摘要： A method performed by a computing system comprises receiving a collected set of spatial information for a distal portion of an instrument at a plurality of locations within a set of anatomic passageways and receiving a set of position information for a reference portion of the instrument when the distal portion of the instrument is at each of the plurality of locations. The method also comprises determining a reference set of spatial information for the distal portion of the instrument based on the collected set of spatial information and the set of position information for the reference portion of the instrument and registering the reference set of spatial information with a set of anatomical model information.

摘要： The technology described in this document can be embodied in a viewing apparatus for a surgical device, the apparatus including a lens assembly including a first polarizer, a display device configured to present an image of a surgical scene, and a reflective surface oriented at an acute angle with respect to the display device such that light from the display device is reflected from the reflective surface towards the lens assembly. The first polarizer in the lens assembly is configured such that light reflected from the reflective surface passes through the first polarizer, and light reaching the first polarizer without being reflected from the reflective surface is substantially blocked.

摘要： A system may comprise a sensing instrument including an elongate flexible member with a channel extending therein. The elongate flexible member may include a proximal portion, a distal portion, and a flexure portion between the distal and proximal portions. The sensing instrument may also include a flexure at the flexure portion of the elongate flexible member, a sensing element coupled at the distal portion of the elongate flexible member, and a flexure control apparatus extending within the elongate flexible member and configured to bend the flexure to change an orientation of the sensing element relative to the proximal portion of the elongate flexible member. The sensing instrument may also include an exit port in the proximal portion of the elongate flexible member.

摘要： An illustrative system includes an image sensor comprising a first pixel, a second pixel, a third pixel, and a fourth pixel. The system further includes a pixel-level broadband infrared cutoff filter that covers the second pixel and that is configured to prevent the second pixel from collecting infrared light having wavelengths included in a first range of wavelengths. The first, third, and fourth pixels are not covered by pixel-level broadband infrared cutoff filters configured to prevent the first, third, and fourth pixels from collecting infrared light having wavelengths included in the first range of wavelengths.

摘要： A computer-assisted surgical system is configured to activate a first mode of operation in which movement of a user control mechanism is translated to movement of a surgical instrument coupled to a manipulator arm; receive, during the first mode of operation, a first user input by way of a user input mechanism associated with the user control mechanism; activate, based on the first user input, a second mode of operation in which the user control mechanism is repositionable without causing the surgical instrument to move; receive, during the first mode of operation, a second user input by way of the user input mechanism, wherein the second user input is different from the first user input; and activate, based on the second user input, a function associated with a third mode of operation different from the first and second modes of operation.

摘要： The present disclosure provides a surgical instrument, such as a tissue sealing instrument, with an elongate shaft and an end effector. The end effector includes a first jaw and a second jaw that includes a staple cartridge with a plurality of staples for engaging tissue. The instrument further includes a drive member for closing the jaws and engaging the staples, and an actuation mechanism, such as a coil, in contact with the drive member. The actuation mechanism is configured to translate the drive member distally through the first jaw (instead of through the staple cartridge as in conventional surgical stapling instruments). Eliminating the internal channel for the actuation coil from the staple cartridge provides more space in the cartridge for the staples, allowing for the use of taller staples and/or a more compact and maneuverable instrument.

摘要： One embodiment of the present invention sets forth a technique for training a machine learning model to perform feature extraction. The technique includes executing a student version of the machine learning model to generate a first set of features from a first set of image crops and executing a teacher version of the machine learning model to generate a second set of features from a second set of image crops. The technique also includes training the student version of the machine learning model based on one or more losses computed between the first and second sets of features. The technique further includes transmitting the trained student version of the machine learning model to a server, wherein the trained student version can be aggregated by the server with additional trained student versions of the machine learning model to generate a global version of the machine learning model.
