Methods and Devices For
The 'Smart Tool' includes a 'Smart Tool Probe' and two processing modules. The Smart Tool Probe is a hand held, wired or wireless, device that a surgeon utilizes for interrogating and identifying a tissue site, such as the entrance to a pedicle. The processing units, an Electro-Optical Control (EOC) Module and a CDS Module, provide control and display capabilities enabling real-time tissue site (such as vertebra bone) interrogation. The Smart Tool Probe utilizes a system of optical fibers that carry the interrogating optical signal sent by the light source(s) and the reflected optical signal back to the optical receivers. The light source(s) and light receivers are located in the EOC Module. The data received from the EOC Module are processed and converted into an image which is displayed on the screen in real-time. The software installed on the machine allows the surgeon to adjust/enhance the image properties to suit the selected requirements. This mode of operation provides interactive image sharpening (to adjust image sharpness), threshold control (to adjust image contrast), segmentation (to delineate the density map in the image), and image calculus (to pin-point the center of a particular region in the image).
