Kirk Nangreaves has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11950866
    Abstract: A system includes a manipulator arm and a cannula mount arm. The manipulator arm includes a link and a locking assembly coupled to the link. The cannula mount arm includes a latch. The cannula mount arm is configured to be extended from the link to an extended position. The locking assembly is configured to engage with the latch when the cannula mount arm is extended from the link to the extended position so as to lock the cannula mount arm in the extended position. Activation of an electrical component coupled to the locking assembly is inhibited when a cannula is docked to the cannula mount arm.
    Type: Grant

  • Patent number: 11331154
    Abstract: A surgical system includes a link of a manipulator arm and a telescoping cannula mount assembly. The link includes a curved end. The telescoping cannula mount assembly is positioned in the curved end of the link. The telescoping cannula mount assembly includes a curved cannula mount arm. In a first state, the curved cannula mount arm is parked within the curved end of the link. In a second state, the curved cannula mount arm extends from the curved end of the link and is locked in an extended position. The telescoping cannula mount assembly also includes a mechanical arm retraction system. The mechanical arm retraction system couples the curved cannula mount arm to the curved end of the link. The mechanical arm retraction system is configured to automatically move the curved cannula mount arm from the second state to the first state.

  • Patent number: 8125806
    Abstract: A multi-stage power supply uses a boost stage and an inverter stage to boost the voltage value of a DC power supply to a desired level, and then convert the power into an AC form. The multi-stage power supply additionally has a controller which can simultaneously control the boost stage and the inverter stage using counter-synchronous signals.
