摘要： A less invasive access port for use in minimally invasive surgery allows for manipulation of the viewing angle into the working site in a transverse plane. According to one exemplary embodiment, the less invasive access port is designed to minimize the need for muscle retraction. Additionally, the less invasive access portal provides sufficient light, irrigation, suction and space for sundry medical instruments. According to one exemplary embodiment, a less invasive access port device includes a retractor assembly having four retractor blades secured in various positions by pins placed within slots on the retractor blades. A cannula includes integrated interfaces for light, irrigation and suction. A housing forms a collar around a top of the cannula and houses the light, irrigation and suction mechanisms. Instruments and implants may be passed through the cannula and into the working space created by the retractor assembly. Visualization of the working site can be attained under direct vision.

摘要： A pedicle screw and rod assembly is provided which has a low profile in the final position. The pedicle screw includes a screw having a threaded portion and a head portion. A tulip body is positioned on the head portion of the screw. A tulip saddle is coupled to the tulip body and positioned to retain the tulip assembly on the pedicle screw. Wedge members are inserted in between the tulip body and the tulip saddle, causing the saddle to compress and thereby retain a rod within the tulip assembly. Colored wedge members alert a surgeon as to whether the system is in a locked or unlocked state. The top of the tulip assembly is approximately equal in height to, or lower than the rod itself. This provides a low profile pedicle screw and rod assembly since the rod itself will be the uppermost member of the completed assembly.
