| 摘要 |
An electrosurgery probe comprises tip, mid-, and electrical contact segments. The mid-segment is a tube open at one end, closed at the other, and an interior flow passage. An opening formed through the wall of the tube adjacent to the closed end of the mid-segment and fluidly communicating with the interior flow passage. An electrosurgery system includes the electrosurgery probe and an electrosurgery handpiece. The handpiece comprises an elongate body segment and an exhaust cap attached to the body segment. A main flow passage extends longitudinally through the handpiece, and a second passage extends longitudinally through a distal portion of the body segment. In use, the probe is removably disposed in the handpiece such that the electrical contact segment is positioned within the second passage and the mid-segment opening is positioned within the exhaust cap and in fluid communication with the main flow passage. |

1. An electrosurgery probe, comprising:
an electrically-conductive element comprising a surgical tool tip segment, a mid-segment, and an electrical contact segment, the mid-segment comprising a hollow, unobstructed tube having a wall and an interior flow passage, the mid-segment having an open distal end and a closed proximal end, wherein the mid-segment is coupled at its distal end directly to the surgical tool tip segment and coupled at its closed proximal end directly to the electrical contact segment, the mid-segment further having an opening formed through the wall of the tube adjacent to the proximal end of the mid-segment, the opening in fluid communication with the interior flow passage, and wherein the surgical tool tip segment, the mid-segment and the electrical contact segment are all comprised of at least one electrically-conductive material to enable passage of electrical current from the surgical tool tip segment through the mid-segment to the electrical contact segment. |
