  • Patent number: 11944403
    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.

  • Patent number: 11850093
    Abstract: In one embodiment of the invention, a robotic surgical system includes a combined laser imaging robotic surgical tool, a control console, and a laser generator/controller. The tool is mounted to a first robotic arm of a patient side cart. The tool has a wristed joint and an end effector coupled together. The end effector has a laser-emitting device to direct a laser beam onto tissue in a surgical site and an image-capturing device to capture images of the tissue in the surgical site. The control console, in communication with the tool, receives the captured images of tissue in the surgical site and displays the captured images on a display device to a user. The laser generator/controller is coupled to the tool and the control console to control the emission of the laser beam onto tissue of the surgical site.

  • Publication number: 20230372033
    Abstract: Minimally invasive surgical methods employ an offset drive shaft to actuate an end effector. A minimally invasive surgical method includes introducing an end effector to an internal surgical site. The end effector includes an end effector base that is coupled to the instrument shaft via a wrist. An end effector articulation mechanism is operated to reorient the end effector base relative to the instrument shaft. A surgical task is performed by operating a motor to rotate an offset drive shaft relative to the instrument shaft to actuate the end effector.

  • Patent number: 11717370
    Abstract: A surgical instrument includes a proximal control mechanism. The proximal control mechanism has an opening through which a resilient latch arm can be inserted to engage a locking surface of a fixed latch structure contained within the proximal control mechanism. The resilient latch arm is contained entirely within the proximal control mechanism when engaged. A release channel extends from an outer periphery of the proximal control mechanism to the resilient latch arm entrance opening. The release channel provides a passage through which a release tool can be inserted to engage the resilient latch arm and provides a fulcrum for the release tool where the release channel is joined to the outer periphery of the proximal control mechanism. The surgical instrument can be released by prying the resilient latch arm away from the locking surface of the fixed latch structure with the release tool used as a lever on the fulcrum.

  • Publication number: 20230240775
    Abstract: Implementations relate to actuated grips for a controller. In some implementations, a controller includes a central member, a grip member coupled to the central member and moveable in a grip degree of freedom, a shaft coupled to the grip member, and an actuator coupled to the shaft and operative to output an actuator force on the shaft. The actuator force causes a grip force to be applied via the shaft to the grip member in the grip degree of freedom.

  • Publication number: 20230200792
    Abstract: A method of engaging a medical instrument with a medical instrument manipulator comprises receiving an indication that a first input coupling of the medical instrument is positioned adjacent to a first drive output of the manipulator. The first drive output is driven by a first actuating element. In response to receiving the indication, the first drive output is rotated in a first rotational direction. A determination is made, by one or more processors, as to whether a resistance torque is experienced by the first actuating element after rotating the first drive output in the first rotational direction. If the resistance torque is not experienced by the first actuating element after rotating of the first drive output in the first rotational direction, the first drive output is rotated in a second rotational direction.

  • Patent number: 11627948
    Abstract: A medical system includes a control system and an instrument manipulator. The instrument manipulator is configured to receive an instrument and includes a first drive output and a first actuating element configured to drive movement of the first drive output. The first drive output is configured to drive a first input coupling of the instrument. The control system is configured to receive an indication that the first input coupling of the instrument is positioned adjacent to the first drive output of the manipulator, in response to receiving the indication, command the first actuating element to cause movement of the first drive output, receive a feedback associated with a force experienced by the first actuating element during the movement of the first drive output, determine an instruction signal for the first actuating element based on the feedback, and transmit the instruction signal to the first actuating element.

  • Publication number: 20220361975
    Abstract: A medical instrument comprises an instrument control surface configured to mate with an instrument sterile adapter to receive input drive forces through the sterile adapter to control actuation of the surgical instrument, the instrument control surface comprising a first opening defined in the instrument control surface. A latch structure of the instrument comprises a locking surface configured to engage a latch arm in response to the latch arm being received in the opening, wherein in an engaged state of the latch arm with the locking surface the medical instrument is attached to the instrument sterile adapter and the latch structure prevents movement of the latch arm in a first direction. A latch release is moveable in the engaged state of the latch arm with the locking surface to exert a force causing movement of the latch arm in a second direction to disengage the latch arm from the locking surface.

  • Patent number: 11446105
    Abstract: An instrument sterile drape includes a plastic sheet and an instrument sterile adapter (ISA) coupled to the plastic sheet. The ISA includes bottom and top plates located on opposite sides of the plastic sheet plate and joined together. A passage in the bottom plate allows an instrument carriage flux connection to pass through the plastic sheet and the bottom plate to be adjacent to the top plate. The top plate includes a signal transmission area that will be adjacent to an upper surface of the flux connection of the instrument carriage. A flux connector may close an opening in the signal transmission area of the top plate and provide a path for an electrical or optical signal. The signal transmission area of the top plate may be thinned to allow an RFID sensor to be closer to an RFID device in a surgical instrument attached to the instrument sterile adapter.

  • Patent number: 11389259
    Abstract: A surgical instrument includes a proximal control mechanism having an instrument control surface. The instrument control surface has two openings through which two resilient latch arms can be inserted to engage a fixed latch structure contained within the proximal control mechanism. The fixed latch structure provides two lead-in ramps that force the resilient latch arms onto locking surfaces. The resilient latch arms are contained entirely within the proximal control mechanism when engaged. Inward forces can be applied to two buttons to apply an outward force on the resilient latch arms and release them from the locking surfaces of the fixed latch structure. Each of the two buttons is accessible from one of two opposite outside surfaces of the proximal control mechanism.
