Minimally invasive device for extracting stones from the urinary tract, biliary system, and gastrointestinal tract of various livestock and companion animals. Designed for stone retrieval in dogs, cats, pigs, cattle, sheep, and other common farm and pet species, including bladder stones, urethral stones, bile duct stones, and gastrointestinal stones.

3. 3Retrieval: Pull the handle backward to open the basket and capture the stone. The rotating version allows you to turn the handle to adjust the retrieval angle.
4. 4Remove stone: Push the handle forward to close the basket and grasp the stone, then slowly withdraw it in a steady motion to minimize tissue injury.
