The spray assembly for a droplet spray teeth cleaning system includes a guidance member at the end thereof. The spray assembly includes a nozzle through which a spray of liquid is directed to the teeth for cleaning. The guidance member is configured and mounted relative to the nozzle to provide a selected standoff distance between the nozzle and the teeth and includes a portion which is configured to fit in the interproximal space between adjacent teeth and gums, or against the frontal portions of the teeth, so that the user knows the location of the spray relative to the teeth.

The spray assembly for a droplet spray teeth cleaning system includes a guidance member (40, 56, 80, 86) at the end thereof. The spray assembly includes a nozzle (24) through which a spray of liquid is directed to the teeth for cleaning. The guidance member is configured and mounted relative to the nozzle to provide a selected standoff distance between the nozzle and the teeth and includes a portion which is configured to fit in the interproximal space between adjacent teeth and gums, or against the frontal portions of the teeth, so that the user knows the location of the spray relative to the teeth.

The technical description relates to mixed reality, augmented reality, and their use in the sharing of information about a procedure and in the performing of a procedure. A method for sharing information about a procedure and performing the procedure includes using a mixed reality system in a first location to display a mixed reality image having a virtual element representing information related to the procedure, instructing an information recipient to use an augmented reality system to view the virtual element, interacting with the virtual element to create a transformed virtual element, and manipulating a physical element in a second location while performing the procedure. Specific examples described herein relate to the field of medicine, and to orthopedics in particular.

The attachment system includes a brushhead assembly having a spring/carrier combination which comprises a spring assembly and a separate carrier assembly, adapted to mate as a combination with a receiving portion, in the form of a cup member, at the top of the handle of the toothbrush. The spring/carrier combination includes a slot which mates snugly with a vertical rib on the inside surface of the cup member, and further includes a portion which opposes the slot on the spring/carrier combination which mates snugly with a cut-out portion in the cup member, to prevent rotational movement of the brushhead relative to the handle. The spring/carrier assembly further includes two opposing spring finger elements which extend downwardly from an upper edge of the spring/carrier assembly and are joined thereto such that the lower ends of the spring fingers have a slightly outward springing action, wherein the lower ends of the spring fingers fit into corresponding openings in opposing sides of the cup member when the spring/carrier assembly is operatively positioned in the cup member, tending to prevent translational movement of the brushhead relative to the handle.

Medical devices, medical device precursors, and methods of making medical devices are described. Examples of a medical devices relate to medical devices, such as those suitable for implantation in spaces between vertebrae in a vertebral column of an animal. An example medical device includes a main body that has a lengthwise axis, a proximal end, a distal end, a length that extends from the proximal end to the distal end, an upper wall, a lower wall, a first lateral wall, a second lateral wall, and defines a plurality of pockets, a plurality of pocket supports, an interior chamber, a plurality of windows, and a recess. A pocket support of the plurality of pocket supports is disposed within each pocket of the plurality of pockets.

The duckbill valve assembly includes at least two duckbill valve members (12,14) and a flexible, flat flange member (16) which joins the two duckbill valve members (12,16) together. The flange (16) connects the duckbill valve members (12,14) together at their respective bases, thereby maintaining the two duckbill valve members (12,14) in a particular orientation and arrangement relative to each other.
