  • Publication number: 20130012945
    Abstract: There is provided a drill guide assembly (10) adapted for removable connection to a bone plate (200, 310, 1150, 1250) and for guiding a drill bit (300) through at least one hole (202, 312) that has a central axis. The drill guide assembly (10) includes a guide sleeve (80, 600, 910, 952, 1000, 1052, 1110, 1210) and a guide collar (30) connected to the guide sleeve. The guide collar has an outrigger (40, 500, 800), and the outrigger has at least one opening (42, 504, 804) adapted to receive the drill bit. The at least one opening allows an operator to select an angle for placement of the drill bit and limits the maximum angle selectable by the operator.

  • Publication number: 20120136396
    Abstract: Systems for reducing a fracture in a bone, comprising a bone plate and a polyaxial fastener. In some examples the head of the polyaxial fastener has a deformable portion. As a fastener is inserted into an opening of a bone plate, threads located within the opening deform the deformable portion to secure the fastener in place at a desired angle within the opening. The head of the fastener also includes a bottom portion that bears against a portion of the opening to move the bone plate relative to the underlying tissue. A securing member or other structure may be included at the interface of the head and the deformable portion to secure the deformable portion to the head. At least one flute may be included on the deformable portion that provides a lead-in for the threads within the opening to cut into the deformable portion.

  • Publication number: 20090202363
    Abstract: A portable air compressor assembly includes a tubular frame having side sections and an assembly longitudinal axis. A support plate between the side sections supports a power unit having a longitudinal axis arranged perpendicular to the assembly longitudinal axis. A compressor having a compressor head and longitudinal axis is mounted to the support plate with the compressor longitudinal axis parallel to the power unit longitudinal axis and perpendicular to the assembly longitudinal axis. A fan connected to the power unit generates an air flow. A ducted cover enclosing the fan includes an air passage directing the air flow from the fan to the compressor head. The ducted cover includes inner and outer covers each including a portion of the air passage. An air scoop extends into the outer cover portion of the air passage to redirect the air flow.
