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 tapered conical shaped sleeve which is positioned within the housing and rotatable in both a clockwise and counter-clock wise direction. A pair of grippers are mounted within the connector assembly and engage the surgical saw blade when the tapered conical shaped gripper sleeve is rotated in a first position. A sternum guard is also mounted to the housing.

A connector assembly for connecting a surgical saw blade to a housing of a surgical instrument, the connector assembly comprising:
- a tapered gripper sleeve connected to the housing, the tapered gripper sleeve being adapted to move between a first position and a second position;
- and
- a gripper mechanism positioned with the tapered gripper sleeve, the gripper mechanism having at least one extending projection moveable with respect to the tapered gripper sleeve and adapted to engage a engagement portion on a side edge of the surgical saw blade when the tapered gripper sleeve is in the first position.
A surgical instrument comprising:
- a housing;
- a motor and drive assembly being housed within the housing;
- a tapered sleeve being coupled to the housing and proximate to the motor and drive assembly, the tapered sleeve being adapted to move between a first position and a second position;
- a gripper mechanism positioned with the tapered sleeve, the gripper mechanism having projection means moveable with respect to the tapered sleeve and adapted to engage a side edge of the surgical saw blade when the tapered sleeve is in the first position;
- and
- a sternum guard mounted to an end of the housing and proximate to the surgical saw blade.
A surgical saw blade comprising:
- a blade portion having a plurality of teeth;
- an engagement portion extending from the blade portion to an end of the surgical saw blade, the engagement portion having opposing sloped surfaces extending substantially from the blade portion to the end of the saw blade, the opposing sloped surfaces extending outward from the blade portion to the end with relation to a lateral axis of the surgical saw blade;
- and
- substantially semi-rounded inner surfaces at an interface between the opposing sloped surfaces and the blade portion.
