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 implantable fixation system for fusing a joint between a first bone and a second bone. The system may include an anchor, standoff, bolt, and cortical washer. The system may be implanted across the joint along a single trajectory, the length of the system adjustable to provide compressive force between the anchor and the cortical washer. The system may be implanted across a tibiotalar joint with the anchor positioned in the sinus tarsi. A spacing member may be inserted between the two bones and the fixation system implanted to extend through an opening in the spacing member. The spacing member may be anatomically shaped and/or provide deformity correction. An ankle arthroplasty system may include a tibial plate, a talar plate, and a bearing insert. The plates may be anchored to the tibia and talus along a single trajectory. The ankle arthroplasty system may be revisable to a fusion system.

Abstract: A laryngoscope with automatic image adjustment is revealed. The laryngoscope includes a laryngoscope body, a rotation assembly, a display and a sensor. The laryngoscope body is disposed with a fixing slot and is used for capturing an image. One end of the rotation assembly is fixed in the fixing slot while the other end thereof is arranged with the display. The display is rotated around the rotation assembly. The rotation assembly is set with a limiting slot. The sensor is electrically connected to a rear side of the display and is located inside the limiting slot. While the display being rotated, the sensor is slid on the surface of the rotation assembly. When the sensor is slid in the limiting slot, the display shows the image. Once the sensor is slid outside the limiting slot, the display shows a reflection of the image. Thus the image is adjusted automatically.
