PCNL (Percutaneous Nephrolithotomy) suction specifications include features like smooth, anti-corrosive, and durable construction for high performance in stone and fluid evacuation. The suction is designed to be easy to handle during surgery and creates a smooth finish to minimize tissue trauma. While specific pressure settings can vary, a key feature is the ability to create a vortex and actively draw stones into the suction conduit, as described in the context of the Super-mini PCNL system. Key features

• Design: Smooth finish and anti-corrosive material for durability and minimal tissue trauma.
• Functionality: High performance for stone and fluid evacuation.
• Handling: Easy to handle in a surgical setting.
• Advanced systems: Some systems include features like a two-layered metal structure where the space between layers is an irrigation channel, and the central lumen is a suction conduit.
• Negative pressure: The negative pressure can be adjusted by opening or closing a pressure vent.
• Suction action: Active suction helps draw stones and fragments back into the suction conduit for removal. 

Laparoscopic bipolar cable specifications include a 3-meter (or 300cm) length, silicone or polyurethane material for the cable insulation, and bi-directional connectors to link the bipolar forceps to the electrosurgical generator. Key features are compatibility with various laparoscopic instruments, high durability for repeated use and sterilization, and enhanced insulation to prevent electrical leakage. Key specifications

• Length: Commonly 3 meters (or 300cm) for sufficient reach during procedures.
• Material: Silicone or polyurethane is frequently used for its flexibility, durability, and biocompatibility.
• Conductors: The internal structure can be SPC (single-pair cable) with PTFE insulation, with specifications like 7/36 2core often cited.
• Insulation: A multi-layer insulation system is designed to provide protection against electrical leakage and ensure safety. 

Key features

• Connectors: Both ends of the cable have connectors designed for a secure and reliable connection to the bipolar forceps and the electrosurgical generator.
• Compatibility: The cable is designed to be compatible with a variety of laparoscopic instruments, such as forceps and dissectors, from different manufacturers.
• Durability: Made from high-quality materials to withstand repeated use and sterilization processes, such as autoclaving.
• Safety: Features include controlled and targeted energy delivery to minimize damage to surrounding tissue and enhance patient safety.
• Function: Transmits electrical current to the surgical instrument to enable precise cutting, coagulation, and grasping of tissues during a procedure. 

Alligator biopsy forceps are precision medical instruments primarily constructed from high-grade, surgical-grade stainless steel to ensure durability, corrosion resistance, and compatibility with sterilization protocols. They are characterized by their unique wide-opening, alligator-like jaws, which feature serrated or cupped inner surfaces designed to provide a secure and firm grip on tissue samples, thus minimizing slippage and crush artifact during retrieval.
