Abstract

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.
