An improved neurosurgical system: New operating table,chair, microscope and other instrumentation

Summary We have developed what we call the instrument trio in the neurosurgical operating theatre: a remotecontrolled operating microscope with magnetic lock, an operating table with remote-controlled X-Y shifter, and a floating operating chair. In addition other important improvements in instrumentation have been made; they include a quick sterilization system for the operating microscope, a multipurpose head frame and an improved retractor system. The instruments and their characteristics are described in detail.
