A urology stone punch set is a surgical instrument system used to fragment and remove bladder stones during endoscopic procedures. Key specifications include construction from medical-grade stainless steel, specific diameters ( 22fr) and reusability through autoclaving. Core Components and MaterialsA typical urology stone punch set is a manual, non-sterile/sterile  device made from high-quality, corrosion-resistant materials. 

• Material: Primarily crafted from medical-grade stainless steel to ensure durability and resistance to corrosion from repeated use and sterilization.
• Set Composition: A complete set typically includes:
  • Stone Punch Forceps/Instrument: The main tool with a sharp or fine punch jaw mechanism for grasping and crushing stones.
  • Sheath: An outer tube that provides a stable access channel into the bladder/urinary tract.
  • Obturator (Blind/Visual): A component used to assist in the safe and guided insertion of the sheath into the urinary tract. A visual obturator allows for optical guidance when connected to a camera system. 

Technical SpecificationsSpecifications for stone punch sets can vary by manufacturer and intended use (e.g., cystoscopy vs. percutaneous nephrolithotomy). 

• Diameter/Size: Common sizes include  22fr. The appropriate size is selected based on the procedure and the patient's anatomy.
• Length: A standard length is around 30 cm (or 325mm in some cases).
• Compatibility: Designed to integrate with standard urology systems and endoscopes, such as Storz-type platforms, and often compatible with specific sizes of telescopes (e.g., 4mm 30° telescope).
• Handle: Features an ergonomic design to allow for precision control and single-handed operation, reducing hand fatigue for the surgeon.
• Jaw Mechanism: Designed with a fine, controlled, sharp jaw or tip for effective stone fragmentation and retrieval.
