Method of producing an electrosurgical device

摘要

A method of producing an electrosurgical device is disclosed. Opposing longitudinal clamshells are formed, and each clamshell includes a face having a generally planar major portion. Longitudinal grooves are formed in a clamshell, and an electrical conductor in a disposed in a groove. The faces are aligned to form an electrical passage including the electrical conductor in the groove and a spaced-apart fluid passage with another groove. The clamshells are welded together to form a shaft member such that the electrical passage and the fluid passage are fluid tight along a major longitudinal portion of the shaft. Electrodes are attached to the distal end of the shaft and are in electrical communication with the electrical conductor.

1. A method of producing an electrosurgical device, comprising:
forming a first elongate clamshell and a second elongate clamshell from an electrically insulating material, wherein the first elongate clamshell includes a first face having a plurality of spaced-apart grooves and the second elongate clamshell includes a second face having a second groove opposing one of the plurality of spaced-apart grooves in the first face; disposing an electrical conductor into one of the plurality of spaced-apart grooves and the second groove; aligning the first face against the second face to interlock the first face with the second face and to form an electrical passage including the electrical conductor and a spaced-apart fluid passage from another groove of the plurality of spaced-apart grooves in the first elongate clamshell; welding the first elongate clamshell and the second elongate clamshell together to integrally form a shaft member such that the electrical passage and the fluid passage are each fluid-tight along a major longitudinal portion of the shaft member; and attaching an electrode at a distal end of the shaft member to be in electrical communication with the electrical conductor and to form the electrosurgical device.
