  • Patent number: 11317977
    Abstract: A method for using a surgical instrument comprises actuating a movable valve member at a first time using robotic action and actuating the valve member at a second time using manual action. The instrument comprises the valve member, a robotic actuation piece, a chassis, a transport shaft coupled to the chassis, a cavity extending through the transport shaft, and a valve. The chassis is adapted to be mated with a robotic manipulator. The valve comprises the valve member, a manual button coupled thereto, and a valve channel. The valve member is configured to translate across the valve channel along an axis. Robotic actuation comprises rotating the robotic actuation piece around an axis perpendicular to the axis of the valve member. Manual action comprises translating the manual button parallel to the axis of the valve member. The robotic actuation piece remains engaged with the valve member during the manual action.

  • Publication number: 20220105336
    Abstract: A suction/irrigation medical device comprises a valve body having one or more conduits fluidically coupled thereto and a first channel extending through the valve body. The medical device also comprises a first valve plunger disposed along the first channel and configured to move along an axis to open and close the first channel. The first valve plunger has a first opening to permit a fluid to flow through the first channel. The medical device also comprises a second valve plunger disposed along the first channel and along a second channel to couple the second channel into the first channel when the second valve plunger is in a first position. The second valve plunger has a second opening that has at least one dimension that is greater than a corresponding dimension of the first opening of the first valve plunger.

  • Patent number: 11224733
    Abstract: A suction/irrigation medical device valve system comprises a first valve plunger configured for insertion into a first valve plunger channel. The first valve plunger has a first latch member disposed at a distal end with a first sealing member and a first valve opening disposed proximally from the first latch member. The system also comprises a second valve plunger configured for insertion into a second valve plunger channel. The second valve plunger includes a second valve opening that is longer than the first valve opening. The system also comprises a valve body having the first and second valve plunger channels. The first and second valve plunger channels are configured to receive the first and second valve plungers, respectively.

  • Publication number: 20210353373
    Abstract: A medical device includes a shaft, a beam, a hard stop structure, and a link. A proximal end portion of the beam is coupled to the distal end portion of the shaft and a distal end portion of the beam is coupled to the link. A strain sensor is on the beam. A hard stop structure includes a proximal end portion, a distal end portion, and first opposing stop surfaces. The proximal end portion of the hard stop structure is coupled to a distal end portion of the shaft, and the distal end portion of the hard stop structure is coupled to the link. The first opposing stop surfaces are positioned to limit a lateral range of motion of the distal end of the beam with reference to the proximal end of the beam in a first direction by the first stop surfaces contacting one another.

  • Publication number: 20210322118
    Abstract: An apparatus includes a housing, a cable guide, a first cable, and a second cable. The housing is coupled to a shaft of a medical instrument. The cable guide is coupled to the housing, and defines a shaft opening into a passageway defined by the shaft. A first guide groove and a second guide groove are defined by the cable guide, with each of the first guide groove and the second guide groove being splayed outward from the shaft opening. The first cable is routed within the first guide groove and through the shaft opening, and is configured to slide within the first guide groove. The second cable is routed within the second guide groove and through the shaft opening, and is configured to slide within the second guide groove.

  • Publication number: 20210137627
    Abstract: An instrument sterile adapter couples a surgical instrument and an instrument carriage. The instrument sterile adapter includes an instrument plate that provides a first surface to receive the surgical instrument and a latch plate joined to the instrument plate. The latch plate includes a second surface to receive the instrument carriage and latch structures. Each latch structure has a carriage latch arm that extends away from the second surface of the latch plate and an instrument latch arm joined to the carriage latch arm. The instrument latch arm extends through the instrument plate and away from the first surface of the instrument plate. A connecting member flexibly connects the carriage latch arm and the instrument latch arm to a remainder of the latch plate. The connecting member may be perpendicular to the latch arms. The latch arms may engage fixed locking surfaces in the instrument carriage and the surgical instrument.
