Trackerless Image-Guidance Using a Surgical Microscope

Researchers at Vanderbilt have developed a new image-guided, trackerless surgical microscope system to be used in soft tissue surgeries. The current method is to use a surgical microscope along with an image-guided system. This new design eliminates the need for a separate image-guidance system; the entire guidance environment can be realized within the microscope environment.

Image Guidance System for Breast Cancer Surgery

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.

Model-based Compression Correction Framework for Ultrasound

Vanderbilt researchers have developed a system that corrects for compressional effects in ultrasound data during soft tissue imaging. The system uses tracking and digitization information to detect the pose of the ultrasound probe during imaging, and then couples this information with a biomechanical model of the tissue to correct compressional effects during intraoperative imaging.

Transoral Lung Access Device

Transoral lung access is preferable to traditional needlebasedaccess due to the lower risk of lung collapse. However present bronchoscope-based devices enable access to only a small portion of the lung. The present device is a robotic image-guided bronchoscope to navigate the airway under closed-loop control to the target. IT is designed to provide transoral access to any location in the lung, particularly the hard-to-reach peripheral regions.

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.
