Wisonic S4-2 Biopsy Needle Guide (JSM-026) — Replacement

Biopsy guides like the Wisonic S4-2 Biopsy Needle Guide (JSM-026) 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

Unlike the probe itself – where lenses, cables and connectors are routinely rebuilt – a guide is a single precision part. Once its bracket or channel is worn or cracked, tolerances are gone and the guide should be replaced, not patched.

When to replace the guide

• Any crack in the bracket or channel, however small
• Loose or unreliable locking onto the probe
• A worn or scored channel that no longer tracks the needle cleanly
• Warping or distortion after reprocessing
• Discoloration combined with brittleness of the material

Confirm fit before ordering a replacement

• Send a clear photograph of the complete probe manufacturer and model label.
• 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.
• Specify the needle gauge range and whether you need a reusable or disposable configuration.
• 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.
