ABSTRACT:
Apparatus for fixing retractors in an adjustable, predetermined position relative to a patient on an operating table. The apparatus comprises an anchor frame including a base member having at least one extension member projecting substantially perpendicular to the base member. A plurality of spaced apart, inwardly projecting anchor rings are serially arranged along the anchor frame, and a support frame, including upstanding post members is connected for supporting the base member of the anchor frame. Legs are adjustably clamped to the post members, the legs in turn being adjustably connected to the operating table. The adjustable connection of the legs to the post members is such as to clamp the post members and thus the anchor frame at a preselected and predetermined height relative to a patient on the operating table. Resilient bands are connected to preselected ones of the anchor rings, which bands include retractors thereon for separating an incision under a predetermined tension and with a predetermined opening desired by the surgeon.
The purpose of this abstract is to enable the Public and the Patent Office to determine the subject matter of the technical disclosure of the application. This abstract is neither intended to define the invention of the application nor is it intended to be limiting as to the scope thereof.
