NONINVASIVE LOCKING OF DISTAL HOLES IN CANNULATED INTRAMEDULLARY NAILS IN SURGERY

摘要

A system and a method for facilitating a locking of distal holes in a cannulated intramedullary nail are disclosed. The system includes a transmitter, an internal guide, an extension, and schematic renderings of the distal holes and the extension. The transmitter is capable of representing an origin of a local coordinate system. The internal guide includes a first sensor and is capable of guiding the first sensor along the canal of the cannulated intramedullary nail to the distal holes. The first sensor is capable of transmitting a position and rotation of the internal guide relative to the origin. The extension includes a second sensor and is adapted to allow use of drilling and screwing tools. The second sensor is capable of transmitting a position and rotation of the extension relative to the origin. The schematic renderings of the distal holes and the extension facilitate their alignment along a common axis.
