Abstract
A retractor may include one or more racks and retractor blades coupled to the respective racks via respective carriages and retractor arms. The carriages may traverse respective racks to laterally position retractor blades. The retractor blades may include tracks which the retractor arms may traverse to longitudinally position retractor blades with respect to the racks.
Claims20
A retractor system, comprising:
- a first retractor arm comprising a first retractor arm proximal end, a first retractor arm distal end, and a first retractor arm channel that extends through the first retractor arm distal end;
- and
- a first retractor blade comprising a first retractor blade proximal end, a first retractor blade distal end, a first retractor blade track that runs longitudinally between the first retractor blade proximal end and the first retractor blade distal end;
- wherein the first retractor arm comprises a first retractor arm pawl that selectively extends into the first retractor arm channel;
- wherein the first retractor blade track comprises track catches distributed between a first retractor blade track proximal end and a first retractor blade track distal end;
- and
- wherein the first retractor arm channel is configured to engage the first retractor blade track and permit longitudinal translation of the first retractor blade with respect to the first retractor arm distal end such that the first retractor arm distal end traverses along the first retractor blade track to align the first retractor arm pawl with a selected one of the track catches and secure the first retractor blade among multiple selectable positions with respect to the first retractor arm distal end.
