Single port laparoscopic access system with external tool support

Abstract

A system for performing single port laparoscopic procedures includes a deployment frame and a plurality of tools. The tools are pivotally mounted on the frame and have end effectors which are translatably and rotatably disposed in the tool. A handle at the proximal end of the tool controls an end effector at the distal end of the tool. Movement of the tools relative to the frame is constrained so that they remain in a fixed geometric relationship which prevents the tools from interfering with each other during laparoscopic procedures.

What is claimed is: 
     
         1 . A laparoscopic tool system comprising:
 a frame having a periphery and a central opening in a horizontal plane, said frame being configured to lie over a transcutaneous incision;   a first tool pivotally attached to an exterior of the frame at a first location, wherein a mid-portion of the first tool passes through the central opening of the frame; and   a second tool pivotally attached to an exterior of the frame at a second location, wherein a mid-portion of the second tool passes through the central opening of the frame;   wherein the tools pivot in at least two vertical planes relative to the frame and wherein the mid-portions of the tools are positioned to avoid interference as the tools are pivoted in said at least two vertical planes.
