  • Surgical saw blade
    Patent number: 5507763
    Abstract: An oscillating surgical blade formed such that the thickness of the blade adjacent the side edges is reduced relative to the effective thickness of the body of the blade. Therefore, when the side edges of the blade mushroom due to contact with a saw guide slot, the resultant thickness of the mushroomed edges is less than or equal to the effective thickness of the blade body.

  • Surgical saw blade and clamp
    Patent number: 5496316
    Abstract: A blade and clamp obtain a motion free coupling while remaining easily operable. The clamp comprises first and second clamping faces. The second clamping face includes a plurality of tapered lugs arranged in a radial pattern. The blade comprises a plate-like body having a primary U-shaped slot and a plurality of radial U-shaped slots which engage the tapered lugs of the clamp to produce a tight motion free coupling between the blade and clamp.

  • Alternate forms of, side drive drilling
    Patent number: 4875529
    Abstract: Disclosed is a method and apparatus comprising a side drive system with a drive shaft (24, 24a) driven from the platform level (10) and powering a drilling unit (16) for rotating drill pipe (14). Except for the tethering of the drive shaft at the top of the derrick (60-64) and its coupling to a power source (70) at the platform level, there is preferably no stabilizing means for the system. The drive shaft (24, 24a) is stationary, preferably hollow, and extends the height of the derrick located to one side of the main drilling axis. The power source (70) at the platform level comprises a power takeoff from a conventional rotary table (84). The upper drive assembly (18) of the drilling unit (16) is coupled to the drive shaft (24, 24a) and capable of vertical movement along the drive shaft and providing torque to the drill string.
