[0023] The sawing assembly 1 includes a first reflective matrix 11 and a saw 12. The first reflective matrix 11 is installed on the saw 12, and the saw 12 is installed on a robotic arm (six-axis articulated type).

[0024] The leg bone calibration assembly 3 includes a second reflective matrix 31 and a mounting bracket 32. The second reflective matrix 31 is installed on the mounting bracket 32. The saw 12, the binocular camera 2, and the leg bone calibration assembly 3 are spaced apart. The robotic arm drives the saw 12 to move, and the binocular camera 2 can capture the first reflective matrix 11 and the second reflective matrix 31.

[0025] During the process of hip and knee surgery, the doctor needs to determine the relative position of the saw 12 with respect to the hip and knee joints. For this purpose, it is necessary to use the first reflective matrix 11 and the second reflective matrix 31 to obtain the surgical positions of the patient's hip and knee joints. During the surgery, the first reflective matrix 11 and the second reflective matrix 31 can be photographed and recognized by the binocular camera 2 or the infrared optical navigation locator, so as to obtain the relative positions of the first reflective matrix 11 and the second reflective matrix 31 and the surgical positions of the hip and knee joints. Since the positions of the first reflective matrix 11 and the saw 12 are fixed, determining the position of the first reflective matrix 11 can determine the position of the saw 12 on the robotic arm, which is convenient for the doctor to know its position and facilitates the doctor to perform the surgery, saving a lot of time in the actual use process and making it more convenient for the doctor to perform the surgical operation.

[0026] In a preferred embodiment, the first reflective matrix 11 includes a first array substrate 111 and a plurality of reflective balls 112. The plurality of reflective balls 112 are detachably mounted on the first array substrate 111 at intervals.

The plurality of mounting sleeves 113 are detachably mounted on the first array substrate 111 at intervals, and the plurality of reflective balls 112 are respectively mounted on the plurality of mounting sleeves 113. It should be noted that in this embodiment, the number of the plurality of reflective balls 112 is four, and the number of the plurality of mounting sleeves 113 is four. In this way, when the plurality of reflective balls 112 are mounted on the first array substrate 111, it is also convenient to detach and replace the damaged reflective balls 112.

[0028] In a preferred embodiment, the leg bone calibration assembly 3 further includes a third reflective matrix, which is mounted on the mounting frame 32 and is spaced apart from the second reflective matrix 31. It should be noted that in this embodiment, the structures and shapes of the second reflective matrix 31 and the third reflective matrix are the same as those of the first reflective matrix 11. Since the third reflective matrix is used as a backup, it will not be described in detail here.
