In recent years, laparoscopy has become a frequent technique employed in abdominal surgeries. Simultaneously, surgery has become increasingly complex and operating times have lengthened. Surgeons and scrub nurses must more frequently operate in standing position, with increasing physical burden. We assess the effect of the Archelis posture maintenance device, which has been developed for surgeons, in clinical situations. We measure the scopist bilateral iliopsoas muscle surface electromyogram during radical laparoscopic hernia surgery. Muscle potential decreases in the surgery with wearing Archelis. In a subjective assessment, the study participant desired its use during long surgeries. Posture maintenance devices for surgeons and improved surgical environments are important to improving surgery quality and surgeons' work environment.
