A novel vaginal manipulator for identifying vaginal canal separation line by visible and near-infrared transillumination light: PHARUS Pipe.

Introduction: In total laparoscopic hysterectomy, a uterine manipulator with transillumination functionality is often employed as an instrument to visualize the vaginal canal demarcation line. However, the utilization of this device necessitates an external white light source and a fiber optic cable. In this study, we developed a prototype vaginal manipulator (PHARUS Pipe) with a simpler configuration to visualize the vaginal canal separation line.
