Arthrex Continuous Wave III
Arthrex · Model Continuous Wave III
Continuous Wave™ III Arthroscopy Pump The Continuous Wave™ Arthroscopy Pump offers technical innovations that maintain precise joint distention with independent adjustment of in-line pressure and flow levels. New digital technology eliminates pulsing inflow and the autoclavable remote has an added flush button feature. Advantages of the Continuous Wave III Arthroscopy Pump include a new and improved advanced fluid drive system that maintains distention even during aggressive shaver suction and ACL procedures. Fluid turbulence has been virtually eliminated with a new smooth transition from start to stop, maintaining a stable fluid environment with safe intraarticular pressure. A flush control now allows the pump to provide hemostasis at the touch of a button. An improved noise dampening system allows the pump to operate quietly. All of these features come together to provide surgeons and the OR staff with a truly unique and reliable fluid management system.
Key tips
- ·Never defeat or bypass a return-electrode monitoring (REM) alarm to finish a case - it's a direct burn risk.
- ·Verify OR table battery backup - a table that loses power mid-procedure is a real, documented incident type.
- ·Track surgical light lamp-hours rather than waiting for failure - a sudden failure mid-case is avoidable.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Peristaltic / roller pump wear
HighSymptoms: Inaccurate flow, pressure alarm.
Root cause: Worn pump rollers or tubing raceway.
Pressure / flow sensor drift
MediumSymptoms: Reported joint/uterine pressure inaccurate.
Root cause: Pressure transducer calibration drift.
Inflow / outflow valve fault
MediumSymptoms: Fluid deficit alarm, uneven distension.
Root cause: Worn solenoid valve or occluded line.
Tubing set seating fault
LowSymptoms: Leak, or won't prime.
Root cause: Worn cassette seat or cracked fitting.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Pre-case functional check
- ·Electrosurgical return-electrode cable inspection
- ·Table hydraulic / mechanical inspection
- ·Annual electrical safety test and full PM
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Peristaltic / roller pump wear
- Confirm the presentation - typically inaccurate flow, pressure alarm - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: worn pump rollers or tubing raceway.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the peristaltic pump head per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
