Laparoscopic Limitations/Robotic Solutions
| Laparoscopic Problems/Limitations | Robotic Surgery Solutions/Potential | ||||||
|---|---|---|---|---|---|---|---|
| Two-dimensional vision of surgical field displayed on the monitor impairs depth perception | Binocular systems and polarizing filters create 3-dimensional view of the field | ||||||
| Movements are counterintuitive (ie, moving the instrument to the right appears to the left on the screen due to mirror-image effect) | Movements are intuitive (ie, moving the control to the right produces a movement to the right on the viewer) | ||||||
| Unstable camera held by an assistant | Surgeon controls camera held in position by robotic arm, allowing solo surgery | ||||||
| Diminished degrees of freedom of straight laparoscopic instruments | Microwrists near the tip that mimic the motion of the human wrist | ||||||
| Surgeon forced to adopt uncomfortable postures during operation | Superior operative ergonomics: surgeon comfortably seated on the control console | ||||||
| Steep learning curve | Shorter learning curve |
