带有可调节的能量模式的组合超声和电外科器械以及用于密封组织和防止组织切除的方法
摘要：
一种超声外科器械(12)和密封组织的方法包括用电信号询问(114)组织，并且响应于组织反馈调节(116)超声能量或射频能量中的至少一个的电参数，以防止横切组织。超声外科器械(12)具有端部执行器(20)、轴组件(22)、主体和功率控制器(46)。功率控制器(46)操作地连接到超声刀(28)和射频电极(30)，并且被配置为引导超声刀(28)或射频电极(30)的激活。功率控制器(46)还被配置为经由超声刀(28)或射频电极(30)用电信号询问(114)组织，以提供组织反馈，并且响应于组织反馈，调节(116)超声能量或射频能量的电参数，以防止横切组织。
摘要（英）：

An ultrasonic surgical instrument (12) and method of sealing tissue includes interrogating (114) the tissue with an electrical signal and adjusting (116) an electrical parameter of at least one of theultrasonic energy or the RF energy in response to the tissue feedback to inhibit transecting the tissue. The ultrasonic surgical instrument (12) has an end effector (20), a shaft assembly (22), a body, and a power controller (46). The power controller (46) is operatively connected to the ultrasonic blade (28) and the RF electrode (30) and configured to direct activation of the ultrasonic blade (28) or the RF electrode (30). The power controller (46) is further configured to interrogate the tissue with the electrical signal via the ultrasonic blade (28) or the RF electrode (30) to provide a tissue feedback and adjust (116) an electrical parameter of the ultrasonic energy or the RF energy in response to the tissue feedback to inhibit transecting (114) the tissue.
