Percutaneous discectomy system having a bendable discectomy probe and a steerable cannula

摘要

A percutaneous dissectomy system (20) having a bendable dissectomy probe (22) and steerable cannula (24) allows for a wide range of positions relative to the dissectomy tissue to be severed. The bendable dissectomy probe (22) includes a bendable section (78, 86) which can allow the probe (22) to be bent more than 90 DEG 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.
