Summary
The Songkla Uterine Manipulator (SUM) is a low-cost device for laparoscopic surgery, enabling improved uterine positioning and visualization. Early results show successful use in various gynecological procedures with good outcomes.
Area of Science:
- Minimally Invasive Gynecological Surgery
- Surgical Instrumentation Development
Background:
- Laparoscopic procedures require specialized instruments for optimal visualization and manipulation of pelvic organs.
- Existing uterine manipulators may have limitations in terms of cost, complexity, or range of motion.
Purpose of the Study:
- To introduce and evaluate the Songkla Uterine Manipulator (SUM), a novel, simplified, and low-cost device designed for laparoscopic gynecological surgery.
- To assess the efficacy and safety of the SUM in various laparoscopic procedures.
Main Methods:
- The Songkla Uterine Manipulator (SUM) features a stainless steel rod construction with a pivot head, locking system, and a 4.7 mm diameter obturator in multiple lengths.
- The device allows for significant uterine anteversion (up to 95°) and lateral motion (up to 45° bilaterally).
- A spring hook is incorporated for retention with a tenaculum.
Main Results:
- The SUM was utilized in 150 laparoscopic procedures between December 1996 and December 1999, including tubal sterilizations, adnexal surgeries, and hysterectomies.
- Excellent visualization of pelvic organs, including adnexae, was achieved in all cases.
- No instances of trauma to the vagina, cervix, or uterus were reported during the study period.
Conclusions:
- The Songkla Uterine Manipulator (SUM) represents a simplified, low-cost uterine manipulation solution for laparoscopic surgery.
- While early results are promising, further modifications are recommended, including a cervix-retaining mechanism and solutions for potential gas leakage during laparoscopic hysterectomy.
