Esaote LA523 Biopsy Needle Guide (ESM-012) — Replacement

Biopsy guides like the Esaote LA523 Biopsy Needle Guide (ESM-012) 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.

When to replace the guide

• Any crack in the bracket or channel, however small
• Loose or unreliable locking 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

• 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.
• Quote the reference number printed on the guide or bracket, if legible.
• 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.
