Abstract
An orthopaedic surgical instrument may include an elongated body with a proximal end and distal end. A clamp lever may be pivotally coupled to the proximal end of the elongated body. The clamp lever may be moveable between a locked position and an unlocked position. A biasing element may be configured to bias the clamp lever to the locked position.
Claims9
A method for surgically preparing a distal end of a femur at a knee joint to receive an orthopedic prosthesis, the method comprising:
- attaching a depth stop to an elongated body at a first position of a plurality of positions along the elongated body, securing a broach to a proximal end of the elongated body, the broach having a tapered outer surface with a plurality of cutting teeth defined in the outer surface, advancing the broach along an anatomical axis of the femur through a distal opening of a medullary canal at the distal end of the femur at the knee joint, and engaging a proximal surface of the depth stop with a distal surface of the femur.
A method for surgically preparing a distal end of a femur to receive an orthopedic prosthesis, the method comprising:
- attaching a depth stop to an elongated body at a first position of a plurality of positions along the elongated body, securing a broach to a proximal end of the elongated body, the broach having a tapered outer surface with a plurality of cutting teeth defined in the outer surface, advancing the broach along an anatomical axis of the femur through a distal opening of a medullary canal of the femur, engaging a proximal surface of the depth stop with a distal surface of the femur, engaging a non-captured cutting guide of the proximal surface of the depth stop to resect the distal end of the femur, advancing the broach along an anatomical axis of the femur after resecting the distal end, and engaging the proximal surface of the depth stop with the distal surface of the femur after resecting the distal end.

- operating a clamp lever pivotally coupled to the elongated body to engage a catch of the clamp lever with the broach, the clamp lever including a distally extending arm having its distal end positioned in a cavity defined in the elongated body and a proximally extending arm extending out of an open proximal end of the cavity, the proximally extending arm having the catch formed in its proximal end.
