BK Medical 8808
BK Medical · Model 8808
Simultaneous Biplane - Efficient and Confident Prostate Examinations [b]Precise Biopsies with Simultaneous Biplane[/b] [*] The 8808e gives you real-time images of both the sagittal and transverse planes which is invaluable for orientation. [*] Simultaneous images of the sagittal and transverse planes provide a clear indication of correct needle placement for quicker and more confident biopsies. [b]Streamlined Workflow[/b] [*] Save time and effort with the transducer's one touch operation. Switch between views, freeze, print and save without touching the scanner. [*] Slender Design [*] The 8808e's sterile, single-use and reusable needle guides are an integral part of the transducer minimizing patient discomfort.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Image dropout / dead element lines
HighSymptoms: Persistent dark vertical bands or a missing sector in the image that do not move with the anatomy.
Root cause: Failed piezoelectric elements in the array.
Intermittent image with cable flex
HighSymptoms: Image drops, flickers or is noisy when the cable or strain relief is moved.
Root cause: Broken conductors in the transducer cable or at the connector strain relief.
Acoustic lens / membrane damage
MediumSymptoms: Haze, comet artefacts, reduced penetration, visible cut or bubble under the lens.
Root cause: Lens delamination or a puncture letting fluid into the acoustic stack.
Connector pin damage / not recognised
MediumSymptoms: Scanner does not detect the probe or shows the wrong probe, bent or corroded connector pins.
Root cause: Damaged scanner-connector pins or a wet/dirty connector.
Housing seal leak (endocavity / biplane)
HighSymptoms: Fails a pre-use leak test, fluid ingress, erratic elements after reprocessing.
Root cause: Worn housing seal or a crack around the biplane array.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Dropout or dead lines in the image
- Confirm the artefact stays fixed on screen and is not shadowing from anatomy or gel bubbles.
- Clean the lens and re-gel; check for trapped air.
- Try the probe on a second compatible scanner, and a known-good probe on this scanner, to isolate probe vs system.
- Perform the pre-use electrical leak test.
- If the probe is confirmed faulty, return it to BK Medical for repair - do not open the housing.
Symptom: Image drops when the cable is moved
- Flex the cable along its length and at both ends while imaging a phantom.
- Inspect the connector pins for damage and the cable jacket for cuts.
- Confirm the connector is dry and fully latched.
- If the fault tracks the cable, return the probe to BK Medical.
- Have an electrical-safety test done after any repair before clinical use.
