摘要： A drill sleeve, including: an outer sleeve with an internal collet at a distal end of the outer sleeve, a slot, and an inner opening; a handle connected to the outer sleeve; an inner sleeve with an inner opening configured to receive and guide a drill bit, wherein the inner sleeve is configured to slide inside the inner opening of the outer sleeve; a trigger; a connection member connected to trigger and the inner tube, wherein the connection member passes through the slot in the outer sleeve and a biasing member configured to apply a biasing force between the handle and the trigger wherein the biasing force drives the inner sleeve into the outer sleeve, wherein when a distal end of the inner sleeve engages the internal collet, the internal collet is configured to engage a screw hole in a bone plate, align the drill sleeve with a nominal axis of the screw hole, and secure the drill sleeve to the screw hole.

摘要： A system for inserting an intramedullary nail into a bone includes (a) a handle extending from a proximal end to a distal end configured to couple to an intramedullary nail only in a desired orientation and (b) an aiming device extending from a proximal end to a distal end configured for attachment to the proximal end of the handle. The aiming device includes a guide opening extending therethrough sized and shaped to accommodate a protective sleeve therein. The guide opening is located and oriented so that, when the aiming device and the handle are coupled to one another, a bone fixation receiving hole in an intramedullary nail coupled to the handle is aligned with the guide opening. The aiming device further includes a locking pin fixedly mounted thereto. The locking pin extends into the guide opening to engage a protective sleeve inserted therein.

摘要： The present invention is directed to a dynamic fixation system for engaging, via bone fixation elements, one or more parts of a patient's body. Preferably, the dynamic fixation system is used to engage one or more vertebrae for stabilizing the attached vertebrae with respect to one another while still permitting the vertebrae to move with respect to one another. The dynamic fixation system may include a first rod having first and second ends, a second rod having first and second ends, and a damping component and/or a damping mechanism for interconnecting the first and second rods. In one embodiment, the damping component is injection molded in-between the one of the ends of the first rod and one of the ends of the second rod so that the first and second rods are prevented from separating with respect to one another but are still permitted to move with respect to one another.
