Abstract
To improve the effectiveness of microsurgical techniques, we have developed a semi-autonomous robotic surgical tool (called the 'Smart Scalpel') as an alternative approach to the treatment of vascular lesions. The Smart Scalpel employs optical reflectance spectroscopy and computer vision to identify and selectively target blood vessels with a focused treatment laser. Since the laser only heats along the diseased blood vessels, collateral damage to adjacent healthy tissue is substantially minimized. The Smart Scalpel also employs rapid real-time feedback analysis for on-line modification of the treatment parameters, quantification of treatment efficacy and compensation for motion tremor. These capabilities allow precise control over the energy dosimetry to achieve optimal treatment result. This paper presents the design of a prototype instrument, methods of the image analysis, and preliminary results with animal models.
