Apparatus for simulating microlaryngeal surgery. The invention is particularly suited for use in the aortic arch. This bracket device is thin, compact and of very neat and simple appearance. By designing the main control unit, the first tuning unit, and the second tuning unit, regulating the two weighting parameters of the first multiple and the second multiple, and tuning the actual system, the above technical features are obtained. No caulking or painting is required because the angled flexible second member together with the vertical rigid first member seals any minor gaps and produces an attractive finished product.
