C04690: Curved Navigation for Percutaneous SurgeryNovelty:
A new approach to improve accuracy of needle placement during percutanous procedures. This technology also provides access to regions of the body that were previously unreachable by traditional means.
Value Proposition:
Needle placement, given its prominence in surgical procedures, remains a critical aspect in medical treatment. Placement accuracy is especially important for diagnostic biopsies and therapeutic injections, where there is a specific region of interest. However, current methods require straight line trajectory or hand-operation, which inhibit not only the efficacy but also the range of percutaneous procedures. This technology provides a method to control the needle direction after insertion in order to improve accuracy.
• Corrects for deflection
• Able to navigate around obstacles
• Lower cost than traditional robotic systems
Technical Details:
Johns Hopkins researchers have designed a system that overcomes a number of the challenges that cause error in needle placement. A unique needle design allows for navigation with 6 degrees of freedom, post insertion. With this, the system can accommodate tissue density changes, which is often a large source of error. Finally, the ability to plan curved trajectories around tissue improves accessibility and paves the way to new procedures.
Looking for Partners:
To develop and commercialize the technology as a new platform for percutaneous procedures in the Robotic Surgery market.
