Krause Trocar and Cannula 4.0mm

Clinical Application

This trochar and cannula set provides a 4.0 mm access port for small-bore endoscopic procedures. It is intended to establish and maintain percutaneous access for introduction of scopes, optics, and instrumentation used in diagnostic and therapeutic work in compact operative fields — for example, arthroscopy, ENT endoscopy, and minimally invasive pediatric procedures where a 4.0 mm working port is required. The cannula serves as a stable conduit while the trocar obturator is used to gain initial entry and is withdrawn once access is obtained.

Design & Configuration

The two-piece design separates the penetrating obturator from the cannula so that the sharp or blunt obturator is used only for entry and then removed, leaving the smooth-walled cannula in place. This arrangement minimizes repeated tissue trauma during instrument exchanges and protects optics and working instruments passing through the lumen. A precision fit between obturator and cannula ensures straightforward insertion and secure seating during the procedure.
