Abstract
A surgical tool with a stiffening sleeve that is dynamically retractable during surgery. The tool includes a needle or implement for performing minimally invasive surgery through a pre-placed cannula at a surgical site. A stiffening sleeve of the tool about the implement may provide an added degree of stiffness such as where the implement is particularly thin. However, an end of the sleeve is held in position at the cannula as the implement advances therebeyond for the surgery. Nevertheless, as determined by the surgeon, the implement may be further advanced with a corresponding and deliberate retraction of the sleeve into the tool body as desired.
