The controller and the terminal device can also be connected through wires or wirelessly. Fig. 4 is a schematic view of a pedicle opener of one embodiment of the present disclosure entering human tissue. As shown in fig. 4, the pedicle opener 1 is currently actually in the cancellous bone 4, and the detected hardness thereof can be identified as being within the range of the hardness of the cancellous bone 4. As the pedicle opener 1 continues to move into the body tissue, it will detect the stiffness of the cortical bone 4, as well as the stiffness of the soft tissue 5.
Fig. 5 is a schematic structural view of a pedicle opener according to another embodiment of the present disclosure. As shown in fig. 5, the pedicle screw includes an opener body 11, a detection part 2, a handle 3, a controller 31, a display assembly 7 and a power module 8.
