As a key energy device in modern minimally invasive surgery, the radiofrequency-ultrasonic scalpel, featuring the simultaneous delivery of both radiofrequency and ultrasonic energies, boasts significant advantages such as minimal trauma and rapid recovery, thus being widely used in clinical practice. Compared with traditional instruments, it performs better in reducing operation time, intraoperative bleeding, and postoperative complications. Currently, this device has played an important role in multiple fields including general surgery, urology, gynecology, and neurosurgery. Although domestic research and development have achieved remarkable outcomes, with domestic substitution realized in some fields, issues such as reliance on imported core materials and limited expansion in the international market remain. This review mainly summarized the structural principles, application scenarios, and innovation directions of the radiofrequency-ultrasonic scalpel, analyzed its prospects, and put forward improvement suggestions, aiming to provide references for its subsequent development.
