Abstract

The disclosure provides a tissue removal device including customizable tips. The tissue removal device may include an outer shaft and a threaded shaft. One aspect of disclosure may include a shaft cutting tool that emerges from the end of the outer shaft. Another aspect of the disclosure may include a flexible cutting blade extending from the threaded shaft.
