All-in-One Safety Trocar (Device) System for Controlled Access to Internal Body Cavities

Accessing internal body cavities for drainage, diagnostic sampling, or device placement is critical in thoracic, abdominal, and pelvic procedures—but current methods are complex and risky. Traditional approaches require multiple instruments and manual steps, increasing tissue trauma, procedure time, and complication rates. Even advanced trocar systems lack integrated safety features and often require separate tools for full cavity access.

Researchers at The George Washington University have developed a next-generation, all-in-one trocar system designed to improve safety, efficiency, and operator control. This handheld device integrates a spring-loaded safety needle, pop-out blade, smooth rod, and hollow tube into a single platform with a trigger and safety lock. The design minimizes tool exchanges and streamlines access, reducing procedural complexity.

This technology is looking for partners to shape the next-generation access device for high growth surgical markets. With integrated safety features and streamlined workflow, this system addresses a significant unmet need in minimally invasive and emergency procedures.

Advantages

• Blunt-first entry reduces risk of over-penetration and protects underlying tissue
• Integrated blade deployment eliminates separate scalpel steps for faster, controlled access
• One-handed operation with safety lock enhances precision and reduces user error
• Visual blade status indicator improves operator confidence and control
• Modular, all-in-one format minimizes setup time and tool changes

Applications

• Thoracic and trauma surgery
• Laparoscopic and peritoneal access
• Interventional radiology and abscess management
• Pelvic or retroperitoneal access in gynecologic and urologic procedures
