Surgical tool assembly for total knee arthroplasty
First Claim
Patent Images
1. A surgical tool assembly for Total Knee Arthroplasty (TKA) comprising:
- a femoral intra-medullary (IM) rod, a T-shaped structure formed by a shaft and a rod;
a femoral intra-medullary (IM) alignment guide with a wing section at both sides respectively, a horizontal opening for receiving the IM rod in the middle, two vertical openings on the top;
a distal femoral alignment guide with a platform, a sliding track on the platform, two legs beneath inserted into the two vertical openings; and
a distal femoral cutting guide with a positioning device, a saw slot, fixing holes, and a sliding concave for receiving the sliding track;
the characteristic is the structure of the invention, enabling the distal femoral cutting guide slid to the distal femoral alignment guide in the orientation from distal to proximal to narrow down the size of the incision, thus providing more convenience to the knee replacement surgical procedure and minimizing the femoral quadriceps damage to facilitate patients'"'"' rehabilitation after surgery.

Abstract
A surgical tool assembly for Total Knee Arthroplasty (TKA) including a femoral intra-medullary (IM) rod, a femoral intra-medullary (IM) alignment guide, a distal femoral alignment guide, and a distal femoral cutting guide. After the femoral IM alignment guide is selected to fit the valgus angle and utilized with the femoral IM rod with respect to the distal femur, the distal femoral alignment guide is integrated to the complex. Then, the distal femoral cutting guide is slid to the distal femoral alignment guide in the orientation from distal to proximal through the sliding concave integrated with the sliding track.
