The Hitachi Aloka UST-670P-5 is a common candidate for repair rather than replacement. This page lists its typical failure modes, self-checks you can run, and the details a repair lab needs from you.
| Manufacturer | Hitachi Aloka |
|---|---|
| Model | UST-670P-5 |
| Probe type | Endocavity array |
| Compatible systems | Aloka ProSound Alpha 5, Aloka SSD-3500, Aloka SSD-4000, Aloka SSD-5000, Aloka SSD-5500 |
You will usually see the UST-670P-5 running on Aloka ProSound Alpha 5, Aloka SSD-3500, Aloka SSD-4000, Aloka SSD-5000, Aloka SSD-5500. Mention the console model with the fault description – connector and revision differences matter.
For endocavity heads such as the UST-670P-5, reprocessing chemistry is the main enemy – seal integrity and lens condition decide service life more than the electronics do.
Common failure modes for the UST-670P-5
Match what you are seeing against the table below. The right-hand column reflects how faults of this kind typically assess – the actual verdict always depends on the individual probe.
| What you see | Likely cause | Typically repairable? |
|---|---|---|
| Pin damage or corrosion visible in the connector | Connector damage from forced insertion or drops | Usually repairable |
| Split seams or impact marks on the probe body | A drop or knock; housings are routinely replaced or resealed | Usually repairable |
| Fuzzy or noisy image that cleaning does not fix | A worn lens surface or elements beginning to degrade | Case by case |
| Visible nicks, grooves or staining on the lens surface | Wear from use, or chemical attack from disinfectants | Usually repairable |
| Strain relief pulling away from the cable or gone rigid | Flex fatigue where the cable meets the probe or connector | Usually repairable |
| Dark bands or dropout lines in the image | Element dropout, or a conductor break inside the cable | Case by case |
| Noticeably weaker penetration than the paired probe | Ageing elements or lens delamination reducing acoustic output | Case by case |
| Fluid found inside the probe head after a leak test | Seal failure allowing disinfectant ingress | Case by case |
| Failed electrical leakage test | Compromised sealing on an endocavity probe | Case by case |
Check these before you ship the probe
- Compare penetration and uniformity against a known-good probe on the same preset.
- Inspect the lens face under good light for cuts, bubbles, lifting edges or discoloration.
- Photograph the complete manufacturer label – the exact revision matters for parts compatibility.
- Flex the cable gently along its length while imaging – intermittent dropout points to broken conductors.
- Check the strain reliefs at both ends for splits, stiffness or separation from the cable.
- Have the probe leak-tested before further use – fluid ingress worsens quickly and creates a patient-safety issue.
Repair, exchange or replace — which applies to your UST-670P-5
Three paths apply to a failing UST-670P-5: repair (typical for lens, housing, cable and connector damage), exchange (fastest route back to scanning) or replacement (when the acoustic stack is too far gone). The deciding factors are how much of the array still fires, whether the housing is intact and what downtime costs you. Each probe is judged on its actual condition.
What we need to quote your UST-670P-5 repair
- A clear photo of the complete manufacturer and model label on the probe
- A description of the fault: what you see on screen and when it started
- The ultrasound system (console) the probe is used with
- Screenshots or photos of the image problem, if the fault is visual
- Photos of any physical damage – lens, housing, cable or connector
Images shown are representative and are not photographs of an individual unit. Nothing on this page claims OEM authorization or guarantees universal fit. Whether a specific UST-670P-5 can be repaired, and on what terms, is confirmed in writing once the probe has been assessed.
