Higher Accuracy Image-Guidance in Surgery

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.

Breast Tumor Margin Detection System Using Spatially Offset Raman Spectroscopy

Vanderbilt University researchers have developed a technology that uses spatially offset Raman spectroscopy to obtain depth-resolved information from the margins of tumors. This helps to determine positive or negative tumor margins in applications such as breast lumpectomy, and the technology is currently being investigated for breast cancer margin detection.

Traveler's Diarrhea Vaccine for Enterotoxigenic E. coli (ETEC)

Vanderbilt researchers are developing a novel vaccine for preventing enterotoxigenic Escherichia coli (ETEC) infection of the gut which causes traveler's diarrhea and childhood death in developing countries. The vaccine uses colonization surface antigens and their constituent proteins to generate an immune response. This prevents infection by blocking the ability of bacteria to adhere to the intestinal mucosa. Mice treated with this vaccine showed significantly reduced disease and bacterial colonization compared to control. Preclinical development of this vaccine is ongoing and includes testing of different adjuvants and routes of administration. ETEC is a leading cause of gastrointestinal disease in developing countries affecting both residents and visitors. Residents in particular are primarily children who suffer high morbidity and mortality from the dehydrating effects of the illness. Visitors include the approximately 800 -- 1000 million people who travel to developing countries each year with 20 -- 60 % of them developing this illness. A commercially available vaccine to inoculate residents and travelers against ETEC would represent a significant opportunity to satisfy an unmet need and improve human health.

Flat-Cut Bit for Cranial Perforator

Inventors at Vanderbilt have developed a novel perforating drill bit for cranial surgery. Deep brain stimlation (DBS) has become a technique for the treatment of movement disorders, as well as obsessive compulsive disorders and epilespy. This cranial drill bit significantly improves the process of preparing the periphery around the cranial punch during electrode implantation, one of the critical steps during DBS surgery.

System and Methods for Contact Detection and Localization in Continuum Robots

This technology expands the capabilities of continuum robots with a system and method that enables them to detect instances of contact and to estimate the position of the contact. This framework allows the motion of the robot to be constrained so as to ensure the robot doesn't damage itself, another robot arm, or surrounding environments. Applications for this technology include enhanced safe telemanipulation for multi-arm continuum robots in surgery, micro-assembly in confined spaces, and exploration in unknown environments.

Compliant Insertion, Motion, and Force Control of Continuum Robots

Vanderbilt researchers have developed a framework for compliant insertion with hybrid motion and force control of continuum robots. This technology expands the capabilities of robotic surgery by providing continuum robots with the ability to autonomously discern, locate, and react to contact along their length and calculate forces at the tip, thus enabling quick and safe deployment of snake-like robots into deep anatomical passages or unknown environments.

Dexterous Robotic Wrist and Gripper for Extreme Precision Micro-surgical Maneuvers in Confined Spaces

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.
