Abstract: A tubular retractor securement frame is disclosed including a mounting bracket, two flexor arms, and a device emplacement oriented to receive and hold in-place a surgical tool. The mounting bracket includes an elastically deformable plate, rails extending about orthogonal from the elastically deformable plate and about parallel to one another, and receptacles facing one another in the rails which are arranged to receive a retractor arm extending from a tubular retractor at a fixed angle. The flexor arms extend from the mounting bracket adjacent to the rails. The flexor arms are positioned so as not to occlude visualization through the tubular retractor and such that applying pressure to flex the flexor arms toward one another shifts the rails to accept or remove the retractor arm into or from the receptacles, and releasing the pressure reverts the rails so as to inhibit the retractor arm from being inserted or removed.
