Electrosurgical tool |
摘要 |
An electrosurgical tool for cauterizing or ablating patient tissue, which tool includes a tubular shaft which defines therein a conduit in communication with a suction source and which mounts an electrode at the distal end thereof. An electrode support element is provided at the distal end of the shaft for mounting and insulating the electrode. The support element and the electrode together define a suction opening at the treating surface of the electrode which minimizes clogging of the tool. |

1. An electrosurgical tool comprising a handle defining a proximal end portion of said tool, an elongate tubular shaft projecting from said handle and defining a hollow interior in communication with a suction source, an electrode support element disposed at a distal end of said shaft and having a portion comprising an insulating material, said support element mounting thereon an electrode configured for electrically treating tissue at the distal end of said shaft, said electrode and said portion of said support element together defining a first suction opening in communication with said hollow interior of said shaft, said first suction opening being defined by an edge of said electrode and an edge of said portion of said support element disposed adjacent said edge of said electrode, said electrode defining a second suction opening in communication with said hollow interior of said shaft, said second suction opening being wholly defined by said electrode, and said first and second suction openings permitting suction to be drawn into and through said first and second suction openings and along said shaft to the suction source. |
