[0002] The spinal puncture locator is used for puncture positioning of a target point deep in the spine. Specifically, it can be used for puncture positioning of various parts of the spine such as the intervertebral foramen, intervertebral disc, articular process and pedicle. During spinal puncture. If the target is located deep in the spine or the surgical area is extremely small, and there are many important nerves, blood vessels and internal organs surrounding it, it is sometimes necessary to avoid the obstruction of hard bone tissue. Before the operation, the path of the needle needs to be strictly calculated to avoid repeated fluoroscopic positioning and adjustment of the direction, angle and depth of the puncture needle. Repeated punctures and multiple fluoroscopy not only prolong the operation time, but also increase the patient's pain and X-ray radiation, and increase the risk of surgery and the possibility of infection. Even repeated puncture positioning may not necessarily obtain the ideal target position, which significantly reduces the efficacy of the operation.
