● Tunnel needle tube assists in the introduction of catheters, pacemaker leads, and other devices, providing support for critical clinical pathways

● The bending area uses medical-grade high-toughness material, which remains stable after repeated angle adjustments, is not easily broken or deformed, ensuring reliable operation

● The needle tip is finely ground and, combined with bending, can smoothly pass through subcutaneous tissue, reducing damage to surrounding blood vessels and nerves, and lowering the risk of postoperative complications

● The surface of the needle tube is smooth without burrs, and the inner wall remains unobstructed after bending, which does not affect the smoothness of instrument insertion, facilitates postoperative cleaning, and meets hygiene standards
