  • Surgical knives
    Patent number: 4627435
    Abstract: A surgical knife includes a handle supporting a diamond blade. An Nd/YAG laser is optically coupled by a bundle of optical fibres to the blade. The arrangement enables the blade to cauterize tissue being incised by the knife. The selection of the material of the blade and the laser provides a laser knife of extended useful life. The heating of the diamond blade by the laser provides the blade with an unexpectedly increased cutting and cauterizing performance.
