Illuminated surgical retractor capable of hand-held operation and of being mounted to a fixed frame

A spinal surgical assembly comprising:

• a surgical retractor comprising a handle and a blade extending from the handle;
• and
• a screw comprising a shaft and a threaded end,
• wherein the handle of the surgical retractor has an ergonomic construction configured for hand-held use of the retractor, and the handle is further configured to attach to one or more of a fixed frame and a fixed arm of a surgical positioning device,
• wherein the blade includes at least one channel therein, the at least one channel forming an enclosed passage between a first opening adjacent a proximal end portion of the blade and a second opening adjacent a distal end portion of the blade, and
• wherein the screw is configured to pass through the at least one channel such that the threaded end extends from the second opening in the at least one channel and to secure the surgical retractor to a bone or a vertebra.

A surgical retractor comprising:

• a handle;
• a blade extending from the handle;
• a mounting adapter configured to releasably engage with the handle;
• and
• an illumination assembly including at least one direct light source provided on the blade, and one or more electrical components housed in the handle,
• wherein the handle has an ergonomic construction configured for hand-held use of the retractor,
• wherein the handle is further configured to attach to one or more of a fixed frame and a fixed arm of a surgical positioning device via the mounting adapter,
• wherein the handle includes a main portion and a curved distal end portion,
• wherein the blade extends substantially perpendicularly from a longitudinal axis of the main portion in a first direction and the curved distal end portion extends at an acute angle from the longitudinal axis of the main portion in a second direction opposite of the first direction, and
• wherein the handle is configured such that when the mounting adapter is engaged with the handle, the mounting adapter is oriented substantially parallel to a longitudinal axis of the curved distal end portion.
