Ergonomics: requirements for adjusting the height of laparoscopic operating tables.

摘要: Background and objectives In the last few years many new instruments devices have been developed introduced into operating room (OR). A debate has ongoing about optimal ergonomic posture for staff. From practical experience, we learned that tables cannot be adjusted adequately to allow surgeons of different stature maintain a comfortable posture. The goal this study was establish most table height particular physique surgeon types laparoscopic instrument handles he or she uses. Methods simulated model, two probands (50th [BS 50] 95th 95] percentile) used with four handle designs (shank, pistol, axial, rod). were inserted board in three angles ([IA] = 20 degrees, 30 40 degrees). Additionally elbow (EA) volunteers fixed either 90 degrees 120 degrees. For every variable (size his her angle, design handle, insertion angle instrument) board, as parameter level abdominal wall patient pneumoperitioneum, measured from floor. Results All parameters had an effect on height. lowest required cm, highest 60.5 cm. surgery-long shafted patients pneumoperitoneum-the tabletops are too high over 95% all surgeons. As skin incision wound suture performed conventional way, tabletop must adjustable up common 122 maximal difference between heights OR-table one volunteer using (BS 95, EA IA rod BS 50, axial handle) 27 Conclusion New much lower adjustability necessary fulfill requirements. use differently designed can hinder surgeon, because each requires working
