Abstract
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.
Claims20
A drill guide for placing a fixation device hole proximate to a bone tunnel in a bone, comprising:
- a foot for placement in the bone tunnel in the bone;
- a leg extending from said foot and having a recess;
- a locator placed within said recess and, in a retracted position, said locator is inside said leg;
- and
- said locator hingedly connected to said leg such that, in an unretracted position, said locator rotates and extends outwardly from said recess for locating the fixation device hole.
A drill guide for placing a fixation device hole proximate to a bone tunnel in a bone, comprising:
- a foot for placement in the bone tunnel in the bone;
- a leg extending from said foot and having a recess;
- a locator placed within said recess and, in a retracted position, said locator is inside said leg;
- said locator hingedly connected to said leg in a first location such that, in an unretracted position, said locator rotates and extends outwardly from said recess for locating the fixation device hole;
- said locator is hingedly connected to a shaft in a second location;
- wherein movement of said shaft away from said foot transfers tensile forces to said locator via said second location and causes said locator to rotate about said first location to the unretracted position;
- and
- wherein movement of said shaft toward said foot transfers compressive forces to said locator and causes said locator to rotate about said first location to the retracted position.
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 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.
