An imaging probe comprises a camera or endoscope with an external detector array, in which the probe is sized and shaped for surgical placement in an eye to image the eye from an interior of the eye during treatment. The imaging probe and a treatment probe can be coupled together with a fastener or contained within a housing. The imaging probe and the treatment probe can be sized and shaped to enter the eye through an incision in the cornea and image one or more of the ciliary body band or the scleral spur. The treatment probe may comprise a treatment optical fiber or a surgical placement device to deliver an implant. A processor coupled to the detector can be configured with instructions to identify a location of one or more of the ciliary body band, the scleral spur, Schwalbe's line, or Schlemm's canal from the image.

Inductively powered end of life indicators for robotic surgical instruments

A surgical tool harvests power from a robotic surgical system having one or more robotic manipulators when a housing of the surgical tool is installed within a carriage of one of the robotic manipulators. The surgical tool harvests power via inductive coupling between an inductor of the surgical tool and a corresponding inductor of the carriage. The surgical tool may include an indicator that provides a user with an indication of remaining life of the surgical tool. The indicator may be an LED indicator that is illuminated with power generated via the inductive coupling. The indicator may also be an electro-chromic indicator that changes color when exposed to power generated via the inductive coupling. The indicator may also be a photo-chromic indicator that changes color when exposed to light from a light source powered via the inductive coupling.
