Abstract: A surgical tool includes a drive housing, a shaft extending distally from the drive housing, a distal seal arranged at a distal end of the shaft, and a flush tube extending from the drive housing within the shaft and terminating proximal to the distal seal. A flushing fluid conveyed distally through the flush tube is discharged from the flush tube and impinges upon the distal seal. A proximal drain is arranged within the drive housing and in fluid communication with an annulus defined between the flush tube and an inner wall of the shaft. The flushing fluid discharged from the flush tube circulates proximally within the annulus to the proximal drain to be discharged from the drive housing.

Abstract: A surgical tool for a robotic surgical system includes a tool housing having a mounting portion for releasably securing the surgical tool to a carriage of the robotic surgical system, tool circuity included in the tool housing and configured to communicate with corresponding circuitry of the robotic surgical system, and an indicator provided on the tool housing and electrically connected to the tool circuitry. The indicator is activatable upon communicably coupling the tool circuitry with the corresponding circuitry of the robotic surgical system, and the indicator provides a visual indication of remaining useful life of the surgical tool.

Abstract: 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.

Abstract: A surgical tool that includes a drive housing, an elongate shaft that extends from the drive housing, and a plurality of drive cables extending within the elongate shaft between the drive housing and an end effector coupled to a distal end of the elongate shaft. A cable brake assembly is at least partially arranged within a cavity defined in the drive housing or the elongate shaft, the cable brake assembly having one or more brakes and a brake pad engageable with one or more of the plurality of drive cables. The cable brake assembly is actuatable between a first position, where the plurality of drive cables are free to move longitudinally within the elongate shaft, and a second position, where the one or more brakes and the brake pad engage and prevent the one or more of the plurality of drive cables from moving.
