Drill guide and method for placing a fixation device hole
View Patent ↗The invention relates to a drill guide and method for providing a drill guide, where the drill guide is for placing a fixation device hole proximate to a bone tunnel in a bone. The drill guide includes a foot for placement in the bone tunnel in the bone and a leg extending from the foot and having a recess. A locator is placed within the recess and, in a retracted position, the locator is inside the leg. The locator is also hingedly connected to the leg such that, in an unretracted position, the locator rotates and extends outwardly from the recess for locating a fixation device hole.
1. A method for providing a drill guide for placing a proposed fixation device hole proximate to a bone tunnel in a bone, comprising the steps of:
providing a foot for placement in the bone tunnel in the bone;
extending a leg from the foot;
placing a recess in the leg;
placing a locator entirely within the recess of the leg, thereby defining a retracted position; and
hingedly connecting the locator to the leg such that, in an unretracted position, the locator rotates and extends outwardly from the recess for locating the fixation device hole.
2. The method according to claim 1 further comprising the step of angularly extending the leg from the foot.
3. The method according to claim 1 further comprising the step of controlling the locator for varying a distance between the fixation device hole and the bone tunnel.
4. The method according to claim 1 further comprising the step of pivotably connecting the locator with a shaft and controlling the shaft for varying a distance between the fixation device hole and the bone tunnel.
5. The method according to claim 4 further comprising the step of connecting a threaded knob to the shaft for controlling the locator.
6. The method according to claim 5 further comprising the step of determining a number of revolutions of the knob based on the distance between the fixation device hole and the bone tunnel.
7. The method according to claim 4 further comprising the step of translating the shaft in an axial direction and rotating the locator about the pivotable connection with the leg.
