A less invasive access port (100) for use in minimally invasive surgery allows for manipulation of the viewing angle into the working site (340) in a transverse plane. According to one exemplary embodiment, the less invasive access port (100) is designed to minimize the need for muscle retraction. Additionally, the less invasive access portal (100) provides sufficient light, irrigation, suction and space for sundry medical instruments (100, 1220). According to one exemplary embodiment, a less invasive access port device (100) includes a two-piece retractor (120) having locking arms (506) secured by a latch (504). The latch (504) is located outside a wound (320) during operation for ease of access. A cannula (110, 110') includes integrated interfaces (102) for light, irrigation and suction. A housing (108) forms a collar around a top of the cannula (110, 110') and houses the light, irrigation and suction mechanisms. Instruments (100, 1220) and implants may be passed through the cannula (110, 110') and into the working space (130) created by the two- piece retractor (120). Visualization of the working site (340) can be attained under direct vision. |
