  • Patent number: 11185380
    Abstract: A device to regulate tension of an actuation element for actuating movement of a surgical instrument includes an elastically deformable body configured to be coupled to the actuation element. The deformable body is configured to elastically deform in response to a state of slack occurring in the actuation element. As slack occurs in the actuation element, the deformable body is configured to divert a path of the actuation element to accommodate the slack so the path of the actuation element differs from an axis the actuation element follows prior to the actuation element developing slack. A force transmission mechanism for a teleoperated surgical instrument includes a chassis, an actuation input mechanism, an actuation element, and a tension regulator coupled to the actuation element to compensate for slack of the actuation element.

  • Patent number: 11098803
    Abstract: Sealing assemblies and methods are disclosed for sealing a surgical instrument having an internal drive shaft subject to lateral displacement. A sealing assembly includes a rigid portion shaped to interface with an instrument shaft of the surgical instrument. A laterally oriented slot is open at a radially perimeter location and configured to receive an o-ring seal via the perimeter location. Apertures are disposed on opposing sides of the slot and open to the slot. The apertures are configured to receive the drive shaft there through and are larger than the drive shaft to accommodate lateral displacement of the drive shaft. The slot includes opposing internal sides spaced to interface with opposed axial surfaces of the o-ring seal. The seal inhibits axial transmission of an insufflated gas and/or bodily fluids while accommodating lateral displacement of the drive shaft.

  • Patent number: 11051788
    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.

  • Patent number: 11045274
    Abstract: An instrument carriage provides control of a surgical instrument coupled to the instrument carriage. The instrument carriage includes a control surface that is coupled to the surgical instrument to provide the control. A detection pin having a first distal end that extends from the control surface is coupled to the instrument carriage. A sensor fixed relative to the instrument carriage detects a position of the detection pin. A carriage controller coupled to the sensor, provides a signal that indicates at least a first state and a second state responsive to a distance between the distal end of the detection pin and the control surface. The signal may indicate if an instrument sterile adapter is coupled to the control surface of the instrument carriage. A third state of the signal may indicate if a surgical instrument is coupled to the instrument sterile adapter.

  • Publication number: 20210121164
    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.
