This invention relates to the field of orthopedic surgical instruments and discloses a femoral side drilling locator for cruciate ligament double-bundle reconstruction. The locator includes a handheld component with a mounting plate at its end. The mounting plate is equipped with a replaceable positioning component, a limiting component for fixing the positioning component, a fixing component that cooperates with the limiting component, and a locking component for pressing the positioning component. This invention, through the anchoring of the positioning rod with the pre-drilled bone hole and the rigid guidance of the positioning hole, can precisely control the parallelism and interlocking relationship of the two bone holes, avoiding slippage and displacement during drilling. It solves the problems of lack of stable constraint and deviation in the position of the two holes in existing operations. Furthermore, the replaceable positioning component and spring-linked locking design provide support for the preparation of bone holes of different sizes, adapting to different patient anatomical dimensions and graft specifications. It also enables rapid disassembly and immediate fixation of the positioning component, effectively improving the accuracy, convenience, and adaptability of cruciate ligament double-bundle reconstruction surgery.
