为治疗喉咽部及喉部病变,作者们改进、设计了一种新的真空管冷冻治疗器械,管长35cm、直径6mm,其手柄为一能贮存300ml液氮的容器,柄与管间夹角为115～120°,用电吸引器控制液氮量,器械的前端可达-180℃低温;为在间接喉镜明视下治疗喉部较小病灶,作者另设计有一种冷冻管,前端弯成120°,使用一氧化氮致冷,可达-70℃低温的治疗器。作者们用上述二种装置共治疗Reinke喉炎、
To treat the throat and throat lesions, the authors improved and designed a new vacuum tube cryotherapy device with a tube length of 35cm and a diameter of 6mm. The handle is a container capable of storing 300ml of liquid nitrogen and the angle between the handle and the tube. For 115 ~ 120 °, with electric suction device to control the liquid nitrogen, the front end of the device can reach -180 °C low temperature; In order to treat minor lesions of the throat under the indirect laryngoscope photopic vision, the authors designed another kind of cryotube, front end bend In 120 °, the use of nitric oxide cooling, up to -70 °C low temperature therapeutic device. The authors treated Reinke laryngitis with the above two devices.
