Dr. Marwa’s uterine manipulator is used to stabilize and manipulate the uterus to improve access and visualization of the surgical area. It’s commonly used in laparoscopic hysterectomy procedures. 

The uterine manipulator is an essential instrument for mobilizing the uterus, identifying the vaginal fornices, and sealing the vagina during a hysterectomy. It also provides good access to the posterior aspect of the uterus and the cervix.
