Bearing coupling for enabling the tip of a cryosurgical instrument to be rotated independently of inlet and exhaust tubes |
摘要 |
A cryosurgical instrument having a tip which is cooled by the Joule-Thomson expansion of a pressurized gas. The gas is conveyed to the tip by an inlet tube and exhausts through an exhaust tube connected to the rear of a fitting. The tip is connected to the forward portion of the fitting. The rear and forward portions of the fitting are rotatably connected by a bearing coupling which enables the tip to be rotated independent of the inlet and exhaust tubes.
