Device for connecting surgical clearing or drilling tool components

A device for the coaxial connection of a surgical rotating tool to a shaft comprising:

• a substantially circular cylindrical member having a first end including a wall, the wall having an outer and inner surface, the inner surface defining a substantially circular cylindrical chamber having a central axis, the cylindrical member further having a second end for coupling to the tool;
• a shaft having a front end, the front end slidably engageable with the chamber;
• and
• wherein the outer surface of the wall has at least one impression corresponding to at least one projection on the inner surface in communication with the chamber such that the at least one projection engages the front end of the shaft to form a rotatively and axially locking connection between the shaft and the cylindrical member.

A method of forming a fixed connection of a surgical rotating tool to a shaft, the method comprising the steps of:

• providing a shaft having a substantially circular cylindrical front end having a first diameter;
• providing a substantially circular cylindrical member having a first end including a wall, the wall having an outer and inner surface, the inner surface defining a substantially circular cylindrical chamber having a central axis and a second diameter, the cylindrical member further having a second end for coupling to the tool;
• inserting the front end of the shaft into the chamber, the diameters being dimensioned such that a sliding fit is formed between the shaft and the chamber;
• deforming the outer surface of the wall and forming at least one projection on the inner surface of the wall, the projection engaging the front end of the shaft thereby deforming the front end of the shaft to produce a rotatively and axially locking connection between the shaft and the cylindrical member.
