THREADED BONE FILLING MATERIAL PLUNGER

摘要

Described herein are devices, systems and method for assuring that connection regions (e.g., threaded regions) of stabilization devices are clear of bone filling materials such as bone cements. A stabilization device may be referred to as a bone stabilization device or an anchor, and may be a self-expanding device configured for insertion into bone. One exemplary clearing device is configured as a plunger-type device for clearing the connector region by scraping and/or rubbing the surface of the connector region. A clearing device may include a handle, a rod and a connector end that is configured to mate with the connector of a stabilization device. The connector end may include one or more scraping surfaces (e.g., edges) and may include a vacuum port for removing material such as scraped bone cement.

主权项

1. A clearing device for clearing the proximal connector region of a self-expanding bone stabilization device, the clearing device comprising:
a proximal handle; an elongated shaft coupled to the proximal handle; and a distal cleaning region on the elongated shaft having an inclined surface configurable to scrape a proximal connector region of a bone stabilization device to remove a bone filler from the proximal connector region.
