures
– Wire scissors are used to cut wire
– Bandage and straight mayo scissors can be used
on dressings
13
Cutting and Dissecting
14
14
CUTTING/DISSECTING
• In addition to cutting tissue (sharp dissection),
scissors are also used to spread and open
tissue planes (dull dissection)
• Curved mayo scissors are used on heavy tissue
• Metz are used on medium to fine tissue
• Iris, tenotomy, and Potts-smith scissors are
used on delicate tissues
15
CUTTING/DISSECTING
• Examples of specialized scissors
– Potts-smith – ducts, veins, or arteries
– Cushing - dura
– Jorgenson – hysterectomy
– Strabismus, Iris, corneal scissors – eyes
• Scissors have straight and curved blades and
sharp or dull tips
16
GRASPING/HOLDING
•
•
•
•
•
•
•
•
•
Used to grasp or hold tissue for counter traction or manipulation
Forceps – aka pickups or thumb forceps
Forceps are usually used in the non-dominate hand
Forceps have either teeth, serrations or smooth; Vary in length
Adson – smooth, with teeth, or Brown tips; primarily used for skin
closure
Ferris-Smith – used for heavy tissue
Brown, Russian, Gerald, Cushing, bayonet, rat tooth
Allis, Babcock, Kocher - clamps
Bone-holding clamps – ex; Lane, Kern, Lowen, Lewin
17
Grasping/holding
• Designed to manipulate tissue to facilitate
dissection or suturing or to reduce and
stabilize fractured bone during internal
fixation
• Lowman – Turkey claw
• Lane
18
CLAMPING/OCCLUDING
•
•
•
•
Designed to occlude or restrict tissue
Have ringed handles with interlocking ratchets
Straight or curved, long or short, pointed or round
Vascular clamps have atraumatic serrations that are
vertical
• Bulldog clamps are small spring loaded for temporary
occlusion – vascular
• Hemostats are used to occlude bleeders until they can
be ligated
19
Clamping and Occluding

RETRACTING/VIEWING
•
•
•
•
•
Designed for the exposure of the operative site
May be hand-held or self-retaining
Many sizes and designs; sharp or dull tips
Some retractors are malleable
Many hand-held are double-ended with a variation on
each end and usually are mostly used two at a time
21
RETRACTING/VIEWING
• Most commonly used hand-held retractors –
– small wounds - Richardson, Army/Navy, Senn, Ragnell,
• A variety of rakes, skin hooks;
– large wounds – Deaver, Ribbon (malleable), Harrington
• Most common self-retaining retractors
– small wounds – Gelpie, Weitlaner
– large wounds – Balfour, Bookwalter, O’Sullivan-O’Conner
• Many have a variety of attachments
• Some large self-retaining retractors are attached to the
OR table for stabilization
22
RETRACTING/VIEWING
• Viewing instruments are more specialized
• Ear speculum; nasal speculum; vaginal
weighted speculum
– vaginal retractors
• Endoscopes are also considered viewing
instruments
23
PROBING
• Malleable, wire-like instruments that are used
for exploration of tubular structures
– Fistula probes, lacrimal duct probes, biliary probe,
rectal probes
24
DILATING
• Used to gradually dilate a duct or an orifice to
allow introduction of a larger instrument or
open a stricture
• Used from the smallest to largest
– May require lubrication
• Can be single or double ended
– CBD, lacrimal duct, tracheal, urethral, cervical
25
SUTURING
• Used to hold a curved needle
– needle holders, needle drivers
• Choosing an appropriately-sized needle holder
depends on the size of the needle
– the length depends on the depth
– can be curved for deep tissue
• Vary by specialty
– General, ophthalmic, plastic, GYN, vascular,
microscopic
26
Suctioning
Yankauer Suction
Poole Suction
27
27
SUCTIONING
• For the removal of blood and bodily fluids
• Disposable and non-disposable
• Vary by specialty
– Abdominal, ear, neurosurgery, nasal, rectal
• Some suction devices have the ability to coagulate
• Many different lengths for trachea, esophageal, larynx
– these are not typically used in sterile fashion
28
MICROINSTRUMENTATION
• Used for working under the microscope
• Small and delicate
• Must be handled with extra care and precision
