Abstract

Retraction of brain tissue during surgery is very sensitive to excess pressure. Often permanent damage results when pressures exceeding 20mm/Hg are applied for extended duration. A measurement system has been developed which utilizes a disposable sensor in conjunction with a control unit to measure retraction pressure. Calibration tests show that this is an effective and accurate means for measuring retraction pressure within plus 2% full scale over a pressure range of 70mm/Hg.
