Uterra by Illumigyn: A novel uterine manipulator for laparoscopic hysterectomies with an illuminated colpotomy cup

Abstract

Over 400,000 hysterectomies are performed annually in the United States, yet limited intraoperative visualization remains a significant contributor to surgical complications. Surgeons frequently report difficulty visualizing the cervical-vaginal junction during colpotomy, increasing the risk of injury to surrounding structures such as the bladder and ureters. Current uterine manipulators lack integrated illumination, creating a critical unmet need for improved visualization in minimally invasive gynecologic surgery.

Illumigyn developed an illuminated uterine manipulator that integrates fiber optic lighting into a familiar surgical design. The device maintains a curved rod structure and offers interchangeable colpotomy cups for anatomical compatibility. A fiber optic cable runs through the handle, delivering consistent, externally powered illumination to the transparent colpotomy cup rim. This approach enhances visibility directly at the surgical site while eliminating reliance on internal batteries, improving reliability and usability.

The design successfully demonstrates localized illumination at the colpotomy site, improving visual clarity of surgical boundaries. The transparent cup enhances anatomical distinction without obstructing the field of view. The fully disposable system reduces sterilization requirements and minimizes cross-contamination risks. The estimated production costs of approximately $578,923 and a projected unit price of ~$300 support feasibility for scalable manufacturing and market entry.

This device addresses a critical gap in women’s health by improving surgical precision and safety in hysterectomy procedures. With a projected uterine manipulator market of $696.46 million by 2031, Illumigyn presents strong clinical and commercial potential for adoption in gynecologic surgery.
