Wisonic L15-4B Biopsy Needle Guide (JSM-040) — Replacement

The Wisonic L15-4B Biopsy Needle Guide (JSM-040) is a positioning accessory, not a repairable device: when a guide is cracked, worn or no longer locks onto the probe, the correct action is replacement. This page helps you confirm the right replacement for your exact probe.

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.

When to replace the guide

• Any crack in the bracket or channel, however small
• 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
• Brittle, discolored material that flexes differently than new

Confirm fit before ordering a replacement

• Send a clear photograph of the complete probe manufacturer and model label.
• Include photos of the existing guide or bracket and where it clips onto 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.
• Confirm sterilization or disinfection requirements in the request.

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.
