摘要： A conductor-less, shape-able, surgical lighting system and methods for use in surgical applications in which a medical clinician, once having established a surgical site, can shape the lighting system to selectively illuminate desired volumes of the surgical site. The system includes preselected lengths of an elongate light emitting member formed of a transparent elastomer matrix material having a glass transition temperature of lower than or substantially equal to room temperature to render the elongate light emitting member bendable and shape-able. Embedded in the transparent elastomer matrix material are particles of a transparent material having a refractive index different from a refractive index of the matrix material dispersed in the elastomer matrix material so that light coupled into the elongate light emitting member is scattered and refracted out of the elongate light emitting member along its length. One end of the elongate light emitting member is coupled with a light source.

摘要： The present disclosure provides a conductor-less, shape-able surgical lighting system for use in surgical applications in which a medical clinician, once having established a surgical site, can shape the lighting system to selectively illuminate desired volumes of the surgical site. The system includes one or more preselected lengths of an elongate light emitting member formed of a transparent elastomer matrix material having a glass transition temperature of lower than or substantially equal to room temperature to render the elongate light emitting member bendable and shape-able. Embedded in the transparent elastomer matrix material are particles of a transparent material having a refractive index different from a refractive index of the matrix material dispersed in the elastomer matrix material so that light coupled into the elongate light emitting member is scattered and refracted out of the elongate light emitting member along its length. One end of the elongate light emitting member configured to be coupled to a light source.

摘要： Systems, devices and methods are provided for performing tissue removal and analysis based on the in-situ optical analysis of tissue and of liquid collected from the tissue region. In one example embodiment, a tissue removal and analysis probe includes an elongate tissue removal device, an optical fiber, and a fluid fillable conduit, where distal ends of the optical fiber and the conduit are in communication with an external region that is adjacent to a distal functional portion of the tissue removal device. The results of optical analysis one of both of external tissue and collected fluid may be employed to determine whether or not tissue removal is to be carried out. Various devices may be interfaced with the conduit for optical analysis of the collected fluid. In one example embodiment, the tissue removal device may be movable relative to the optical fiber and conduit.

摘要： A surgical microscope system for use in a medical procedure. The surgical microscope system is controlled in a first mode of operation corresponding to a phase of the medical procedure and defining at least one setting for adjusting a set of adjustable optics. While in the first mode of operation, the surgical microscope system automatically determines, from a captured image, an indication that a second mode of operation is relevant. The mode of operation is switched to the second mode of operation.

摘要： A computing device for tracking surgical imaging devices stores a preoperative image of patient tissue registered to a frame of reference of a tracking system; and receives, from a first imaging device, a first intraoperative image of a first region of the tissue, with a finer resolution than the preoperative image. The computing device receives a position of the first imaging device from the tracking system, and registers the first intraoperative image with the frame of reference. The computing device receives, from a second imaging device, a second intraoperative image of a second region of the patient tissue, with a finer resolution than the first intraoperative image. The computing device registers the second intraoperative image to the first intraoperative image; and controls a display to present the preoperative image overlaid with the first intraoperative image, and the first intraoperative image overlaid with the second intraoperative image.

摘要： Methods and apparatus is provided for use in a medical procedure for image acquisition using a high-resolution imaging system, a three dimensional imaging system and a navigation system. A 3D imaging scan of an imaged portion of the surface of the patient is acquired using the three dimensional imaging system. Then, a first high-resolution imaging scan covering a first sub-portion of the imaged portion is acquired using the high-resolution imaging system, which is tracked by the navigation system. The 3D imaging scan and the first high-resolution imaging scan are combined to create an enhanced three dimensional image having contour lines to provide a visual representation of depth derived from depth information acquired from both the three dimensional imaging system and the high-resolution imaging system. Subsequent high resolution scans may then be stitched into the image and the updated image displayed in real-time.

摘要： A device and method for guided insertion of microelectrodes into tissue is provided. The device includes a flexible optical fiber for optical coherence tomography imaging, a metal layer coating the optical fiber for recording electrical signals and an outer insulation layer coating the metal layer along the optical fiber length. The method includes inserting an optical fiber coated with a metal layer and further coated with an insulation layer into a tissue, collecting intraoperative image data through the optical fiber by optical coherence tomography, receiving the image data on a computer and displaying the image on a monitor, using the image data to determine a location in the tissue, receiving an electrical nerve signal through the metal layer and measuring the electrical nerve signal on a electrophysiological recording system.
