Abstract

Systems, devices and methods related to retractor systems that retract tissue to allow access to a surgical site are described. The retractor systems can include a first rotatable arm attachable to a first blade, a second rotatable arm attachable to a second blade and a third linearly translatable arm attachable to a third blade. An attachment mechanism that is attachable to a fourth blade can be removably coupled to a mount on the frame. The retractors systems can also include two blade systems whereby when the retractor is in a closed configuration, the two blades form an oval opening.

A multi-blade retractor system comprising:

a retractor frame comprising a first arm and a second arm;
a first blade coupled to a distal end of the first arm, the first blade having a first channel;
and
a second blade coupled to a distal end of the second arm;
wherein the first blade includes an anchor member receiving portion at a distal end of the first blade, the anchor member receiving portion slidably received in the first channel of the first blade,
wherein the anchor member receiving portion is configured to receive an anchor member capable of fixation into a bone member, and
an extension portion slidably received in the first channel of the first blade such that the extension portion directly rests atop the anchor member receiving portion
wherein the first blade has a second channel, the anchor member receiving portion is slidably received in the second channel of the first blade, but the extension portion is not received in the second channel of the first blade.
