Douglas Trocar and Cannula 3mm

Clinical Application

Small-diameter access for minimally invasive procedures where low-profile ports are required. Primarily used to establish a 3 mm working channel for diagnostic laparoscopy, fine endoscopic instruments, and select gynecologic interventions. The Douglas designation indicates suitability for procedures involving access to the rectouterine (Douglas) pouch and other pelvic targets where careful, atraumatic entry with a narrow port is advantageous. The 3 mm size is commonly chosen for pediatric cases, office-based procedures, or when minimizing trocar-site trauma and scarring is a priority.

Design & Configuration

The instrument is configured as a matched trocar (obturator) and cannula pair. The narrow 3 mm cannula provides a low-profile conduit for micro-instruments while reducing soft-tissue displacement at the port site. A closely fitting obturator stabilizes the assembly during insertion and protects the cannula lumen from tissue occlusion until the port is established. This configuration supports controlled entry and instrument exchanges with minimal tissue disruption, which can reduce postoperative discomfort and lower the risk of port-site complications compared with larger-diameter ports.

Instrument Specifications

• Set composition: trocar (obturator) and matching cannula
• Nominal diameter: 3 mm
• Intended access: percutaneous minimally invasive access for laparoscopy and gynecologic procedures
• Reusable design for repeated sterilization and clinical use

Material & Construction

Constructed from medical-grade stainless steel to provide the strength and corrosion resistance required for repeated clinical use. Precision machining ensures concentric alignment of obturator and cannula for smooth insertion and reliable instrument passage. Reusable construction supports standard sterile processing and inspection protocols between cases.

Quality & Compliance

Manufactured by FDA-registered OEM facilities and produced under strict quality control standards.

Brand Comparison

Comparable in form and function to equivalent instruments offered by major US medical suppliers.
