Abstract
A percutaneous discectomy system 20 having a bendable discectomy probe 22 and steerable cannula 24 allows for a wide range of positions relative to the discectomy tissue to be severed. The bendable discectomy probe 22 includes a bendable section 78, 86 which can allow the probe 22 to be bent more than 90.degree. and still maintain the function required in order to sever and remove tissue. The steerable cannula 24 has a similar bendable section 102 which can appropriately position the end 50 of the discectomy probe 22 in order to address tissue to be removed.
