8 Instruments for Cutting & Dissecting
Every card below is a live entry from our comprehensive instrument library. Tap any card to see alternative names, inspection points, caution notes, and passing technique.
Straight Mayo ScissorCutting suture during closure and when tying off. It is also the scissors for mesh, drains, dressings and other non-tissue items on the field.Cutting & Dissecting
Curved Mayo ScissorCutting and dissecting heavy, tough tissue such as fascia, muscle and large tendons or ligaments.Cutting & Dissecting
Metzenbaum ScissorCutting and dissecting delicate tissue such as peritoneum, the covering of organs, and fat. The tips are also used to spread tissue planes apart before cutting.Cutting & Dissecting
Potts-Smith ScissorsOpening a vessel and extending the incision (arteriotomy or venotomy), and trimming vessel edges, in vascular and cardiac surgery.Cutting & Dissecting
#3 Knife HandleHolds a blade for the skin incision and other fine, precise cuts. Sets often carry two: one blade for the skin and a second, clean one for deeper cutting.Cutting & Dissecting
#3 Long Knife HandleUsed as the deep knife for precise cutting deep in a wound, where a standard #3 handle is too short.Cutting & Dissecting
#7 Knife HandlePrecise cuts deep in a wound or in a narrow space; the thin handle does not block the view, as in the nose or throat. Often loaded with a #11 or #15 blade.Cutting & Dissecting
Stryker DrillDrills, reams and cuts large, dense bone in orthopedic cases such as total hip and knee replacement.Cutting & Dissecting
Telling the near-identical apart.
Nobody confuses a retractor with a suction tip. What costs you time on the Mayo stand is the pairs that look nearly identical in a crowded tray. Every pair comes down to a single distinguishing feature:
Deaver vs. Richardson Retractor
Curved Mayo vs. Metzenbaum Scissors
Crile Hemostat vs. Kelly Forceps
Allis Forceps vs. Babcock Forceps
Needle Holder vs. Hemostatic Clamp
Adson Tissue vs. Adson-Brown Forceps
Would you know it on the back table?
Reading an instrument list is not the same as identifying it in seconds under surgical lights. Our built-in testing system generates questions directly from real cases with authentic photographs and realistic distractors.

The six functional families.
Instrument names become intuitive once you stop memorising them one by one. Almost every basic instrument belongs to one of these six functional groups:
Cutting & Dissecting
Scalpels, scissors, and curettes designed to divide, excise, or incise tissue. The working edge is sharp and must be protected when passing.
Grasping & Holding
Tissue forceps, sponge holders, and tenaculums that manipulate tissue or maintain exposure without slipping.
Clamping & Occluding
Hemostats and vascular clamps that compress blood vessels or hollow lumens to achieve haemostasis and prevent leakage.
Retracting
Handheld and self-retaining instruments that hold wound edges and organs away from the operative field to optimize visualization.
Suturing
Instruments engineered to drive needles, manipulate suture material, or approximate wound margins with clips and staples.
Suctioning & Aspirating
Hollow probes and cannulas attached to vacuum lines to remove blood, smoke, peritoneal fluid, and debris from the surgical field.
Why identification speed matters at the table.
Naming an instrument on a written quiz and handing it across a Mayo stand in under two seconds are two completely different skills. In the operating room, a surgeon will ask for an instrument with their eyes locked on the incision. If you hesitate or deliver the wrong clamp, the operative tempo breaks.
- Pass with purpose and orientation: Ring-handled instruments (scissors, clamps, needle holders) must be placed firmly into the surgeon's palm with the rings down and the tips facing upward or in the direction of intended use.
- Protect the tip: Scalpels (#3, #7) and sharp retractors (Senn, Volkman) should always be handed over with the sharp edge facing away from your hands and the surgeon's fingers.
- Real tables are not clean catalog shoots: On a live back table, instruments sit under lap sponges, reflect glare from surgical lights, and get wet with saline. Learn instruments by their distinctive silhouettes and hinge geometries.

The honest answers.
What is CSTSetup?
A study site and apps for surgical techs and students, made by surgical techs. It has the real back table for 385 procedures, 3,358 instruments with photos, and practice for the CST, TS-C, CRCST, CSPDT, CSFA, NCLEX-RN and NCLEX-PN. Programs use it to teach and students use it to study. You can start free, and Pro opens all of it.
Can I cancel?
Any time, from your dashboard, and you keep Pro until the period you already paid for runs out. No email, no phone call, no retention script.
Does it work on my phone?
One account covers the website and the apps. Study on the bus, review on the unit, and your progress is the same everywhere. It lives on the account, not the device.
I haven't set an exam date yet.
You don't need one. The daily lesson is 10 questions every day, built from what you are due to see again and what you miss most. Add a date later and your home page counts down to it; more practice is there whenever you want it.
What happens to my progress if I stop paying?
Nothing is deleted. Your streak, your history and everything you have mastered are still there if you come back, and the free tier keeps working.
Is this enough on its own?
For the setups and instruments, yes: 385 trays and 3,358 instruments, tested until you are quick with them. For the exam it is practice, written to the exam's official outline, with full timed exams. It does not replace your program's textbook.
Did you assign this 54-instrument list?
The same platform your students use to study instruments runs their complete clinical case logs, attendance, and preceptor sign-offs — scored automatically against AST, NCCT, and CC4SA standards.
Explore the Educator Portal- Automatic case scoring against AST 6th Ed & NCCT requirements
- Preceptors verify and sign off via secure QR codes without logins
- Clinical hours tracking with optional geofencing
