Claim:
A surgical tool holder, comprising: a clamping member that comprises a clamping part defining a bore having a bore axis in a first plane and configured for receiving and clamping to a support bar; a base portion supported from the clamping member and configured for releasably mounting to a first surgical tool support in a fixed association; an incremental retraction portion supported from the base portion and comprising: a drawing mechanism configured to operably engage and incrementally draw a surgical retractor under tension, along a drawing axis that is substantially perpendicular to the bore axis and is in a second plane to avoid interference of the surgical retractor with the support bar, to a selected position and hold the surgical retractor in the selected position, and a manually operable crank member configured to operate the drawing mechanism; and an attachment portion supported from the base portion and comprising: a post having a post axis and configured to rotatably mount a yoke of a second surgical tool support in a third plane to avoid interference of the second surgical tool support with the surgical retractor and the support bar, wherein the post axis extends in a direction substantially perpendicular to both the bore and drawing axes, and a securing member operably associated with the post to releasably fix the second surgical tool support thereto, wherein the retraction portion and the attachment portion are attached to the base portion on opposite sides of the bore axis in a substantially non-adjustable relation to each other.
