    摘要: 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.

    摘要: A spinal rod connector is adapted to connect two spinal rods. The spinal rod connector includes first and second channels which are defined in a housing. The first and second channels can be urged together in order to capture first and second spinal rods when a fastener is actuated. The spinal rod connector allows the first and second rods to be positioned relative to each other in one of a parallel and a non-parallel manner prior to the fastener locking the first and second spinal rods in position.
