Tissue retraction system

A tissue retraction system comprising:

• a surgical retractor including:
• a body having a post defining a single point of attachment and a vertical axis, the post including a tapered cut;
• a right arm assembly coupled to the body and configured to adjustably move along a first trajectory;
• a first retractor blade configured to be coupled to the right arm assembly;
• a left arm assembly coupled to the body and configured to adjustably move along a second trajectory;
• and
• a second retractor blade configured to be coupled to the left arm assembly;
• and
• an articulating arm including:
• an aperture for connecting to the post, the post defining a single point of attachment of the articulating arm to the surgical retractor;
• a push button having a mating tapered surface that interfaces with the tapered cut of the post to rigidly connect to the post at a selective circumferential angle relative to the vertical axis,
• wherein the button is spring loaded, and the spring loaded button, the aperture, the tapered cut and the mating tapered surface define a quick-connect mechanism to allow the articulating arm to rigidly engage the post from insertion of the post into the aperture without pressing of the button and without any other motion
• wherein the surgical retractor includes:
• a drive gear coupled to a shaft, wherein the drive gear is configured to rotate along a first axis based on movement of the shaft;
• a first plurality of linking members located along a second axis and configured to rotate along the second axis based on contact with the drive gear as the drive gear is rotated;
• a selector configured to rotate along the first axis;
• wherein the right arm assembly is configured to move along a first trajectory based on a corresponding movement of at least two linking members of the first plurality of linking members.
