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.

Summary

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.

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.

Summary

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.

Rapidly Adjustable Flexible Positioning Arm for Ultrasound Probe -Clinician's Third Hand

A Vanderbilt team led by anesthesiologist Dr. Rajnish Gupta has developed a rapidly adjustable flexible positioning arm that can precisely position the ultrasound probe in such a way that it can be adjusted and fine-tuned with the flip of a switch. Upon fixing the probe in position, both of the clinician's hands are free to perform ultrasound guided procedures without the need for a second person to hold the probe.

Summary

A Vanderbilt team led by anesthesiologist Dr. Rajnish Gupta has developed a rapidly adjustable flexible positioning arm that can precisely position the ultrasound probe in such a way that it can be adjusted and fine-tuned with the flip of a switch.

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.

Summary

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.

Summary

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.

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.

Summary

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.
