Abstract

<p>　In this report, we describe (1) a flexible high-frequency knife (250mm), (2) shaft-rotatable forceps with a malleable tip (250mm), and (3) a suction coagulator equipped with a water pumping function (200mm) as reusable surgical instruments optimized for trans-oral pharyngolaryngeal surgery, that were developed by us in collaboration with Fujita Medical Instruments Co., Ltd. By using these devices in combination with a high-frequency electrosurgical generator VIO3 (ERBE), we have been able to perform trans-oral surgery for malignant tumors of the pharynx safely and securely. These devices are applicable not only to malignant tumors, but also to various benign diseases, which is expected to contribute to further spread and evolution of trans-oral surgery, including expansion of opportunities to learn surgical techniques in this field.</p>
