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 engineers have designed and built a device that improves the accuracy of image-guidance systems (IGS) during surgery. The device creates a custom,  non-slip fit over the head and provides a rigid platform for attaching optical tracking markers to the patient, which is a critical component of image-guided neurosurgical procedures. The device can be used to improve the accuracy of IGS in other areas of the anatomy as well.

Vanderbilt researchers have developed an integrated system ("I-Wire") for the growth of miniature, engineered 3D cardiac or other muscle or connective tissues and their active and passive mechanical characterization. The system utilizes an inverted microscope to measure the strain when the tissue constructs are laterally displaced using a calibrated flexible cantilevered probe.

Vanderbilt researchers have developed an image guidance system that aims to reduce the revision rate for breast conserving surgeries through the use of intraoperative tumor location. The platform integrates MRI imaging, optical tracking, tracked ultrasound, and patient specific biomechanical models to provide a superior tumor localization end result.
