A recently granted patent (Publication Number: US11883064B2) discloses a method for accessing an intervertebral disc in a patient through a minimally invasive procedure. The method involves making an incision in the patient's skin, percutaneously inserting an outer shield with a tubular shape to the spine, resecting a portion of the superior articular process, and inserting an inner shield through the outer shield to reach the disc. A video chip is disposed in the outer shield to provide visualization during the procedure. Additionally, the method includes contacting the shield to a nerve root for protection, performing microsurgical decompression, extracting disc material, inserting an interbody device, and stabilizing the intervertebral segment.

Furthermore, the patent claims detail various aspects of the method, such as the configuration of the inner shield, the use of an optical visualization instrument integrated into the outer shield, and the steps involved in stabilizing the intervertebral segment post-procedure. The method also includes the option of coupling a navigation instrument and a light source to the outer shield for enhanced precision during the procedure. Overall, the patented method offers a comprehensive approach to accessing and treating intervertebral discs in patients, combining innovative techniques with minimally invasive principles to improve patient outcomes and recovery post-surgery.
