摘要

Support device for spreader and adjustable retraction of tissues and biological structures, coupling system for the release of the operative field, formed by a ring body (1) with the top edge (2) taken by cutouts (3) forming holes (4) eqtiidistantes to long cu00f3ncavos Out of his body, recipients of traction devices (12).They are composed of a stem (13) with cams (19) of the lock and adjustment of positioning and preu00eanseis terminals (17) and (18) remaneju00e1veis, especially developed for the project.For surgery, the ring body (1) is positioned on the surgical field (c) is open, and the clips of its upper edge (2) are fitted on the rods of tensile (13) coupled in the holes cu00f3ncavos (4) holding for its terminals (17) and (18) the superficial tissue and juxtaposed from The internal diameter of the ring body (1), releasing the operative field to the work of the surgeon.
