[0002] At present, when performing minimally invasive surgery on lumbar fracture patients, precise positioning is required under the guidance of a CT or C-arm machine. Accurate surface positioning can greatly improve the success rate of treatment. Accurate preoperative positioning is very important for spinal surgery. If the positioning is inaccurate, it will inevitably cause the incision to be extended, thereby increasing the injury.

[0003] The utility model with the existing publication number CN211674610U discloses a spinal locator, which includes a vertical positioning member for positioning the spine and a horizontal positioning assembly for positioning joints. The horizontal positioning assembly includes a plurality of horizontal positioning members that can reciprocally slide along the length direction of the vertical positioning member. A limiting boss for limiting the horizontal positioning member is provided on the vertical positioning member. The horizontal positioning member and the vertical positioning member are detachably connected by a locking member. Scale lines are provided on the vertical positioning member. The horizontal positioning member includes a marking positioning member, and a marking member is detachably connected to one end of the marking positioning member.

[0004] In the above technical solution, the inventor found that at least the following problems exist: the length of the horizontal positioning member is fixed and unchangeable. When facing different children or adults later, the length of the horizontal positioning member cannot be adjusted according to the specific usage situation. Therefore, how to design a spinal locator has become a problem that we need to solve currently. Content of the Utility Model
