Why Instrument Identification Is Tested on the CIS Exam
The Certified Instrument Specialist (CIS) exam heavily tests surgical instrument identification. As a CIS-certified technician, you are expected to recognize instruments by sight, know their proper care, and identify defects during inspection.
Most Commonly Tested Instrument Categories
Forceps and Clamps
- Adson Dressing Forceps — fine tissue forceps with or without teeth
- Babcock Forceps — atraumatic grasping of delicate tissue
- Mosquito Clamp (Halstead) — small hemostatic clamp, curved or straight
- Mixter Forceps — right-angle forceps for dissection and clamping
- Gemini Forceps — right-angle clamp with a fine tip
- Profunda Clamp — vascular clamp for femoral artery procedures
Scissors
- Mayo Scissors — heavy, blunt-blunt for cutting heavy tissue or suture
- Metzenbaum Scissors — long and delicate for fine tissue dissection
- Iris Scissors — small, fine scissors for ophthalmic procedures
- Potts-Smith Scissors — angled vascular scissors
- Tenotomy Scissors — fine scissors for tendon work
Retractors
- Army-Navy Retractor — S-shaped, hand-held, double-ended
- Senn Retractor — small double-ended retractor with rake end
- Richardson Retractor — large abdominal retractor
- Deaver Retractor — curved blade for deep abdominal retraction
- Weitlaner Retractor — self-retaining with sharp prongs
- Gelpi Retractor — self-retaining with sharp single prongs
Needle Holders
- Mayo-Hegar Needle Holder — standard, heavy duty
- Castroviejo Needle Holder — fine, for ophthalmic suturing
- Webster Needle Holder — small, for plastic and delicate procedures
- Derf Needle Holder — small, lightweight needle holder
Elevators and Chisels
- Freer Elevator — double-ended, used in ENT and orthopedic procedures
- Key Elevator — periosteal elevator for bone surgery
- Lambotte Osteotome — for cutting bone
- Bone Curette — spoon-shaped for scraping bone
Suction Devices
- Yankauer Suction — oral/pharyngeal suction tip
- Poole Suction — abdominal suction with perforated guard
How to Study Instrument Identification Effectively
1. Use Visual Flashcards
Instrument identification is a visual skill. Study with images, not just names. Our CIS practice questions include instrument photos for every identify-the-instrument question.
2. Learn by Category
Group instruments by type — forceps, scissors, retractors, needle holders. Learning within categories helps you distinguish similar-looking instruments.
3. Know the Key Features
For each instrument, know:
- What it looks like (tip shape, jaw style, overall profile)
- What it's used for (surgical specialty and purpose)
- How it's tested (cotton tip, leather, plastic dowel)
4. Know Your Testing Materials
The CIS exam tests instrument functionality. Know which testing material matches which instrument:
- Scissors — yellow non-latex (small), red non-latex (large), index card
- Needle holders — suture material
- Bone curettes — leather
- Osteotomes/chisels — plastic dowel rod
- Nail nippers — leather
- Knives — yellow non-latex testing material
Common CIS Instrument Inspection Points
- Box lock — should move smoothly without wobbling
- Ratchet — should hold on first ratchet without releasing
- Jaws — should meet evenly with no gaps
- Scissor blades — should cut cleanly through full blade length
- Tips — should meet perfectly without crossing or gapping
Stain Identification for CIS Exam
| Stain Color | Likely Cause |
|---|---|
| Brown/orange | Saline contact, inadequate rinsing |
| Blue-gray | Cold sterilization solutions |
| Black | Ammonia, certain medications |
| Multicolored | Ammonia contact |
| Pitting | Saline, rust |
