Abstract
The present disclosure relates to a saw, comprising a drive, a first blade configured to oscillate about an axis perpendicular to a plane defined by a surface of the first blade, a second blade configured to oscillate about an axis perpendicular to the plane in a direction opposite to that of the first blade, and wherein gearing is provided between the drive and the first and second blades to reduce the speed transmitted from the drive to the blades. A saw blade, a connection mechanism for connecting a blade to a saw and associated methods are also provided.
Claims19
A surgical saw blade configured to cut bone comprising:
- a cutting edge at a distal end, wherein the cutting edge is elongate along a first axis;
- an attachment portion at a proximal end of the blade, the attachment portion configured to connect the blade to a saw;
- and
- a projection extending from a blade body of the blade and resiliently biased into a position in which the projection extends away from a surface defined by the blade body of the blade, wherein the projection is offset from the cutting edge, and the projection is pivotable relative to each of the blade body and the cutting edge about a pivot axis that is parallel to the first axis.
