Surgical sagittal saw and method of using same

A surgical sagittal saw including a handpiece from which a planar guide bar extends. A saw blade is mounted to the distal end of the guide bar to move across the guide bar. Drive rods connect the saw blade to a drive assembly in the handpiece, which drive assembly reciprocates the drive rods. The drive rods oscillate the saw blade across the distal end of the guide bar. The saw is used with a cutting guide that is in a fixed position relative to the bone or hard tissue to be cut. A capture element is disposed adjacent the guide surface and holds the guide bar to the guide surface so the cut is made along the desired cut plane.

Hole-saw assembly including two hole-saws

The present invention relates to an improved hole-saw assembly and in particular, to a mandrel engageable by a drill and including at least one locking ring or annulus that allows for the base of two hole-saws of different diameter to be quickly and easily mountable and demountable from the mandrel. The hole-saw assembly includes a first hole-saw having a base that includes a pair of drive-pins extending outwardly therefrom and a pair of apertures for insertion therethrough of the drive pins of a second hole-saw. The drive pin pairs are then inserted through corresponding apertures in the mandrel to engage an annulus coupled to the mandrel. The present invention provides for each drive pin to be engaged by the annulus despite the difference in longitudinal length of the drive pins beyond the base of the first hole-saw. The hole-saws are snap-fit within the annulus and may be disengaged by simply rotating the annulus to a second position. A further embodiment of the present invention further allows one to insert the hole-saws into any one of the mandrel insertion points without being concerned about whether it contains the correct engaging means or not. A still further embodiment of the invention prevents slight longitudinal movement which is known to occur when the hole-saws are coupled to the mandrel.

Folding saw

InactiveUS6463663B1Protective coverOvercome these defectsMetal sawing devicesPad sawsEngineeringMechanical engineering
A folding saw in which either the edge of the blade, the handle or both are curved, to prevent the edge of the blade from being exposed when blade is folded so that the saw can be handled safely. The protective cover in which the edge of the blade can be nestled is placed inside the housing groove of the handle having a semi-U-shaped cross section for housing the blade. The protective cover is retractable with respect to the housing groove, and when the blade is folded, projects out of the housing groove and covers the edge, which may be exposed. The protective cover is preferably energized by a spring so that it covers the edge whenever the blade is folded.
