  • Vessel detector and method of detection
    Patent number: 10251600
    Abstract: A surgical system used to determine if a vessel is within a region proximate to a working end of a surgical instrument includes at least one light emitter disposed at the working end of the surgical instrument, the at least one light emitter adapted to emit light of at least two different wavelengths. The system also includes at least one light sensor disposed at the working end of the surgical instrument opposite the at least one light emitter, the at least one light sensor adapted to detect light at the at least two different wavelengths. The system further includes a controller coupled to the at least one light sensor and adapted to determine a ratio of the light absorbed at the least two different wavelengths, and to indicate if an artifact within a region proximate to the working end of the surgical instrument is a vessel based on the ratio.

  • Surgical Tool With Integrated Sensor
    Publication number: 20150066000
    Abstract: An instrumented surgical tool and associated systems and methods for performing surgical procedures such as tissue dissection or ligation using the instrumented surgical tool are described. In particular, a surgical tool operatively connected to a sensor used to detect a structural artifact such as the presence and characteristics of a blood vessel and to evaluate the safe use of the surgical tool within a surgical field is described.
