The invention relates to a device and a method for displaying the axis of astigmatism of an eye, in which an observation unit is used to observe the eye and, using a display unit, the orientation of the axis of astigmatism of the eye is displayed. A sensor unit generates sensor data which indicate a modification to the alignment of the observation unit relative to the eye. A calculation unit updates the displayed orientation of the axis of astigmatism with the aid of the sensor data, and issues it as the current orientation of the display unit.

One example method for detecting events during a surgery includes receiving surgical video of a surgery comprising a plurality of video frames; identifying, by a first trained machine-learning (“ML”) model, an event during a surgical procedure based on the surgical video; determining, by the first trained ML model, a subset of the plurality of video frames, the subset of the plurality of video frames corresponding to the event; determining, by a second trained ML model, a characteristic of the event based on the subset of the plurality of video frames; and generating metadata corresponding to event based on the characteristic of the event.

Provided are systems and methods for weight-based registration of location sensors. In one aspect, a system includes an instrument and a processor configured to provide a first set of commands to drive the instrument along a first branch of the luminal network, the first branch being outside a path to a target within a model. The processor is also configured to track a set of one or more registration parameters during the driving of the instrument along the first branch and determine that the set of registration parameters satisfy a registration criterion. The processor is further configured to determine a registration between a location sensor coordinate system and a model coordinate system based on location data received from a set of location sensors during the driving of the instrument along the first branch and a second branch.

A surgical instrument is disclosed comprising a housing and a control circuit mounted to and/or embedded in the housing.

Example embodiments relate to surgical systems. The system includes an end-effector assembly having an instrument. The system includes a first arm assembly. A distal end of first arm assembly is securable to the end-effector assembly. The system includes an elbow joint assembly. A distal end of elbow joint assembly is secured to a proximal end of first arm assembly. A proximal end of elbow joint assembly is secured to a distal end of second arm assembly. The second arm assembly includes a first elbow drive assembly. The first elbow drive assembly includes an integrated motor for driving the elbow joint assembly to pivotally move the first arm assembly relative to an axis. The second arm assembly also includes a second elbow drive assembly. The second elbow drive assembly includes an integrated motor for driving the elbow joint assembly to pivotally move the first arm assembly relative to another axis.

A control method for a robot system is provided. The robot system includes a plurality of motion arms, and the plurality of motion arms include a first motion arm and a second motion arm. The control method includes: determining a motion mode of ends of the first motion arm and the second motion arm of the robot system, where the motion mode includes synchronous motion of the ends of the first motion arm and the second motion arm; determining motion paths of the first motion arm and the second motion arm based on the motion mode and a relative end pose relationship between the first motion arm and the second motion arm; and controlling, based on the corresponding motion paths, the first motion arm and the second motion arm to move.

Example embodiments relate to systems for performing a surgical action. The system includes an instrument assembly transitionable between insertion and non-insertion configurations. Instrument assembly includes an instrument arm having a shoulder section, first and second arm sections, wrist section, and end effector section. A second end of the securing portion is secured to a first end of the shoulder section. Instrument assembly is in the insertion configuration when: the shoulder section, first arm section, second arm section, and end effector section are arranged along a central axis; and a distance between the end effector section and second end of the securing portion is greater than a distance between the shoulder section and second end of the securing portion. Instrument assembly is in the non-insertion configuration when the shoulder section, first arm section, second arm section, and/or end effector section are not arranged along the central axis.

Embodiments relate to surgical devices, systems, and methods. The system includes a port assembly and surgical arm assembly. The port assembly includes a main body having a main channel. The main channel includes a left channel portion, right channel portion, left anchor channel portion, and right anchor channel portion. The left channel portion is shaped in such a way that, when a surgical arm of the surgical arm assembly is inserted through the left channel portion, a movement of the surgical arm is restricted to be a movement within the left channel portion and along a first central axis. The right channel portion is shaped in such a way that, when the surgical arm is inserted through the right channel portion, a movement of the surgical arm is restricted to be a movement within the right channel portion and along a second central axis.

Medical software tools platform utilizes a surgical display to provide access to specific medical software tools, such as medically-oriented applications or tools, that can assist those in the operating room, such as a surgeon or surgical team, with a surgery. In particular, an optical sensor located within an endoscopic camera may register subtle differences in color characteristics reflected from a tissue surface and in turn transmit the information to a medical image processing system. Moreover, the new tools are intended to help surgeons better determine the boundaries between healthy and diseased regions during surgical procedures. Various tools are intended to be used in procedures where indocyanine green (ICG) fluorescent dye is used. Intraoperative fluorescence imaging is commonly used during minimally invasive procedures to enable surgeons to visualize tissue perfusion and anatomical structures. The term perfusion refers to the passage of blood and tissue fluid through the capillary bed. Intraoperative fluorescence imaging can also be used to improve visualization of vessels and structures, which, in turn, may reduce the risk of complications during minimally invasive surgeries.

Example embodiments relate to surgical systems. The surgical system includes a port assembly and instrument arm assembly. The port assembly includes a central access channel, anchoring portions, and anchor channels. The instrument arm assembly includes a shoulder section, first arm section, shoulder joint portion, elbow joint portion, second arm section, wrist section, end instrument, and instrument arm anchor segment. The instrument arm anchor segment includes an anchor body and instrument arm anchor portion. The anchor body is secured to the shoulder section. The anchor body is inserted through one of the anchor channels. The instrument arm anchor portion secures to one of the anchoring portions when the anchor body is housed in one of the anchor channels. The central access channel remains as an open access channel through the port assembly when the instrument arm anchor portion is anchored to one of the anchoring portions.
