Abstract
A smart surgical instrument for artificial joint replacement includes a femur resection device, a tibia resection device, and a detector having a shape corresponding to the resected surfaces of a femur and a tibia. The femur resection device includes a laser device such that the femur resection device can be aligned for resection of the femur without drilling an intramedullary hole, thereby preventing complications attributable to the intramedullary hole. The tibia resection device includes a laser device, thereby enabling an easy and fast surgical operation without using an extramedullary aligner used for alignment of a tibia during resection of the tibia. The detector includes a rotation detection means and a pressure detection means and is inserted between trials to allow numerical verification for medial and lateral balance of forces and a rotation state of the trials. The surgical instrument enables a precise, accurate, easy, and fast surgical operation.
