Olympus BML‑V442QR‑30 V‑System Single‑Use Mechanical Lithotriptor is a medical device used in endoscopic procedures to mechanically crush stones (calculi), especially in the biliary tract, during minimally invasive surgeries. It is designed to be used once and then disposed of, rather than reused.
A Single Use Mechanical Lithotriptor like this model is a manual stone-crushing instrument that:
Is inserted through the working channel of an endoscope (such as during an ERCP procedure) to reach stones inside ducts like the common bile duct.
Has a flexible sheath and a small braided basket or grasping mechanism at the tip.
When the operator retracts or manipulates the mechanism, it contracts around the stone and mechanically crushes it into smaller fragments that can be removed or pass naturally.
Clinical Use
These devices are typically used by gastroenterologists and surgeons during procedures such as:
Endoscopic Retrograde Cholangiopancreatography (ERCP) to treat choledocholithiasis (bile duct stones).
Other endoscopic stone removal procedures where mechanical fragmentation is needed.
