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
5
Manufacturing
• Most are stainless steel
– Carbon, chromium, iron, alloys
• High carbon makes instruments harder and less likely to wear
• Chromium increases resistance to corrosion
6
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
7
CLASSIFICATIONS
• CUTTING/DISSECTING• GRASPING/HOLDING• CLAMPING/OCCLUDING• RETRACTING/VIEWING• PROBING• DILATING• SUTURING• SUCTIONING• ACCESSARY INSTRUMENTS
8
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
9
CUTTING/DISSECTING
• The term knife and scalpel are interchangeable although typically scalpels have a detachable disposable blade and non-disposable handle and knives refers to non-disposable handle and blade such as an amputation knife
• Scalpels handles sizes include #3, #4, #7, and #9; Beaver blade handle
10
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
11
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
12
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
13
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

Cutting and Dissecting
15
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
16
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
17
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
18
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
19
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
2020
Clamping and Occluding
21
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
22
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
23
RETRACTING/VIEWING
• Viewing instruments are more specialized • Ear speculum; nasal speculum; vaginal
weighted speculum– vaginal retractors
• Endoscopes are also considered viewing instruments
24
PROBING
• Malleable, wire-like instruments that are used for exploration of tubular structures– Fistula probes, lacrimal duct probes, biliary probe,
rectal probes
25
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
26
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
2727
Suctioning
Poole Suction
Yankauer Suction
28
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
29
MICROINSTRUMENTATION
• Used for working under the microscope• Small and delicate• Must be handled with extra care and precision
