  • Patent number: 11344375
    Abstract: Surgical assemblies, instruments, and related methods are disclosed that control tissue gripping force. A method for controlling grip force in a robotic surgical instrument includes actuating an input link of a spring assembly. An actuation force is transferred from the input link to an output link of the spring assembly. Relative movement is inhibited between the input link and the output link when the transferred actuation force is below a predetermined level with a preloaded spring of the spring assembly. The input link is moved relative to the output link by deforming the preloaded spring when the transferred actuation force increases above the predetermined level. A grip mechanism is actuated via the output link.

  • Patent number: 11191561
    Abstract: The present disclosure provides a method, system, and apparatus that adds rotational functionality to a conventional clot maceration device. The rotational functionality can be imparted by a wide variety of mechanical devices, such as by a hand operated rack and pinion type gear system or an electrically driven motor. An outer member (such as a catheter) of a declotting apparatus may be rotated while an inner member remains substantially fixed in position. The degree of rotation of the inner member may be between 60 and 180 degrees in a clockwise and counterclockwise rotation. In one embodiment, the rotating mechanism is coupled to a sliding and/or lateral mechanism to impart both lateral and rotational movement to the declotting apparatus. The deformable members of a basket or jacket of the declotting apparatus may form a helical structure and/or each comprise a bundled wire.

  • Patent number: 11185623
    Abstract: Frequency-domain signal processing of pressure sensor signals and/or flow signals is used to provide on-demand control of a multi-component fluidic system. An example method, implemented in a phacoemulsification system comprises receiving a signal from each of one or more sensors, the one or more sensors comprising at least one pressure sensor, and converting each of one or more of the received signals, including at least one signal from a pressure sensor, to a frequency-domain representation of the received signal. The method further comprises identifying, based on the frequency-domain representations of received signals, at least one event from a set of predetermined events, and controlling one or more fluid control devices, responsive to the identifying.

  • Patent number: 11172977
    Abstract: A matrix router with frequency switching is provided having an energy source electrically connected to a plurality of interface ports. A switching device is provided between the energy source and the plurality of switches. One of the plurality of interface ports includes a paired electrode interface port for the connection of a paired electrode device thereto. The paired electrode device has a first pair of opposed electrodes and a second pair of opposed electrodes for clamping on tissue. When the paired electrode device is operably connected to the paired electrode interface port and actuated, the switching device alternates energy such as bipolar RF from the first pair of opposed electrodes to the second pair of opposed electrodes.

  • Patent number: 11172823
    Abstract: A computing device for tracking surgical imaging devices stores a preoperative image of patient tissue registered to a frame of reference of a tracking system; and receives, from a first imaging device, a first intraoperative image of a first region of the tissue, with a finer resolution than the preoperative image. The computing device receives a position of the first imaging device from the tracking system, and registers the first intraoperative image with the frame of reference. The computing device receives, from a second imaging device, a second intraoperative image of a second region of the patient tissue, with a finer resolution than the first intraoperative image. The computing device registers the second intraoperative image to the first intraoperative image; and controls a display to present the preoperative image overlaid with the first intraoperative image, and the first intraoperative image overlaid with the second intraoperative image.
