Abstract: A surgical instrument having a locking throttle mechanism. The throttle is pivotally mounted to a wand-type housing by a hinge, and the housing includes a tool tip and a connecting mechanism. The throttle fits in an indented portion of the housing when it is in an ON position. An actuating switch is placed under the throttle and is controlled by a sliding grip/safety switch located on the throttle. A slidable locking mechanism is placed within a cavity of the throttle and may be moved between a locked position and an unlocked position. In the locked position, a portion of the slidable locking mechanism communicates with a locking cavity proximate to the lip of the housing. A spring is located between the throttle and the housing and urges the throttle into an OFF position and is compressed when the throttle is advanced downward towards the housing.

Abstract: A pulsed lavage attachment (40) is secured to a conventional, powered, modular, surgical hand piece (42) to allow a pulsed lavage delivery set (18) to be connected to and controlled by the hand piece (42), thereby eliminating the need for dedicated air or power lines and a dedicated pulsed lavage hand piece in the operating room. The pulsed lavage attachment (40) includes an internal driver (52) which mates with an output driver of the hand piece (42) and is axially rotatable by the output driver. A cam driver (56) connected to the internal driver (52) by pegs or other suitable means, and is rotatable therewith, has a cammed surface (62). A bearing member (64) rides on the cammed surface (62), and drives shaft (66) in an axial direction. Membrane (68) flexes outward to actuate a connecter (24) of the pulsed lavage delivery set (18) to actuate an internal pumping cartridge therein.

Abstract: A surgical saw blade for removable mounting in clamps having rectangular lugs and in clamps having circular pins, by way of closed slots having semi-circular distal ends, and arranged to have the respective centers of the semi-circular ends about a pattern radius. Each slot has a side face forming an included angle with a radial line from the hub center to the center of the slot semi-circular end. The included angle is alternating in rotational direction or, with a common offset about the pattern radius of the semi-circular ends, is in an identical direction for each slot.

Abstract: A non-constrained total joint prosthetic replacement device for metatarso-phalangeal joint. A first component comprises a convex-bearing surface and a rearwardly projecting stem configured to be received in the resected metatarsal bony shaft, and a second component includes a concave-bearing surface and a stem configured to be received within the resected phalangeal bony shaft. A non-bearing intermediate land offsets the convex-bearing surface of the first component from the stem, allowing a full range of anatomical motion notwithstanding the presence of bony overgrowth.
