First Appendectomy Using Revolve Surgical Robotic Arm

3 participantsStarted 2026-04-01

Plain-language summary

This study is testing a new surgical device called the Revolve Surgical System (RSS) during appendix removal surgery. The RSS is designed to help surgeons perform minimally invasive surgery with improved precision and stability while working at the patient's bedside, similar to standard laparoscopic surgery but with robotic assistance. This will be the first time the device is used in patients. It will be evaluated in three adults with uncomplicated appendicitis who are already scheduled to have an appendectomy. The purpose of the study is to assess whether the device can be used safely and effectively and to better understand how it performs during surgery.
