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.

Algorithms for Contact Detection and Contact Localization in Continuum Robots

This technology enhances the capabilities of continuum robots by not only detecting contact during movement but also estimating the position of the contact during the movements executed by the robot. An algorithmic feedback loop can then constrain the movement of the robot to avoid damage to its robot arm, damage to another robot arm or damage to surrounding structure. 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.

Summary

This technology enhances the capabilities of continuum robots by not only detecting contact during movement but also estimating the position of the contact during the movements executed by the robot.

Wireless Tissue Palpation for Minimally Invasive Robotic Surgery Techniques

Researchers in Vanderbilt University's STORM Lab have developed a wireless palpation device that uses magnetic coupling between two units to provide valuable feedback about tissue properties and potential abnormalities. The wireless capabilities of this technology make it ideally suited for minimally invasive surgery and natural orifice procedures, as the device does not require the use of a surgical port.

A Robotic System for Real-time Tumor Manipulation During Image Guided Breast Biopsy

Three types of technologies have been developed for assisting during breast biopsy procedures.<br><br>1) Many robotic systems have been developed to improve accuracy of needle insertions. Butthese systems do not compensate for tumor movement during the insertion. Hence multipleinsertions are typically required to successfully sample the tumor.<br>2) Steerable needle devices have been developed to guide the needle tip towards the tumor.Even though these systems may not require multiple insertions, they cause tissue damageinside the breast during steering of the needle.<br>3) Finite element methods have been developed to predict and compensate for tumormovement. The disadvantage with this technology is that geometric and mechanicalproperties of the breast are required for finite element analysis. The average computationaltime is approximately half an hour.<br><br>We developed a novel technology for guiding clinical breast biopsy. This system positions a tumor inline with the needle during real-time needle insertion procedures. This technology solves the following problems:<br><br> - Breast biopsies can be performed without multiple needle insertions<br> - Expedites breast biopsy procedures<br> - Does not need geometric or mechanical properties of the breast<br> - Tissue damage inside the breast is minimized<br>

Summary

Early detection of breast cancer, the most common cancer among American women and the second most deadly, has been proven to reduce mortality by about 20% to 35%. In order to diagnose a patient with breast cancer, a sample of tissue must be taken for analysis.
