Biopsy guides like the INNOFINE JSM-389 Reusable Biopsy Needle Guide for Samsung CA1-7S / CA1-7SD are replaced rather than repaired – the bracket geometry and needle channel must stay within tolerance, and a worn or damaged guide should come out of service. Use this page to confirm fit before ordering a replacement.

Why biopsy guides are replaced rather than repaired
Guides take repeated mounting, sterilization and needle passes. Wear accumulates in the attachment points and needle channel, and there is no economical way to re-machine a worn guide back into tolerance. Replacement is the standard practice.
This reference is listed for the following probe(s): Samsung: CA1-7S, CA1-7SD. Bracket geometry differs even between visually similar probes, so the pairing above is the starting point – not proof of fit.
When to replace the guide
- Visible cracks anywhere on the bracket or needle channel
- The guide no longer clicks or locks firmly onto the probe
- The needle channel is worn, scored or lets the needle wander
- Deformation after autoclaving or disinfection
- Discoloration combined with brittleness of the material
Confirm fit before ordering a replacement
- Photograph the probe’s full manufacturer and model label and send it with the request.
- Photograph the current guide or bracket, including the attachment point on the probe.
- State the guide or bracket reference if it is printed on the part.
- State the needle gauges you work with and whether reusable or disposable is required.
- Note your sterilization or disinfection workflow so the right configuration is offered.
Similar probe names do not prove that two brackets are interchangeable – the attachment geometry and channel spec decide fit, so compatibility is confirmed against your exact probe label.
Ordering a replacement guide with a probe repair
If the probe itself is also damaged, mention it in the same request – a probe repair and a replacement guide can be assessed and quoted together, which is usually faster than handling them separately.
The illustration is representative and is not a photograph of this exact guide. This record does not claim OEM authorization or universal fit. Compatibility, included components, availability and commercial terms are confirmed in writing for the exact probe and guide reference.
