The A.R.M.A. Laboratory of Vanderbilt University has developed a novel continuum robot design enabling multi-scale motion at the macro and micro scale. The unique design allows miniaturization with minimal added cost thereby potentially giving rise to a new generation of surgical robots capable of both macro-motion for surgical intervention and micro-scale motion for cellular-level imaging or intervention. Micro-motion is achieved through a unique method for altering the equilibrium pose of the robot via material re-distribution throughout the length of the robot. This process ushers in a new class of surgical robotics termed continuum robots with equilibrium modulation (CREM).

This device is designed to assist physical therapists in collection of objective data during gait analysis, to facilitate appropriate assistive gait device prescription, to provide patients and therapists feedback during gait training, and to reduce wrist and shoulder injuries with cane usage.Currently gait characteristics are "measured" in a clinic-based atmosphere. This has two limitations: (i) subjective allocation of "measures" of gait characteristics and (ii) limited data based on trials in the clinic ONLY. What this technology is designed to do is achieve freedom from both of these limitations. The measurements are objective and numerical values (force etc.) and the clinic could provide the cane to the user for obtaining a much more extensive data set including use during normal life activities at home etc.

This invention presents a robotic wrist and gripper that operate with three independent degrees of freedom (yaw, pitch and roll) for increased dexterity in minimally invasive surgical procedures. This is the smallest robotic wrist of its kind, and due to its size and unparalleled dexterity, this wrist enables complex surgical maneuvers for minimally invasive procedures in highly confined spaces. Examples of surgical areas benefiting from use of this wrist include natural orifice surgery, single port access surgery, and minimally invasive surgery. In particular, the proposed wrist allows for very high precision roll about the longitudinal axis of the gripper while overcoming problems of run-out motion typically encountered in existing wrists. Thus this wrist is particularly suitable for extreme precision maneuvers for micro-surgery in confined spaces.

Vanderbilt presents an intraoperative device for taking the guesswork out of whether or not a threaded component is securely affixed to bone. This device is an anchor driver that automatically releases upon proper seating of the anchor on the bone of interest.
