[Newly developed vacuum suction valve for microsurgery]

A vacuum operated suction appliance can be invaluable for all areas of surgery. The suction process carries a greater risk (e.g. dizziness, deafness), especially in microsurgery of the ear. A newly developed vacuum valve for microsurgery that is mechanically adjustable is presented. The surgeon operates the valve with his foot outside the aseptic area of surgery. The valve enables him to regulate the vacuum or to quickly interrupt the suction process. This allows for swifter, safer surgery. Examples of use of the device in microsurgery of the ear are described in detail.
