System for Determining the Orientation of a Bone-Implanted Anchor

A method for simplifying the process of designing a platform for minimally invasive surgery. The platform is designed to attach to a set of bone-implanted anchors attached to the patient. This method makes the fitting of the platform to the anchors simpler and easier.

System for Determining the Orientation of a Bone Implanted Post

A method for determining an orientation of a base to which a fiducial marker is detachably mounted. The method includes the steps of determining the axis of symmetry for the fiducial marker and choosing the determined axis of symmetry of the fiducial marker as the axis of symmetry of the base.

Transductive Access Catheter

The tissue of the human body is separated by planes separated by minimal fluid, and it is often desirable to enter into the space between these planes to perform procedures including delivery or removal of fluid/therapeutics. Accurately and harmlessly placing catheters within these planes is very difficult because of the very close proximity of the tissues -- often within 1mm. The Transductive Access Catheter System solves these problems by allowing the operator to insert a shallow beveled needle into the space of interest using a hollow inner catheter that is filled with saline to probe much like a micro water hammer to detect difference in resistance to flow at the tip of the catheter. The primary competing technology uses suction to pull on the outer tissue which increases the target space volume at the catheter; however this has limitations of tissue rigidity and thickness (PerDUCER, Comedicus). Due to the versatility across disciplines, a wide variety of applications for this catheter exist, which include: Pericardial Space Infusion or Drainage, Pleural Space Infusion or Drainage, Subdural and Epidural Infusion, and Intraocular Fluid Space Infusion or Drainage.

Pulsed Infrared Light for the Inhibition of Central Nervous System Neurons

Vanderbilt researchers have developed a novel method for contactless simulation of the central nervous system. This technique involves the use of infrared neural stimulation (INS) to evoke the observable action potentials from neurons of the central nervous system. While infrared neural stimulation of the peripheral nervous system was accomplished almost a decade ago, this is the first technique for infrared stimulation of the central nervous system.

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.
