Positioning bracket for multiple bone tunnel drill guides

A positioning bracket comprising:

• a frame;
• a first slide block attached to the frame, the first slide block being capable of motion in a lateral direction across the frame, the first slide block including a first locking mechanism that is engagable with the frame to secure the first slide block at a first securement location;
• a second slide block attached to the frame, the second slide block being capable of motion in the lateral direction across the frame, the second slide block including a second locking mechanism that is engagable with the frame to secure the second slide block at a second securement location;
• a first adapter block attachable to the frame via the first slide block, the first adapter block being configured to secure a first bone tunnel drill guide, the first adapter block being rotatable about a first axis that passes through the first slide block when the positioning bracket is fully assembled;
• a third locking mechanism configured to lock the first adapter block at a first angle of rotation with respect to the first slide block;
• a second adapter block attachable to the frame via the second slide block, the second adapter block being configured to secure a second bone tunnel drill guide, the second adapter block being rotatable about a second axis that passes through the second slide block when the positioning bracket is fully assembled;
• and
• a fourth locking mechanism configured to lock the second adapter block at a second angle of rotation with respect to the second slide block.
