Lithotomy Forceps(Open Surgery)

The biliary stone retrieval forceps (open type), commonly referred to as the basket-type stone retrieval basket, represents a specialized "open" grasping instrument. It operates by deploying and retracting a wire mesh basket composed of multiple filaments to ensnare and extract stones, serving as a critical tool for managing larger, fragile, or multiple stones.

Core Features and Values

· Enveloping Retrieval, Not Grasping: The basket is deployed beyond the stone, then retracted and tightened to completely "envelop" and "capture" the stone. The circumferential force distribution ensures a uniform grip, minimizing the risk of stone fragmentation.

· Superior Handling of Large Stones: The expanded basket offers substantial volume, enabling the retrieval of stones with diameters exceeding that of the bile duct. The stone is deformed through compression and subsequently extracted.

· Ideal for Fragile Stones: The uniform circumferential pressure, as opposed to the point pressure exerted by forceps, significantly reduces the likelihood of fragile stones fracturing during retrieval, thereby preventing residual fragments.

· Effective for Multiple Stones: The basket can sequentially capture multiple small stones, enhancing surgical efficiency.
