ABSTRACT:
A coupling device is used for attaching a dissecting tool to a rotary shaft of a surgical instrument. The device is comprised of a spindle attachment which secures to a spindle of the rotary shaft. The spindle attachment has a shaft engagement portion for engaging the shaft of the dissecting tool. The shaft engagement portion is provided with apertures which terminate within a central bore of the engagement portion through which the tool shaft extends. Surrounding the spindle attachment is a sleeve which has a contact surface which contacts spherical locking members located within the apertures of the shaft engagement portion. A sleeve engagement member is coupled to the base and has an external surface configured to allow a user to grasp the sleeve so that it can be moved between retracted and extended positions. As the sleeve engagement member is moved between the retracted and extended positions, it causes the sleeve to be move to an engaged or disengaged position. When moved to the engaged position, the contact surface of the sleeve forces the locking members into the central bore where the locking members contact the shaft of the dissecting tool, preventing movement of the dissecting tool within the socket of the spindle. The sleeve can then be moved to a disengaged position wherein the spherical locking members are allowed to retract within the apertures, allowing the dissecting tool to be removed from the socket.
