A surgical system used to determine the presence of a vessel 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 (), and at least one light sensor () disposed at the working end () of the surgical instrument () and configured to receive light emitted from the at least one light emitter () and reflected from the region (), the at least one light sensor () adapted to generate a signal comprising a first pulsatile component and a second non-pulsatile component. The system also includes a controller () coupled to the at least one light sensor (), the controller () comprising a splitter () to separate the first pulsatile component from the second non-pulsatile component and an analyzer () to determine the presence of the vessel within the region () proximate to the working end () of the surgical instrument () based on the first pulsatile component.

System to differentiate and identify types of tissue within a region proximate to a working end of a surgical instrument

A surgical system includes at least one light emitter generating light at a first intensity and an array of light sensors including a least one row of light sensors, individual light sensors in the row of light sensors adapted to generate a signal including a non-pulsatile component. The system also includes a controller coupled to the array of light sensors, the controller including an analyzer to determine the magnitudes of the non-pulsatile components at the individual light sensors in the row of light sensors, to determine if the non-pulsatile component transitions from a higher magnitude to a lower magnitude and from a lower magnitude to a higher magnitude, and if so, to determine if the first intensity should be changed to a second intensity.

System and method for determining vessel size

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 configured to emit light of two different wavelengths. The system also includes at least one light sensor disposed opposite the at least one light emitter, the at least one light sensor configured to detect light at the two different wavelengths and to provide a signal having a pulsatile and a non-pulsatile component for each wavelength. The system further includes a controller coupled to the at least one light sensor and configured to determine and indicate if the vessel is a ureter within the region proximate to the working end of the surgical instrument based on a ratio and a symmetry of a dip in the non-pulsatile component.

System and method used to determine tissue and/or artifact characteristics

A surgical system used to determine a size of a vessel within a region proximate to a working end of a surgical instrument includes at least one light emitter disposed at the working end, an array of light sensors disposed opposite the at least one light emitter, the array comprising a least one row of light sensors, individual light sensors in the row adapted to generate a signal comprising a pulsatile and a non-pulsatile component, and a controller coupled to the array, the controller comprising a splitter to separate the pulsatile component from the non-pulsatile component, and an analyzer to determine the magnitudes of the pulsatile and non-pulsatile components at the individual light sensors, to determine a first peak magnitude and a second peak magnitude of the pulsatile components, and to determine a resting outer diameter of the vessel based on the first and second peak magnitudes.
