摘要： Disclosed herein are improved, efficient electrosurgical probes suitable for tissue vaporization and cutting of tissue structures, more particularly for performing electrosurgical cutting, ablation (volumetric tissue vaporization), coagulating and/or modification within a body tissue, cavity or vessel or on the surface of a patient. The system and method of the present invention optionally include means for irrigation and/or aspiration of the surgical site and therefore may be used in relatively dry environments for, for instance, oral, otolaryngological, laparoscopic, and dermatologic procedures.

摘要： An electrosurgical electrode capable of achieving instant ignition in a conductive fluid and a method of conducting an electrosurgical procedure with such electrode are disclosed. The electrosurgical electrode comprises a metallic body portion of various geometries, a metallic tip and a dielectric insulator adjacent the metallic body portion. The metallic tip is recessed from the surface of the dielectric so that the dielectric material and the adjacent recessed metallic tip form a high current density zone and pocket for bubble entrapment and instant spark formation.

摘要： A complex cavity gyrotron designed for stable operation at high order modes. The device comprises circuitry for generating an annular electron beam, a coupled cavity disposed coaxially with the electron beam and having a first and second adjacent coaxial sections with the dimensions of these coaxial sections adjusted so that different modes with the same azimuthal eigen number but different radial eigen numbers are simultaneously resonant at approximately the same frequency in the two sections, and circuitry for generating an axial magnetic field within the cavity. Few, if any, combinations of modes other than the combination chosen will simultaneously resonate in the cavity thereby effecting higher order mode suppression. The present design has a low susceptibility to beam velocity spread and is effective for any combination of modes with identical azimuthal eigen numbers.
摘要翻译：一个复杂的腔室陀螺仪设计用于在高阶模式下稳定运行。该装置包括用于产生环形电子束的电路，与电子束同轴设置的耦合腔，并且具有第一和第二相邻的同轴部分，其中这些同轴部分的尺寸被调整为使得具有相同方位角本征数但不同径向的不同模式特征号在两个部分中以大致相同的频率同时谐振，以及用于在腔内产生轴向磁场的电路。如果有的话，除了所选择的组合以外的模式的组合将在空腔中同时共振，从而实现更高阶模式抑制。本设计对光束速度扩展的敏感度低，并且对于具有相同方位角本征数的模式的任何组合是有效的。
