Abstract: An Adaptive Dust Shield Device having Zero Standoff Capability for rotary grinders having a bearing housing and an axial groove around the bearing housing. The dust shield has a cover molded from a single shot. The cover has a plurality of upstanding flexible fingers, in multiples of four, which extend upward from the cover. A door is formed in one side of the dust shield cover to allow the user to use the dust shield in zero clearance situations. The flexible fingers have a defined width and are separated apart from each other by a space between each one. The width of the space is less than the defined width of the flexible fingers. A stretchable fitting ring fits onto the bearing housing of the grinder and under the flexible fingers. The flexible fingers are secured onto the stretchable fitting ring by a securing fastener. There are a plurality of vent holes formed in the top wall that are selectively pluggable with plug elements.

Abstract: A safety-stop device for use with a trochar which is adjustably attachable to the trochar tube to prevent inadvertent cuts being made to a patient. The safety-stop device has retention component for retaining it onto the trochar tube; a registration component for registering a pre-determined insertion point of the trochar; a stop component for preventing additional insertion of the trochar after the pre-determined insertion point has been attained; and a plurality wings with apertures on the base for securely suturing the safety-stop device to a patient by suturing through the apertures and into the patient. The base and wings are made of any thermoplastic material.

Abstract: For a power saw, a dust-capturing device having a hollow capture member with openings on each end wherein one end captures dust and the other end discharges the dust into an attached external vacuum device; a support member securable to, and translatable on, the capture member; and a mounting member pivotably attached to the support member at one end and adapted to adjustably secure the capture member to the power saw at the other end.

Abstract: For a power cut-off saw, a debris-collection device pivotably mountable to the cut-off saw. The device has a collection chamber with a top slot and a front slot in communication with the top slot. Both slots are adapted to receive the cut-off saw blade; the front slot is adapted to capture dust from the cut. A debris-control component may, but need not, cover the top slot and permits entry of the saw blade but prevents dust from escaping. A discharge arm on the top of the collection chamber has a hollow channel which communicates with the collection chamber and facilitates the discharge of dust from the collection chamber by an externally connected vacuum source which suctions out the collected dust.

Abstract: For a power saw, a dust-capturing device composed of two sides shields with one side shield having an exhaust duct adapted to be attached to a hose of an external vacuum and a rear panel to aid in capturing and containing dust generated by the saw's use; and the other side shield having a top and rear beveled portion disposed toward the saw to aid in capturing and containing dust generated by the saw's use. The side shields may be of a one-piece or two-piece construction and are adapted to be securely attached to a saw at or near the upper blade guard of the saw. Capturing dust with only one side shield is effective; but, use of both side shields increases the effectiveness. The attachment mechanism to attach the device to the saw may be stationary or adjustable to accommodate any adjustments necessary for varying depths of cuts.

Abstract: A orthopaedic device for aligning the patella includes a patellar pad which is affixed to the leg of a patient over the patella. A sleeve having an aperture is placed on the leg to project the patellar pad through the aperture. The sleeve includes a gripper located a distance from the aperture. The device also includes an aligner. The aligner has an attachment that is connectable with the patellar pad through the aperture. Additionally, the aligner has at least one elastic strap connectable under tension to the gripper. By selectively attaching the elastic strap or straps between the patellar pad and the gripper, a force is generated of the proper magnitude and direction to align the patella. In alternative embodiment, the sleeve includes an activator positioned between the sleeve and the patient's vastus medialis oblique muscle. Contact between the activator and the vastus medialis oblique muscle allows the patient to isolate and selectively train that muscle and provides a stimulating therapeutic effect.

Abstract: A shield attachment for fitting on a rotating grinder that encloses and shields the rotating grinder disc or pad, and provides a tangential exhaust port for exhausting dust in moving air created by the rotating disc. The shield has an encircling skirt that rests on the work surface, making an enclosed air cavity around the rotating disc that shields against particles being radiated at high speeds and also contains the air with contaminating dust in its restricted passage to the exhaust. The shield has flexible means for allowing vertical movement of the skirt to assure an enclosed chamber, and has separate air holes for providing air flow to the chamber to replace the air passing through the exhaust port.
