First Claim
Patent Images
1. A connector assembly comprising:
- an upper clamping plate movable between a first locked position and a second unlocked position;
a cam plug;
a lower clamping plate positioned between the upper clamping plate and the cam plug;
a clamping rod attached to the upper clamping plate and extending through a bore of the lower clamping plate and the cam plug; and
a cam lever having a cam surface, the cam lever being pivotally attached to the clamping rod at an end remote from the upper clamping plate, the cam lever being pivotable between a first position and a second position, wherein when the cam lever is pivoted to the first position the cam surface contacts the cam plug and the cam lever moves the clamping rod which positions the upper clamping plate into the first locked position proximate, and releases the upper clamping plate to the second unlocked position remote from the lower clamping plate when pivoted to the second position.

Abstract
A connector assembly for connecting a surgical saw blade to a housing of a surgical instrument. The connector assembly allows a surgeon to align, insert and lock the surgical blade in the collet of the surgical instrument without any special tools, and further provides a stable and robust platform for mounting the surgical saw blade thereto. The connector assembly includes a cam lever assembly for allowing the user to apply a clamping force to the surgical saw blade with minimum actuation force.
