Femoral tunnel length and angle three-dimensional measurement instrument for knee joint cruciate ligament reconstruction

The utility model relates to a femoral tunnel length and angle three-dimensional measurement instrument for knee joint cruciate ligament reconstruction. The femoral tunnel length and angle three-dimensional measurement instrument is characterized in that the femoral tunnel length and angle three-dimensional measurement instrument comprises a U-shaped handle rack, a movable positioning length measurer is arranged at the outer side end of the handle rack, scale lines are arranged on the measurer, a positioning sleeve is fixedly arranged on the inner side end of the handle rack, a long hollow positioning sheath aligned with the measurer is arranged at the front end of the positioning sleeve, the positioning sleeve is conical, an angle measurement substrate which is perpendicular to the horizontal plane and capable of freely rotating is connected to the big end of the positioning sleeve, the angle measurement substrate is a symmetrical half body and is hinged through a connecting rod bearing, an arc-shaped groove channel is formed in the angle measurement substrate, and a measuring plate with angle scale lines on one surface is arranged in the groove channel perpendicularly. The femoral tunnel length and angle three-dimensional measurement instrument is simple and practical in structure, convenient and fast to operate, capable of being used for measuring the length and the angle of a pre-drilled femoral tunnel noninvasively, effectively, accurately and fast, and favorable for subsequent medial work.
