Abstract: A neurosurgery system for probing brain tissue of a patient for tumorous tissue. The system including a suction tool, an excitation source, an optical instrument, and a controller. The suction tool including a suction cannula defining a lumen, an optical fiber configured to transmit fluorescence emitted by the brain tissue; and an indicator configured to selectively emit visible light. An excitation source is configured to emit an excitation light having a wavelength to induce the fluorescence in the tumorous tissue. The optical instrument is coupled to the optical fiber. The optical instrument configured to convert the fluorescence emitted by the brain tissue and transmitted by the optical and configured to determine that the brain tissue is tumorous based on the electrical signal and activate the indicator based on the determination.

Abstract: A neurosurgical method for determining a resection status of a tumor is described. The method includes acquiring a medical image of a human organ including a segmented tumor. The method further includes determining a pose of a suction tool including at least one optical fiber and a navigation tracker. The method further includes generating excitation light for the at least one optical fiber to excite the target area which includes the tumor and a margin area surrounding the tumor. The method further includes receiving collected fluorescence emitted from the target area. The method further includes determining whether tissue in the target area corresponds to the tumor based on the collected fluorescence at the pose of the suction tool. The method further includes displaying the resection status of the target area relative to the medical image.

Abstract: A surgical handpiece system (10) includes a high-speed surgical bur assembly (102) and a surgical handpiece assembly (104). The high-speed surgical bur assembly has a nose tube (17, 106) and a driveshaft (24, 110) at least partially disposed within the nose tube. A cutting tool (18, 114) is coupled to a distal region of the driveshaft. The cutting tool and the driveshaft are configured to rotate relative to the nose tube. The surgical handpiece system comprises a hub (14, 146) and a rotatable drive chuck (30, 34, 172) for alignment and coupling to the nose tube and the driveshaft. A motor (12) is configured to rotate the rotatable drive chuck, the driveshaft, and the cutting tool when the driveshaft is coupled to the rotatable drive chuck.

Abstract: The present invention relates to the field of microfluidics and in particular to methods for detecting microfluidic droplets and particles within droplets, as well as sorting the droplets. These methods allow for quantifying properties and activities of the particles within the droplets. For this purpose, the invention provides microfluidic droplets comprising suitably labelled particles. The invention also provides microfluidic devices and systems having properties which make them particularly suitable for use in the methods of the invention.

Abstract: A method of detecting a tracer compound dissolved in a liquid composition via surface-enhanced spectroscopy includes the steps of: a. optionally, diluting the liquid composition or the separated liquid by mixing with a diluent liquid; b. bringing a sample of the separated liquid into contact with, a spectroscopy-enhancing surface including gold, silver or copper; c. obtaining a Raman spectrum from the sample; and d. calculating, from the spectrum, the concentration of the tracer in the sample relative to the concentration of a second component of the composition.

Abstract: An infant care unit is provided having a patient support platform, an overhead arm and a mounting assembly. The overhead arm is located generally above the platform. The mounting assembly couples the overhead arm to the platform for pivoting movement relative thereto. The pivoting movement is in a second plane that is generally parallel to a first plane which is defined by the platform.
