Abstract
A surgical instrument for providing suction and/or irrigation has a surgical tool or electrode tip mounted within the wall of an elongated housing or cannula such that the passageway through the housing is substantially unobstructed. A mounting notch is formed in the elongated housing and the surgical tool is formed with a mounting tab that matches the mounting notch. The mounting tab is positioned into the mounting notch and is substantially flush with the wall of the elongated housing. The mounting tab is then secured to the wall of the elongated housing, for example, by laser welding. The surgical tool can be formed with various different tip shapes including, but not limited to, a J hook, an L hook, a spatula, a needle, and a ball. In one example, the surgical instrument is used as a laparoscopic electrosurgical instrument and the elongated housing and surgical tool are made of electrically conductive materials.
