Multi-Imager Compatible Robot for Image-Guided Interventions and Fully Automated Brachytherapy Seed Injector

C04870: Multi-Imager Compatible Surgical Robot

Novelty:

An apparatus that allows for safe and precise interventions in cooperation with preferred imaging techniques.

Value Proposition:

Robotic systems have the potential to expand the field of radiology by augmenting physician manipulations and integrating medical information for diagnostic purposes. Meanwhile, the clinical potential for MRI guided intervention is promising as MR is the preferred method of imaging soft tissue and tumors. However, typical robotic designs contain materials that are unsafe in the MRI environment. Thus, the design and construction of an MRI compatible robot is a challenging engineering task. This technology overcomes that challenge by providing a robot that can perform MRI guided surgeries.

Technical Details:

Johns Hopkins researchers have developed a robot designed for image based percutaneous needle intervention of the prostate gland. The robot is constructed of nonmagnetic and dielectric materials for complete MR compatibility. The system utilizes a pneumatic stepper motor providing the precision required for needle insertion. Originally developed for fully automated brachytherapy seed injector with a controlled seed magazine, the resulting design can be adapted to numerous other procedures

Looking for Partners:

To develop and commercialize the technology as a new device platform in the Robotic Surgery Market.
