RASCL: Electromechanical Catheter

Project Summary

The RASCL project, sponsored by Nextern, aims to develop a disposable electromechanical catheter for precise surgical procedures, with the goal of reducing radiation exposure by allowing doctors to operate from behind a barrier. This device will feature a motor-controlled actuator, enabling precise bending of the catheter tip for enhanced accuracy during surgical procedures. RASCL will provide end users, namely medical professionals, with more precise surgical input without fatigue to the user, whilst also being suitable for delicate procedures in constricted environments.

Design Goal

The goal of this project is to design an electromechanical catheter that will be used in surgical procedures. The catheter will contain a linear range of motion to bend a catheter tip in all directions.

Design Constraints

• Cost within the range of $50 - $100
• Incorporate a linear actuator as the main mechanism for motion.
• Repeatable design, for easy manufacturability and assembly consistence with minimal ariations.
• Actuator stroke length of 1 inch which is the maximum distance the actuator travels when fully extended.
• Withstand a load of 80 Newtons without failure.
• Self-locking to hold the applied load without external force.
• Housing for all components to not exceed 2 inches in diameter and 8 inches in length.
