A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed. The method comprises the steps of gathering data during surgical procedures, wherein the surgical procedures include the use of a surgical instrument, analyzing the gathered data to determine an appropriate operational adjustment of the surgical instrument, and adjusting the operation of the surgical instrument to improve the operation of the surgical instrument.

A surgical system includes an arm extending from the base and having a distal end configured to be coupled to a tool, a first marker coupled in fixed relation to the base, and a tracking system. The tracking system is configured to collect first data indicative of a position of the first marker and collect second data indicative of a position an anatomical feature of a patient. The surgical system also includes a processor configured to calculate a position of the tool relative to the anatomical feature based on the first data and the second data.

A laparoscopic surgery system calibrator and method for using the same are provided. The laparoscopic surgery system calibrator comprises a tool-retaining apparatus and at least one machine. The tool-retaining apparatus is constructed to releasably secure a surgical instrument having at least one fiducial marker thereon. The at least one machine is coupled to the tool-retaining apparatus to pivot the tool-retaining apparatus through a set of poses once the surgical instrument is secured by the tool-retaining apparatus.

Embodiments of the present disclosure generally relate to systems and methods for calibrating light-emitting diode (LED) light engines. The systems and methods described herein include characterizing the performance of a red-green-blue (RGB) LED light engine so as to enable the display of calibrated, dimensionless output values that accurately reflect a perceived brightness of illumination generated by the light engine for a specific output color.

A surgical robot calibration device configured to be used when calibrating a surgical robotic system to perform a minimally invasive procedure through a natural orifice, the surgical robotic system comprising a surgical robotic arm and a surgical instrument having a rigid linear shaft, the surgical robot calibration device comprising a resistive spacer configurable to hold a calibration port in a fixed position spaced from the natural orifice, such that when the calibration port is held in the resistive spacer, the surgical instrument is insertable into the natural orifice via the calibration port to enable a fulcrum about which the surgical instrument pivots whilst the surgical instrument is inserted into the calibration port to be determined.

A technique for determining a need for a re-registration of an optical patient tracker with medical image data of a patient is presented. A camera system is configured to generate camera image data for tracking the tracker. The camera system comprises an acceleration sensor configured to generate inertial data indicative of an acceleration of the camera system. A method implementation of the technique comprises the following steps performed by a processor: receiving image data from the camera system and analyzing the received image data for a positional change of the tracker indicative of at least one of a drift of the tracker and an impact on the tracker; receiving inertial data acquired by the acceleration sensor and analyzing the received inertial data, or data derived therefrom, with respect to at least one first predetermined condition indicative of an impact on the camera system; and generating, in case a positional change of the tracker indicative of at least one of a drift of the tracker and an impact on the tracker is identified based on the image data and the at least one first predetermined condition is not fulfilled, at least a re-registration signal.

Certain aspects relate to systems and techniques for surgical robotic arm admittance control. In one aspect, there is provided a system including a robotic arm and a processor. The processor may be configured to determine a force at a reference point on the robotic arm based on an output of a torque sensor and receive an indication of a direction of movement of the reference point. The processor may also determine that a component of the force is in the same direction as the direction of movement of the reference point, generate at least one parameter indicative of a target resistance to movement of the robotic arm, and control the motor, based on the at least one parameter, to move the robotic arm in accordance with the target resistance.

Various surgical systems are disclosed. A surgical system can include a surgical robot and a surgical hub. The surgical robot can include a control unit in signal communication with a control console and a robotic tool. The surgical hub can include a display. The surgical hub can be in signal communication with the control unit. A facility can include a plurality of surgical hubs that communicate data from the surgical robots to a primary server. To alleviate bandwidth competition among the surgical hubs, the surgical hubs can include prioritization protocols for collecting, storing, and/or communicating data to the primary server.

A surgical instrument comprising a staple cartridge and at least two independent antenna arrays configured to communicate with the staple cartridge.

A catheter device includes a tube, and an extracorporeal unit coupled to a proximal end of the tube. An implant includes a series of anchors and a tether. The series of anchors includes a first anchor and other anchors, arranged along the extracorporeal unit. Each of the anchors includes a tissue-engaging element, and a head that defines an eyelet. The tether extends, along the extracorporeal unit, through the eyelet of each of the other anchors to the first anchor such that (i) the first anchor is advanceable, with a distal end of the tether, distally into and through the tube toward the tissue, and (ii) subsequently, the other anchors are slidable, sequentially, over and along the tether, distally into and through the tube toward the first anchor. Other applications are also described.
