Abstract
An impacting device for inserting, positioning and/or removing an implant and/or performing other impacting applications. The impacting device may have a head having at least one recess. The recess may have a insertion channel and a locking chamber. In one embodiment, the insertion channel and the locking chamber may be connected by an axial channel. The recess may pass through a lateral surface of the head so that the base surface may remain cohesive or unobstructed. A guide means, such as a guide rod, may be positioned though the recess so that the head may be moveable on the guide means and not disengage the guide means. A shaft having a handle may be attached to the head to assist a surgeon in moving the head on the guide means.
Claims21
1-18. (canceled)
A method for inserting or removing a device from tissue, comprising:
- inserting a guide device into a first channel of a recess of a substantially cylindrical head of an impacting device in a direction perpendicular to a longitudinal axis of the head, the head having a lateral surface and at least one base surface, the recess positioned in the head and further having a second channel, the first and second channels being separated a distance from each other and connected to each other via a third channel, wherein the first and second channels intersect the lateral surface but not the base surface and the third channel extends parallel to the longitudinal axis, the first channel including a first end exposed to an exterior of the head and a second end connected to a first end of the third channel and the second channel including a first end connected to a second end of the third channel and a second end covered by the head;
- moving the guide device through the third channel along the longitudinal axis;
- inserting the guide device into the second channel;
- and
- rotating the guide device within the second channel so that the head is moveable along the guide device.
A method for inserting or removing a device from tissue, comprising:
- inserting a guide device into a first channel of a recess of an impacting head of an impacting device, the impacting device comprising an elongated shaft extending along a first longitudinal axis, the impacting head configured to be removably attached to the shaft and extending along a second longitudinal axis angled relative to the first longitudinal axis and having a lateral surface and a base surface formed to impact a bone implant when said impacting device is attached to the shaft, the recess being positioned in the head and including a second channel connected to the first channel and angled with respect to the first channel in a first plane parallel to the second longitudinal axis and wherein the first and second channels do not intersect the base surface;
- rotating the guide device to move the guide device from the first channel into the second channel;
- and
- rotating the head about the second longitudinal axis as the head is moved along the guide device.
The method of claim 29, wherein the guide device is a guide rod.
