An Automatic Camera-Holding System for Gynecologic Laparoscopy

Development and First In Vivo Trial of EvoLap, an Active Laparoscope Positioner

“…Manual manipulation of the laparoscope is a primary cause of difficulties encountered by surgeons [3][4][5][6][7][8]. Because both hands must be used to perform the operation, manipulation of the camera must be entrusted to another surgeon or more often to a less experienced assistant.…”

“…This lack of coordination between surgeon and assistant often results in incorrect or unwanted camera motion. Holding the camera may also be exhausting in long procedures [6,7], and images become unstable [3][4][5][6][7][8] owing to hand tremors. This image instability impedes performance of goal-directed hand motions such as fine suturing [4,6].…”

“…This image instability impedes performance of goal-directed hand motions such as fine suturing [4,6]. Temporary loss of focus also occurs while the assistant performs other surgery-specific tasks with his or her other hand [8]. Less attention is paid to the laparoscope, and the distal lens can contact tissue and become clouded.…”

“…Less attention is paid to the laparoscope, and the distal lens can contact tissue and become clouded. The physical presence of the assistant might also be cumbersome in the small workspace, reducing the surgeon's freedom of motion [8]. All of these ergonomic problems tend to disturb the surgeon's concentration and result in fatigue and irritation.…”

Nach einer Studie von Leape et al [30], in der die Ursachen für Fehler und Komplikationen bei der Nutzung technischer Systeme in der Medizin untersucht wurden, arbeiteten diese in 77,2 % der identifizierten Fälle gemäß ihren technischen Spezifikationen, jedoch hatten die Nutzer Probleme mit der korAbb.…”
