Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a positioning device used before spinal surgery. Background Art

[0002] Conventional spinal surgery positioning methods include manual iliac crest positioning and Kirschner wire positioning. Among them, the manual iliac crest positioning method is simple and fast, but has low accuracy. The Kirschner wire positioning method is currently the most commonly used method in clinical practice to determine the surgical area. This method requires multiple fluoroscopy and a long positioning time, and the medical staff and patients are exposed to a large amount of radiation. The metal mesh and metal frame positioning method can reduce the number of fluoroscopy times and reduce the amount of radiation received by medical staff and patients, but the metal shape does not conform to the skin surface.
