Grasping Applicator for Surgical Positioning (GRASP)

A team of Vanderbilt engineers and surgeons has developed a novel bone and tissue graft placement device, primarily for use in the nasal and skull base cavities. The device uses a unique grasping technique to provide control and finesse in the placement of such grafts in addition to combining the roles of multiple instruments into a single device. The clinical purpose of this tool is to provide surgeons with an instrument that can grasp, place, and manipulate rigid and non-rigid graft materials in a controlled manner for skull base reconstruction; such control is very desirable in order to recreate a sound bony barrier that separates the intracranial and extracranial spaces.

Low Cost Dexterous Wrists for Surgical Intervention

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.

Robotic Platform for Transurethral Exploration and Intervention

This technology, developed in Vanderbilt University's Advanced Robotics and Mechanism Applications Laboratory, uses a minimally invasive telerobotic platform to perform transurethral procedures, such as transurethral resection. This robotic device provides high levels of precision and dexterity that improve patient outcomes in transurethral procedures.

Steerable Needles: A Better Turning Radius with Less Tissue Damage

A team of Vanderbilt engineers and surgeons have developed a new steerable needle that can make needle based biopsy and therapy delivery more accurate. A novel flexure-based tip design provides enhanced steerability while simultaneously minimizing tissue damage. The present device is useful for almost any needle-based procedure including biopsy, thermal ablation, brachytherapy, and drug delivery.

Non-Robotic Dexterous Laproscopic Instrument with a Wrist providing seven degrees of freedom

Inventors at Vanderbilt University have developed a non-robotic dexterous laparoscopic manipulator with a wrist providing seven-degrees-of-freedom. It provides an interface which intuitively maps motion of the surgeon's hands to the tool's "hands". The novel user interface approach provides a natural mapping of motion from the surgeon's hands to the instrument tips.

Algorithms for Compliant Insertion and Motion Control of Continuum Robots

This technology enables continuum robots (aka snake robots) to precisely navigate the intricate structures of deep anatomical passages during minimally invasive or natural orifice surgery. Collateral surgical damage is minimized by the force sensing capabilities of the algorithms used.

Collapsible Lightweight Portable Leg Holder for Ultrasound Guided Lateral Popliteal Block Procedures

A Vanderbilt team led by anesthesiologist Dr. Rajnish Gupta has developed a collapsible, lightweight and portable patient leg positioner for secure and stable leg positioning during ultrasound guided nerve block anesthetic procedures.

Sliding Mode Control System for Steerable Needles

A team of Vanderbilt engineers has developed an advanced control system that is a first-ever 3D control system for delivering a bevel-based steerable needle to its intended target. The controller is also useful for (a) following a desired curved path through tissue; (b) accurately placing the needle tip at the physician's desired target, and (c) reaching obstructed targets using non-straight paths. Experiments in phantom tissue and ex-vivo liver have validated the concept. Experiments with targets that move due to tissue deformation have also been successful.

KidSense Car Seat Safety System for Unattended Child Detection and Temperature Monitoring

A Vanderbilt engineering senior design team has developed a car seat safety attachment that detects if a child has been left unattended in a car seat and if the environment has become uncomfortably hot or cold. The system is designed with a graduated alarm system based on "alert states" that provides a combination of visual, tactile and audio alerts.
