Abstract: A head-mounted device (HMD) for use with a navigation system. The navigation system includes a localizer and a bone tracker coupled to a physical bone. The localizer monitors the bone tracker to track a pose of the physical bone in a localizer coordinate system. Controller(s) obtain surgical plan data related to the physical bone. The surgical plan data includes a virtual model of the physical bone and cut volume data defining material to be removed from the physical bone in preparation for receiving an implant. The controller(s) register the HMD to the localizer coordinate system and provide, on the HMD display, computer-generated imagery representative of the surgical plan data, including the virtual model of the physical bone and the cut volume data. The controller(s) align and combine the computer-generated imagery with a real-world view of the physical bone.

Abstract: Systems and methods for providing access to within a vertebral body. A stylet is removably disposed within a reamer, and the reamer is removably disposed within a working cannula. A tip of the stylet is positioned distal to a reamer head with a stylet hub being positioned proximal to a reamer hub. The reamer hub may include indicia configured to be aligned with the stylet hub to indicate a distance by which the tip is positioned beyond a distal end of the reamer. Complementary coupling features on the reamer hub and the stylet hub are configured to facilitate the workflow and provide mechanical advantage during removal of the stylet from the reamer. The system may include a spacer device configured to be positioned between the reamer hub and the stylet hub. The spacer device may be coupled to a stylet shaft of the stylet.

Abstract: Wireless charging systems and methods for wirelessly charging batteries for powering surgical instruments. A wireless charging device includes a housing defining wireless charging bays for receiving and charging multiple surgical instrument batteries simultaneously.

The RF antennas are each configured to communicate in a same frequency band. The wireless charging device is configured to communicate with a battery received by a first of the wireless charging bays using the RF antenna associated with the first wireless charging bay during a first period while preventing the RF antenna associated with a second of the wireless charging bays from communicating with a battery received by the second wireless charging bay.

Abstract: A patient handling apparatus includes a patient support surface, a base, and a hydraulic circuit. The hydraulic circuit includes a pump, a fluid reservoir, and a hydraulic cylinder operable to selectively raise or lower the patient support surface or the base. The hydraulic circuit controls flow of fluid between the cylinder and the fluid reservoir to thereby control the movement of the base or patient support surface. In addition, the hydraulic circuit may include a manual bypass circuit configured to bypass the pump in response to a manual input, which allows manual extension or retraction of the cylinder, for example, when the pump is not operational. The hydraulic circuit may also include a pump bypass circuit configured to bypass the pump to allow fluid to discharge from the cap end to the fluid reservoir for faster evacuation of fluid from the cylinder, thereby increasing retraction speed of the rod.

Abstract: Inverting tube thrombectomy apparatus for removing clot that are configured to prevent compression of the apparatus that may separate the distal end of the apparatus from the clot and may make it difficult to advance the apparatus to engage with the clot, particularly in a tortious vessel. The apparatuses and methods of using them described herein may be adapted to prevent tension in the flexible tube that is rolling and inverting over the distal end of the inversion support catheter when capturing a clot. Also described herein are inverting tube thrombectomy apparatus that are configured to reload either automatically or manually within the vessel to capture additional clot material.

Abstract: A mill head for replaceable attachment to a base so as to collectively form a bone mill. The mill head includes shell with: a first opening in which bone stock is introduced into the head; and a second opening through which the bone chips are discharged. A cutting device is mounted in the shell to both rotate and move laterally. Attached to the cutting device are coupling features for engaging a drive spindle able to rotate the cutting device. Also attached to the housing is an alignment feature. The alignment feature engages a complementary alignment feature associated with the drive spindle so as a result of the engagement of the alignment features, the cutting device moves within the shell so that the cutting device coupling features are positioned to engage the drive spindle.

Abstract: An ultrasonic tool system with a console and a tip that has a distal end that when vibrated vibrates both longitudinally and torsionally. The console applies a drive signal to the drivers that vibrate the tip that is at a longitudinal mechanical cancelation frequency. Consequently, when the tip is vibrated, at the distal end the longitudinal component of a first resonant mode of the tip cancel out the longitudinal component of the second resonant move of the tip so the distal end of the tip engages in vibrations that substantially torsional and only minimally longitudinal.
