摘要：
Surgical devices, systems and methods for treating tissue are provided. Also provided are systems for treating tissue and methods of treating tissue. An exemplary surgical device comprises a handle (20a) having a proximal end and a distal end； a shaft extending distally beyond the distal end of the handle, the shaft having a proximal end and a distal end； an electrode tip (45), at least a portion of the electrode tip extending distally beyond the distal end of the shaft, the electrode tip extending distally beyond the distal end of the shaft comprising a spherical end surface portion (25) and a cylindrical side surface portion, the spherical end surface portion located distal to the cylindrical side surface portion and comprising at least a portion of the distal end surface of the surgical device； and a fluid passage directed to provide a fluid towards the cylindrical side portion of the electrode tip.
