Surgical Equipment Emergencies: A 7-Point Checklist for Faster Troubleshooting

I'm the person who gets called when surgical equipment fails mid-case. Not the manufacturer's service line. Not the vendor rep. Me.

In March 2024, I got a call from the OR: a Conmed Hyfrecator 2000 had stopped working in the middle of a procedure. The surgeon wasn't happy. The staff was scrambling. And we had 36 hours before the next scheduled case that needed that exact unit. Missing that window would have meant a cancelled procedure and a patient waiting another month.

We found the problem in five minutes (thankfully): a loose grounding pad connector. No internal failure. No worn component. Just a cable that wasn't seated properly. A simple pre-procedure check would have caught it.

That call is why I'm sharing this checklist. It's the 7-point sequence I run through in my role coordinating equipment support for a surgical center. Use it when a device fails during a case, right before a case, or when a staff member reports that something "doesn't feel right." If you're a surgical tech, OR manager, or clinical engineer, these steps will help you troubleshoot faster — and know when to stop.

Step 1: Confirm the exact symptoms before you touch the device

When I'm triaging a failed device, the first thing I ask is: what exactly happened? Did it power up but not fire? Is there an error code on the display? Did it stop mid-use or fail to start?

Most people want to start unplugging things right away. I get it — the instinct is to try something. But the symptom points to the cause. A unit that powers on but won't deliver current is a completely different problem from a unit that's completely dead.

The question that helps most: "What did it do the last time it worked, and what did it do when it stopped?" If you can answer that, you're halfway to the root cause.

Step 2: Pull the user manual — and actually open it

This sounds basic, but I've walked into plenty of ORs where no one knew where the manual was. If you use a device regularly, the manual should be within reach. A physical binder. A digital copy on a tablet. Something.

Take the Conmed Hyfrecator 2000 user manual, for example. It includes an error code table and a troubleshooting flowchart that covers the most common failure modes for that unit. Most manufacturer manuals have similar resources — you just have to open them.

And if you don't have the manual on hand? Most manufacturers, Conmed included, post PDFs on their websites. But searching for a manual during a live case is a prevention problem, not an emergency solution.

Step 3: Verify power and physical connections

After 200+ emergency calls, I'd estimate that a third of the "failed" devices I've been asked to fix were actually power or connection problems. Here's the quick check:

• Is it plugged in? Yes, check anyway.
• Is the outlet live? Test with a known-good device or a multimeter.
• Are the power cable, foot switch, and accessory cords fully seated?
• Are there cuts, kinks, or frayed spots on any cable?

The grounding pad connector from the March 2024 case fell into this category. It looked fine from a distance. It wasn't until we traced the full circuit that we found the cracked connector.

Step 4: Run the device's built-in self-test

Most modern electrosurgery and patient monitoring equipment has a self-test routine. The Hyfrecator 2000 performs a start-up self-check. The Conmed AirSeal insufflation system has diagnostic modes too. These tests won't catch every possible issue, but they do catch internal circuitry and firmware problems — and they give you a concrete pass/fail result to report when you call technical support.

Save the result. Note it in the equipment log. A passing self-test shifts the focus to accessories, consumables, or something in the room itself.

Step 5: Inspect accessories and consumables — the step everyone skips

When a device fails, we blame the main unit. But disposables and accessories fail all the time. This is the step most people ignore, and honestly, it's the one that's saved me the most callouts.

For electrosurgery, that means checking the return electrodes, handpieces, connecting cables, and connectors. Are the electrodes within their use-by date? Is the pad making proper contact with the patient? Do the buttons on the handpiece respond consistently?

For laparoscopic instruments — including Conmed's — a "failed" device might actually be a worn trocar seal or a damaged grasper jaw. For patient monitors, a "faulty" unit might just have a swollen battery pack or a loose lead wire. A quick visual inspection catches most of these.

Step 6: Check the equipment history and know who to call

If you've made it through steps 1 through 5 and still haven't found the problem, it's time to escalate. But before you pick up the phone, gather the device history.

Has this unit been serviced recently? Was there a previous error code? When was the last preventive maintenance check? If your facility uses a CMMS — a computerized maintenance management system — pull the record. Joint Commission surveys and NFPA 99 (the Health Care Facilities Code) both emphasize documented maintenance programs, and this is exactly where that documentation pays off.

It also helps to understand what your vendor actually makes. If you're a supply chain manager researching medical device manufacturers, knowing product lines helps you route support calls to the right team. Need a quick Conmed company overview? Here's the short version: Conmed is a medical device company that manufactures surgical instruments, endoscopy systems, electrosurgery devices, patient monitors, sports medicine products, and advanced surgical technologies like the AirSeal system. Their technical service group handles device-specific support — going through the right channel saves time in an emergency.

Step 7: Know when to stop troubleshooting and escalate

There's a limit to what any checklist can fix. Complex systems like robotic surgery platforms are a different category entirely. They involve software, servomotors, and safety interlocks that require manufacturer-trained technicians. I'm not a robotics technician, so I can't speak to repairing those systems. What I can tell you is: don't try.

For any robotic surgery system, call the manufacturer's technical support directly, and have the error codes and device logs ready. The more precise you can be, the faster they can help.

A good rule of thumb across all devices: if you haven't found the problem in 15 minutes, stop troubleshooting and swap in a backup device. Continuing to poke at a device you don't understand can turn a small issue into a major one.

Common Mistakes I've Learned the Hard Way

Skipping the pre-procedure check. The five minutes it takes to power on a device, attach the accessories, and run a quick function test is the cheapest insurance in the hospital.

"Five minutes of verification beats five days of correction." That's been our department's motto since 2023.

It applies to every device category, not just surgical ones.

Not keeping manuals accessible. We now keep digital copies of every device manual on a tablet at each OR station. That change came from about a dozen separate incidents, not one big one.

Using one device's checklist for another. A dental x-ray machine in the oral surgery clinic has completely different failure modes than an electrosurgical unit. Same goes for lab analyzers — if you're unfamiliar, mass spectrometry is an analytical technique used to identify and quantify molecules based on their mass-to-charge ratio, and mass spec instruments need an entirely different maintenance approach. The checklist concept transfers; the specific steps don't.

Not documenting anything. If you fix the issue, log it. If you escalate, log it. Patterns matter. A device that "fails" every month isn't having bad luck; it's telling you something.

I didn't fully understand how much a checklist could save until the grounding pad incident. I assumed "the device is broken" meant the device was broken. Didn't verify. Turned out to be a $12 connector that took five minutes to diagnose once I stopped assuming.

By my rough estimate, this 7-point checklist has saved our department about $18,000 in unnecessary service calls and overtime so far this year. Not bad for a few minutes of verification.
