RESUMEN
With the development of laryngeal microsurgery, the requirements for the flexibility and convenience of surgical instruments are increasing. The research on related instruments has important value for the clinical application of laryngeal microsurgery. We have redesigned a gun-type tube-guide device of laser fiber by comparing the shortcomings of existing laser fiber introducers. The innovation of this design lies in its rotating nut device with adjustable laser angle and pre-bent tip. The corresponding in vitro laryngeal model experiment can realize multi-angle rotation of the instrument in the laryngeal cavity, which greatly increases the scope of laser surgery. During the operation, the rotating nut can be directly adjusted to avoid repeatedly removing the instrument to adjust the angle, which greatly improves the practicability and simplicity of the operation, which is worthy of further clinical research and promotion.
