MINIMALLY INVASIVE DISCECTOMY |
摘要 |
Systems and methods for minimally invasive discectomy procedures are described herein. The systems include a bendable flexible cannula may have a straight configuration suitable for insertion and withdrawal into spinal tissue, and a curved configuration suitable for accessing certain areas of a vertebral disc that may be difficult to reach in the straight configuration. A cannula is straightened by inserting a straight stylet therethrough. The straight stylet may have a deflectable region that facilitates its insertion into the cannula. Removal of a straight stylet from a cannula may allow the cannula to assume its curved configuration. The systems may be used with tissue removal devices, and certain variations of tissue removal devices may comprise a collector for aspiration, as well as a travel limiter to restrict inadvertent motions of the tissue removal devices within a vertebral structure. |
