Abstract
Surgical techniques and instruments are provided for performing surgical procedures in a disc space. The instrument includes a sleeve having a distal end and an opposite proximal end and a working channel extending therebetween. The working channel includes a first portion and an adjacent second portion configured to receive surgical instruments therethrough. A cap member is secured to the sleeve at the proximal end. The cap member has a sealable access port substantially aligned with a corresponding one of the first or second portions. The cap member is movable with respect to the sleeve to substantially align the access port with the other of the first and second portions while the working channel remains sealed. Various techniques using various surgical instruments in laparoscopic procedures are also disclosed.

13. An apparatus for performing surgical procedures in a disc space between adjacent vertebrae of a patient, comprising:
-
a seal; a sleeve having a distal end and a proximal end and a working channel extending therebetween, said sleeve having a perimeter with a non-circular shape, said sleeve further including a flange ring secured to said proximal end having a perimeter with a substantially circular shape, wherein said seal is engaged to said flange ring about said perimeter, wherein said seal comprises; a cap member secured to said flange ring at said proximal end sealing said working channel, said cap member having an access port, said cap member being movable to align said access port with a portion of said sealed working channel and said cap member includes a valve member having a valve disc coupled to at least one actuator for opening and closing said access port, wherein said valve member includes; a stem extending through and mounted to said cap member; said actuator coupled to said stem outside said cap member; and said disc coupled to said stem, wherein said actuator is pivotable from a closed position whereby said disc substantially closes said access port to an open position whereby said disc does not substantially close said access port. - View Dependent Claims (14)
