1. A surgical retractor, comprising:
a single continuous structure configured as a shaft that branches into a first elongate finger with a first distal end opposite the shaft, a second elongate finger with a second distal end opposite the shaft, and a resilient lattice structure disposed between the first elongate finger and the second elongate finger; wherein the retractor has an expanded configuration and a collapsed configuration based on relative distance between the first distal end and the second distal end; and wherein when the retractor is in the collapsed configuration, spring force energy is stored in the resilient lattice structure. |
