Abstract
To address the issue of declining performance over time with manual uterine manipulation during minimally invasive gynecologic surgery, we propose a novel uterine manipulation robot that offers tireless, stable, and safer manipulation. This proposed robot consists of a 3-DoF remote center of motion (RCM) mechanism and a 3-DoF manipulation rod. The RCM mechanism uses a single-motor bilinear-guided design that allows for a wide range of pitch motion (-50 to 34 degrees) while maintaining a compact structure. The manipulation rod has a tip diameter of only 6 mm, allowing it to accommodate almost any patient's cervix. The 30-degree distal pitch motion and ± 45-degree distal roll motion of the instrument further improve uterine visualization. The tip of the rod can be opened into a T-shape to minimize damage to the uterus. Laboratory tests have revealed that our device has a highly precise mechanical RCM accuracy of 0.373mm and is capable of handling a maximum load of 500g. Furthermore, through clinical testing, the robot has been proven to offer improved manipulation and visualization of the uterus, making it a valuable addition to the surgical tools available to gynecologists.
