Krause Trocar and Cannula 5.5mm

Clinical Application

This trocar and cannula assembly provides a controlled access port for minimally invasive procedures that require small-caliber instrumentation. At 5.5 mm, it is intended for use with 5–6 mm laparoscopic instruments and scopes, offering a low-profile working channel for tissue manipulation, camera insertion, suction/irrigation, and accessory passage. The device facilitates safe peritoneal entry and subsequent instrument exchanges while maintaining pneumoperitoneum.

Design & Configuration

The cannula serves as a stable conduit through which instruments pass, while the trocar (obturator) creates the initial entry. Key clinical considerations include a smooth inner lumen for atraumatic instrument exchange, a secure hub for temporary instrument stabilization, and a profile that minimizes soft-tissue strain at the port site. A well-mated trocar and cannula reduce insertion force and help control tissue trauma during entry and removal.
