| 摘要 |
A method and apparatus for improving the safety of a surgical procedure involving delivery of laser energy to a tissue, involves enhancing or increasing the detectability of radiation emitted by the tissue or any portion of a surgical instrument or device by providing a sacrificial material that absorbs radiation emitted during the surgical procedure, increasing the temperature of a surface on which the material is disposed and/or causing damage radiation to be emitted in a way that can be detected by monitoring the temperature of the surface and/or radiation, including infrared and/or visible light, emitted by the surface. In a preferred embodiment of the invention, the radiation absorbing material is a sheath arranged to surround the fiber.
