A disposable stone extraction basket is a medical device used primarily in urology to remove kidney stones or other foreign bodies from the urinary tract. It is typically used during minimally invasive procedures, such as ureteroscopy or endoscopic stone extraction. The basket is designed to capture and remove stones from the kidney, ureter, or bladder without the need for open surgery.

Key Features:

1. Disposable: As the name suggests, the device is meant for single use, which helps reduce the risk of infection and eliminates the need for sterilization after use.
2. Material: The basket is made of flexible, fine metal wires (often stainless steel or nitinol), allowing it to expand and contract when manipulated by the surgeon.
3. Design:
   • The basket can be deployed in a closed, collapsed form, and once it reaches the target area, it can be opened to "trap" or "snare" the stone.
   • The surgeon can maneuver the basket to capture the stone and extract it carefully through the urinary tract.
4. Endoscopic Guidance: The basket is typically used in conjunction with an endoscope, which provides a visual guide for the surgeon to locate and remove the stone.

Procedure:

1. Insertion: During a ureteroscopy, a flexible or rigid endoscope is inserted through the urethra and into the urinary tract.
2. Deployment: Once the stone is located, the surgeon deploys the basket through the endoscope's working channel.
3. Stone Capture: The basket expands to enclose the stone, and with gentle manipulation, the stone is pulled out of the body.
4. Extraction: The stone is removed, and the basket is discarded after use.

Common Uses:

• Ureteral stones: Stones located in the ureter that need to be removed to prevent blockages or further complications.
• Renal stones: Small kidney stones that have moved into the urinary tract and can be removed without invasive surgery.
• Foreign bodies: Removal of objects accidentally lodged in the urinary tract.

Advantages:

• Minimally invasive: Reduces recovery time compared to open surgery.
• Single-use: Ensures cleanliness, lowers infection risk.
• Flexible design: Can capture stones of various sizes and shapes.
