Cross length and angle of knee ligament reconstruction femoral tunnel dimensional measuring instrument

The present invention relates to a cruciate ligament reconstruction femoral tunnel length and an angle-measuring instrument, comprising a U-shaped handle frame, characterized by: further comprising a frame for releasable connection to the handle of the handle frame is fixed to the lower leg fixing assembly on the outer end of the handle frame is provided with a positioning length measuring device movable with tick marks on the measuring device is provided with a solid-cone positioning sleeve on the inner end of the handle frame, the positioning the distal end of said tapered sleeve is provided with a gauge length of the hollow sheath is positioned on the heart and is connected with a horizontal plane perpendicular to the large end of the tapered sleeve positioned, rotatably angle measurement substrate, the angle measurement defines an arcuate channel substrate, vertically disposed within said channel plate has a surface having an angle measuring scale line. The present invention is of simple structure, practical, easy to operate, noninvasive, effective, accurate and fast measurement of the pre-drilled femoral tunnel length and angle, to facilitate subsequent medical operations.
