The single-use veress needle is a specialized instrument employed in laparoscopic surgery for establishing and maintaining pneumoperitoneum. Its sterile, single-use packaging eliminates the risk of cross-contamination while ensuring optimal sharpness and functional reliability for each procedure. Designed to meet the highest safety standards, the device's core mechanism lies in the synergistic interaction between its blunt-tipped stylet and sharp trocar, which effectively detects tissue penetration layers, thereby preventing accidental injury to intra-abdominal organs and major blood vessels. This instrument serves as the primary safety gateway for initiating minimally invasive visualization.
Core Features and Values
1. Classic Safety Blunt-Tip Design: The blunt stylet precedes the sharp outer cannula during penetration. Upon reaching the peritoneal cavity, the stylet automatically protrudes, enveloping the sharp cannula to provide effective protection, significantly reducing the risk of injury to intestinal and vascular structures.
2. Superior Tactile and Auditory Feedback: Surgeons can distinctly perceive two penetration sensations (rectus sheath and peritoneum) during insertion, accompanied by an audible "click" upon peritoneal entry, providing critical confirmation of proper needle placement.
3. Lateral Gas Inlet and Unobstructed Flow Channel: The proximal lateral gas inlet design ensures efficient connection with the insufflation tube. The smooth internal channel facilitates rapid and stable CO2 insufflation, reducing pneumoperitoneum establishment time.
4. Single-Use Design for Safety and Cost-Effectiveness: Eliminates potential risks associated with cross-contamination and incomplete sterilization from reuse. Additionally, it prevents surgical risks caused by instrument wear and blunting, ensuring consistent reliability with each use while eliminating cleaning, inspection, and sterilization costs.
5. Ergonomic Handle Design: The handle is engineered according to hand mechanics, providing comfortable grip and precise force application, enabling surgeons to perform stable and controlled puncture procedures.
