APPARATUS AND METHODS FOR BONE REPAIR PREPARATION

摘要

Apparatus and methods for preparing a fractured bone for repair. Preparing the bone may include fracture reduction. Preparing the bone may include holding a fracture in reduction. Preparing the bone may include identifying locations for obtaining access to an interior region of the bone. The apparatus may include structures outside the bone that interact with fragments of the bone. The structures may participate in the reduction. The structures may participate in holding the reduction. The structures may participate in identifying the locations.

1. Apparatus for reducing a fracture of a bone, the apparatus comprising:
a bridging member that defines a first receptacle and a second receptacle, the bridging member spanning from the first receptacle to the second receptacle; a channel within the bridging member; a pressure distribution member that is slidable in the channel between an unlock position and a lock position; and a base rigidly affixed to the bridging member, the base comprising a collar that defines a third receptacle; wherein: the first receptacle is configured to receive a first bone penetrating element at a position, operatively external to the bone, on the first bone penetrating element; the second receptacle is configured to receive a second bone penetrating element at a position, operatively external to the bone, on the second bone penetrating element; the third receptacle is configured to receive a third bone penetrating element at a position, operatively external to the bone, on the third bone penetrating element; when the pressure distribution member is in the unlock position, the bridging member is movable relative to the first and the second bone penetrating elements, and when the pressure distribution member is in the lock position, the bridging member is fixed relative to the first and the second bone penetrating elements; and, when the pressure distribution member is in the lock position, movement of the base along the third bone penetrating element, in operation, bends the third bone penetrating element along a length of the third bone penetrating element that extends between the bone and the base.
