[Development and concept of a new operatory chair]

We present a novel type of operatory chair which directs an operation microscope by remote control using infrared beams: XV, zoom, focal and accessories. The advantage of this system is the absence of transmission cables, and consequently represents an important improvement in terms of flexibility. It is a vast improvement as well for maintaining sterile conditions in the operation room. The ergonomics of this chair was especially designed for microsurgery. The adjustment and stability of the forearm has been considerably improved.
